A band of mouldable material (t) from an extruder (2), having the width of the mud-guard or fender to be manufactured, is directed, at a suitable molding temperature, onto a rotating bending drum (5). The band of material moves, pulled by the bending drum (5), under tension, in close contact with the surface of the drum. The tension being produced by means of a velocity difference between the bending drum (5) and the band of material (1) and by means of friction produced by a pressing wheel (7). The cutting member (6) cuts a desired length of the bent band of material travelling on the drum. <IMAGE> |
