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.
