    摘要： A system of incrementally moving a foil, or other flexible and elastic elongated web, through a work station, by contacting and registering the foil on both sides of the work station. An example of such a work station is a hot stamping press that transfers optical images from the foil to other substrates. A drive mechanism, with an associated foil registration device, is provided at each of the entrance to the work station and the exit from it. Each registration device optically detects registration marks provided on the foil along its length, and is used to stop its associated drive mechanism after a predetermined number of marks have passed. This dual drive system maintains registration of the foil or other web throughout an extended work station. It is particularly advantageous for use with those hot stamping presses that either have a large number of die or whose multiple die are widely separated, since the multiple images carried along the foil are then all properly registered with the die.

    摘要： An improved thermoplastic molded part is disclosed including a stress reducing juncture which is operative to reduce the differential shrinkage of the molded plastic, which would otherwise develop due to the uneven cooling of the plastic to room temperature, thereby inhibiting the warping of the part. More specifically, an improved thermoplastic molded part is provided including at least one wall member formed unitary with another structural element such as another wall, flange or boss area. The thermoplastic part is further provided with a stress reducing juncture, defined by an elongated trough-like recess, located in the wall member adjacent the other structural element. Preferably, the recess has a width approximately equal to the width of the wall member and a depth equal to approximately one half that width. The recess functions to decrease internal stresses that normally develop due to differential shrinkage of the molded plastic during cooling to room temperature. By reducing internal stresses, the unwanted warping of the part is minimized.
