Abstract
Abstract Coil winding apparatus includes a stationary device and a movable device, one of the devices including a coil frame of curved noncircular configuration and the other device including a carriage. A mechanism is operatively connected to the movable device for moving it relative to the stationary device. A guide structure is aligned with and has a configuration conforming to that of the coil frame and a pair of guide members carried by the carriage guidingly engages the guide structure so as to thereby guide the movable device, during movement thereof by the moving mechanism, along a path conforming to the configuration of the frame. A supply source for a filamentary structure to be coiled onto the frame is carried by the carriage, and elastic forcestoring means such as a spring urges the guide members and the guide structure into engagement with each other so as to maintain the carriage and coil frame at least approximately at the same orientation one relative to the other and direct the filamentary structure tangentially onto the frame while issuing from the supply source at a location situated at a substantially constant distance from the location where the filamentary structure is wound onto the frame, whereby a substantially constant length of the filamentary structure extends from the supply source tangentially to the frame during winding of the filamentary structure thereon.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
243 words
In a coil winding apparatus, stationary means and movable means, one of said means including a coil frame of curved but noncircular configuration and the other of said means including a carriage, moving means operatively connected to said movable means for moving the latter relative to said stationary means, guide means aligned with and having a noncircular configuration conforming to that of said coil frame, a pair of guide members carried by said carriage and guidingly engaging said guide means so as to thereby guide said movable means, during movement thereof by said moving means, along a path conforming to the configuration of said frame, supply means carried by said carriage in front of said guide members in the direction of movement of said movable means for supplying a filamentary structure to be coiled onto said frame, and elastic force-storing means urging said guide members and said guide means into engagement with each other so as to maintain said carriage and coil frame at least approximately at the same orientation one relative to the other and direct said filamentary structure tangentially onto said frame at a location between said guide members while issuing from said supply means at a location situated at a substantially constant distance from the location where said filamentary structure is wound onto said frame, whereby a substantially constant length of said filamentary structure extends from said supply means tangentially to said frame during winding of the filamentary structure thereon.
Claim 2
Dependent Claim
243 words
In a coil winding apparatus, stationary means and movable means, one of said means including a coil frame of curved but noncircular configuration and the other of said means including a carriage, moving means operatively connected to said movable means for moving the latter relative to said stationary means, guide means aligned with and having a noncircular configuration conforming to that of said coil frame, a pair of guide members carried by said carriage and guidingly engaging said guide means so as to thereby guide said movable means, during movement thereof by said moving means, along a path conforming to the configuration of said frame, supply means carried by said carriage in front of said guide members in the direction of movement of said movable means for supplying a filamentary structure to be coiled onto said frame, and elastic force-storing means urging said guide members and said guide means into engagement with each other so as to maintain said carriage and coil frame at least approximately at the same orientation one relative to the other and direct said filamentary structure tangentially onto said frame at a location between said guide members while issuing from said supply means at a location situated at a substantially constant distance from the location where said filamentary structure is wound onto said frame, whereby a substantially constant length of said filamentary structure extends from said supply means tangentially to said frame during winding of the filamentary structure thereon.
Claim 3
Dependent Claim

Claim 7
Dependent Claim
25 words
The combination of claim 5 and wherein said elastic force-storing means comprises a spring urging said rollers and guide means into engagement with each other.
Claim 8
Dependent Claim
22 words
The combination of claim 1 and wherein said guide means is fixed to and forms an inner peripheral portion of said frame.
Claim 9
Dependent Claim
51 words
The combination of claim 1 and wherein said frame has a radially inner wall on which said filamentary structure is wound and said frame includes a flange of uniform width extending outwardly beyond and fixed to said inner wall and terminating in an outer peripheral edge which forms said guide means.
Claim 10
Dependent Claim
40 words
The combination of claim 8 and wherein said frame has an inner periphery directed inwardly away from said outer edge of said flange and said carriage has guide members which respectively engage said inner and outer peripheries of said frame.
Claim 11
Dependent Claim
29 words
The combination of claim 9 and wherein said guide members are respectively in the form of rollers turnably carried by said carriage and having rolling contact with said frame.
Claim 12
Dependent Claim
