Abstract: A device for sealing a gap between two members. The device comprises at least one elastically expanding hose accommodated in a groove (2) in the wall of the gap. The hose can be expanded by a compressible fluid introduced through a rigid opening such that the hose cannot be displaced in relation to the opening. To provide a device that is easy to install and remove and that requires no straps to secure it, the hose (1) is inserted into the opening (3) and has one end loose and the other end secured by supports.

Abstract: A thermoforming tool employed for wrap-around lamination of a sheet to at least one edge (3) of a molding (2) loosely resting on the tool's lower half. The tool comprises a sheet-stretching frame (4) that is positioned over the molding and lowers a thermally plasticized sheet (5) tensioned therein at its edges into a holding position below the edge of the molding, a device for sealing the sheet off from the lower half of the tool, and a device for applying a suction in the subsequent lamination process. The suction device includes an evacuatable depression (9) in the lower half of the tool and below the edge of the molding. The object is to provide smoother lamination. The lower half (1) of the tool has a sealing lip (8) at the level of a conceptual plane below the edge of the molding. The lip parallels the edge of the molding and demarcates the depression.
