    • Method for the production of a compound foil as an endless strip, the compound foil to be processed in the form of rectangular blanks covering a width of the endless strip characterized in that two different foil strips, of which a first strip contains an aluminum foil (4) or a paper are drawn through a lamination machine with tractive forces to overcome friction losses in the machine, these tractive forces producing different elongations in said two different foil strips, that one of the endless strips is provided at one side surface with a binding agent over a connecting surface, which consists of several partial areas (3, 13) separated from each other, that the two strips are connected to each other while the both strips being elastically stretched to different elongations as the strips are drawn through the lamination machine whereby after the two foil strips coming back again to their non-stretched starting state, that surfaces of the blanks each have one central area and two margin areas (9, 12) bordering on two blanks surface margins extending both in the endless strip extension, with, in each instance, in those margin areas (9, 12 ) a first proportion defined by the connecting surface area divided by the margin area surface being significantly greater than a second proportion defined by the connecting surface at the central area divided by the central area surface and that in the margin areas (9, 12) of the blank surface the said first proportion is at most 75%.
    • 用于生产作为环形带的复合箔的方法,待处理的复合箔以覆盖环形带的宽度的矩形坯料的形式,其特征在于两个不同的箔带,其中第一条带包含铝箔( 4)或纸通过具有牵引力的层压机被拉伸以克服机器中的摩擦损失,这些牵引力在所述两个不同的箔条中产生不同的伸长率,其中一个环形带在一个侧表面处被提供结合 在由连接表面分离的几个部分区域(3,13)组成的连接表面上,两个条带彼此连接,同时两条条被弹性地拉伸到不同的伸长率,因为条被拉过层压机 由此在两条箔带再次回到其未拉伸起始状态之后,坯料的各个表面各自具有一个中心区域和两个边缘 在两个空白区域上接合的区域(9,12)中,两个坯料的表面边缘在环形带延伸部中延伸,在每个情况下,在这些边缘区域(9,12)中,由连接表面积划分的第一比例除以边缘区域 表面明显大于在由中心区域划分的中心区域处的连接表面和空白表面的边缘区域(9,12)中限定的第二比例,所述第一比例至多为75%。
