Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling. The selected knife/anvil spacing is readily reproducable for future runs with the same operating conditions.

Abstract: A method and apparatus for formation of a preformed bonded pull tab over a reseal liner is disclosed. The pull tab seal layer of material is bonded together with a reseal liner layer of material for insertion into a closure. The pull tab on the pull tab liner seal is formed prior to combination of the two layers and is folded backwards between the two layers of material.
