Abstract
Abstract A device for winding continuous windings with interlay sections mainly for transformers and the like. The device is characterized in that it is provided with a rotatably mounted base adapted to accommodate thereon a circumferential arrangement of bearing members used as a mandrel for laying the wire of the section being wound, and drives for effecting a step-like reciprocation of the bearing members in a radial direction with respect to the base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A device for forMing continuous windings with a number of winding sections one of which is wound from inside to outside wheras the other is wound from outside to inside, said device comprising: a rotatable base,radially movable bearing members mounted on said base for the winding of wire thereon, means cooperating with said bearing members for winding the wire on the base and rive means for each of said bearing members for locating said bearing members in fixed positions at the beginning of winding to provide a support for the initial turn of wire and for displacing the bearing members from the winding section at the end of winding to facilitate removal of the winding section, said drive means acting on said bearing members to effect displacement of said bearing members during winding to develop a uniform radial pressure upon the wire being wound.
Claim 2
Independent Claim
144 words
A device for forMing continuous windings with a number of winding sections one of which is wound from inside to outside wheras the other is wound from outside to inside, said device comprising: a rotatable base,radially movable bearing members mounted on said base for the winding of wire thereon, means cooperating with said bearing members for winding the wire on the base and rive means for each of said bearing members for locating said bearing members in fixed positions at the beginning of winding to provide a support for the initial turn of wire and for displacing the bearing members from the winding section at the end of winding to facilitate removal of the winding section, said drive means acting on said bearing members to effect displacement of said bearing members during winding to develop a uniform radial pressure upon the wire being wound.
Claim 3
Dependent Claim
109 words
A device as claimed in claim 1 wherein said bearing members are circumferentially arranged on said base, said means for winding wire on the base comprising a radially displaceable member extending over a portion of the extent of said base and having a guiding surface for guiding successive turns of wire onto the section being wound, said drive means being operative on said bearing members to displace the same successively as they enter the region where the wire is guided by the radially displaceable member to permit such guiding while the drive means outside said region acts on the bearing members to compress the wire turns against one another.
Claim 4
Dependent Claim
20 words
A device as claimed in claim 1 wherein said drive means comprises a separate, respective drive for each bearing member.
Claim 5
Dependent Claim
30 words
A device as claimed in claim 1 comprising a winding mandrel, stationary bearing members on said mandrel, and means mechanically connecting said mandrel for synchronous movement with said rotatable base.
Claim 6
Dependent Claim
22 words
A device as claimed in claim 1 comprising a separate drive means coupled to said base to drive the same in rotation.
Claim 7
Dependent Claim
28 words
A device as claimed in claim 5 comprising a winding mandrel, stationary bearing members on said mandrel, and means kinematically connecting said base and mandrel for synchronous movement.
Claim 8
Dependent Claim
43 words
A device as claimed in claim 4 wherein said stationary bearing members are circumferentially arranged on said mandrel with a spacing to allow said bearing members to enter therebetween when the latter are displaced from the winding section at the end of winding.
