5 Claims.
The present improvements are directed to a machine through which a web of sheet material such, for example, as roofing paper, drawn from a supply roll, may be advanced a. predetermined distance concurrently with a winding of its leading end into a smaller roll, movement of the web being halted automatically when a measured length thereof has advanced to permit of severing of the web and removal of the roll containing a desired length of the material. A mechanism for this purpose can be used to advantage in preparing for the market serviceable rolls of roof ing paper or other material the lengths of which may vary considerably.
The features of improvement with which the present invention is concerned relate to an electrical mechanism in which is comprised a plurality of circuits each with a controlling. switch, the closing of a selected switch operating to advance the web through a predetermined distance while the leadingend thereof is being wound into a roll upon a mandrel. When the web travel is halted the wound portion thereof may be severed with the aid of electrical mechanism. The starting and stopping of the several feeding mechanisms is under the control of electrical instrumentalities as well. These several operating units are interconnected electrically in a novel manner, all as will be fully explained erein after.
Various objects and advantages, as will appear in the succeeding specification and claims, are attained by th suggestive embodiment of our vention which. is illustrated in the accompanying drawings in the manner following:
Figure It is a plan View of the machine its en a side elevation thereof; a side elevation, partly broken away. ontaining the switch mechanism;

Figs. 5 and 6 are details in section taken, respectively, on lines 55 and 6 6 of Fig. i;

8 is a fragmentary sectional View taken on line 8--t of Fig. l; and
Fig. 9 is a fragmentary View in elevation taken as indicated by the line Q-9 of Fig. l.
The present roll winder may be applied to a machine having a bed comprising spaced horizontal I-beams III, II and I2, which are carried upon supporting legs 13. A web W, which enters from transverse section taken on line a roofing machine or is unwound from a reel (not shown) is adapted for travel through the machine to be acted upon by various agencies which are mounted upon the bed between the beams l0 and H. To one side, above and below the beams l l and I2, we have located some of the transmission, controls, etc., all as will now be explained.
Proceeding from right to left (as viewed in Figs. 1 and 2) the web advances successively under and over idler rolls I 5 and I6; thence between opposed pairs of measuring Wheels I! and i8, one above the other, and mounted respectively upon shafts l9 and 20; thence between a plurality of opposed pairs of pressure wheels 2i and 22 of which the former (the upper) are mounted each upon a weighted arm 23 pivoted as at 24; thence between a pair of shafts 25, 26 on which are mounted an anvil roll and a special diamond point head with slitters, respectively, the head containing any shape of knives desired to longitudinally slit the web; thence between a pair of spaced feed rolls 21, 28 for pulling the web through the machine; thence over a table 30 (Fig. 6) with which is operatively associated a guillotine knife 3| under the separate control of the operator; thence in measured lengths over a platform 32 which is mounted to swing upon a shaft 33 in response to an upward force applied to a handle 55-, thence on to a gripping man drel we) it is gripped and wound into a roll. These several are interconnected to operate in timed relation.
From a motor power is transmitted through belts to a pulley 3? on amein shaft so equipped clutch t wi h connection with a second t5 transmits power to a compensating clutch in connection with the mandrel the gear drives a meshmg gear it upon the shaft for one of the iower: feeding rolls; and from a sprocket wheel ll mounted on the same feeding roll shaft 9. chain it runs over a sprocket $9 on the adjacent feeding roll shaft whereby both pairs of feeding rolls are operated in unison. The two idler rolls l5 and it past which the sheet travels may be shifted endwise in unison when interconnected by a chain-sprocket assembly lit as shown in Fig. 1. Also the shaft 5| which mounts the lower set of pressure wheels 22 may be equipped with a sprocket wheel 52 adapted to be driven from the sprocket 4i hen a chain drive connection (not shown) is established therebetween, in which event the chain 48 is not used.
The shafts for the upper feeding rol1s 25 and 21 are mounted in bearing blocks 55 which are 5 vertically slidable in supporting guides 50. With the aid of screw and/or tension mechanism each pair of feeding rollsmay be maintained under pressure, in accordance with common practice. In like manner, the upper measuring wheel shaft 14 I9 is adjustable toward and from its lower companion shaft 20. through the several driving connections heretofore described, the web W is'drawn through the machine by frictional engagement therewith of 5 the feeding rolls, and in so proceeding the web imparts to the measuring wheels a rotary motion which continues through a peripheral distance that is determined by advance of the web. Advantage is taken of this fact to measure selected 2% lengths of the traveling web which is concurrently rewound upon the mandrel, and to oper- =ate.the guillotine knife to sever the measured length of the web which is temporarily halted for this purpose. For accomplishing these ends we 5 use certain mechanism which is electrically controlled, a.ll as will now be explained.
