Abstract

The invention relates to a compacting device, comprising two suction drums (17), wherein a suction drum (17) in each case is associatable with a pair of delivery rollers (7, 8) of drafting unit (2) of a spinning machine, wherein the pair of delivery rollers (7, 8) is made up of a bottom delivery roller (7) and a top delivery roller (8); wherein the suction drums (17) are rotatably supported, via a bearing, on a shaft that is fastened to a carrier element (41); wherein a suction channel (31) extends within the carrier element (41), and wherein the suction drums (17) each have a drive element (40) which in the operating position forms a drive connection with the bottom delivery roller (7). The invention is characterized in that a protective shield (42) for preventing lap formation is situated on the axle (19) of the clamping rollers (18). The invention further relates to a protective shield (42) and a corresponding textile machine.

Claims

exact text as granted — not AI-modified
1 . A compacting device, comprising
 two suction drums ( 17 ), wherein a suction drum ( 17 ) in each case is associatable with a pair of delivery rollers ( 7 ,  8 ) of a drafting unit ( 2 ) of a spinning machine, wherein the pair of delivery rollers ( 7 ,  8 ) is made up of a bottom delivery roller ( 7 ) and a top delivery roller ( 8 );   wherein the suction drums ( 17 ) are rotatably supported, via a bearing, on a shaft that is fastened to a carrier element ( 41 );   wherein a suction channel ( 31 ) extends within the carrier element ( 41 ),   wherein the suction drums ( 17 ) each have a drive element ( 40 ) which in the operating position forms a drive connection with the bottom delivery roller ( 7 ), and   wherein on the carrier element ( 41 ) two clamping rollers ( 18 ) are rotatably supported centrally in a bearing ( 20 ) on a shared axle ( 19 ), wherein for forming a clamping line, each of the clamping rollers ( 18 ) rests on the outer circumference of one of the two suction drums ( 17 ) under the action of a spring load,   
       characterized in that 
       a protective shield ( 42 ) for preventing lap formation is situated on the axle ( 19 ) of the clamping rollers ( 18 ). 
     
     
         2 - 15 . (canceled)
