摘要： In a photographic film or paper web handling system, a vacuum drum carried by a moveable carriage automatically picks up the end of a web roll and feeds it to a web path. The location of the roll surface is sensed and the carriage is positioned in close proximity to the roll surface. The pickup of the web end by the vacuum drum is sensed and the carriage is moved from the web roll to a position adjacent the web path. An air chute is provided for transporting the web along the film path to a web perforator. A drive for the web roll is placed in a constant torque mode for maintaining web tension during initial threading and a loop position servo controlled mode for maintaining a loop height in a slack box after threading.

摘要： An apparatus and method are provided for removing a very open shell (28) from a forming mandrel (76), the mandrel being configured so that when the shell is released from the mandrel, the shell springs to an open form. The apparatus includes a fixture (44) for receiving the shell from the mandrel after the shell has been formed and clamped in place, the fixture comprising a pair of spaced claw elements (308,310) having aligned openings (426) through which the mandrel and the shell can pass with the shell formed and clamped in place on the mandrel, the openings being sized to hold the shell in its open form due to the spring force of the shell, and a support (394) connected between the claw elements for maintaining the alignment of the openings. A universal mount (394,424) for the fixture enables it to be positioned accurately to receive the shell from the mandrel.
摘要翻译：提供了一种用于从成形心轴（76）去除非常开放的壳体（28）的装置和方法，所述心轴构造成使得当壳体从心轴释放时，壳体弹簧成打开形式。该装置包括固定装置（44），用于在外壳已经形成并夹紧就位之后从心轴接收外壳，固定装置包括一对间隔开的爪元件（308,310），其具有对准的开口（426），心轴和壳体可以通过形成并夹在心轴上的适当位置的壳体通过，开口的尺寸被设计成由于壳体的弹簧力将壳体保持在其开放形式，以及连接在爪元件之间的支撑件（394），用于保持开口对齐。用于固定装置的通用安装座（394,424）使其能够精确定位，以从心轴接收壳体。
