Abstract
528,476. Coiling. NORDDEUTSCHE KABELWERKE AKT.-GES. May 8, 1939, No. 13727. Convention date, May 11, 1938. [Class 83 (iv)] In an apparatus producing long springs by rotating a supply reel about a stationary mandrel the coiled spring is discharged from the apparatus by a part of the apparatus which surrounds the mandrel eccentrically and performs a rolling movement in relation to the article. Alternatively the rolling movement may be effected by the mandrel. Wire 7 is coiled about a fixed mandrel 1 by a reel moving with a planetary motion. An eccentric bush 3 is rotated by a pinion 4 to eccentrically rotate a helically grooved bush 5 engaging the spring. Teeth 8 on the bush 5 engage teeth 2 on the mandrel 1 to effect rotation of the bush 5 for feeding the spring. Owing to the eccentric motion of the bush 5 friction between the coil and the bush is reduced. In a modification the mandrel is helically grooved and the cooperating bush is smooth. Two coils may be fed by rotating both the bush and the mandrel.
