ABSTRACT:
An insulator element (10), especially destined for noise insulation in vehicles, comprises an adhesive layer which is covered by a removable protective element (12). To facilitate removal of the protective element by peeling, the outer contour of the protective element (12) projects beyond the outer contour (11) of the insulator element (10). In forming a peeling tongue (13), first a protective element layer is removed from an adhesive layer of the starting material and swung into an upright position or bent back. During the subsequent cutting or punching process to produce the insulator element (10), the area of the protective element layer which was folded back is affected in part only, thus providing the peeling tongue (13). Thereafter the hinged peeling tongue (13) is bent so as to project beyond the outer contour (11) of the insulator element (10) thus offering a big enough gripping area to peel off the protective element (12).
