    摘要： A device for the delivery, one by one, of rectangular pieces of film from a stack, the stack being incorporated in a storage magazine with a substantially flat pressure plate keeping the stack by spring pressure against retaining members acting upon the top film, at least one of the retaining members being a pressure member that can move to and fro near one side of the stack, which pressure member can push one edge of the top film toward the opposite edge, as a result of which the top film is released from the stack over a large part of its surface. The invention being that the direction of active movement of the pressure member coincides with the direction in which the films are delivered, that near the delivery end of the magazine a blocking device is provided which can be moved into the path of the top film, causing it to bulge during the active movement of the pressure member, and that furthermore a second blocking device is provided which, near the end of the active movement of the pressure member, is pressed behind the pushed-up edge of the top film of the stack, and presses it back, counter to the spring force acting upon, to such an extent that the top film is released from the retaining members and after removal of the first blocking device, can extend freely in one direction of delivery.

    摘要翻译： 一种用于从堆叠中逐个传送矩形片的片的装置，所述堆叠被结合在具有基本上平坦的压力板的存储盒中，所述压板通过弹簧压力抵抗作用在顶部膜上的保持构件至少保持 保持构件中的一个是可以在堆叠的一侧附近移动的压力构件，该压力构件可以将顶膜的一个边缘朝向相对的边缘推动，由此顶部膜从 堆叠在其大部分表面上。 本发明是压力构件的主动运动方向与胶片输送方向一致，在胶囊的输送端附近设有一个阻挡装置，该阻挡装置可以移动到顶膜的路径中，导致 其在压力构件的主动运动期间膨胀，并且还提供了第二阻塞装置，其在压力构件的主动运动的结束附近被压在堆叠的顶部膜的上推边缘的后面 并且抵抗作用在其上的弹簧力，使顶膜从保持构件释放并且在移除第一阻挡装置之后可以在一个输送方向上自由延伸。
