Spinning method without a flyer as well as an apparatus with a draft system

Abstract

Proposed is a spinning method for the direct spinning of sliver (FB′) by means of a ring spinning machine ( 200 ), whereby one or more slivers (FB′), which said slivers were previously produced in a carding ( 100 ) or a combing machine, were drafted in a first draft system ( 4 ) situated upstream of the said ring spinning machine ( 200 ) to produce a single sliver (FB′), which, without the interposition of a flyer was made available to the ring spinning machine ( 200 ), in which the said single sliver (FB′), by means of a second draft system ( 204 ) is drawn and formed into a yarn (G). The invented method characterizes itself in that the sliver (FB′), at the output of the first draft system ( 4 ) has a band weight less than 2.5 ktex and is provided with a protective winding, and in that this sliver (FB′) in the second draft system ( 204 ) is subjected to a draft of more than 30. Likewise, an apparatus to carry out this method is also proposed.

1 . A spinning method without a flyer for the direct spinning of sliver (FB′) in a spinning machine ( 200 ), whereby, in a first draft system ( 4 ), located forwardly of a spinning machine ( 200 ), one or more slivers (FB′), which previously had been produced in at least one carding machine ( 100 ) or a combing machine, are drawn to one single sliver (FB′) which, without the interpositioning of a flyer, is presented to the said spinning machine ( 200 ) in which the sliver (FB′), is drawn by means of a second draft system ( 204 ) and formed into a yarn (G), therein characterized, in that the sliver (FB′) at the output of the said first draft system ( 4 ) possesses a band weight of less than 2.5 ktex and is provided with a protective winding and in that this sliver (FB′) in the second draft system ( 204 ) is subjected to a draw of more than  30 .
