Method and apparatus for wrapping a stack with a wrapping sheet

摘要

A method and an apparatus for wrapping a stack (12, 13) of superposed sheets, brochures and/or folders with a wrapping sheet (15). The stack (13) is travelling in a first direction (4) on a first conveyor (2) defining a conveying path. A supply of wrapping sheets (14) is placed in line with the first conveyor (2). At the downstream end of the first conveyor (2) a rotating waver wheel (10) is arranged. This waver wheel pulls a top sheet (15) from the supply of wrapping sheets (14) and turns the wrapping sheet (15). Downstream of the first conveyor (2) a second conveyor (3) is provided defining a gap (5) between the first and second conveyors in which the wrapping sheet is inserted. As the stack (13) engages the wrapping sheet (15), the rotating waver wheel (10) folds the sheet around the stack.
