    Abstract: A thermal polymer-bonding method includes initially placing into contact certain polymer-based first and second solid media at a first junction. A first superficial portion of the first solid medium is liquefying through the application of thermal energy to the first junction. The liquefied first superficial portion is superficially or topically applied to the second solid medium whereafter the topical application may be solidified via the action of cooling or withdrawal of thermal energy from the first junction. The solidification of the liquid elements, having maximized surface area contact between opposing media, bonds the first solid medium to the second solid medium. A third polymer-based solid medium may then be placed into contact with the first solid medium at a second junction, whereafter certain select second superficial portions of the first and third solid media may be liquefied, and re-solidified to bond the third solid medium to the first solid medium.

    Abstract: A method and apparatus for joining the ends of two profile sections (5, 6) such as two sealing, trimming or finishing strips for use in motor vehicle body construction, is shown. The two profile sections (5, 6) are clamped in respective retaining devices (18, 20) and a length of heat-responsive foil-like material (24) is unwound from a roll (22) into a position between the facing ends of the profile sections. Heaters (26-32) carried by a heater unit (34) are then moved into position between the ends of the profile sections (5, 6) and the foil (24). The outermost heaters (26, 30) heat the ends of the profile sections, and the innermost heaters (28, 32) heat the foil. The heaters (26 to 32) are then withdrawn, and the two retaining devices (18, 20) are then moved towards each other so as to move the ends of the two profile sections into contact with opposite sides of the heated foil (24) which thus heat-bonds the ends of the profile sections together. The retaining devices (18, 20) are then opened to release the joined profile sections. The heaters (26 to 32) are non-contact type heaters to avoid contaminating the foil or the ends of the profile sections. The use of the separate heaters allows the foil (24) to be heated to a temperature which is different from that of the ends of the profile sections, to achieve optimum bonding.
