Adjustment device for drafting device drafting distances

Abstract

The invention in the sector of textile technology relates to a housing ( 1 ) with a roller pair ( 2 ) mounted in it, whereby the housing and the roller pair ( 2 ) are for preference constituent part of an apron drafting device ( 3 ). The roller pair ( 2 ) consist of a bottom roller ( 4 ) and a top roller ( 5 ), which together form a nip or grip line ( 6 ). Both rollers are mounted in the housing ( 1 ), whereby one roller ( 5 ) is mounted rigid or essentially only movable in the housing ( 1 ) in the plane ( 7 ) formed by the two axles of the rollers ( 4, 5 ). The other roller ( 4 ), by contrast, is mounted so as to be movable in the housing ( 1 ) in such a way that the nip or grip line ( 6 ) can thereby be moved. According to the invention, the roller ( 4 ) mounted in the housing ( 1 ) so as to be movable exhibits an apron ( 8 ).

1 . A housing ( 1 ) with a roller pair ( 2 ) located inside it, whereby the housing ( 1 ) and the roller pair ( 2 ) are for preference constituent parts of an apron drafting device ( 3 ), whereby the roller pair ( 2 ) consist of a bottom roller ( 4 ) and a top roller ( 5 ), which together form a nip or grip line ( 6 ) and which are mounted at the housing ( 1 ), whereby one roller ( 5 ) is mounted rigid or essentially only movable in the housing ( 1 ) in the plane ( 7 ) formed by the two axles of the rollers ( 4 ,  5 ), and the other roller ( 4 ) is mounted so as to be movable in the housing ( 1 ) in such a way that the nip or grip line ( 6 ) can in this way be moved, 
 characterized in that    the roller ( 4 ) which can be moved in the housing ( 1 ) carries an apron ( 8 ).
