Japanese Patent JP2020131554
Kind Code:
A
Abstract:
To provide a sheet delivery mechanism capable of preventing pressure variation due to contact between an impression cylinder and a transfer cylinder in a sheet-fed printer, in particular, of preventing heat expansion and bound of a wiping roller in an intaglio printing machine and a transfer roller in an offset-printing machine, as well as, of preventing the roller from biting into the transfer cylinder so as to stabilize printing quality.SOLUTION: A sheet delivery mechanism comprises: at least a pair of gripper mechanisms disposed perpendicularly to a cylinder axis of an impression cylinder in a sheet-fed printer and at both corners of a peripheral surface of the impression cylinder; or at least a pair of sheet-feeding suckers embedded in the peripheral surface of the impression cylinder in parallel to the cylinder axis of the impression cylinder.SELECTED DRAWING: Figure 1
