Spin machine with several single drives

Abstract

In a spinning machine with at least one spinning station ( 1 ) which station possesses a feed drum ( 2 ), driven by a single drive ( 12 ), a disintegrator ( 3 ), a rotor ( 4 ), a withdrawal roll ( 5 ) and a spool roll ( 7 ), provision has been made, that the spinning station ( 1 ) has an additional single drive ( 15, 16, 17 ) respectively for the withdrawal roll ( 5 ) and/or the spool roll ( 7 ) and/or a paraffin roll ( 6 ) and that the speed of rotation ratio of the single drives ( 12, 15, 16, 17 ) can be preset to specified values.

1 . A spinning machine with at least one spinning station ( 1 ) which station possesses a feed drum ( 2 ) driven by a single drive ( 12 ), a disintegrator ( 3 ), a rotor ( 4 ), a withdrawal roll ( 5 ) and a spool roll ( 7 ), therein characterized, in that the spinning station ( 1 ) possesses additional single drives ( 15 ,  16 ,  17 ) respectively for the withdrawal roll ( 5 ) and/or for the spool roll ( 7 ) and/or for a paraffin roll ( 6 ) and in that the speed of rotation ratios of the single drives are capable of being preset to specified values.  
     
     
         2 . A spinning machine in accord with claim ( 1 ), therein characterized, in that one of the single drives ( 12 ,  15 ,  16 ,  17 ) is designed to be a lead motor operating with a preset speed of rotation or a preselected rotational frequency for at least one other single drive.  
     
     
         3 . A spinning machine in accord with    claim 2   , therein characterized, in that the single drive ( 12 ) of the feed drum ( 2 ) is designed to be a lead motor with a preset speed of rotation or a preselected rotational frequency.  
     
     
         4 . A spinning machine in accord with one of the foregoing claims, characterized by a power control center ( 20 ) assigned to each spinning position ( 1 ) for the regulation and electric current supply of the single drives ( 12 ,  15 ,  16 ,  17 ).  
     
     
         5 . A spinning machine in accord with    claim 4   , therein characterized, in that the power control center  20  is placed on or near one of the single drives ( 12 ,  15 ,  16 ,  17 ).  
     
     
         6 . A spinning machine in accord with one of the    claims 2    to    5   , therein characterized, in that of the single drives ( 12 ,  15 ,  16 ,  17 ) the lead motor thereof is connected to the others by at least one frequency generator ( 22 ,  24 ,  26 ), wherewith the preset speed of rotation ratios of the single drives ( 12 ,  15 ,  16 ,  17 ) can be implemented.  
     
     
         7 . A spinning machine in accord with one of the foregoing claims, therein characterized, in that at least one of the single drives ( 12 ,  15 ,  16 ,  17 ) is designed as a stepping motor.  
     
     
         8 . A spinning machine in accord with one of the foregoing claims, therein characterized, in that the single drive ( 16 ), designed as a stepping motor for the paraffin roll ( 6 ) follows the lead stepping motor ( 12 ) for the feed drum ( 2 ) by means of a power control center ( 20 ) as well as a frequency generator ( 24 ).
