ABSTRACT:
A method and device for producing a wave winding includes a stationary template which has a specific number of radially projecting arms corresponding to a specific number of waves desired on the wave winding. A winding nozzle through which a wire is fed is revolved by a revolving device along a winding path about the template. A respective forming element located between adjacent ones of the arms of the template and external to the winding path includes a wire engaging end adjacent the winding path. A moving device moves respective wire engaging ends of the forming elements to engage the winding wire and to push the winding wire inward between respective sequential adjacent arms of the template during each revolution of the winding nozzle about the template. Preferably, the winding wire is pushed to a position immediately adjacent flanks of the adjacent arms and this occurs by moving of the respective forming element radially inward when the revolving winding nozzle is located between the respective forming element and a following one of the two adjacent arms between which the winding wire is pushed. If desired each successive winding can be stripped off from the template by use of a transfer tool.
