ABSTRACT:
Cutting apparatus for cutting moving sheets or webs. A rotatable cutter carrier and a rotatable backup member are respectively provided with cutter blades and grooves, which cooperate in the plane of the sheet and are moved by planetary gear trains through cutting positions wherein cutter blades and backup bars are moved into face-to-face relationship to effect cuts in sheet material that passes therebetween. The gear trains include a stationary sun gear, and idler gears that are rotatably carried in carrier discs and that mesh with the sun gear and with planet gears that are non-rotatably connected to respective ones of cutter bars that carry the cutter blades and to cooperating backup bars. One of the cutter bars or the backup bars is provided with extensible needles for piercing a portion of the sheet section that is intended to be removed therefrom. Holders for the needles are provided with cam followers that engage with a rotatable cam to cause the needles to be extended and to engage the sheet section intended to be removed.