Upon the measuringwheel shaft I9 is mounted a gear 59 in disconnectable driving relation with a collar 30 that ismounted fast on this same 30- shaft; in mesh with this gear is another gear BI with an associated worm 02 adapted to drive a worm wheel 63 on a toothed shaft I54 which extends longitudinally through a control box 65 containing a multiple switch mechanism. The 35- switch box, as shown (see Figs. 3 and 4), is cylindrical with heads 66 at its opposite ends interconnected by tie rods 61. In spaced relation transversely within the box are a plurality of fixed plates 68, each mounting (1) a stud 69 upon which is rotatably supported a pinion 10 in mesh with the toothed shaft 64, and (2) a micro-switch III, such as shown in Patent 1,960,020 from which extends a retractible actuating finger 12, whose exposed end lies in the path of a pin 13 which 45 is carried on the pinion near its periphery. As
suitable conductors, an electrical connection is extended from each micro-switch to a single-pole double-throw toggle switch I4 whose operating lever 15 is disposed exteriorly of the box con- 59) vem'ent for manipulation. The several pinions are shown as increasing progressively in size according to their positions lengthwise of the box, the associated micro-switch finger in each instance being mounted at such an elevation that 55 its actuating finger is disposed about radially of the pinion, so that as the pin 13 passes the finger the latter is depressed to effect a closing and immediate reopening of the switch.
The clutch and brake mechanism in the cross 59 shaft are interconnected as best shown in Fig. 5.
For operating the movable clutch element connection is made therewith by the weight end of a bell crank lever 16 mounted fast on a rock shaft 117, a link connection 10 extending from the power end 19 of the lever to a. toggle or other device 80 at the ends of the band formingpart of the brake mechanism. A connection 8| extends from the power end of the lever to the core of a solenoid A which may conveniently be mounted in a frame 7 depending from the machine bed. According to the mechanisms just described, the solenoid, when actuated, will release the clutch concurrently with application of the brake so as to halt quickly all operation of (1) the feeding rolls, and (2) the 75 winding mandrel.
In response to power applied Referring now to Fig. 6, the guillotine knife 3| is carried upon an angle bar 85 which is supported at spaced points at the upper ends of a pair of guide rods 86 each having an adjustable collarnut 81 against which an upward pressure is ex- 5 erted by a compression spring 88 which bears against the machine frame. The lower end of each rod is fitted with a yoke 89 which is pivoteclly joined to a lever 90 (of the second class) having for its fulcrum a pivoted connection 9| with a fixed bracket arm 92. The power end of the lever is joined at 93 with a. link 94 adjustably connected to the core of a solenoid B. Two such solenoids may be employed, one in connection with each rod, and both electrically interconnected, so that, upon operation thereof,'the two rods are pulled down in unison to cause descent of the knife with a consequent shearing of the web.
Referring now to Fig. 'I which shows a diagram of the wiring connections, the motor M is "connected to-a suitable power line by means of a switch 95 and leads 96, 91. These leads go also to a magnetic contactor relay 98 and are then connected to the brake solenoid A through leads 99-, and a switch I00. This switch which is normally held open by a spring IN 'is adapted to be closed by a solenoid I02 one side of which connects to one of the leads '90 and the other to the lead SIthrough a switch I03 which is oper- 3o ated by an arm I04 on the shaft 11 (Fig.1). This switch I03 is closed during'the winding operation as will later be described.
A lead I05 connects one of the main leads 01 with a bus bar I00 from which connections are made to all of the micro-switches 1I. Each micro-switch is adapted to be connected to one end of a switch bar I01. A series of switches 14 (Fig. 3) which may be of the toggle type are connected in series with each'other and joined through a lead I08 in series with the switch I03.
