Abstract
To fold a hollow profile (1), of an extruded thermoplastic material with a cladding foil (2) of aluminum on one surface and a temp. gradient from one wall of the hollow profile to the other wall (11,12), a hot shaping tool (4) is pressed against the uncoated wall (12) surface and force it against the facing wall (11). The wall compression forms a folding line across the wall (11,12) surfaces, at right angles to the cladding foil (2). The profiled body (1) is heated to its softening point. The side walls of the profile are supported while the hot shaping tool (4) is applied, and then they are shaped to conform to the folding line. The position of the folding line is determined where the profiled body has to be manipulated, where one wall surface is covered by the cladding foil (2), and within the foil area, or outside the foil area. After the folding line has been shaped, the profile body material is cooled at least at the folding line. A number of folding lines are imposed on the profile body, with simultaneous operations of heating a body section while the tool holder (3) presses the tool (4) into a folding line, to prepare the section for the next folding line. Each folding line is cooled after it has been shaped. A single shaping station is used, with the profile moved progressively through it. A cladding foil can be applied to a wall area in sequence, before the fold line is imposed. After the fold line has been formed, the side walls are folded inwards. A heated body can be inserted into the fold line, to form a pivotal part of the finished fold. The body is pushed into the heated profile by the tool holder (3), and then heated when in position, to be embedded in place when the side walls are folded inwards. The cladding foil covers the folded profile surface, and a stiffening web can be welded in place by two layers of weldable material. The insert can have an L-shaped cross section, or cylindrical, and its outer surface can be splined. The insert can also be a spiral. An independent claim is included for a folded profile body, where an insert at the fold can be of metal or a synthetic materials.
