【発明の名称】輪転印刷機の胴へ胴張りを固定するための締付け装置
Document Type and Number:
Japanese Patent JP2705941
Kind Code:
B2
Abstract:
To permit uniformly tensioning a holding strip (11) in which end portions (22, 23) of a cover layer such as a rubber blanket (24) can be inserted, the strip (11) is coupled to a plurality of rods (9) extending radially inwardly, and uniformly distributed over the axial length of the strip (11), the rods (9) being coupled to respective pistons (5) slidable in cylinder bores (4) worked in the bottom of the groove (2). Hydraulic or pneumatic pressure can be applied to one face of the piston, the opposite face of the piston being loaded by a spring (17). Thus, since the pressure being applied to all the pistons will be uniform, tensioning pressure (FIG. 2) will be uniform, or raising pressure (FIG. 3) will be uniform. Rather than using fluid pressure, other non-mechanical energy, such as electrical energy, can be used to raise the strip (11) by electromagnetic coupling of solenoids to the rods (9).
