Abstract

A pre-prepared paster pattern designed to effectively create a splice between the first web of a first roll of paper feeding into a high speed printing press and the leading edge of the second web of a second replacement roll of paper. The paster pattern comprises a first extensive paper layer having two generally triangularly shaped portions adapted on a first side to be adhesively connected to the end portion of the replacement roll and to a web portion of the replacement roll spaced from the end portion. An array of pressure sensitive adhesive layers are applied to the second and opposing side of the first paper layer and are adapted to adhere to the first web of the first roll while the first web is being fed into the high speed printing press. A very tacky adhesive layer is applied to the second side at the apex of each triangular portion and is protected by a removable cover or release paper layer. A second extensive cover or release paper layer overlies the first paper layer and is releasably adhered thereto. The second layer is designed to protect the pressure sensitive adhesive on the first layer during non-splicing operations whereby on removal of the second layer, the pressure sensitive adhesive is undamaged and has maximum adhesive properties so as to effect reliable splices between the webs of the rolls.

Dependent claims

A pre-prepared paster pattern (20) designed to effectively create a splice between a first or expiring web (14) of a first roll (12) of paper feeding into a high-speed printing press and an end portion (17) of a second, or new, or replacement web of a second, or new, or replacement roll (16) of paper, comprising

a paster element having at least one base portion (32), each having a length substantially equal to the width of the second, or new, or replacement web,
said paster element having at least one triangular portion, the base portion or portions (32) of the paster element defining the base or bases of the triangle or triangles formed by the triangular portion or portions, and the apex or apeces of the triangular portion or portions being adapted to be removably adhered to a web region of the new, or replacement roll;
a first pressure-sensitive adhesive region (34) located at a first side (29) of said paster element and extending across the length of said paster element, and hence substantially across the width of the second, or new, or replacement web,
said first pressure-sensitive adhesive region being adapted to be adhesively connected to the end portion (17) of the second, or new, or replacement roll (16);
a first release paper layer (38) substantially congruent with, and overlying said first pressure-sensitive adhesive region (34) of said paster element, and releasably adhered thereto;
an array of pressure-sensitive adhesive regions (39, 44, 48, 52, 56) applied to a second side (31), opposite said first side of said first paster element, and adapted to adhere to the first or expiring web (14) of the first roll (12) while the first or expiring web is moving and is being fed into the high-speed printing press,
wherein said array of pressure-sensitive adhesive regions form individual strips of adhesive (39, 44, 48, 52) extending in a longitudinal direction with respect to the first, or expiring web, separated by non-adhesive strip-like engagement areas (42, 46, 50, 54),
said non-adhesive strip-like areas providing engagement areas for rotating means (22) for providing rotation to the replacement roll (16), and which allow for escape of air during the splicing operation, when said first web (14) of the first roll (12) and the end portion (17) of the second web of the replacement roll (16) are pressed together;
and
a second release paper layer means (58, 60, 62, 64, 66) overlying said strips of adhesive of the array of pressure-sensitive adhesive regions,
said first release paper layer (38) and said second release paper layer means being designed to protect the first pressure-sensitive adhesive region (34) and said pressure-sensitive strips of adhesive (39, 44, 48, 52) during non-splicing operations, whereby, on removal of said respective release paper layer, a pressure-sensitive adhesive on said region and on said strips is undamaged and has maximum adhesive properties so as to effect reliable splicing between the webs of the rolls.

A combination of

a new, or replacement, or second roll of paper (16) adapted for splicing to a web (14) of an expiring or first roll (12) of paper being fed at high speed into a high-speed printing press,
said new, or replacement, or second roll (16) of paper including a web having a web end portion (17), said combination further including
a pre-prepared paster pattern (20) comprising
a paster element having at least one base portion (32), each having a length substantially equal to the width of the second, or new, or replacement web,
said paster element having at least one triangular portion, the base portion or portions (32) of the paster element defining the base or bases of the triangle or triangles formed by the triangular portion or portions, and the apex or apeces of the triangular portion or portions being adapted to be removably adhered to a web region of the new, or replacement roll;
a first pressure-sensitive adhesive region (34) located at a first side (29) of said paster element and extending across the length of said paster element, and hence across the width of the second, or new, or replacement web,
said first pressure-sensitive adhesive region being adapted to be adhesively connected to the end portion (17) of the second, or new, or replacement roll (16);
a strip-like array of pressure-sensitive adhesive regions (39, 44, 48, 52, 56) applied to a second and opposing side (31) of said first paper layer and adapted to adhere to the web (14) of the first roll (12) of paper while the first roll of paper is being fed into the high-speed printing press,
non-adhesive strip-like areas (42, 46, 50, 54) between the adhesive strip-like regions of the pressure-sensitive array;
said non-adhesive strip-like areas providing engagement areas for rotating means (22) for providing rotation to the replacement roll (16), and which allow for escape of air during the splicing operation, when said first web (14) of the first roll (12) and the end portion (17) of the second web of the replacement roll (16) are pressed together;
a first release paper layer (38) substantially congruent with and overlying said first pressure-sensitive adhesive region (34) of said paster element and releasably adhered thereto;
and
a second release paper layer (58, 60, 62) covering and protecting said array of pressure-sensitive adhesive regions on said second side during non-splicing operations, whereby, upon removal of said release paper layers, a pressure-sensitive adhesive means on said adhesive regions (39, 44, 48, 52, 56) will be undamaged and have maximum adhesive properties so as to effect reliable splices between said webs of said first and second rolls,
said release paper layers protecting said adhesive means and regions.
