Abstract:
1. A sheet bending device comprising: a support member; a sheet shaping rail comprising a stationary shaping rail portion securely mounted on the support member and an articulating shaping rail portion pivotally mounted on the support member, wherein the stationary shaping rail portion has a first leg, a second leg and a middle leg, the legs connected to one another to provide the stationary shaping rail portion with a generally U-shaped configuration, and the articulating shaping rail shaping portion is pivotally mounted on the support member with one end of the articulating shaping rail portion adjacent an end of the first leg of the stationary shaping rail portion and an opposite end of the articulating shaping rail portion adjacent an end of the second leg of the stationary shaping rail portion, wherein moving the articulating shaping rail portion from a non-shaping position to a shaping position moves the articulating shaping rail portion toward the middle leg of the stationary shaping rail portion; a force biasing member operatively connected to the articulating shaping rail portion to move the articulating shaping rail portion from the non-shaping position to the shaping position, and a retention member to limit movement of a sheet to be shaped relative to the stationary shaping rail portion wherein the retention member comprises at least one stop member having a cone shaped segment and a cylindrical shaped segment, wherein the cone shaped segment engages a peripheral edge of the sheet to be shaped when the sheet to be shaped is positioned on the stationary shaping member, and the cylindrical shaped segment of the retaining member engages the peripheral edge of the sheet to be shaped to limit movement of the sheet to be shaped over the stationary shaping rail portion toward the middle leg of the stationary shaping rail portion as the articulating shaping rail portion moves from the non-shaping position to the shaping position.
