Semiautomatic machine for assembling paper dust jackets on new hard cover books

摘要

This is a machine which assists the operator in assembling paper dust jackets around the hard covers of a new book. The machine includes the plurality of vacuum suction cups mounted on a pair of oscillating transferring arms which transport the paper jacket from a supply stack to position the jacket on the back of a hard cover book while the book is being held in a positioning jig which also supports the covers in substantially horizontal position to receive the jacket from the vacuum cup and transfer arm assembly. The transfer arms are mounted on an oscillating shaft which is actuated by the positive air discharge from a compressor. A vacuum pump provides the vacuum for the suction cups. The chain and sprocket drive rotates the transfer arms and the suction cups from the plane of the pickup position to the plane defined by the book covers in the positioning jig during the transfer movement of the arms through their predetermined arc.
