Problems solved by technology

Moreover, due to the geometry of the known air-jet spinning stands, the sheath fibers are relatively tightly wound on the core fibers, so that the yarn cannot be used as a roving due to lack of further drawability

Embodiment Construction

[0052] At the beginning of the description of the figures, it should be expressly noted that the illustrated spinning stand 3 and elements potentially arranged upstream or downstream thereof are not drawn to scale. On the contrary, the individual figures only show schematic diagrams, which are intended to clarify the principle structure of the various components. In particular, in various cases in image 3 and Figure 4 The distances and diameters marked in represent values ​​in the figures that do not necessarily or directly represent the exact ranges according to the invention.

[0053] figure 1 Schematic showing details of a roving frame according to the invention. If desired, the roving frame may comprise a drafting unit 15 which is supplied with the sliver 2, eg in the form of a combined sliver. Furthermore, the roving frame shown comprises in principle a spinning table 3 spaced apart from the drafting unit 15 and having an inner swirl chamber 4 in which the sliver 2 ...

Abstract

A roving machine for producing a roving (1) from a sliver (2), has at least one spinning station (3) with a vortex chamber (4) having an infeed opening (5) for the sliver (2) and a roving forming spindle (6) extending at least partially into the vortex chamber (4). The vortex chamber (4) is associated with at least one air nozzle (8) from which the air can be induced to the vortex chamber (4). The spindle (6) has a draw-off channel (9) via which the roving (1) can be drawn out of the vortex chamber (4). In the region of the vortex chamber (4), the draw-off channel (9) has an inlet port (10) for the roving (1) to be drawn out of the vortex chamber (4), wherein the inlet port has an inner diameter (F), the value of which lies between 4 mm and 12 mm, preferably between 6mm and 8 mm.

Description

technical field [0001] The invention relates to a roving frame for producing rovings from sliver, wherein the roving frame comprises at least one spinning table with a swirl chamber with a feed opening for the sliver and at least partly A roving forming element in the form of a spindle extending into the swirl chamber, wherein the swirl chamber is associated with at least one air nozzle through which air can be directed into the swirl chamber, and wherein the spindle There is a withdrawal channel through which the roving can be drawn out of the swirl chamber. Background technique [0002] Roving frames for the production of rovings from slivers that are pretreated, for example by drawing, in most cases have been known from the prior art for a long time. The roving is then used as feed material for a subsequent spinning process in which the individual fibers of the roving are spun into a fiber yarn, for example by means of a ring spinning machine. During the production of t...
