Flat cable conductor separating apparatus

Claim 2

In a conductor separator for separating conductors of a flat cable that has plural conductors and insulation material for retaining the conductors in uniformly spaced apart parallel relation, the insulation forming webs of reduced thickness between adjacent conductors so as to define longitudinally extending slots, the separator being of the type having means for shearing the webs at plural spaced apart sites corresponding to the location of the webs, improved apparatus for guiding the cable toward the shearing sites in precise alignment therewith comprising a first body having a plurality of parallel elongate ribs that are spaced from one another by an integral multiple of the distance between adjacent slots in the cable, a second body having a plurality of parallel elongate ribs indentical in spacing and location to the ribs in said first body and means for mounting said bodies so that said ribs of said bodies confront one another to define a path to said sites, said ribs being aligned with said sites, said mounting means including means for yieldably biasing said bodies and said ribs toward said path.

Claim 3

Apparatus for separating conductors of a flat cable of the type having plural conductors and insulation material for retaining the conductors in uniformly spaced apart parallel relation, the insulation forming webs of reduced thickness between adjacent conductors so as to define longitudinally extending slots, said apparatus comprising upper and lower shear rolls defining a bite and being constructed and arranged to shear at plural shear sites corresponding to the location of the insulation webs, means forming a path for guiding flat cable toward said bite, and transverse positioning means including a first body having a plurality of parallel elongate ribs that are transversely spaced from one another by an integral multiple of the distance between adjacent longitudinally extending slots in the cable, said ribs being aligned with said sites and extending toward said path for affording entry thereof into said slots, a second body having plural parallel elongate ribs identical in spacing and location to the ribs of said first body and means for yieldably biasing said first and second bodies toward said path so that the ribs of said second body confront the ribs of said first body and so that a flat cable can be introducted between said ribs of said bodies irrespective of the relative transverse spatial relation between said ribs and said slots, and so that said baising means causes entry of said ribs into said slots and consequent transverse movement of said webs into alignment with said shear sites.

Claim 4

Apparatus for separating conductors of a flat cable of the type having plural conductors and insulation material for retaining the conductors in uniformly spaced apart parallel relation, the insulation forming webs of reduced thickness between adjacent conductors so as to define longitudinally extending slots, said apparatus comprising upper and lower shear rolls defining a bite and being constructed and arranged to shear at plural shear sites corresponding to the location of the insulation webs, means forming a path for guiding flat cable toward said bite, and transverse positioning means including a first body having a plurality of parallel elongate ribs that are transversely spaced from one another by an integral multiple of the distance between adjacent longitudinally extending slots in the cable, said ribs being aligned with said sites and extending toward said path for affording entry thereof into said slots, a second body having plural parallel elongate ribs identical in spacing and location to the ribs of said first body and means for yieldably biasing said first and second bodies toward said path so that the ribs of said second body confront the ribs of said first body and so that a flat cable can be introducted between said ribs of said bodies irrespective of the relative transverse spatial relation between said ribs and said slots, and so that said baising means causes entry of said ribs into said slots and consequent transverse movement of said webs into alignment with said shear sites.

Claim 5

Apparatus according to claim 2 including means for limiting movement of said bodies toward said path to maintain said ribs in noncontacting relation to one another.

Claim 6

Apparatus according to claim 3 wherein said bodies have an inlet end at the extremities thereof remote from said bite, said bodies being formed to define surfaces that diverge from said path at said inlet end to facilitate introduction of a flat cable therebetween.

Claim 7

Apparatus according to claim 2 wherein said transverse positioning means forms an inlet end remote from said shear sites and wherein said apparatus includes controlling means for controlling the distance over which the conductors are separated, said controlling means comprising a frame defining a slot aligned with said inlet end, said slot being dimensioned to receive therethrough said flat cable, means for controllably closing said slot to effect selective clamping of said cable, means for mounting said frame to afford movement of said slot toward and away from said inlet end, and means for adjustably limiting the amount of movement of said slot toward and away from said inlet means.

Claim 8

Apparatus according to claim 5 wherein said frame mounting means includes a portion of said frame extending from said slot and having a distal end, means for pivotally supporting said distal end so that said slot traverses an arc about said pivotally supporting means in moving toward and away from said inlet end, said controlling means controlling the amount of pivotal movement of said frame.

Claim 9

Apparatus according to claim 2 in combination with a table defining la substantially flat surface in receiving relation to said shear sites at the outlet end thereof so that the cable traverses said surface at the outlet of said shear sites and a plurality of visible graduations on said surface for indicating the distance of travel of said cable through said shear sites.
