    • A machine for bonding layers in a film includes first pay-off unit to unwind a first layer of the film, a second pay-off unit to unwind a second layer of the film, a third pay-off unit to unwind a third layer of the film, a bonding zone to join the various layers of film together, and a winding unit including a reel onto which the bonded film is wound, the bonding zone including at least one bonding unit, the pressing roller being fitted with at least an hydraulic actuator which brings it in contact with the layers of film on the bonding calender, the presser roller and the hydraulic actuator being mounted on a nip rotating around the axis of the bonding calendar so as to vary the position of the point of contact between the presser roller and the calender and hence to vary the breadth of the contact arc, along the surface of the calender, in which the layers are overlapped.
    • 用于粘合薄膜中的层的机器包括:第一释放单元,用于退绕薄膜的第一层;第二放出单元,用于展开薄膜的第二层;第三分发单元,用于展开第三层 所述胶片,将所述胶片各层连接在一起的粘合区,以及卷绕单元,所述卷绕单元包括卷绕所述粘合膜的卷轴,所述粘合区包括至少一个粘合单元,所述加压辊至少装配有液压 致动器,其使其与粘合砑光机上的膜层接触,压辊和液压致动器安装在围绕接合砑光机的轴线旋转的辊隙上,以便改变压紧件之间的接触点的位置 辊和压延机,因此沿着压延机的表面改变接触弧的宽度,其中层被重叠。
