<p>A metal frame carries vertical shafts(5) on which reels of sealing strip are rotatably mounted, the reels being located by collars(6). The strip passes around pulleys (27) to motor (or manually) driven pulleys(15). The latter have serrated grooves, and spring loaded freely rotatable pulleys(16) press on one side of the strip to ensure the pulleys(15) feed the strip to guides(24). The metal profile(8) to which the strips are to be applied is held between a fixed stop(13) and an adjustable spring loaded.</p> |
