Abstract
Method and apparatus for slitting rolled material. The material is mounted adjacent to a slitting means which is oscillated substantially tangential to the surface of the rolled material being slit to improve the slitting action. Radially adjustable clamping jaws engage the outer surface of the rolled material, the adjustment of which is controlled by endless chains. A radially expandable supporting shaft is included for engagement with the inner surface of the rolled material for securely mounting that material.
Claims12
In apparatus for slitting rolled material including means for slitting the material and mounting means for mounting the material adjacent to the slitting means, said mounting means including clamping jaws adjustable radially with respect to the longitudinal axis of said rolled material for engagement with the outer surface of said rolled material, the improvement comprising chain means coupled to said clamping jaws for causing radial movement of said clamping jaws.
In a device for clamping rolls of material for working on a cutting or winding machine or the like, including a clamping chuck having a disk as a part thereof, the improvement comprising an endless reversible chain mounted on said disk, drive means for driving said chain, and jaw-supporting sliders mounted in radial guide slots in said disk and coupled to said chain.
A device according to claim 9, 14 or 15, including a clamping shaft having a clamping unit, and in which said drive means also actuates said clamping unit.
