Abstract: A hot-welding process which makes it possible to obtain a weld of any desired depth in each zone of the welded elements. The strip used consists of at least two superimposed thicknesses, one made of a hot-welding material having a fusion temperature of the same order as that of the film, and the other being made of a support material having a higher fusion temperature. The process comprises the steps of heating a section of the strip to a temperature between the fusion temperature of the hot-welding material of which it is made and that of the support material, transferring this section to the film, applying the fusion face of the strip to the film, and simultaneously producing differential cooling of the materials. These operations are then reproduced on an adjacent section of the strip, until the latter has been welded along its entire length.

Abstract: The disclosure herein describes a positioning device for at least one edge of a flexible film intended to travel continuously under the action of driving means in order to be subjected to a pre-determined operation. Two adjacent guiding elements include two oppositely facing surfaces spaced apart by a distance slightly greater than the thickness of the film; abutment means are provided with a positioning edge parallel to the direction of movement of the film. At least one pair of rollers are arranged symmetrically on each side of the guiding elements and are each provided with a flexible rolling skirt between which the film edge is elastically gripped; the plane of rotation of the skirts is slightly oblique with respect to the positioning edge so that the skirts of the rollers apply to the film forces directed towards the positioning edge, tending to apply the edge of the film against the positioning edge.

Abstract translation: 本文的公开内容描述了一种用于柔性膜的至少一个边缘的定位装置，其旨在在驱动装置的作用下连续地行进，以便经受预定的操作。 两个相邻的引导元件包括两个相对的表面，间隔开比稍大于膜厚度的距离; 邻接装置设置有平行于膜的运动方向的定位边缘。 至少一对辊对称地布置在导向元件的每一侧上，并且各自设置有柔性的滚动裙部，薄膜边缘弹性地夹在其之间; 裙部的旋转平面相对于定位边缘略微倾斜，使得辊的裙部适用于朝向定位边缘的薄膜力，倾向于将薄膜的边缘施加在定位边缘上。
