Print roll and mounting means

Claim 1

In combination a shaft, a plurality of axially-aligned printing rolls having bores and being axially mounted on the shaft, and a plurality of collets for locking both ends of each roll to the shaft with the inner end of each roll in tight abutment with the end of the adjacent roll; the ends of each bore being tapered outwardly at an angle to the bore axis to form a collet seat; a collet in each collet seat with the shaft passing therethrough, and each collet being provided with an outer wall portion tapered at an angle matching the angle of the collet seat; the inner collets in the collet seats at abutting ends of said rolls being positioned within said seats to provide a space between the faces of said inner collets; resiliently deformable means in said space for applying axially-directed force against the inner collets when the deformable means is deformed; and means cooperating with said shaft at the outer ends of the plurality of rolls for applying axially directed force against the outer collets in the collet seats in the non-abutting roll ends thereby simultaneously to deform said deformable means to lock to the shaft said inner collets and also said outer collets.
