Abstract
Abstract In the continuous feeding from a stack, the entire stack is advanced horizontally without interruption toward a cutter which incessantly slices the material from the leading end of the stack and, at all times as the slice gravitates in a constant flow from the cutter, it is steadily removed at a rate to avoid buildup beneath the cutter, and immediately discharged in a ceaseless stream to a point or area of discharge. In order to effect cutting of the stack throughout its entire transverse crosssectional area from side to side and top to bottom, the cutter is caused to sweep along a polygonal path that corresponds essentially in shape to the transverse, peripheral configuration of the stack. The cut is on an inclined plane and the cutter opens the kerf as it travels in order to deflect the slice away from the stack, all for the purpose of assuring a steady, uniform gravitation of the cutaway material to a lateral conveyor beneath the cutter. The cutter is also rotated continuously while it sweeps through the stack, and is canted to present a leading bite so as to avoid drag on the stack along the trailing portions of the cutter.

Claim 1
Independent Claim
109 words
In a machine for continuously feeding material from a stack thereof: conveyor means underlying the stack for continuously advancing the latter along a substantially horizontal path of travel; a support spaced forwardly of the leading end of said stack; means for rotating said support within an upwardly extending plane; and a cutter rotatably mounted on the support between the latter and said end of the stack for movement of the cutter with the support around the axis of rotation of the support, the axis of rotation of the cutter extending toward said end of the stack and being at an angle to said axis of rotation of the support.
Claim 2
