A method and apparatus for reducing friction in a cam buckle for tightening a strap. The cam buckle includes a frame, a brake member (120), a roller member (150), a biasing element (134) and a webbed strap. The brake member includes a serrated surface (126) and is rotatably coupled to the frame and pivotal about a first axis (130). The roller member (150) is rotatably coupled to the frame about a second axis (152), wherein the first axis and the second axis are substantially parallel to each other. The biasing element (134) is operable to bias the serrated surface (126) of the brake member (120) toward the roller member (150). The webbed strap is formed from a polymeric material and is operable to be biased between the serrated surface (126) and the roller member (150) so that the brake member (120) biases the webbed strap against the roller member (150). |
