Abstract
Abstract In an apparatus for making a wire helix by winding a wire about a mandrel by means of a rotating wire guide which withdraws wire from a storage reel, the mandrel is rotatably supported in the wire guide and has such a moment of inertia with respect to its axis of rotation that any torque transmitted by the rotating wire guide to the mandrel is insufficient to cause a revolving displacement of the latter.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
A winding apparatus for making a wire helix, comprising A. a wire guide body rotatable about a winding axis and including integral wire guide means orbiting about said winding axis, B. motor means operatively connected to said wire guide body for rotating the latter, and C. a mandrel rotatable about said winding axis and having 1. a first portion rotatably held by and with respect to said wire guide body and having a mass of a magnitude sufficient to prevent revolution of said mandrel in response to a torque applied thereto by said wire guide body during the rotation thereof and 2. a second portion forming a bar axially aligned with said winding axis and integral with said first portion; said wire being helically wound on said bar by said wire guide means.
Claim 2
Dependent Claim
133 words
A winding apparatus for making a wire helix, comprising A. a wire guide body rotatable about a winding axis and including integral wire guide means orbiting about said winding axis, B. motor means operatively connected to said wire guide body for rotating the latter, and C. a mandrel rotatable about said winding axis and having 1. a first portion rotatably held by and with respect to said wire guide body and having a mass of a magnitude sufficient to prevent revolution of said mandrel in response to a torque applied thereto by said wire guide body during the rotation thereof and 2. a second portion forming a bar axially aligned with said winding axis and integral with said first portion; said wire being helically wound on said bar by said wire guide means.
Claim 3
Dependent Claim
42 words
A winding apparatus as defined in claim 1, wherein said winding axis is disposed with respect to the vertical at an angle other than 0*; said first portion of said mandrel is formed as a pendulum with respect to said winding axis.
Claim 4
Dependent Claim
31 words
a second portion forming a bar axially aligned with said winding axis and integral with said first portion; said wire being helically wound on said bar by said wire guide means.
Claim 5
Dependent Claim
31 words
a second portion forming a bar axially aligned with said winding axis and integral with said first portion; said wire being helically wound on said bar by said wire guide means.
Claim 6
Dependent Claim
37 words
A winding apparatus as defined in claim 1, wherein said bar includes a part extending spaced from said winding axis; said apparatus further includes stationary holding means engaging the last-named part for preventing said mandrel from rotating.
Claim 7
Dependent Claim
42 words
A winding apparatus as defined in claim 1 including A. a yarn storing means held by said mandrel and B. means contained in said mandrel for applying said yarn to said bar between turns of said wire helix during the winding thereof.
Claim 8
Dependent Claim
27 words
A winding apparatus as defined in claim 4, wherein said yarn storing means is formed of a bobbin rotatably held by and with respect to said mandrel.
Claim 9
Dependent Claim
15 words
A winding apparatus as defined in claim 1, wherein said winding axis is horizontally disposed.
Claim 10
Dependent Claim
40 words
A winding apparatus as defined in claim 2, wherein said pendulum is rotatably supported at two spaced locations in said wire guide body; the space along and about said winding axis between said spaced locations is unoccupied by said mandrel.
Claim 11
Dependent Claim
16 words
A winding apparatus as defined in claim 1, including means for heating said wire guide body.
Claim 12
Dependent Claim
29 words
A winding apparatus as defined in claim 1, including braking means disposed upstream of said wire guide means for tensioning said wire during the winding thereof on said bar.
Claim 13
Dependent Claim
36 words
A winding apparatus as defined in claim 4, including A. a guide sleeve disposed in said mandrel to receive and guide said yarn and B. heating means associated with said guide sleeve for heating said yarn.
