Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
In an extrusion apparatus for applying a jacket having a plurality of embedded strands around a cable core continuously advancing downstream through said apparatus and comprising a guider for said core, a die, and means continuously urging a supply of jacketing stock around said core directly downstream of said guider, the improvement comprising, in combination, A. a substantial land within said die, B. walls in said guider defining a plurality of circumferentially distributed lengthwise passages for said strands, C. a plurality of shoes a. projecting radially through said stock at a station downstream of said guider and upstream of said land, b. aligned with said passages, and D. means for adjusting the radial projection of said shoes, said shoes pressing against said strands and fixing the depth of said strands within said jacket.
Claim 2
Dependent Claim
133 words
In an extrusion apparatus for applying a jacket having a plurality of embedded strands around a cable core continuously advancing downstream through said apparatus and comprising a guider for said core, a die, and means continuously urging a supply of jacketing stock around said core directly downstream of said guider, the improvement comprising, in combination, A. a substantial land within said die, B. walls in said guider defining a plurality of circumferentially distributed lengthwise passages for said strands, C. a plurality of shoes a. projecting radially through said stock at a station downstream of said guider and upstream of said land, b. aligned with said passages, and D. means for adjusting the radial projection of said shoes, said shoes pressing against said strands and fixing the depth of said strands within said jacket.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein said adjusting means comprise cam means projecting lengthwise through said die.
Claim 4
Dependent Claim
17 words
The apparatus of claim 2 wherein said cam means are adjustable from the face of said die.
Claim 5
Dependent Claim
14 words
The apparatus of claim 1 wherein the length of said land exceeds its radius.
Claim 6
Dependent Claim
108 words
An extrusion die having an exit face comprising A. a metal block, B. walls in said block defining a tapered entrance, C. a land coextensive with said entrance, D. walls defining a plurality of radial bores in said block and upstream of at least a major portion of said land, E. pin members supported in said bores and projecting inwardly therefrom, F. walls defining a like plurality of lengthwise holes communicating between said bores and said face, G. cam rods rotatably mounted in said holes and engaging said pin members, H. camming means whereby the projection of said pin members is adjusted by the rotation of said rods.
Claim 7
Dependent Claim
108 words
An extrusion die having an exit face comprising A. a metal block, B. walls in said block defining a tapered entrance, C. a land coextensive with said entrance, D. walls defining a plurality of radial bores in said block and upstream of at least a major portion of said land, E. pin members supported in said bores and projecting inwardly therefrom, F. walls defining a like plurality of lengthwise holes communicating between said bores and said face, G. cam rods rotatably mounted in said holes and engaging said pin members, H. camming means whereby the projection of said pin members is adjusted by the rotation of said rods.
Claim 8
Dependent Claim
23 words
The die of claim 5 wherein said camming means comprise lateral channels in said pins and eccentrically positioned circular projections on said rods.
Claim 9
Dependent Claim
19 words
The die of claim 5 wherein said pins terminate in narrow shoes aligned with the axis of said land.
Claim 10
Dependent Claim
43 words
The die of claim 5 wherein said strand comprises an undulatory wire and said pin members comprise walls defining slots only slightly exceeding the gage of said wire and having a length of at least full cycle of the undulations of said wire.
