An apparatus is disclosed for tucking in and glueing over the edge zones of a supporting material to be provided on one side with a surface covering. The supporting material comprises mouldings which are usually of a fairly complicated spatial design, and the apparatus is so designed as to imitate as true to nature as possible the manual method of tucking in and glueing over the covering overlap around the edge of the moulding by the thumb and other parts of the human hand, which has hitherto given the best results. Members to be moved for this purpose are moved in the form of a turn-over membrane into and out of the tucking-in zone, and transversely moved fold-over members are merely hinged around the moulding edge, corresponding substantially to the movement of the front joint of the thumb when tucking in a covering. |
