Abstract
Abstract An idler member is provided for use in changing the direction of travel of a moving web. The member has a cylindrical exterior surface which is adapted to be engaged by the moving web. A portion of the said exterior surface has fused thereto material deposits which are adapted to increase the frictional engagement between the idler member and the web.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
72 words
A rotary idler member for use with a moving web to effect a change in the direction of travel of the latter, said member comprising a cylindrical exterior surface of weldable material, and a bead of welding rod splatter substantially encircling said exterior surface and being fused thereto to effect roughening thereof and adapted to be frictionally engaged by the moving web whereby the web imparts rotational movement to said idler member.
Claim 2
Dependent Claim
72 words
A rotary idler member for use with a moving web to effect a change in the direction of travel of the latter, said member comprising a cylindrical exterior surface of weldable material, and a bead of welding rod splatter substantially encircling said exterior surface and being fused thereto to effect roughening thereof and adapted to be frictionally engaged by the moving web whereby the web imparts rotational movement to said idler member.
Claim 3
Dependent Claim
72 words
A rotary idler member for use with a moving web to effect a change in the direction of travel of the latter, said member comprising a cylindrical exterior surface of weldable material, and a bead of welding rod splatter substantially encircling said exterior surface and being fused thereto to effect roughening thereof and adapted to be frictionally engaged by the moving web whereby the web imparts rotational movement to said idler member.
Claim 4
Dependent Claim
72 words
A rotary idler member for use with a moving web to effect a change in the direction of travel of the latter, said member comprising a cylindrical exterior surface of weldable material, and a bead of welding rod splatter substantially encircling said exterior surface and being fused thereto to effect roughening thereof and adapted to be frictionally engaged by the moving web whereby the web imparts rotational movement to said idler member.
Claim 5
Dependent Claim
24 words
The idler member of claim 1 wherein said bead forms a random encircling pattern extending substantially the entire axial length of said exterior surface.
