Abstract
Abstract An apparatus is disclosed for use in combination with a slitter. The apparatus comprises a body member having teeth and grooves, permitting it to mesh with grooved slitting cutters, means for mounting the body member onto a slitter housing and means for aligning the body member so that a slit product can be readily extracted from the slitting cutters. The apparatus also prevents damage to the slitter in the event the slit product inadvertently breaks during slitting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A wire extractor for use in combination with a slitter having a stationary housing, a pair of arbors mounted in said housing and grooved cutters positioned on said arbors, comprising: a body member having teeth and grooves wherein said teeth are adapted to mesh with said grooved cutters; a holder for receiving and positioning said body member on said housing; an annular support ring for supporting said holder on said arbor so that the teeth of said body member mesh with the grooves of said cutter whereby axial movement of said body member is prevented; and means for aligning said body member so that the angular position of the teeth of said body member with respect to the grooved cutters is such that slit wire is readily extracted.
Claim 2
Dependent Claim
128 words
A wire extractor for use in combination with a slitter having a stationary housing, a pair of arbors mounted in said housing and grooved cutters positioned on said arbors, comprising: a body member having teeth and grooves wherein said teeth are adapted to mesh with said grooved cutters; a holder for receiving and positioning said body member on said housing; an annular support ring for supporting said holder on said arbor so that the teeth of said body member mesh with the grooves of said cutter whereby axial movement of said body member is prevented; and means for aligning said body member so that the angular position of the teeth of said body member with respect to the grooved cutters is such that slit wire is readily extracted.
Claim 3
Dependent Claim
36 words
A wire extractor as recited in claim 1 wherein said holder further comprises: a bore; and adjusting means positioned in said bore for maintaining the teeth of said body member in meshing engagement with said cutters.
Claim 4
Dependent Claim
32 words
A wire extractor as recited in claim 1 wherein said support ring further comprises means for varying the meshing engagement between said body member and said cutters by laterally moving said holder.
Claim 5
Dependent Claim
43 words
A wire extractor as recited in claim 1 further comprising: a pair of body members; a pair of holders for receiving and positioning said body members on said housing; and a pair of annular support rings for supporting said holders on said arbors.
Claim 6
Dependent Claim
31 words
A wire extractor as recited in claim 4 wherein said aligning means further comprises a strap fastened to the periphery of said support rings thereby preventing rotation of said support rings.
Claim 7
Dependent Claim
90 words
A wire extractor for use in combination with a slitter having a stationary housing, a pair of arbors mounted in said housing and grooved cutters positioned on said arbors, comprising: a pair of body members each having teeth and grooves at a contacting portion wherein said teeth are adapted to mesh with said grooved cutters and a pin adjacent the non-meshing end portion; means for mounting said body members onto said housing; and spring means disposed between said pins for urging said body members into meshing engagement with said cutters.
Claim 8
Dependent Claim
90 words
A wire extractor for use in combination with a slitter having a stationary housing, a pair of arbors mounted in said housing and grooved cutters positioned on said arbors, comprising: a pair of body members each having teeth and grooves at a contacting portion wherein said teeth are adapted to mesh with said grooved cutters and a pin adjacent the non-meshing end portion; means for mounting said body members onto said housing; and spring means disposed between said pins for urging said body members into meshing engagement with said cutters.
Claim 9
Dependent Claim
40 words
A wire extractor as recited in claim 6 wherein said mounting means further comprises: a bore adjacent the tapered front portion of said body member; and a pin fastened to said housing and adapted to be inserted into said bore.
