TRANSFER DEVICE FOR OFFSET PRINTING
Document Type and Number:
WIPO Patent Application WO/2010/137315
Kind Code:
A1
Abstract:
A gate-shaped frame (21) is provided to cross over a guide rail (13) provided on a mount (12). Right and left bearing housings (28a, 28b) which rotatably hold a rotational shaft (30) of a blanket roll (19) at a roll support frame (27) are attached to columns (23a, 23b, 23c, 23d) of the frame (21) through linear motion guides moving in the vertical direction, and further, nuts (36) of ball screw mechanisms (33) are attached to respective bearing housings (28a, 28b), so as to form a transfer device (18) for offset printing. At the time of performing transferring or retransferring by pressing the blanket roll (19) from above a plate (14) on a plate table (15) or a print target (16) on a print target table (17) moving on the guide rail (13), with a predetermined contact pressure, deformation of mechanical structure portions other than the blanket roll (19) caused by the reaction force of the contact pressure can be prevented.
