Open-end spinning apparatus with fiber transport channel consisting of several channel structural components

Abstract

The present invention describes an open-end spinning machine which comprising a spinning rotor and a shell with a opening roller. The open-end spinning machine comprises a fiber feed duct which consisted of several duct components between a fiber opening roller and a rotor. The fiber duct includes at least one opening edge and a start section of the duct for receiving the fiber transported from the opening roller and a transport section connected with the start section. The open-end spinning machine comprises a duct module that including a fiber duct transporting section in the shell, and at least an edge module that including an opening edge section, wherein the edge module which is fixed on the duct independently constituting the start section of the duct. Preferably, a edge module including the transport section, and a edge module including the opening edge, are disposed in the shell, wherein the dege module is fixed in the shell and a start section of fiber duct is included.

Description

technical field [0001] The invention relates to an open-ended spinning machine with a spinning rotor and a card roll housing with card rolls and a housing for feeding fibers from the card roll to the spinning machine. A fiber channel of a yarn rotor, wherein the fiber channel consists of several channel parts arranged relative to each other. The fiber channel is provided with at least one fiber opening edge section, an initial section for receiving the fibers delivered from the carding roll, and a fiber delivery section connected thereto. Background technique [0002] In an open-ended spinning machine, the configuration of the fiber channels is decisive for the quality of the jet-spun fibers. Through the fiber channel, the fibers separated by the carding rollers are conveyed to the spinning rotor, where they are collected in the fiber collecting groove of the spinning rotor, and then sucked out from the fiber collecting groove and twisted into a fiber. During the entire pr...

Problems solved by technology

Another disadvantage is that in order to produce large and complex channel parts by powder injection casting, expensive casting molds must first be produced

However, when the edge parts including the carding edge are manufactured by powder injection casting, the surface of the carding edge is often rough and porous, and the required quality is often not achieved
