Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
An extrusion guider for applying a jacket over an insulated cable core, said jacket comprising a plurality of lengthwise embedded metallic members, comprising, A. a support member comprising a. a tapered zone defining an entrance section, and a reduced exit section, b. a uniform bore extending from said reduced section, said bore comprising a smooth inside surface, and c. a plurality of straight evenly spaced flat lengthwise grooves for guiding said metallic members, in said inside surface, and, B. a plurality of tubular inserts for said support member each comprising a. an outside cylindrical surface closely fitting said bore, and cooperating with said grooves to form guide ports for said members, b. an inside surface closely fitting said core, c. a tapered tubular extension projecting from said support member, said insert being fitted therein, and d. an annular face terminating said extension, said face having a preselected edge thickness for determining the depth of saId wires in said jacket, said thickness being different for different of said inserts, and e. means for removably locking said inserts in said support member.
