An apparatus for producing blanks from a web including a pair of relatively movable upper and lower blades for severing therebetween blanks from a web along a predetermined cut line established by cooperative cutting edges of the blades, an end feed path of travel for the web and a discharge path of travel for the blanks, a mechanism for rotating the blades to selectively vary the cutting angle and thereby vary the sizes, shapes and/or cut line orientation of the blanks severed from the web, a transfer mechanism for transferring each severed blank from a position adjacent the blades and the end feed path of travel to a second position at the blank discharge path of travel, the transfer mechanism including a receiving element pivoted to an arm which in turn is pivoted for movement in a generally horizontal plane, the receiving element be accommodated in a recess adjacent the blades and receiving therein each severed blank for transfer to the discharge path of travel.
Apparatus for producing blanks from a web comprising a pair of relatively movable upper and lower blades for severing therebetween blanks from a web along a predetermined cut line established by cooperative cutting edges of said blades, means for defining a predetermined infeed path of travel for a web at a predetermined selective angle to the predetermined cut line, means for defining a predetermined discharge path of travel for blanks severed by said blades, means for rotating said blades to selectively vary the predetermined selective angle to thereby selectively alter the angular relationship of the predetermined cut line to the web infeed path of travel whereby blanks of varying sizes, shapes and/or cut line orientation can be severed from a web, and means for transferring each blank from a position adjacent said blades after severance to a position more remote from said blades and to said discharge path of travel through an arc of movement corresponding to at least the predetermined selected angle whereby the blanks are continuously moved to congruent positions of delivery along said discharge path of travel.
