Abstract
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.

184 words
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.
