Abstract
Abstract In an apparatus for winding wire a spool upon which the wire is to be wound is held securely within the apparatus and a flyer having guide rollers to guide the wire upon the spool is mounted for rotary movement around the spool and for axial movement in a direction parallel to the axis of the spool. The rotary speed of the flyer can be regulated to maintain the tension of the wire constant. Limit switches are provided to define the limits of axial movement of the flyer and to reverse the direction of movement of the flyer so that the wire is wound upon the spool in uniform layers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
An apparatus for winding a strand, such as wire, cable, rope and the like, upon a spool comprising means for fixedly securing thereon a spool upon which the strand is to be wound, a rotatably mounted flyer movable around the spool to wind the strand thereon, and means for reciprocating said flyer between two end points in a direction parallel to the axis of the spool to wind the strand upon the spool and to control the axial movement of said flyer to wind the strand on the spool in uniform layers, said flyer comprising a cylindrical frame having a closed end and enclosing the spool at one of said end points, a hollow rotatable shaft attached to said frame closed end and the strand entering the closed end of said frame at the rotary axis to the spool through said hollow shaft, a plurality of rollers within the frame on the inner face thereof for guiding the strand entering the flyer such that outward movement of the strand within the rotating flyer resulting from centrifugal force is limited by the inner face of said frame whereby breaking of the strand is prevented and the strand is enclosed within said hollow shaft and frame during winding on the spool.
Claim 2
Independent Claim
209 words
An apparatus for winding a strand, such as wire, cable, rope and the like, upon a spool comprising means for fixedly securing thereon a spool upon which the strand is to be wound, a rotatably mounted flyer movable around the spool to wind the strand thereon, and means for reciprocating said flyer between two end points in a direction parallel to the axis of the spool to wind the strand upon the spool and to control the axial movement of said flyer to wind the strand on the spool in uniform layers, said flyer comprising a cylindrical frame having a closed end and enclosing the spool at one of said end points, a hollow rotatable shaft attached to said frame closed end and the strand entering the closed end of said frame at the rotary axis to the spool through said hollow shaft, a plurality of rollers within the frame on the inner face thereof for guiding the strand entering the flyer such that outward movement of the strand within the rotating flyer resulting from centrifugal force is limited by the inner face of said frame whereby breaking of the strand is prevented and the strand is enclosed within said hollow shaft and frame during winding on the spool.
Claim 3
Dependent Claim
29 words
An apparatus as claimed in claim 1 and means for regulating speed of rotation of the flyer to maintain the tension of the strand constant during the winding thereof.
Claim 4
Dependent Claim
57 words
An apparatus as claimed in claim 1 and means for sensing the tension of the strand during winding, and means responsive to said tension-sensing means for controlling the positions of the end points to reverse the axial movement of said flyer in the vicinity of the flanges of the spool upon which the strand is being wound.
Claim 5
Dependent Claim
48 words
An apparatus as claimed in claim 1 and limit switch means positioned to correspond to the reversal points of the axial movement of the flyer, and cam means on said flyer for contacting said limit switch means at each end point of the reciprocating movement of the flyer.
Claim 6
Dependent Claim
33 words
An apparatus as claimed in claim 1 wherein said spool securing means comprises a wheeled transportable carriage including a reinforcement plate having a take-up spin extending thereon upon which said spool is mounted.
Claim 7
Dependent Claim
62 words
An apparatus as claimed in claim 5 and comprising a housing enclosing the apparatus, there being an opening in a side of said housing through which said carriage is movable, a shield on said reinforcement plate, said opening conforming substantially to the outline of said shield, and means within said housing for aligning and positioning said carriage with respect to said flyer.
