Abstract
Abstract A device for winding toroidal deflection coils. A rotatable winding wheel has at least one annular flange on which a number of rollers which are each rotatable about their axis are provided, and is mounted on a frame for displacement with respect to the core to permit winding slant coils along geodetic lines, without developing slack in the wire being taken off.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A device for winding toroidal coils about a toroidal core having an axis, comprising a winding wheel rotatable about an axis, said wheel comprising a wire take-off device and a removable portion for insertion of a toroidal core to be wound, means for mounting the toroidal core and said winding wheel such that said winding wheel passes through an interior space of the core, means for providing relative angular motion about said core axis between said core and said winding wheel, and means for providing oscillatory displacement of said winding wheel axis with respect to said core in addition to said relative rotation, whereby slack in the wire may be taken up.
Claim 2
Independent Claim
112 words
A device for winding toroidal coils about a toroidal core having an axis, comprising a winding wheel rotatable about an axis, said wheel comprising a wire take-off device and a removable portion for insertion of a toroidal core to be wound, means for mounting the toroidal core and said winding wheel such that said winding wheel passes through an interior space of the core, means for providing relative angular motion about said core axis between said core and said winding wheel, and means for providing oscillatory displacement of said winding wheel axis with respect to said core in addition to said relative rotation, whereby slack in the wire may be taken up.
Claim 3
Dependent Claim
57 words
A device as claimed in claim 1, wherein said winding wheel comprises at least one annular flange coaxial with said wheel axis, and a multiplicity of rollers which are mounted to said flange and are rotatable about axes parallel to said wheel axis so arranged that said rollers form a reel about which wire can be wound.
Claim 4
Dependent Claim
56 words
A device as claimed in claim 1, wherein said relative motion means comprises a shaft having an axis coincident with said core axis, a table mounted on said shaft for rotation about said shaft axis, and means for pivoting said table about said shaft axis, and wherein said oscillatory displacement means is mounted on said table.
Claim 5
Dependent Claim
27 words
A device as claimed in claim 3, wherein said means for displacing provides at least a component of relative wheel axis movement parallel to said core axis.
Claim 6
Dependent Claim
68 words
A device as claimed in claim 1, wherein said core has upper and lower faces, and said means for providing relative motion comprises means for holding and rotating the core comprising a plurality of rollers for the lower side and a plurality of rollers for the upper side, so that the core can rotate between corresponding rollers, and programmable means for rotating said core about the core axis.
