APPARTUS FOR PRODUGING RQLLS OF' NONFRAYIN G MATERIAL.

Application led February 1G),` 1924. Serial No. 693,337.

The present invention is a method and apparatus for the production of bolts or rolls of material having the longitudinal edges ofthe materialtreated with a liquid of ad- 5 hesive material to prevent fraying or ravelling of the edges.

It is an old-and well known practice in the art to cut rolls or bolts of piece goods, of relatively large width, by appropriate a1?- paratus into a plurality of woundbolts or rolls of material. These goods or strips are used for various purposes, such as piping and 'trinnning of garments, typewriter ribbons, and the like, and an adhesive or other liquid is applied to the edges of the material or strips while in its wound or rolled condition to prevent fraying or ravelling of the edges. It is also old in the art to cut these goods or tape from straight laid material or from material on the bias, accordingly as the use and requirements to which the goods or tape are put necessitate. In both cases, however, the unselvaged edges of the material 'or tape will fray if not made lfast in some appropriate manner. It has long been the practice to apply a suitable liquid or adhesive to the edges of the material while in wound or'roll form with a hand brush, but this process is slow as only one side of the roll can be treated at a time, and the liquid is not uniformly spread.

It is the object of the present invention to overcome these drawbacks and to apply an even coating or film of unravelling liquid to both sides of the roll simultaneously.

The invention resides in the method employed in producing rolls of non-ravelling material or strips, and in the novel structure of one form of apparatus specifically adapted for carrying out the method.

The process for carrying out the invention Yconsists briefly in cutting piece goods, either i straight laid or on the bias, transversely, to produce a plurality of rolls or bolts of mate- 'rial 22 (Figs. 7 and 8) then treating the sides of the bolts or rolls of material with an edgebinding material, such as a liquid orsuitable coating, by passing the bolts or rolls edgewise between rollers or other suitable applilcator ,(Fig. 4), which will'apply the edging material to the sides of the roll on the exposed edges of the material,- whereby simultaneously the opposite side edgesof the material are treated with the edge-binding material.' The rolls are thn permit-ted to dry and subseucntly ready for packing or use, thus prouclng non-ravelling edges m on the tape or strlp as shown in Fig. 8. This method conten'lplates wrapping or. applying about the circumferential surface' of each individual roll', a protecting covering, y (Fig. 7) suchas paper or the like, to protect the face of the material from soiling or from excess amounts of non-ravelling binding material during the treating steps of the process, or in a plying the covering about the bolt or roll be ore the smaller rolls lare c ut therefrom.

Obviously this invention permits the utilization of a great variety of instrumentalities for producing the desired results and it will therefore be understood that, by disclosing herein certain particular forms of structure, we confine ourselves thereto and to the operation to be performed, only in so far as they 'carry into effect the principles of the invent-ion. l

The accompanying drawings illustrate. the preferred form ofthe construction, as at present devised, for carrying out the steps of the novel method of producing rolls or bolts of material or tape having alrough edge treated to prevent ravelling, but it is to be understood that the apparatus is susceptible to many changes/in construction and arrangements of p-arts without departing from the spirit of the invention.

In the drawings: Figure l is a side elevation of the machine. Fig. 2 is a plan view of the machine. Fig. 3 is an elevation of the machine looking at the'opposite side thereof.

Fig. 4 is a longitudinal sectional view taken through the machine,- substantially on line 4 4 of F ig. 2. f

Fig. 5 is a transverse sectional view taken substantially on line 5 5 of Fig. 2.

Fig. 6 is a similar view to Fig. 5 taken substantially on line 6-6 of Fig. 2. n c

Fig. 7 is a cross section through a roll'or rolls of material or tape after it has passed through the edging material and surrounded by an outer protecting covering, and

Fig. 8 is a prespective view-'of a roll of material or tape. afterv having `been subjected parts of the machine are mounted, said frame being supported, in the present instance, by the legs 2.

Arranged pair of rollers 3 and 4 journaled respectlvely 1n bearings 5 and 6. The bearings 5 are stational-il)T mounted on the framel while the bearings (i are slidably mounted, whereby the rollers may be. adjusted relatively to each other to vary the openingsl or passage het wecn them. '.lhe two bearings 6. on opposite sides of the frame, aire connected by a rod 7 and a bar 8 which will permit the hearings to be shifted in unison, the under face of the bearings beinggrooved to .receive a rib 9 on the frame. However, any other suitable construction maybe provided. The adjustment of the bearings 6 is effected by a rod 1() threadingly mounted in one end of the frame, as at 11, and having` a swivel connection with the bar 8.

Arranged under each of the rollers 3 and 4 and between their respective bearings are pans 12 and 13 respectively, which are shown as substantially identical in construction, and

i are designed to contain a. suitable quantity of the edge binding material, such as a suitable liquid or adhesive. The pan 12 is suspended at one end by hooks 14 engaging one of the cross rods 15, connecting the stationary brackets 5, the other end portion of the pan resting upon a support 16, which is adjustable through the slot and thumb screw connection 17 on the frame 1 to permit the pan to be adjusted with relation to the roller 3 in order that the roller may enter the liquid therein, and so that its circumferential surface will be covered or coated therewith.

