Abstract
The invention encompasses multiple-ply carbonless paper rolls having the plies adhesively joined along at least one edge of the roll. Advantageously, the individual plies remain adhered together when the plies are unwound and separated from the main roll but are still relatively easy to separate from each other.
Claims22
A roll of overlapping wound plies capable of being separated into a plurality of imprintable forms, each said form being adapted to be removed from said roll, said roll comprising:
- (a) a top ply and a bottom ply, each of said plies defining at least one longitudinal edge in register with a corresponding longitudinal edge of another ply;
- (b) said top ply being disposed over and in register with said bottom ply and at least one surface of said top and bottom plies being coated with a carbonless image producing agent;
- (c) optionally, one or more intermediate plies disposed between and in register with said top and bottom plies along a longitudinal edge defined by each said intermediate ply, each of said top, bottom and any intermediate plies defining respective upper and lower surfaces, said plies in combination being capable of transferring an image from at least one of said ply surfaces on one ply to at least one surface of another ply;
- and
- (d) adhering means applied to said roll along at least said registered longitudinal edge of said wound plies for adhering said plies to one another and for permitting said plies to be releasably separable from said roll and from each other.
A method of maintaining a roll of overlapping wound plies in register with each other to permit said registered plies to be unwound from said roll and separated into a plurality of imprintable forms wherein each form comprises a top ply, a bottom ply, said top and bottom plies each having at least one surface coated with a carbonless image producing agent, and, optionally, one or more intermediate plies, said intermediate plies being free of a recess;
- each of said plies defining at least one longitudinal edge in register with a corresponding longitudinal edge of another ply, said top ply being disposed over and in register with said bottom ply, and said overlapped, registered longitudinal ply edges forming one side of said roll when said plies are overlapped and wound together,
- said method comprising the step of applying adhering means to one side of said registered plies, including said top and bottom plies, while said plies are wound in a roll whereby said adhering means adheres a wound ply to an adjacent wound ply along at least said registered ply edges.
A roll comprising at least one imprintable form, each said form comprising:
- (a) a top ply and a bottom ply, each of said top and bottom plies defining at least one longitudinal edge in register with a corresponding longitudinal edge of the other top or bottom ply, said top ply being disposed over said bottom ply, and each of said top and bottom plies defining respective upper and lower surfaces;
- (b) said top ply lower surface and said bottom ply upper surface being coated with a carbonless image producing agent;
- (c) at least one of said top ply upper and said bottom ply lower surfaces being free of carbonless image producing agent;
- (d) optionally, one or more intermediate plies disposed between and in register with said top and bottom plies, each said intermediate ply defining a longitudinal edge in register with the corresponding longitudinal edges of said top and bottom plies and further defining an upper surface and a lower surface coated with a carbonless image producing agent;
- (e) means for releasably adhering said lower coated surface of said top and any intermediate plies to an adjacent upper coated surface of said bottom ply and any intermediate ply along at least said longitudinal edges of said plies without adhering a coated surface to an adjacent surface free of carbonless image producing agents;
- and
- (f) wherein each said coated surface is releasably adhered to an adjacent coated surface along at least one of said longitudinal edges without adhering a coated surface to an adjacent surface free of carbonless image producing agent;
- whereby said form having said releasably joined plies can be unwound and removed from said roll free of adhering to said remaining portion of said roll.
