    • Herein described is a device for sealing and cutting film in packaging systems for loose product, comprising transversal rotating shafts (1, 2) synchronised with each other, to which a couple of pincers (32, 34) is engaged comprising sealing and cutting means (15). Said pincers are connected to mechanisms comprising lower prestretching plates (28) and upper prestretching plates (29) forced in predefined positions by springs (10, 11) that react to a set almost circular path that brings the two pincers into contact one in front of the other so that the upper ones hold back the loose product (101) and the lower ones carry out a prestretching of the film, so as to prepare the film (100) for sealing and cutting without any interpositioning of loose product.
    • 这里描述了一种用于在用于松散产品的包装系统中密封和切割膜的装置,包括彼此同步的横向旋转轴(1,2),一对钳子(32,34)与其啮合,包括密封和切割装置 15)。 所述钳子连接到包括下部预拉伸板(28)和上部预拉伸板(29)的机构,所述上部预拉伸板(29)通过弹簧(10,11)被强制在预定位置,弹簧(10,11)对设定的几乎圆形的路径作出反应,使得两个钳子在 另一个使得上部的部件阻止松散的产品(101),并且下部的部件进行薄膜的预拉伸,以便制备用于密封和切割的薄膜(100),而不会产生松散的产品的插入。
