Abstract
Abstract In a device for filling the interstices of the multi-stranded core of a cable, a die freely rotatable about an axis and having a plurality of passages opening from each end of the die, the passages being arranged in a cylindrical locus about the rotational axis of the die. The device itself consists of a housing defining a chamber holding filler material through which the core passes, one end of the housing being closed by the die and the other end of the housing having an aperture axially aligned with the die.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
A device for filling the interstices of a multistranded core of a cable with solid or viscous material, comprising a cylindrical die having a plurality of passages opening from each end thereof, the passages being arranged in a cylindrical locus about an axis, the die being journalled in mounting means and being freely rotatable about said axis, each of said passages being of a diameter to pass at least one strand of said core whereby the strands are spread apart on passing through the die, one end portion of the die projecting axially from the mounting means, said one end portion carrying passage means opening from the side thereof to define scoop means and opening axially from the free end thereof.
Claim 2
Independent Claim
121 words
A device for filling the interstices of a multistranded core of a cable with solid or viscous material, comprising a cylindrical die having a plurality of passages opening from each end thereof, the passages being arranged in a cylindrical locus about an axis, the die being journalled in mounting means and being freely rotatable about said axis, each of said passages being of a diameter to pass at least one strand of said core whereby the strands are spread apart on passing through the die, one end portion of the die projecting axially from the mounting means, said one end portion carrying passage means opening from the side thereof to define scoop means and opening axially from the free end thereof.
Claim 3
Dependent Claim
57 words
A device as claimed in claim 1 including a housing defining a closed chamber with a port opening into the chamber for the introduction of material under pressure, the die being mounted in one wall of the housing, and an aperture in another wall of the housing opposite the die to pass the core from the chamber.
Claim 4
Dependent Claim
51 words
A device as claimed in claim 2 in which the housing comprises a cylinder, one end of the cylinder being closed by a die mount having the die journally mounted therein, the other end of the cylinder being closed by an end cap having said aperture therein co-axial with said axis.
Claim 5
Independent Claim
125 words
A device for filling the interstices of a multi-stranded core of a cable with solid or viscous material, comprising: a cylindrical die having a plurality of passages opening into the chamber each to pass at least one strand of said core, the passages being arranged in a cylindrical locus about an axis; a die mount carrying the die, the die being freely rotatable about said axis, the die mount having an inwardly directed annular recess forming with the die a closed chamber, a port opening through the die mount into the chamber for the introduction of material under pressure; the die having passage means opening from the side thereof into the chamber to define scoop means and opening axially from one end of the die.
Claim 6
Independent Claim
125 words
A device for filling the interstices of a multi-stranded core of a cable with solid or viscous material, comprising: a cylindrical die having a plurality of passages opening into the chamber each to pass at least one strand of said core, the passages being arranged in a cylindrical locus about an axis; a die mount carrying the die, the die being freely rotatable about said axis, the die mount having an inwardly directed annular recess forming with the die a closed chamber, a port opening through the die mount into the chamber for the introduction of material under pressure; the die having passage means opening from the side thereof into the chamber to define scoop means and opening axially from one end of the die.
