Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 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 rod and cylindrical means mounted on the support means at opposite sides of the mults, 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 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, and resilient means extending across the face of the individual pressure blocks from one side to the other and adapted to redistribute the pressure.
Claim 2
Dependent Claim
139 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 rod and cylindrical means mounted on the support means at opposite sides of the mults, 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 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, and resilient means extending across the face of the individual pressure blocks from one side to the other and adapted to redistribute the pressure.
Claim 3
Dependent Claim
25 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.
Claim 4
Dependent Claim
44 words
A drag wipe of claim 2, in which each of the pressure blocks has a slot elongated in the direction toward and away from the work, and a pin extends across through the slots of the various pressure blocks and supported on the frame.
Claim 5
Dependent Claim
59 words
A drag wipe of claim 3, in combination with 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, and means for tilting the support means and with it the pressure blocks so as to insert new work.
Claim 6
Dependent Claim
27 words
A drag wipe of claim 4, in combination with a guide roller on the support means which engages the stock as it passes through the drag wipe.
