SHEET SHINGLING MACHINE

摘要

A machine for shingling a multiplicity of strips of sheet material so that a narrow portion of each strip below the top one extends beyond the overlying sheets and all the strips are secured together. A frame carries a horizontally extending suction head having slots in the top and having air suction means leading to the slots. Individual plates are moved over the suction head being guided by guides on the frame to move lengthwise of the slots. The plates have rows of apertures extending parallel to the slots. The apertures in each row are spaced apart the distance the strips are to be overlapped. A support for a stack of strips is reciprocated on the frame alongside the suction head but above the plane in which the plates move. A suction device, mounted on the frame moves between a position over the support to pick up a strip from the stack upwardly and to lower it downwardly over the suction head to deliver a sheet on to the plate. A glue depositing device movable with the suction device applies glue spots to each moved strip. Stop means locate the plate for each shingled unit.
