Embodiment Construction

[0035] Figure 1a The main components of the current common drafting mechanism including the stretching and compressing mechanism of the spinning machine are shown in a cross-sectional view (the structure familiar to the technicians and the basic understanding of this mechanism are not described in detail here).

[0036] The fiber sliver 10 passing through the drafting mechanism is now Figure 1a It is drafted moving from right to left, and then it is twisted into yarn in a spinning mechanism (not shown) arranged downstream. Figure 1a , Figure 1b with Figure 1c Shows the details of this tension and compression mechanism.

[0037] The fiber sliver 10 drafted to the desired fineness leaves the drafting mechanism at the nip line 1 between the output pressure roller 5 and the lower drum 7. A compressor 3 for compressing the fiber sliver 10 is provided between the output pressure roller 5 and the supply pressure roller 6 arranged downstream. The compressed fiber sliver leaves the drafti...

Abstract

An arrangement for installing a compressor on a lower cylinder of a drafting machine, comprising a) a compressor with a seating surface, and b) a lower cylinder with smooth and non-smooth or corrugated peripheral surfaces, characterized in that the seating surface (9) Of the compressor rests not only on non-smooth or corrugated (11a, 11b) circumferential surfaces of the lower cylinder (7) but also on smooth peripheral surfaces.

Description

Technical field [0001] The invention relates to an arrangement structure for placing a compressor on a lower drum of a drafting mechanism. Background technique [0002] The compressor of the compression device of the drafting mechanism of the spinning machine is used to compress one or more fiber slivers stretched in the drafting mechanism in the compression zone. Regarding the direction of travel of the fiber sliver, the compression zone is arranged downstream of the drafting mechanism. Such a compressor is disclosed by EP1501967B1. [0003] In its working position, the compressor is placed on or against the rotating roller of the drafting mechanism. In this case, it is preferably the lower roller or lower roller of the output roller pair of the drafting mechanism. The contact surface of the compressor facing the rotating roller should not experience unfavorable wear in this case, so that the fiber from the fiber sliver to be compressed is lost in vain. The surface of the bott...
