摘要： A film cutter adapted to sever individual customer orders of varying film types, i.e., different width and perforation spacing, from a continuous film roll into a number of segments. Each film type has regularly spaced perforations of a particular pitch along one edge thereof. Depending upon the mode of operation (whether the splice frame leads the individual customer orders or trails the orders) the perforations may enter the cutter on alternate sides. A plurality of pin arrangements, one for each operational mode and film type, are provided to lock the film in position and initiate cutting. Depending upon the location of the film perforations and the widths of the film, a proper pin arrangement is selected. At the time at which it is desired to make a cut in the film, the selected pin arrangement is caused to engage the film for insertion within the next following perforation. The insertion of the pin will activate switches which stop the film drive and actuate the film cut-off knife to accomplish the desired film cutting.
摘要翻译：一种胶片切割器，其适于将不同胶片类型的单个客户订单（即，不同的宽度和穿孔间隔）从连续胶片卷切割成多个片段。每种胶片类型沿其一个边缘具有特定间距的规则间隔的穿孔。根据操作模式（接头框架是否引导单个客户订单或跟踪订单），穿孔可能在另一侧进入切割机。提供多个针布置，每个针对每种操作模式和胶片类型，以将胶片锁定就位并开始切割。取决于胶片穿孔的位置和胶片的宽度，选择适当的销排列。在期望在胶片上切割的时候，使所选择的销排列与下一个穿孔中的胶片接合以插入。引脚的插入将激活开关，其停止胶片驱动并致动胶片切割刀以完成所需的胶片切割。
