Abstract
Abstract A mechanism for slitting and coiling work sheet or strip including a slitter from which a plurality of work mults of different thickness is obtained, a drag wipe engaging the various mults coming from the slitter and providing generally uniform frictional drag on the different mults, a common winder receiving the various mults and winding them into coils, and a looping pit interposed between the slitter and the drag wipe for receiving loops of some of the mults. In a preferred form a table means selectively covers the looping pit in order to aid in threading in the forward ends of the mults.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
In a drag wipe for adjusting the tension on a plurality of mults of work sheet or strip, a base, support means on the base, fluid pressure piston rod and cylindrical means mounted on the support means at opposite sides of the mult, a frame mounted on the piston rods at opposite sides, adjustable guides on the frame, pressure blocks loosely supported on the frame in the guides, and adjustable therefore with respect thereto, screw means operating between the individual pressure blocks and the frame for moving the pressure blocks relatively to the frame in the guides, an anvil extending across the base and adapted to engage the opposite side of the work from the pressure blocks, resilient means extending across the face of the individual pressure blocks from one side to the other and adapted to redistribute the pressure, and a looping pit interposed ahead of the pressure blocks for receiving loops of some of the mult when they are going through the drag wipe whereby each mult can be subjected to an individual pressure differing from that applied to the other mults.
Claim 2
Dependent Claim
184 words
In a drag wipe for adjusting the tension on a plurality of mults of work sheet or strip, a base, support means on the base, fluid pressure piston rod and cylindrical means mounted on the support means at opposite sides of the mult, a frame mounted on the piston rods at opposite sides, adjustable guides on the frame, pressure blocks loosely supported on the frame in the guides, and adjustable therefore with respect thereto, screw means operating between the individual pressure blocks and the frame for moving the pressure blocks relatively to the frame in the guides, an anvil extending across the base and adapted to engage the opposite side of the work from the pressure blocks, resilient means extending across the face of the individual pressure blocks from one side to the other and adapted to redistribute the pressure, and a looping pit interposed ahead of the pressure blocks for receiving loops of some of the mult when they are going through the drag wipe whereby each mult can be subjected to an individual pressure differing from that applied to the other mults.
Claim 3
Dependent Claim
125 words
A drag wipe of claim 1, in combination with frictional material extending over the resilient means and extending across the pressure blocks engaging the work, each of the pressure blocks having a slot elongated in the direction toward and away from the work, a pin extending through the slots of the various pressure blocks and supported on the frame, pivot means interconnecting the support means and the base at one side of the work, latch means interconnecting the support means and the base at the opposite side of the work, means for tilting the support means and the pressure blocks so as to insert new work and a guide roller on the support means which engages the stock as it passes through the drag wipe.
Claim 4
Dependent Claim
30 words
A drag wipe of claim 2, in combination with table means for selectively covering the looping pit in order to aid in threading in the forward end of the mult.
