United rates Patent 9 ASSEMBLY OF SERIES-CONNECTED ENVELOPES AND METHOD OF MAKING SAME Theodore H. Patton, Chester, Conn., assignor to Uarco Incorporated, a corporation of Illinois Application February 11, 1954, Serial No. 409,595 Claims. (Cl. 229-69) This invention relates to an assembly of series-connected envelopes and to a method of making the same.
Modern automatic business machines, such as typewriters, addressographs and the like, may use envelopes in continuous strip form. Such continuous strips are more economical and their use results in a saving of time and labor.
One form of such strips now in use is an assembly of series connected envelopes made up by various methods. In one method complete envelopes are separately made and then detachably connected together in series by detachable marginal feed bands.
In another method envelopes are formed in series by bringing together two webs of envelope material. One of the webs is provided with some heat-sealing adhesive, and heat and pressure are applied at appropriate places to form envelope pockets. Heretotore, it has only been possible by the latter method to form end flap envelopes.
The primary object of the present invention is to provide an assembly of series-connected top flap envelopes in which the successive envelopes are formed by bringing together two Webs of envelope material and joining them at appropriate places.
Another object is to provide a novel method of forming anassembly of series-connected top flap envelopes.
A further object is to provide an assembly of seriesconnected envelopes which, when detached, have top flaps adapted to be tucked into their respective envelope pockets.
Still another object is to provide a novel, yet inexpensive, method of forming top flap business type envelopes in which the successive envelopes are formed by bringing together two webs of envelope material, one web being of ladder-like construction, and joining them at appropriate places.
The preferred embodiment and the preferred method of making the same are illustrated in the accompanying drawings, in which:
Fig. 1 is a diagrammatic perspective view illustrating the steps in the method of forming an assembly of seriesconnected envelopes;
Fig. 2, a plan view of theface of an envelope detached from the assembly;
Fig. 3, a plan view of the back side of the envelope in Fig. 2;
Fig. 4, a sectional View taken as indicated on line 4- -4 of Fig. 3;
Fig. 5, a fragmentary plan view of the top web of envelope material in the assembly;
Fig. 6, a fragmentary plan view of a portion of the bottom web of envelope material in the assembly; and
Fig. 7, a fragmentary plan view of the two webs in superposed position.
In the method and embodiment illustrated, a pair of layers or webs 8 and 9 of envelope sheet material are unwound from roll stock 10 and 11. One of the webs may be a heat-sealing, adhesive-coated material which, when subjected to heat and pressure in appropriate places, will secure itself to the other web.
ice
Before bringing the two webs together, a die-cut is made in-one of the webs between its envelope supporting m'arginal portions 13 and 14. As herein shown, the'die-cut" slug, usually removed by means of air jets (not shown), leaves a generally elongated portion 15 large enough to expose the full top flap area 16 of the superposed web 3, The longitudinally spaced, transversely extending, cut-out portions 15 create a regular'ladder-like effect in the lower web 9, the rungs of the ladder being the back portions 17 which ultimately make up the back side 18 of each of the envelopes.
If printed envelopes are desired, the top Web. is next passed through a printing unit, not shown, where its top side, later to become the face or from Hot the finished A envelope, may be printed.
The sides 20 and 21 of the envelopes and the marginal supporting portions 13 and 14 are then heat-sealed under pressure by passing the webs between the hot metal bars 22. A bottom seal 23 is similarly formed in each envelope by a pair of transversely extending hot metal bars 24. This sealing operation forms a series of regularly spaced envelope pockets 25 in the advancing strip.
This type of sealing means is adapted for use with a press, for example, a New Era Press, through which the webs are advanced by intermittent movement. It is clear that other similar heat-sealing means could be devised to suit the particular occasion. For example, the Webs may be fed into a press which advances them at a uniform 1 speed. Rollers, operating in timed relation to the ad- I vancement of the webs, and having heating bars extending transversely of the web, may. be used to seal the bottoms of the envelope pockets. Annular heating elements encircling both ends of the roller can be used to seal'the envelope pocket sides and the marginal edges of the webs.
A series of regularly spaced apertures 26, providing a pin-feed strip, are next punched in the marginal supporting portions 13 and 14 to accommodate devices having a pin-wheel feed.
A die-cut is then made in the top web 8 as indicated at Suitable means are generally provided to enable the envelopes to be detached from their marginal supporting portions13 and 14 and from each other. Lines of weak-' ening 29 extend longitudinally of the webs to provide 1 lines of separation between the envelope pocket sides 20 and 21 and the marginal supporting portions 13 and 14, and transverse lines of weakening 30 provide lines of separation between the envelope bottom 23 and the top edge of the envelope flap 16. Detached envelopes, as I illustrated in Figs. 2, 3 and 4, are formed by merely separating the flap from their marginal supporting portions 13 and 14 and from each other along the lines of weakening 29 and 30. p 7 p If desired, the top envelope flap 16 may be creased at its base, as indicated at 31, to facilitate folding, and the outer edges of the marginal supporting portions 13 and" 14 may be trimmed, as indicated at 32 and 33. After trim-1,. ming, the webs are folded on their transverse lines of and the successive envelopes may be addressed by merely advancing the strip through the machine.
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary 1imitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.
