Title:
【発明の名称】リソグラフ印刷プレート用クランプアセンブリ
Document Type and Number:
Japanese Patent JP2918491
Kind Code:
B2
Abstract:
A clamp assembly for clamping a lithographic plate to a cylinder includes a base defining a channel and a plate mounted to the base and overlying the channel. An elongated cam member is rotatably positioned in the channel, the member having a cam surface profiled so that when the cam member is in a first angular position, that surface extends relatively close to the plate and when the cam member is in a second position, that surface is further away from the plate. Stops are included for establishing the two positions of the cam member. When the cam member is in its second position and an edge margin of a recording medium is inserted between the cam member and the plate, moving the cam member to its first position causes the clamp assembly to simultaneously grip and pull on the recording medium. An interposer may be positioned between the plate and the cam member to prevent direct engagement of the recording medium by the cam member and thus prevent the clamp assembly from pulling on the recording medium while clamping the medium.
