Sleeve for Winding with a Roving

Abstract

A sleeve for winding a roving thereon includes an elongated sleeve body with opposite upper and lower end faces. A contact region is defined on the sleeve body to contact the roving and includes a paper layer. A capture structure is defined within the contact region and is configured to grip an end of the roving wound onto the sleeve body. The paper layer includes a surface structure of one or more of: a mechanically processed surface roughness section in the contact region; an additive in the contact region that increases surface roughness of the contact region; or a surface structure comprising overlapping individual paper layers forming the contact region.

What is claimed is: 
     
         1 . A sleeve for winding a roving thereon, the sleeve comprising:
 an elongated sleeve body with opposite upper and lower end faces;   a receptacle on the upper end face defined by an undercut;   an attachment on the lower end face configured to fixedly hold the sleeve for rotation;   a contact region defined on the sleeve body to contact the roving wound onto the sleeve body, the contact region comprising a paper layer;   a capture structure defined within the contact region and configured to grip an end of the roving wound onto the sleeve body; and   wherein the paper layer comprises a surface structure of one or more of:
 a mechanically processed surface roughness section in the contact region; 
 an additive in the contact region that increases surface roughness of the contact region, the additive located on an outer surface of the paper layer or within interior layers of the paper layer; or 
 a surface structure comprising overlapping individual paper layers forming the contact region. 
   
     
     
         2 . The sleeve according to  claim 1 , wherein the paper layer comprises a roughened structure on an outer surface thereof created by mechanical action in at least some sections of the contact region. 
     
     
         3 . The sleeve according to  claim 1 , the paper layer comprises surface cuts in at least some sections of the contact region. 
     
     
         4 . The sleeve according to  claim 3 , wherein the cuts are defined at a positive wedge angle (a) into the paper layer. 
     
     
         5 . The sleeve according to  claim 1 , wherein the additive comprises a bulk material. 
     
     
         6 . The sleeve according to  claim 5 , wherein the additive is covered by an outer layer of the paper layer paper in the contact region. 
     
     
         7 . The sleeve according to  claim 1 , wherein the surface structure formed by the overlapping paper layers comprises a diamond pattern. 
     
     
         8 . The sleeve according to  claim 1 , wherein the surface structure of the paper layer is cylindrical at least in the contact region and comprises an outside diameter in the contact region that varies between a minimum amount and a maximum amount, wherein the minimum amount is at most 2.0 mm smaller than the maximum amount. 
     
     
         9 . The sleeve according to  claim 1 , wherein the contact region comprises surface sections with different ones of the surface structures. 
     
     
         10 . The sleeve according to  claim 1 , further comprising a guide sleeve inserted between the attachment and the undercut. 
     
     
         11 . The sleeve according to  claim 1 , further comprising a spacer sleeve adjacent the undercut, the space sleeve having an axial length with an inside diameter defined by the undercut.
