Process for fabricating weatherseals

Abstract From the Canadian patent

A process for forming linear, thermoplastic weatherseals into a bend position is provided which avoids buckling of the thinner surfaces of the weatherseal material. The process involves the use of a support insert which supports the thinner surfaces during the bending operation and thus assists in preventing , the deformation of the thinner weatherseal surfaces. The support is preferably constructed of a material which is unaffected by temperatures higher than the heat-deformation temperature used to set the weatherseal material into a bent configuration, and thus, the support insert retains its linear shape when removed from the bending press, and therefore can be reused.