Thus it will be seen that as each one 'of the switch levers 15 is thrown,- that switch will be connected to its corresponding switch bar I01. With the switch I03 closed, the motor will be in operation as will be presently explained, and as the web advances and is wound on the mandrel, the toothed shaft 64 (Fig. 3) is rotated, thereby rotating all of the pinions 10. The result is that the micro-switches II will be closed successively, and when the micro-switch corresponding to the closed switch 14 is closed, current will fiow through the switch bar I01, through the closed switch I03, and will energize the relay I02 thereby closing the switch I00, thus energizing the brake solenoid A-which disengages the clutch in connection with the winding mechanism. The brake is simultaneously applied, thereby bringing the winding operation to a halt. The micro-switch instantly opens so as to be ready for succeeding no operations.
The next step is to sever the web by means of the knife 3I. This is done by'energizlng the solenoids B. Referring again to Fig. 7, the solenoids B are shown as connecting through a lead 5 I20 with the power lead 91 and through a lead I09 with a switch H0 in acontactor III, the
opposite side of the switch connecting through a lead I I2 with the other main power lead 96. The switch .0 which is normally held open by a spring H3 is adapted to be closed by a solenoid 4 which connects on one side with the lead H2 and on the other side through a lead 5 with a hand switch 6, and thence through a lead I III with the lead I20 in the contactor II'I. The 15 Operator severs the web, after its motion has ceased, by closing the switch 6 thereby causing current to flow through the solenoid Ill to close the switch III), thus energizing the two sole- 5 holds B.
The mandrel comprises a jaw 35" movable radially so as to grip or release the web. To insert the web, the law should recede, and the open space thus afforded should align with the web,
0 as shown in Fig. 6: The mandrel carries a cam II8 (Figs. 1 and 8) having two faces either of which is adapted to be engaged by a detent H9 pivotally maintained at 33 and operated by means of a link I2I from a foot lever I22 pivotally mounted at I23.
In order to reset the mandrel the operator applies pressure to the lever I22, thereby raising the detent II9 from the normal dotted line position of Fig. 8 to the full line position therein shown. While holding the detent in that position, the mandrel is rotated by momentarily throwing in the clutch as will presently be described, thereby bringing the cam I I8 to the position indicated in Fig. 8 where the mandrel occupies the rotative position shown in Fig. 6. At the same time the web advances a short distance in response to movement of the feed rolls. To' guide the web into the opening between the two halves of the -mandrel, the operator may grasp the handle 34 so as to raise the table 32 to the proper height to permit the web to slide in between the two halves of the mandrel, as shown in Fig. 6. Movement of the web is thereupon stopped by throwing out the clutch after which the foot may be re- 5 moved from the lever I22.
The movable jaw of the mandrel is opened and closed by means of a rod I24 extending axially through the mandrel shaft, as shown in Fig. l and adapted to be operated by a lever I25 which 40 is under control of the operator. The details of this gripping mechanism form no part of this invention.
Manual control of the winding mechanism is efiected by the rock shaft 'I'I which operates the clutch operating lever 16. This shaft has at one end a lever I26 which connects through a link I21 with a hand starting lever I28 (see Figs. 1 and 2). It carries also the arm I04 for operating the switch I03, so that, when the clutch 38 is disengaged, the switch I03 is open as well. When the operator desires to start operation of the mechanism, the lever I28 is moved to the right, as shown in Fig. 1, thereby throwing in the clutch 39 and at the same time closing the switch I03. The web advances at a uniform rate and, since the rotative speed of the mandrel on whichit is wound will depend upon the diameter of the roll which varies as the roll builds up, provision is made to drive the mandrel somewhat faster than the speed of the web at the smallest diameter; the resulting slippage in the mandrel drive is taken care of by the compensating clutch 45 in a well known manner.
As indicated in Fig. 3, the several clutch op- (j erating switch levers I5 are made to co-operate with the pinions ID of diiferent sizes so as to provide means for stopping the winding operation when any selected one of many lengths of the web is wound on the roll. Each switch lever 70 is therefore correlated to a given length of web travel. In each instance the length of web so wound will correspond to one complete revolution Thus a very simple, rapid, and accurate means is provided for electrically controlling the distance of web advance concurrently with a rewind operation thereof. To determine the length of web which will be so rewound in each operation, 5 it is necessary only to pull a selected switch by which everything else is controlled. For example, to effect a change in each web advance will require merely that the appropriate switch be thrown. 10
