Abstract
Abstract Helical, wire filaments are disclosed that may be encapsulated individually or nested in bundles that are themselves encapsulated within an elastomeric material to provide a reinforced fabric. The method and apparatus by which such filaments are formed pass straight wire, in individual or plural strands, through a bore in a movable working die. Each strand is cold worked around the flared orifice of the bore in the movable die and enters a corresponding bore in a fixed die means. The corresponding bores are eccentric, and the movable die plate is translated such that each bore therein describes an annular path concentrically outwardly of the corresponding bore in the fixed die means. The foregoing apparatus and method are particularly adapted to the manufacture of reinforced, elastomeric fabric, even to the point that, if desired, normally plated wire can be deplated prior to being encapsulated within the elastomer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A wire forming mechanism comprising, a first, working die plate and a fixed die means, said working die plate located in spaced relation with respect to said fixed die means, said working die plate being movable with respect to said fixed die means while remaining in constant spaced relation with respect thereto, at least one bore extending through said working die plate and presenting a flared aperture in opposition to said fixed die means, a bore extending through said working die plate, each bore in said working die plate being located eccentrically of a corresponding bore in said fixed die means.
Claim 2
Dependent Claim
101 words
A wire forming mechanism comprising, a first, working die plate and a fixed die means, said working die plate located in spaced relation with respect to said fixed die means, said working die plate being movable with respect to said fixed die means while remaining in constant spaced relation with respect thereto, at least one bore extending through said working die plate and presenting a flared aperture in opposition to said fixed die means, a bore extending through said working die plate, each bore in said working die plate being located eccentrically of a corresponding bore in said fixed die means.
Claim 3
Dependent Claim
51 words
A wire forming mechanism, as set forth in claim 1, in which said first working die plate is mounted on a first cross beam, means mounting said cross beam for translation such that the locus of points delineated by any point on the cross beam during movement thereof describes a circle.
Claim 4
Dependent Claim
47 words
A wire forming mechanism, as set forth in claim 2, in which the movement of said cross beam is occasioned by at least one, rotating, driving spindle, an adjusting head secured to rotate with said spindle, an eccentric connection securing said cross beam to said adjusting head.
Claim 5
Dependent Claim
111 words
A wire forming mechanism, as set forth in claim 2, in which a second cross beam mounts a second working die plate, said second working die plate also being mounted in spaced relation with respect to said fixed die means, at least one bore extending through said second working die plate and presenting a flared aperture in opposition to said fixed die means, a bore extending through said fixed die means corresponding to each bore through said second working die plate, means mounting said second cross beam for translation such that the locus of points delineated by any point on said second cross beam during movement thereof also describes a circle.
Claim 6
Dependent Claim
52 words
A wire forming mechanism, as set forth in claim 4, in which the movement of said first and second cross beam is occasioned by individual, rotating driving spindles, an adjusting head is secured to each said driving spindle, and an eccentric connection secures each said cross arm to its respective adjusting head.
Claim 7
Dependent Claim
23 words
A wire forming mechanism, as set forth in claim 5, in which means are provided to rotate said driving spindles in opposite directions.
Claim 8
Dependent Claim
77 words
A wire forming mechanism, as set forth in claim 5, in which each said spindle has a rotational axis and said eccentric connection comprises a T-slot in each adjusting head extending transversely of the rotational axis of the spindle to which said adjusting head is secured, a key rotatably supported on said cross beaM and slidably received in said T-slot, means to lock said key in selective eccentricity with respect to the rotational axis of said spindle.
Claim 9
Dependent Claim
46 words
A wire forming mechanism, as set forth in claim 6, in which each key is rotatably supported on its corresponding cross arm by a stud secured to each key and a corresponding bearing mounted on each cross arm, said studs being journaled within the corresponding bearings.
