ABSTRACT:
A continuously fed band is coiled edgewise into a coil so that a maximum elongation of said band occurs at its edge which forms the external diameter of the coil, whereas the elongation uniformly decreases towards the opposite edge. At one side of the band, radially extending recesses are provided. The proposed device for effecting the novel method comprises a bed having mounted thereon a band tensioning means, a straight guide and an arched guide between which there is interposed a shaping member. Recesses provided in the bed receive a rotary disc having fingers which are uniformly spaced thereon and set into reciprocating motion with the aid of a cam. The continuously fed band is driven along two guide channels, one of which is straight and formed by the bed and the straight guide. The second guide channel is arched and formed by a portion of the rotary disc and the arched guide. The shaping member is constructed as a die with a wedge-shaped head. The working edge of the wedge extends radially and at an angle to the side surface of the rotary disc. A drive is provided to set the die in reciprocating motion.
