ABSTRACT:
The present invention relates to a transport roller consisting of elastic material with a rotation shaft of nonelastic material located in a central cavity. In order to optimize the functional properties such as degree of elasticity, resistance to wear and mechanical load-bearing capacity, the roller body (1), which consists of open-cell foam, is closed on its surface by a skin (2) of resilient material which forms an outer surface of the roller and anchors itself by engagement in the foam pores (7).
