Abstract:
1. A stacking system for stacking a plurality of sheets of material that are fed into the system in a linear feed, comprising: a first feed surface capable of supporting the plurality of sheets, the first feed surface moving at a first speed; a pulley connected to a support and disposed above the first feed surface, wherein the pulley is capable of moving in the direction of a feed to create a gap in the feed wherein the pulley has a first condition in which the pulley is stationary and the plurality of sheets passes beneath the pulley and a second condition in which the pulley moves in the feed direction at the same speed as the first speed of the first feed surface; a second feed surface capable of supporting the plurality of sheets, wherein the second feed surface has a first condition in which it moves at a speed equal to the first speed of the first feed surface, and a second condition in which the second feed surface moves at a second speed that is faster than the speed of the first feed surface to separate the plurality of sheets into a first portion and a second portion; a first set of blades that can move in a first direction; a second set of blades that can move in a second direction that is different from the first, wherein the first and second set of blades are interleaved in an extended position of the first set of blades and a up position of the second set of blades.
