Abstract
A tape roller has a plastic sleeve which is journalled between bearings formed in opposing walls of a plastic cassette housing. The wall is cored out around at least one of those bearings so that the bearing is supported only by bridges which bow outwardly to receive an oversize sleeve. Preferably there are two such bridges at the bearing, the thicknesses of which are about 20% that of the wall.
