ABSTRACT:
The illustrated apparatus forms a flange at the front or rear end of a bicycle fender, the end of the fender being generally arcuate as viewed in side elevation. The fender is supported on a shoe member having an arcuate end face with a portion of the fender projecting beyond such end face. A forming member of arcuate curvature is mounted for arcuate movement on an axis concentric with the common axis of curvature of the end of the support block and the arcuate forming member. The forming member has an inverted U-shaped forming edge which passes arcuately downwardly across the projecting end of the fender to cooperate with the end face of the support block to flange the projecting end of the fender downwardly.
