摘要： Rotatable plastic rollers are produced by either injecting between a roller shaft and an outer running roller layer a thermoplastic material which, during cooling down, shrinks toward the roller shaft and away from the outer running roller layer on account of a contraction in volume or, in the multi-component injection-molding process, by first injecting the outer running roller layer and then injecting between the latter and the roller shaft a thermoplastic material which then likewise shrinks toward the roller shaft and away from the outer running roller layer. The process produces plastic rollers comprising an inner running roller layer (2), which is bonded solidly with the roller shaft (1), and an outer running roller layer (3), which can rotate freely with respect to said inner layer by means of a sliding gap (6). The roller shaft may optionally also be sheathed with a thermoplastic elastomer. This may take place in the same process during the multi-component injection molding.
