## Abstract

Apparatus for winding stators or the like includes a winding form and a winding nozzle, rotatable about the form, for winding a wire on the form. A collecting tool or transfer tool is provided for receiving windings from the form, a stripper is provided to strip windings from the form onto the collecting tool and a clamping means is provided for clamping a wire between individual winding operations. The apparatus includes means for simultaneously moving the winding nozzle, stripping means and clamping means during the stripping of the windings from the form onto the collecting tool. Thus, the wire from the last-wound windings will be prevented from being drawn to a finer diameter when stripped from the form or it will not be necessary to pull additional wire out of the winding nozzle in which event, on starting the next winding process, there would be a strong jerk which could result in breakage.

## Claims

### Claim 1

In apparatus for winding electrical windings comprising a winding form, a winding nozzle rotatable about said form for winding wire on said form, a collecting tool for receiving windings from said winding form, means for stripping windings from said form onto said collecting tool, and means for clamping a wire between individual winding operations, said collecting tool comprising an inner ring of collecting lamellae and a concentrically disposed outer ring of cover strip lamellae, the improvement wherein, during said winding of wire on said form and during said stripping of windings from said form, said collecting lamellae are positioned within the cover strip lamellae in a retracted position such that the free ends of the collecting lamellae are positioned immediately beyond the free ends of the cover strip lamellae and such that they extend therebeyond a distance less than the thickness of a stator packet which is to receive a winding.

### Claim 2

In a method of stripping electrical windings from a winding form onto which said windings are wound onto a collecting tool, said collecting tool comprising an inner ring of collecting lamellae and a concentrically disposed outer ring of cover strip lamellae, said collecting lamellae being retractable and extensible relative to said cover strip lamellae, said stripping being effected by stripping said windings from said form onto said collecting tool, the improvement wherein, during said stripping, said collecting lamellae are retracted to a position wherein their free ends are positioned immediately beyond the free ends of the cover strip lamellae such that they extend therebeyond a distance less than the thickness of a stator packet which is to receive a winding.

### Claim 3 (depends on 2)

A method according to claim 2 wherein the collecting lamellae are retracted to said position before the winding of said electrical windings on said winding form.
