US 6,655,435 B2 · System for creating linerless pressure sensitive coil of stamps

Abstract

A system for creating a coil of stamps from a web of stamp material having an adhesive applied to a side thereof is provided. The system includes an anvil and a perforation die cooperating therewith with the web passing therebetween in order to perforate the web. The web is passed between the anvil and the die with the adhesive side thereof facing the anvil. The anvil is chilled so as to inhibit the adhesive from adhering thereto as the web is perforated. The anvil may be chilled from an outer surface thereof, or may be hollow and chilled from an inner surface thereof. In the former case, the system preferably includes a trough holding a chilling material through which at least a portion of the outer surface of the anvil is passed. Where the anvil is chilled from an inner surface thereof, a cooling fluid is preferably passed therethrough.

A system for creating a coil of stamps from a web of stamp material having an adhesive applied to a side thereof, said system comprising:

a substantially cylindrical anvil;
a perforation die cooperating with said anvil with the web of stamp material passing therebetween in order to perforate the web of stamp material;
wherein the web of stamp material is passed between said anvil and said perforation die with the side of the web of stamp material having the adhesive applied thereto facing said anvil;
wherein said anvil is chilled so as to inhibit the adhesive applied to the web of stamp material from adhering thereto as the web of stamp material is perforated by cooperation of said perforation die and said;
and
a liner application mechanism for applying a liner material to no more than a portion of the web of stamp material.

A system for creating a coil of stamps from a web of stamp material having an adhesive applied to a side thereof, said system comprising:

a substantially cylindrical anvil;
a perforation die cooperating with said anvil with the web of stamp material passing therebetween in order to perforate the web of stamp material;
wherein the web of stamp material is passed between said anvil and said perforation die with the side of the web of stamp material having the adhesive applied thereto facing said anvil;
wherein said anvil is chilled so as to inhibit the adhesive applied to the web of stamp material from adhering thereto as the web of stamp material is perforated by cooperation of said perforation die and said anvil;
a spool of liner material;
a cutting mechanism for cutting the liner material into a plurality of discrete pieces of liner material having a predetermined length;
an application mechanism for applying the pieces of liner material to the side of the web of stamp material having the adhesive applied thereto;
a bursting blade extending across a width of the web of stamp material, said bursting blade having a narrow tip and being movable substantially perpendicular to the web of stamp material such that when moved fully toward the web of stamp material, said bursting blade breaks a plane formed by the web of stamp material;
and
wherein said bursting blade is moved forcefully toward the web of stamp material adjacent to a perforation in the web of stamp material in order to burst the perforation and separate a coil of stamps from the remainder of the web of stamp material.
