ABSTRACT:
An arrangement for transmitting force in a predetermined direction from a sheet of weldable polymer material to a supporting surface, especially for fastening the sheet to the supporting surface. A fastening element anchored in the supporting surface extends through an orifice in the sheet and carries, on the side of the sheet facing away from the surface, a batten which extends parallel to the sheet transversely to the predetermined force direction. The batten is surrounded by an enveloping body which has been applied in molten form and is welded to the sheet.
