Apparatus for shingling sheets in a stack.

摘要

The stack (10) to be shingled is positioned and held conforming about a high friction roller (14) by an endless pressure belt (20) mounted on two spaced idle pulleys (22, 24) and a tensioning pulley (34). Rotation of roller (14) while stack (10) is so held drives stack (10) from support (6) to support (8) and produces equal edge separation of the sheets in stack (10).
