PCT No. PCT/DE95/01733 Sec. 371 Date Jun. 3, 1997 Sec. 102(e) Date Jun. 3, 1997 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96/17701 PCT Pub. Date Jun. 13, 1996Procedure and apparatus for the optimized manufacture of coil springs on automatic spring winding machines. It is the object of the present invention to offer both a procedure and an apparatus by which even in case of fluctuating values of the wire parameters high accuracies during the spring manufacture are guaranteed and simultaneously the scrap is minimized. The solution to this problem is that prior to the winding the wire parameters are determined and the measuring results are used directly for the adjustment of the position of the winding pins or winding rollers and/or the pitch wedge, and that the wire between the uncoiling device and the guiding assembly forms a loop whereby the lateral deflection of this wire loop is measured by a recognition unit and the uncoiling device carries out an additional movement controlled by the recognition unit. The invention is suitable for continuous inspection and correction of errors occurring on spring wires for the optimized manufacture of coil springs on automatic spring winding machines.
