ABSTRACT:
Apparatus for forming and trimming articles from a web, featuring two conveyors, the first conveyor moving the web through the forming press and into a trimming station, the second conveyor moving the web within the trimming station. The two conveyors move in unison to transport a newly-formed section of web into the trimming station; a shear located between the conveyors severs the web; and, without loss of registration, the second conveyor moves the severed section of web past a trimming die, which cuts articles from a fraction of the severed section during each cycle.
