Abstract
Abstract Apparatus and method for maintaining separation of multiple strands of metal produced in a slitting operation wherein a plurality of rollers and flatteners cooperate to properly tension the various strands while maintaining separation thereof whereby the various strands may be received onto a mandrel at a high rate of speed. As the various strands are received from the metal slitter, the strands pass over a roller and under a shaft which has a plurality of spacer members thereon. Flattening means are positioned on either side of a separator to thus prevent the strands from twisting. The strands then pass through two deflector rolls which retard vibration and prevent lateral movement of the strands.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
In a metal slitting operation comprising a tension stand having a first separator, a second separator, a plurality of flatteners, a plurality of rollers and drag tension rollers, the method of properly tensioning a plurality of metal strands for take-up on a mandrel comprising the steps of: passing strands over a first roller and under a first separator; passing strands through flattening means, over a second separator, and through flattening means; passing strands between drag tension rollers and onto a mandrel.
Claim 2
Dependent Claim
81 words
In a metal slitting operation comprising a tension stand having a first separator, a second separator, a plurality of flatteners, a plurality of rollers and drag tension rollers, the method of properly tensioning a plurality of metal strands for take-up on a mandrel comprising the steps of: passing strands over a first roller and under a first separator; passing strands through flattening means, over a second separator, and through flattening means; passing strands between drag tension rollers and onto a mandrel.
Claim 3
Dependent Claim
32 words
The method set forth in claim 1 to further include the step of: passing strands under a second roller and over a third roller before the strands are wound onto said mandrel.
Claim 4
Dependent Claim
86 words
A tension stand having a longitudinal axis and comprising: a first separator means; a second separator means; a first flattening means and a second flattening means, said first separator means being disposed above said longitudinal axis; said second separator means being disposed beneath said longitudinal axis; said first flattening means and said second flattening means being disposed along said longitudinal axis and on opposite sides of said second separator means, said first separator and said second separator being disposed on opposite sides of said first flattener.
Claim 5
Dependent Claim
86 words
A tension stand having a longitudinal axis and comprising: a first separator means; a second separator means; a first flattening means and a second flattening means, said first separator means being disposed above said longitudinal axis; said second separator means being disposed beneath said longitudinal axis; said first flattening means and said second flattening means being disposed along said longitudinal axis and on opposite sides of said second separator means, said first separator and said second separator being disposed on opposite sides of said first flattener.
Claim 6
Dependent Claim
53 words
A tension stand as set forth in claim 3 to further comprise a first and second roller disposed beneath said longitudinal axis and arranged such that the upper surface of said second roller is disposed above the lower surface of said first roller, said first roller being disposed adjacent said second flattening means.
Claim 7
Dependent Claim
50 words
A tension stand as set forth in claim 3 wherein said first flattening means and said second flattening means comprise first and second members, the said first member of each said flattening means being disposed above said longitudinal axis and the said second members being disposed beneath said longitudinal axis.
Claim 8
Dependent Claim
35 words
A tension stand as set forth in claim 5 wherein said first and second members are spaced apart sufficiently to permit passage of a metal strip therethrough and to prevent said metal strip from bending.
Claim 9
Dependent Claim
37 words
A tension stand as set forth in claim 3 wherein said first flattening means comprises a pair of T shaped members having a horizontal portion and a vertical portion, and T-shaped member having their horizontal members juxtaposed.
Claim 10
Dependent Claim
21 words
A tension stand as in claim 7 wherein one said T-shaped member has a spacer means on its said horizontal member.
Claim 11
Dependent Claim
45 words
A tension stand as set forth in claim 4 wherein said first and said second rollers are disposed adjacent each other so as to subject a strand passing along said longitudinal axis, under said first roller and over said second roller to a double bend.
Claim 12
Dependent Claim
35 words
A tension stand as set forth in claim 3 to further comprise a first roller disposed beneath said longitudinal axis, first roller and said first flattener being disposed on opposite sides of said first separator.
