Abstract
The invention is a multipart continuous form having several plies and a means to securely fasten the plies which prevents longitudinal slippage. To achieve this result the form has a series of locking and connecting tabs cut along its edge. The locking tabs fasten the inner plies of the form to the connecting tab, thereby preventing longitudinal shifting.
Claims5
A multilayer continuous form comprising:
- a first outer ply formed from a continuous web;
- a plurality of inner plies consisting of continuous webs all located in vertical alignment with said first outer ply;
- a second outer ply formed from a continuous web and located in vertical alignment with said inner plies and oppositely placed from said first outer ply;
- a plurality of locking tabs cut near the edge of each of said inner plies, located such that said locking tabs run in a row and are in vertical alignment, and such that said locking tabs can be flapped open exposing an opening of like dimension;
- an adhesive strip running along the inner side of said first outer ply and in alignment with said locking tabs;
- and,
- a plurality of connecting tabs cut near the edge of said second outer ply, being like dimensioned and vertically aligned with said locking tabs and oriented such that the forward edges of said connecting tabs point in the opposite direction to the forward edges of said locking tabs, said connecting tabs inserted through said locking tab openings, the ends of said locking tabs locking said connecting tabs in place, each said locking tab coplanar with its respective inner ply, the end of each said connecting tab being bent to be coplanar with said first outer ply and being affixed to the bottom of said first outer ply by means of said adhesive strip, assuring that said first outer ply, second outer ply, and inner plies are held in secure alignment.

- a first outer ply formed from a continuous web;
- a plurality of inner plies consisting of continuous webs all located in vertical alignment with said first outer plies;
- a second outer ply formed from a continuous web and located in vertical alignment with said inner plies and oppositely placed from said first outer ply;
- a plurality of locking tabs which are rectangular flaps cut from said inner plies on three connecting sides so as to allow said locking tab to move in a hinge like manner with respect to the uncut side and located such that said locking tabs run in a row and are in vertical alignment and said locking tabs can be flapped open exposing an opening of like dimension;
- a strip of glue running along the inner side of said outer ply and in alignment with said locking tabs;
- and,
- a plurality of connecting tabs which are rectangular flaps cut from said second outer plies on three connecting sides so as to allow each said connecting tab to move in a hinge like manner with respect to the uncut side, said connecting tabs being like dimensioned and vertically aligned with said locking tabs and oriented such that the forward edges of said connecting tabs point in the opposite direction to the forward edges of said locking tabs, said connecting tabs being inserted through said locking tab openings, the ends of said locking tabs locking said connecting tabs in place, each said locking tab coplanar with its respective inner ply, the ends of said connecting tabs being bent back to lie coplanar with said first outer ply and being affixed to the bottom of said first outer ply by means of said strip of glue, assuring that said first outer ply, second outer ply, and inner plies are held in secure alignment.
