Adjustable spinning distance

Abstract

The invention relates to air spinning frames for the production of spun thread ( 2 ) from a staple fibre strand ( 3 ), comprising a drafting unit ( 4 ) followed by a spinning box ( 5 ) with a twisting chamber ( 9 ) and a spindle ( 8 ). The invention was based on the task to provide a design by means of which the distance between the drafting unit ( 4 ) and the spindle ( 8 ) can be newly adjusted in a fast and simple manner. This task has been solved according to the invention by attaching an adjusting device ( 10 ) to adjust the distance (I) between the drafting unit and the spindle ( 8 ).

1 . Spinning place ( 1 ) of an air spinning frame for the production of spun thread ( 2 ) from a staple fibre strand ( 3 ), comprising a drafting unit ( 4 ) followed by a spinning box ( 5 ), whereby the drafting unit ( 4 ) comprises a pair of drafting unit discharge rollers ( 6 ) with a clamping line ( 7 ) and whereby the spinning box ( 5 ) comprises a twisting chamber ( 9 ) with a spindle ( 8 ), characterized in that an adjusting device ( 10 ) is provided to adjust the distance (I) between the clamping line ( 7 ) of the pair of drafting unit discharge rollers ( 6 ) and the spindle ( 8 ).  
     
     
         2 . Spinning box ( 5 ) for air spinning frames for the production of spun thread ( 2 ) from a staple fibre strand ( 3 ), with a twisting chamber ( 9 ), which preferably comprises a spindle ( 8 ), characterized in that an adjusting device ( 10 ) is assigned to the spinning box ( 5 ), which device serves to adjust the position of the spinning box ( 5 ).  
     
     
         3 . Drafting unit ( 4 ) for air spinning frames for the production of spun thread ( 2 ) from a staple fibre strand ( 3 ), with a pair of drafting unit discharge rollers ( 6 ) with a clamping line ( 7 ), characterized in that an adjusting device ( 10 ) is assigned to the drafting unit ( 4 ), which serves to adjust the position of the drafting unit ( 4 ).  
     
     
         4 . Adjusting device ( 10 ) according to the  claims 1  to  3 , characterized in that the adjusting device ( 10 ) consists of an eccentric ( 11 ).  
     
     
         5 . Adjusting device ( 10 ) according to  claim 4 , characterized in that the eccentric ( 11 ) comprises bearings ( 12 ,  12 . 1 ,  12 . 2 ,  12 . 3 ) for the eccentric, which are interchangeably or adjustably fastened on the frame ( 13 ) or on the adjustable component ( 4 ,  5 ).  
     
     
         6 . Bearing ( 12 . 3 ) for the eccentric according to  claim 5 , characterized in that the bearing ( 12 . 3 ) for the eccentric is mounted in a guide on the frame ( 13 ) were it is adjustable by means of a screw and a spring.  
     
     
         7 . Bearing ( 12 . 4 ) for the eccentric according to  claim 5 , characterized in that the bearing ( 12 . 4 ) for the eccentric comprises a hole  14 . 1  arranged off-centre for the mounting of the eccentric shaft ( 11 ), whereby the bearing ( 12 . 4 ) for the eccentric can be mounted in different locations.  
     
     
         8 . Adjusting device according to  claim 4 , characterized in that the eccentric ( 11 ) comprises a bearing ( 12 ) for the eccentric, which allows the swivelling of the adjustable component ( 4 ,  5 ).  
     
     
         9 .
