Abstract

In order to prevent excessive delamination, peeling, or shredding of the carrier web of a continuous envelope assembly adjacent the glue spots, especially when the envelopes are machine detached, an opening or weakened portion is formed in the carrier web closely adjacent the trailing side of such glue spots. These portions may take various forms: slits, perforations forming interrupted slits, holes of various shapes, or even extremely heavily scored lines; all of which terminate any tears which might occur, almost at their incipiency.

United States Patent [56] References Cited UNITED STATES PATENTS 2,535,537 12/1950 Heywood 229/80 3 ,273,7 84 9/1966 Porter 229/69 Primary ExaminerDavid M. Bockenek Attorney-Watson, Cole, Grindle & Watson ABSTRACT: In order to prevent excessive delamination, peeling, or shredding of the carrier web of a continuous envelope assembly adjacent the glue spots, especially when the envelopes are machine detached, an opening or weakened portion is formed in the carrier web closely adjacent the trailing side of such glue spots. These portions may take various forms: slits, perforations fonning interrupted slits, holes of various shapes, or even extremely heavily scored lines; all of which terminate any tears which might occur, almost at their incipiency.

o o u c v o o o 0 ID 0 o I 1, O I o --c I 6, 07A 0 o o I I H 0 B o o 3 /4, itc Z 0 I o o A po o C o o I o B o l 0 2 [H] L 2:=--C =55 Z 0 9 .A u /o 2 T i 2 o c o D Z 1 3 o c o o o o ?A' T T o CONTINUOUS ENVELOPES This invention relates to continuous envelope assemblies comprising a carrier web to which a series of envelopes are spot-attached, as for example, by dots of adhesive.

Such assemblies, which may be exemplified by that disclosed in the US. Pat. No. 3,273,784 to V. V. Porter, are now detacher which successively separates the envelopes from the carrier web at the glue spots. One form of detacher of this general character is disclosed in the copending application Ser. No. 794,293 of R. W. Winston, filed .Ian. 27, I969.

In the use of many types of detaching apparatus for the con tinuous separating of envelopes from a carrier web, tearing or delamination of portions of the carrier web occur with the result that the separated envelopes carry with them hangons" comprising shreds or strips torn or peeled from the web and sometimes being of considerable length and presenting an untidy appearance not in keeping with the aesthetic consideration necesary for prestige top-quality stationery.

It is therefore the principal object of the invention to provide means for minimizing or eliminating the fonnation of such hang-ons or delamination shreds by interrupting the tearing in its incipiency at or adjacent to the trailing sides of the glue spots.

More specific objects of the invention reside in the nature of certain embodiments of the tear-terminating means. They may take the fonn of straight slits extending transversely of the line of feed of the web, interrupted slits formed by perforations,

holes of various configuration, oreven in some cases heavily scored lines. I I

Other objects and features of novelty will be apparent from the following specification when read in connection with the accompanying drawings in which one embodiment of the invention is illustrated by way of example.

In the drawings: I I r I FIG. 1 is a fragmentary plan view of an envelope assembly I embodying the principles of the invention;

FIG. 215 a In pcrspecuve ofa p0 on ofa similar as described herein may be made without departing from the scope of the invention as defined by the following claims.

sembly illustrating a common fault in the prior art; 1

FIG. 3 and enlarged FIGS. 4 and 5, are detail views of one machine which may be used to separate the envelopes from the carrier web; and 1 FIG. 6 is a composite of several examples of the novel tear stopping features. I 1

In FIG. I of the drawings, acarrier web is indicated at A and is provided with a series of feed holes A along each margin for being shredded away and constituting an undesirable hangon" which mars the appearance of the envelope and may interfere with the proper adhesion of the fiap.

In some cases the hang-on" may stretch further than as it is illustrated in FIG. 2, and this deleterious feature occurs frequently whether the envelopes are separated from the web 7 by hand or mechanically.

The separation of the assemblies by mechanical means is illustrated in FIGS. 3, 4 and 5 of the drawings where the detacher apparatus, like the one which is the subject of the above mentioned application, is indicated generally by the reference numeral 10. I

One of the side frames upon which the operative parts are supported is shown at 13, and pivotally mounted thereon as at 12 is a tray 11 for collecting the separated envelopes. A stop pin 14 limits the, downward movement of the tray.

The stripper bar or plate 16 is also' pivoted at 12 and is positioned for operation by the stop pin 45. The assembly is threaded into the machine and passes'along a platform 22. The carrier web A is guided around the curved edge 33 of platform 22 and between the pull rolls 3! and 32 while the envelopes are fed, by means not shown but adequately disclosed in the application referred to, onto the stripper plate 16,

whereupon the bonds C are burst and the envelopes are ing to the present invention, an interruption D in the fibrous structure of the web is provided closely adjacent to each of the glue spots C, on the ,upstream" side thereof in relation to the movement of the assembly. These interruptions may take various forms, for example the straight out D in example I of the composite FIG. 6. Or they may be made as a line of perforations as at D in example ll; Circular punched openings D in example III; or a modified figure such as the crescent D in example IV. i

In the case of some web materials, even a deeply scored line may sutfice as a tear interruption.

-It is also understood that the web material may be made of paper stock made more liable to shredding or delaminating than the envelope stock; or contrariwise, inconspicuous slits or fiber interruptions D may be applied to the envelopes themselves adjacent the junction spots C.

feeding the assembly through a business machine. The envelopes B, which together with the web A, form the continuous envelope assembly, are detachably secured to the web by means of the spots of adhesive C, which may be distributed in any desired pattern with respect to the configuration of the envelopes. However, the particular distribution illustrated is a preferred one and confonns generally to those of the above mentioned application and patent, whereby the spots will ultimately be covered by the envelope flaps when the envelopes are sealed.

In FIG. 2, there is illustrated what usually happens when the envelopes are pulled from the web after they are imprinted or otherwise treated. Numerals C and Cindicate the separated portions of the original 'spot C, a portion of the paper of which the web is composed being delaminated and the torn layer C Other modifications in the embodiments illustrated and Iclaim: I

A continuous envelope assembly comprising a carrier web of fibrous material such as paper or the like, and a series of envelopes disposed flatwise along said web and secured thereto, said assembly adapted to be passed through a detacher machine in a given linear direction, the means of tioned immediately to the rear of one of said dots of adhesive as related to such direction of movement, said slits serving to block the continuity of the fibrous structure of the web, so as to provide a stop for any delamination or shredding of the web during passage therethrough the detacher machine.

Claims (1)

1. A continuous envelope assembly comprising a carrier web of fibrous material such as paper or the like, and a series of envelopes disposed flatwise along said web and secured thereto, said assembly adapted to be passed through a detacher machine in a given linear direction, the means of securement being spaced appreciable distances from the leading edges of the successive envelopes considered in said direction of movement, whereby the paths of movement of the web itself and of the successive envelopes may be readily diverged for the purpose of pulling the envelopes from the web, said means of securement comprising small inconspicuous dots of adhesive; and short slits formed in the carrier web and extending transversely of the direction of movement of the assembly through the macHine, each of said slits positioned immediately to the rear of one of said dots of adhesive as related to such direction of movement, said slits serving to block the continuity of the fibrous structure of the web, so as to provide a stop for any delamination or shredding of the web during passage therethrough the detacher machine.
