ABSTRACT:
A method and the respective device for carrying out the method of applying a provisional protective covering to the exposed face that is not perfectly smooth (rough, furrowed, downy, fibrous, striated, or the like) of any products which have to be transported and/or stored and/or processed and/or installed by a subsequent assembly operation, particularly of profiled internal upholstery panels for vehicles, for example, for motor vehicles. A foil (2) of thermoplastic plastics material which is meant for forming the provisional protective covering, is laid out over the pandl product (1), is heated up to the thermoforming temperature, and is then sucked on the exposed face (101) of the product or panel (1) by a suction being peripherally applied to at least one point of the product or panel (1), and which spreads over the entire surface of the exposed face (101) thereof, thanks to the not perfectly smooth structure of said surface. Thus, the plastics material foil (2) is caused to adhere exactly to the profile of the product or panel (1) and after cooling down, it sticks with a certain strength to the exposed face thereof, while when required it can be easily detached and removed.
