Problems solved by technology

Due to the limited draft on the ring spinning machine, only coarse ring yarns can be spun with this known method
However, this method cannot achieve the desired position of the can and the so-called tension drafting due to difficult operability.

Embodiment Construction

[0032] figure 1 Schematically shows the flow of the spinning machine. The vertical feed box 105 of the card 100 is supplied with cotton, for example, and the card 100 produces a fiber sliver FB from the cotton material by carding the cotton in a known manner. The fiber sliver FB can be stacked in the can 110 and then provided to a downstream drafting device 1 (such as figure 1 shown), or the fiber strip FB' is directly conveyed to the drafting device 1. The drafting device 1 produces a fiber strand FB' from one or more fiber strands FB (only one fiber strand is shown), according to figure 1 An embodiment of the present invention winds it on a bobbin 70 (see also the following figures). The drafting device 1 is downstream of a ring spinning machine 200 with a plurality of apron drafting units 204 (only one of which is shown), each of which feeds a bobbin 70 with a fiber sliver FB'. The ring spinning machine 200 produces the yarn G which is likewise wound on a bobbin 290 fro...

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.

Description

technical field [0001] The invention relates to a method of spinning without a flywheel for direct spinning of fiber sliver and a device with a drafting mechanism. Background technique [0002] Various attempts are known to spin the fiber sliver directly on the ring spinning machine. In this type of spinning method, the roving process can be omitted, so that costs and space can be saved. It is known, in particular, that fiber slivers with a fiber sliver titer of about 5 ktex are deposited in cans after the first drafting unit, which is a common part of the drafting device. These cans are then conveyed to a can creel, where they are withdrawn and introduced into a respective spinning box of the ring spinning machine. Since tension drafts can easily occur on the can creel, fine fiber slivers below 3.5 ktex are not used here. Since the draft is limited on the ring spinning machine, only thick ring yarns can be spun with this known method. However, this method cannot achieve...
