Die schnellaustauschbare Membrane für Vakuumstreck- und/oder Trocknungsmaschinen für Lederindustrie

摘要

The invention relates to the rapid exchange of membranes for vacuum-stretch and/or drying machines for use in the leather industry, which saves both the machine operator and the membrane producer considerable amounts of time, labour and money. Known holding devices, which consist of at least two parts that have to be laboriously assembled by the machine operator or membrane producer, are replaced by an elastic connecting element (2), the entire surface of which is rapidly and simply glued or vulcanized onto the membrane (1) by the membrane producer. The elastic connecting element supports a plate (3) which has guide elements (3a) for the separate holding foot (4) that transmits the power transmitted by the machine. For more reliable attachment, the connecting element (2) and membrane (1) can be firmly joined to a counter plate (6). The one-piece holding device can also be embodied as an elastic bracket which by natural pretension hooks around the elastic connecting element (2) and upper surface of the membrane and on the side of the connecting element carries the guide elements (3a) for the separate holding foot (4).
