Abstract
Abstract Apparatus to produce a composite wire wherein a pair of pressure bonding calibered rollers rotatably disposed adjacent one relative to another are provided to form at their point of tangential proximity pressure bonding, oppositely opposed concavities with conjugate concavities formed adjacently thereof, the former concavities to engage and circumferentially compress the outer deposited metallic cladding material on a core wire and the latter concavities to receive and sever laterally extruded excess cladding material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
An apparatus to work and uniformly pressure bond metallic cladding material to core wire forming a covering for the latter to produce a composite wire comprising a pair of pressure-bonding calibered rollers rotatably supported on adjacent parallel axes to receive said composite wire therebetween, lip-shaped oppositely opposed concavities formed at the point of tangential proximity of said rollers to engage, compress and circumferentially bond the metallic cladding material to the core wire and circumferentially work said material to permit excess cladding material to extrude laterally thereof and conjugate concavities formed adjacent of said lip-shaped concavities to receive said extruded excess cladding material.
Claim 2
Independent Claim
102 words
An apparatus to work and uniformly pressure bond metallic cladding material to core wire forming a covering for the latter to produce a composite wire comprising a pair of pressure-bonding calibered rollers rotatably supported on adjacent parallel axes to receive said composite wire therebetween, lip-shaped oppositely opposed concavities formed at the point of tangential proximity of said rollers to engage, compress and circumferentially bond the metallic cladding material to the core wire and circumferentially work said material to permit excess cladding material to extrude laterally thereof and conjugate concavities formed adjacent of said lip-shaped concavities to receive said extruded excess cladding material.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 characterized in that said lip-shaped concavities established by said calibered rollers at the point of said tangential proximity in cross section are in the form of a diamond-shaped contour with acute angled apexes.
Claim 4
Dependent Claim
38 words
The apparatus of claim 1 characterized in that said lip-shaped concavities established by said calibered rollers at the point of said tangential proximity in cross section are in the form of a diamond-shaped contour with obtuse angled apexes.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1 characterized by pinching lands formed between said conjugate concavities and said lip-shaped concavities at the point of said tangential proximity to sever said excess cladding material upon being extruded laterally therebetween.
Claim 6
Dependent Claim
52 words
The apparatus of claim 1 characterized by shear dies having a blade surface disposed at an obtuse angle from a plane normal to the axis of said composite wire passed therethrough after being passed through said calibered rollers to reduce and finish the composite wire to the desired outer concentric circular contour.
Claim 7
Dependent Claim
84 words
Apparatus to work and uniformly pressure bond metallic cladding material formed as covering on a core wire to produce a composite wire comprising a pair of calibeRed rollers rotatably disposed in adjacent parallel alignment with their peripheral surfaces forming at their point of tangential proximity pressure bonding, oppositely opposed concavities in the form of a diamond-shaped cross-sectional contour to receive said composite wire and compress and circumferentially bond said metallic cladding material to said composite wire with excess cladding material being extruded laterally thereof.
Claim 8
Dependent Claim
84 words
Apparatus to work and uniformly pressure bond metallic cladding material formed as covering on a core wire to produce a composite wire comprising a pair of calibeRed rollers rotatably disposed in adjacent parallel alignment with their peripheral surfaces forming at their point of tangential proximity pressure bonding, oppositely opposed concavities in the form of a diamond-shaped cross-sectional contour to receive said composite wire and compress and circumferentially bond said metallic cladding material to said composite wire with excess cladding material being extruded laterally thereof.
Claim 9
Dependent Claim
31 words
The apparatus of claim 6 characterized by oppositely opposed concavities conjugate to each side of said pressure-bonding concavities at said point of tangential proximity to receive said extruded excess cladding material.
Claim 10
Dependent Claim
39 words
The apparatus of claim 7 characterized by pinching lands formed between said conjugate concavities and said pressure-bonding concavities at the point of said tangential proximity to sever said excess cladding material upon being extruded laterally of said pressure-bonding concavities.
Claim 11
Dependent Claim
65 words
The apparatus of claim 8 characterized by a series of shear dies each having a blade surface disposed at an obtuse angle measured from a plane normal to the axis of said composite wire passed therethrough after being initially passed through said calibered rollers to successively shave off excess cladding material and reduce and finish the composite wire to the desired outer concentric circular contour.
