MATERIAL HANDLING APPARATUS

摘要

A turnover apparatus for inverting a first sheet and placing it horizontally upon a second sheet as said sheets are carried along a horizontal path. The apparatus includes lifting arms for raising the leading edge of the first sheet about its trailing edge and lowering arms for receiving the leading edge of the lifted sheet from the lifting arms and lowering the sheet when the same reaches a substantially vertical position. The transfer of the sheet from the lifting arms to the lowering arms is responsive to the position of either of the arms when handling relatively wide sheets or to the vertical disposition of said sheet when handling relatively narrow sheets.
