Device for inverting sheet around transverse axis during promotion between two pressurizing elements of pressurizing machine, has promoter having two grippers circulating around fixed axle

摘要

The device has a promoter (3,4) having two grippers (1,2) circulating around a fixed axle (5), where phase position of grippers is adjustable relative to each other on the length of curve. The forward-moving gripper is formed for acquisition of a sheet (6.1) of a transmission drum (10) at forward-moving edge and the trailing gripper is formed for acquisition of the sheet at the trailing edge.
