Abstract
A method and apparatus for mounting a supply roll to a rotatable support shaft in an imaging system. The apparatus includes a first collet/collar assembly for accurately positioning the supply roll at a desired location on the support shaft, and a second collet/collar assembly for frictionally coupling the support shaft to an interior surface of a supply core of the supply roll using a deformable gland.
Claims10
An apparatus for mounting a supply roll to a rotatable support shaft, comprising:
- a first assembly for positioning a first end of the supply roll at a predetermined location on the support shaft the first assembly including a collet and a collar for compressing the collet against the support shaft;
- and
- a second assembly for frictionally coupling the support shaft to an interior surface of a supply core of the supply roll, the second assembly including a collet having a deformable gland, and a collar having a surface for compressing the deformable gland against a portion of the collet of the second assembly in response to attachment of the collar to the collet and for causing a surface of the deformable gland to expand in an outward direction against the interior surface of the supply core, wherein the collets further include a plurality of spring members including an inner bearing surface for releasably engaging a surface of the support shaft.
An apparatus for mounting a supply roll having a core with an interior surface, to a rotatable support shaft, comprising:
- an assembly for frictionally coupling a support shaft to an interior surface of a supply roll, the assembly including a collet having a deformable gland, first and second rigid members attached to opposing sides of the deformable gland, and a collar having a surface for compressing the deformable gland against a portion of the collet in response to attachment of the collar to the collet and for causing a surface of the deformable gland to expand outward against the interior surface of the supply roll core in response to attachment of the collar to the collet.
