Drafting Device of a Textile Machine

Abstract

A drafting device of a textile machine includes a roller and an opposed counter roller, each including a roller body and an axis of rotation, wherein the axis of rotation of one or both of the roller and the counter roller is mounted only at one end thereof. The roller is movably mounted between a resting position in which the roller body of the roller and of the counter roller are not in contact, and a load position in which the roller body of the roller and of the counter roller are pressed against one another along a contact region. The roller is movable from the resting position into a load position by moving into an intermediate position wherein the axes of rotation of the roller and of counter roller are aligned such that the contact region between the roller and the counter roller is smaller than in the load position of the roller.

1 - 10 . (canceled) 
     
     
         11 . A drafting device of a textile machine, comprising:
 a roller, and an opposed counter roller, wherein a fiber sliver is guidable between the roller and counter roller;   the roller and the counter roller each comprising a roller body and an axis of rotation, wherein the axis of rotation of one or both of the roller and the counter roller is mounted only at one end thereof;   the roller movably mounted between a resting position in which the roller body of the roller and of the counter roller are not in contact, and a load position in which the roller body of the roller and of the counter roller are pressed against one another along a contact region;   the roller movable from the resting position into a load position by moving into an intermediate position;   wherein in the intermediate position, the axes of rotation of the roller and of counter roller are aligned such that the contact region between the roller body of the roller and of the counter roller is smaller in an axial direction of the axis of rotation of the roller than in the load position of the roller.   
     
     
         12 . The drafting device according to  claim 11 , wherein the contact region in the intermediate position of the roller is smaller than that in the load position by a factor of at least 10. 
     
     
         13 . The drafting device according to  claim 11 , wherein in the intermediate position of the roller, the contact region is adjacent a front end of the roller and the counter roller opposite the mounted end. 
     
     
         14 . The drafting device according to  claim 13 , wherein the axes of rotation of the roller and of the counter roller are mounted to rotate at the mounted end by means of a bearing on the drafting device. 
     
     
         15 . The drafting device according to  claim 11 , wherein the axes of rotation of the roller and of the counter roller lie in a common plane at least in the load position. 
     
     
         16 . The drafting device according to  claim 11 , wherein in the intermediate position, the axes of rotation of the roller and of the counter roller form an angle (α) greater than 0° and up to or equal to 2.0. 
     
     
         17 . The drafting device according to  claim 16 , wherein in the intermediate position, the axes of rotation of the roller and of the counter roller run skewed to one another. 
     
     
         18 . The drafting device according to  claim 11 , further comprising a support, the support comprising a bearing for the mounted end of the roller, the support pivotable about a pivot axis, wherein the pivot axis of the support and the axis of rotation of one or both of the roller and the counter roller are skewed relative to one another in the intermediate position of the roller. 
     
     
         19 . The drafting device according to  claim 11 , further comprising a support, the support comprising a bearing for the mounted end of the roller, the support pivotable about a pivot axis, wherein the pivot axis of the support and the axis of rotation of the counter roller are parallel to one another, and the axis of rotation of the roller and the pivot axis of the support run skewed to one another at least in the intermediate position of the roller. 
     
     
         20 . The drafting device according to  claim 11 , further comprising a support, the support comprising a bearing for the mounted end of the roller, the support pivotable about a pivot axis, wherein the pivot axis of the support and the axis of rotation of the roller are parallel to one another, and the axis of rotation of the counter roller and the pivot axis of the support run skewed to one another at least in the intermediate position of the roller.
