Abstract

This multiple ply, continuous form permits high speed decollating, separating, and stacking of individual pre cut forms without bursting or cutting. Maximum speed and reliability are realized, using relatively simple equipment. This is because the continuous carbon plies act as continuous chute blades to separate each ply of clean edge sheets or cards.

No Burst Or Cut, Continuous Forms

This multiple ply, continuous form permits high speed decollating, separating, and stacking of individual pre cut forms without bursting or cutting. Maximum speed and reliability are realized, using relatively simple equipment. This is because the continuous carbon plies act as continuous chute blades to separate each ply of clean edge sheets or cards.

The arrangement consists of a standard card 10 backed up with four paper sheets 11, all interleaved with one time carbon webs 12. The carrier strips 13 are virgin kraft, approximately .007 inches thick, and polycoated on the top side only for heat sealing. During assembly, a plurality of straight slits 14 are formed by rotary cutting of the carrier strips to provide individual tab sections 15. These are interleaved in between the card and paper sheets to support them. The standard card sheet 10 and the cutoff sections 11 of preprinted reels of paper forms are individually adhered to the tabs 15 either by heat sealing or by gluing. Continuous reels of one time carbon 12, slightly narrower than the distance between carrier strips and preferably without perforations, are interleaved between all plies. No fastening of the carbon is required. This, together with the one quarter inch spacing between sets, permits zig zag folding with no uneven stacking due to staples or other fastening means.

Disassembly is simply carried out by providing a pair of drive rolls for each carbon ply. Pullin...
