Appl. No.:

10/329588

Assignee:

Paper Converting Machine Co. - Green Bay WI

International Classification:

B41F 1310

US Classification:

101376, 101375, 101329, 101479, 428 369, 492 38, 492 28, 279 32, 279 5, 279 6

Abstract:

A sleeve is provided with a clamp for removably clamping the sleeve on a mandrel. A rigid ring is mounted inside of the sleeve at each end of the sleeve. Each ring has a generally cylindrical inside surface which includes a curved contact portion which extends for less than 180 degrees and which is engageable with the outside surface of the mandrel. A curved clamp arm is pivotally secured at one end thereof to each ring. An eccentric shaft extends through an opening in the other end of the clamp arm. Rotation of the eccentric shaft moves the clamp arm toward the contact portion of the ring so that the mandrel can be clamped between the clamp arm and the contact portion.

International Classification:

B41F005/00

US Classification:

101216000

Abstract:

This invention uses a combination of a rotor (rotating) component of an electromagnet motor that is integrated as part of a driven rotational load and immersed within an longer stator (stationary) component of the motor allowing for axial motion of the load (rotor) independent of the motor stator and housing. An alternative covered by this disclosure is a rotor that is longer relative to the length of the stator. The directly driven load provides improved rigidity for torque transmission and superior control performance. The axial motion capability lends itself to other functions such as printing sleeve removal for exchange purposes in a flexographic press.