The pan 13 is substantially identical with the pan 12 except for its manner of support and specific manner of. adjustability with re spect to the roller 4. In this case the pan 13 is adjusted by the thumb nuts 18 on the bolts 19 which extend from the bearings 6 through slots 20 in the frame 1, and through a supporting bar 21 upon which the pan rests, see Fig. 6. By this construction the pan 13 is adjustable with the bearings and moves therewith.

It will thus be seen that the rollers 3 and 4 are readily adjustable to be separated sufficiently to correspond with the width of the roll of material or tape to be passed through themachine, and to properly feed the rolls edgewise therethrough as indicatedl in Figs. 1 and 4. By reason of the rollers 3 and 4 dipping into the adhesive in the pans 12 and 13, their circumferential surfaces will be coated f with a film of the edging material and the transversely upon thc frame is a Spri n gs 26 are i ntcrposed between the bearings 5 and and the block 24 to act in opposition to the adjusting bolts 25, whereby the wiping rollers 23 are moved away from the rollers and 4 after the bolts 25 are correspondingly adjusted, there being suitable hand wheels or grips 27 on the adjusting bolts 25.

The wiping rollers 23 are each rotated :from their resjwctive roller 3 or 4 by gearing 23L and 23" respectively, the depth of the teeth between meshing gears being suflicient to permit the required adjustment therebetween. In lieu of this drive connection any other may be supstituted which will perform the same resu ts. v

It will thus be seen that as the rolls 22 are dropped between the rollers 3 and 4, they will feed the same therethrough and at the same time apply to the opposite sides of the roll, and therefore to the opposite side edges of the material or tape composingthe roll, a film or coating of suitable edging material which will be partially absorbed by the edges of the material or tape, and which when dry will hold the threads at the raw edges thereof intact.` against fraying or ravelling as shown at m in Figs. 7 and 8. It will be also observed that the amount of adhesive to be applied to the sides of the rolls can be regulated by re.

duing or increasing the film on the'rollers 3 an 4:

The rolls 22 may be fed through the rollers 3 and 4 as many times as is found sufficient to effectively treat the side edges thereof, and it will be obvious that by this method and apparatus the work can be done efficiently with a greater saving of time and labor than by the present method of applying the adhesive by hand to each roll.

A number of rolls canl be fed through the machine at the same time, according to the length of the rollers 3 and 4. To this end a suitable feeding means is provided y which may take any suitable form, however, inthe present instance consists of an endless conveyor 30 having the rolls arranged thereon in rows of three or four to the row. These rolls are fed from the conveyor to a guiding throat- 29 through which they gravitate to a point b-etween the rollers. After passing through the rollers they are discharged upon a suitable chute conveyor 42, down which they roll to a drier. V

The means for operating the applying rollers 3 and 4 consists of a shaft 31 suitably journaled on the frame 1, as at. 32, and being driven from any suitable source of power:

The thro'at ,29 consists of two operable i parts aand b, the former being stationarily mounted and the latter being supported from the bearing blocky 6 and movable therewith, so as to increase or decrease the interior area of the throat to accommodate the size of rolls to be fed through the machine.- The side edges of the throat are formed with flanges c,

which substantially close the sides thereof,-

and insure the delivery of the rolls between the rollers The roll 3 has on one end of its axis a beveled gear 33 meshing with beveled gear 34 fast on the shaft 31. The roller 4 has a beveled gear 35 on one end of its axis meshing with a beveled gear 36 slidably keyed' on the shaft by means of the key` 37. The gears 35 and 36 are maintained in mesh by a bracket arm 38 secured to t-he slidable bearings 6, the outer end of the bracket 38 having a fixed bearing in which the gear 36 is journaled so that it will at all times mesh with the gear 35 irrespectively of its position on the shaft;

As an auxiliary lock to maintain the bearings 6 in their adjusted positions, bolts 39 eX- tend through the bearings 6 and through the slots 20 in the frame 1, andy have an anchor late 41 at their lower ends, the upper ends of the bolts 39 being threaded and receiving lock-nuts 40 which will bear against the `top surface of the bearings 6 and bind the parts in their properly adjusted positions.

After the rolls 22 have passed through the coating members or rollers 3 and 4 they are discharged edgewise onto an inclined chute for platform 42, downwhich they will roll to a suitable drier, or collecting devices, not shown, in order that rolls 22 may not fall over sidewise after being discharged on the chute 42, guides 43 and 44 areprovided, the

guide 44 being adjustable to increase or decrease the width between the guide to accommodate the width of the rolls 22 being treated. The guide 44 is shown as being adn justable through/the set-screw 46 movable 1n the slot 45. .l s
