Abstract A printing press especially adapted for printing pressure sensitive adhesive-backed labels, comprising a novel paper feeding mechanism having means for maintaining constant tension including a self-adjusting brake and tension indicating means, a printing press head having two parallel ink feeds to permit the inking roller to move across the printing plate in either direction in order to ink the plate, a novel die-stamp or die-cut mechanism which assures a uniform application of cutting force over the entire peripheral edge of the label by virtue of a slightly resilient platen and a twin link arrangement for moving the movable die up and down, out of and into cutting relation with the label paper, a novel stripper having a slip clutch for driving a drum that pulls the unwanted material from the printed label at a substantially constant tension, a cutter of unique design not employing sheering for cutting the labels into longitudinal strips of a preselected integral number of labels and a takeup mechanism for rolling up the printed labels in lieu of cutting.
A diecutter comprising a stationary slightly deformable platen, a movable platen having a pair of spaced apart sides and including means for removably mounting a die thereon, means for mounting said movable platen for pivotal movement relative to said stationary platen from and to a first position in which said movable platen is in close confronting substantially parallel relation to said stationary platen and to and from a second position in which said movable platen is at an angle to and spaced from said stationary platen, and means for moving said movable platen to and from said first and second positions including a pair of reciprocably movable links, and means for pivotally connecting each of said links to one of said sides.

A diecutter comprising a stationary slightly deformable platen, a movable platen having a pair of spaced apart sides and including means for removably mounting a die thereon, means for mounting said movable platen for pivotal movement relative to said stationary platen from and to a first position in which said movable platen is in close confronting substantially parallel relation to said stationary platen and to and from a second position in which said movable platen is at an angle to and spaced from said stationary platen, and means for moving said movable platen to and from said first and second positions including a pair of reciprocably movable links, and means for pivotally connecting each of said links to one of said sides.
Claim 3
