US3980207A Pinch rollers (8 Track Cartridges)

Abstract Patent US3980207A

Disclosed is a pinch roller for use in continuous magnetic tape cartridges. In one preferred embodiment, the pinch roller has an inner and out cylindrically shaped wall interconnected by a plurality of flexible U-shaped webs. Each wall has a flange extending radially from the mid-point of the axial length of the roller. These flanges are interconnected by U-shaped webs. The U-shaped webs extend above and below the mid-point in alternate and adjoining relationship so that the outer wall of the roller can move to an eccentric position with respect to the inner wall and/or permit the outer wall to align itself with the capstan should the cartridge be disposed with the principal axis of the roller at an angle to the capstan.
