High speed carrier with deckled underply

Abstract

A high speed yarn carrier or tube comprising a plurality of spirally wound plies of paper and incorporating, beneath the very thin overlapped outer surface defining ply, a strong underply provided with opposed deckle edges overlapped to a width no greater than that of the individual deckle edges. The deckle edge overlap is preferably less than a full overlapping whereby a small sink or depression is formed at the overlap.

What is claimed is: 
     
       1. A high speed carrier .Iadd.tube of predetermined inside diameter .Iaddend.for textile winding or the like comprising a multiple ply construction including.[., in addition to.]. a base defined by one or more base forming plies, a thin outer ply incorporating specific surface characteristics, and a carrier strengthening structural underply beneath said outer ply, said underply being defined by a strip spirally, wound on the base, .Iadd.at a predetermined angle.Iaddend., said underply strip having opposed deckle edges along the length thereof, said deckle edges, in the spirally wound strip, overlapping one deckle edge over the other deckle edge and being adhesively bonded to each other, .Iadd.said spirally wound strip specifically cut to a width narrower than the width which would produce a theoretically perfect overlap for the predetermined inside tube diameter and the predetermined winding angle for said strip so that .Iaddend.the width of the overlap of the .[.one deckle edge.]. .Iadd.edges .Iaddend..[.over the other deckle edge being.]. .Iadd.of said strip is at most .Iaddend.no greater than the width of the .[.other.]. deckle .[.edge.]. .Iadd.edges to uniformly form either a slight surface depression or a perfect overlap and to avoid a surface projection on said underply along the entire length of the tube. .Iaddend. 
     
     
       2. The carrier of claim 1 wherein the overlapping of the deckle edges is less than a full overlapping to form a slight surface depression and avoid a surface projection. .[.3. A high speed carrier of the type including a base defined by multiple spirally wound plies, said carrier including a strengthening ply spirally wound on and about said base, said strengthening ply having opposed deckle edges along the length thereof said deckle edges overlapping and directly engaging each other to a linear point less than the full width of the deckle edges and defining a slight 
     
     
        surface depression along the overlapped edges..]. 4.

        winding angle for the reinforcing ply..Iaddend. 5.
