Abstract
Abstract A ringless fiber spinning machine with spinning units including spinning chambers and adjacent separating devices preceding them. The inlet of the air distribution chamber for the necessary air is arranged on the spinning units and is connected with a least two of the zones of the spinning chamber which take the technological air. The distributing chamber of the such air has a case and a cover of the body of the separating device which enclose the recess in which are located the zones that get technological air. The cover is provided with holes connecting the distributing chamber with at least two of the said zones. A filter is preferably inserted into the inlet of the distributing chamber.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
In a ringless spinning machine with spinning units, including chambers and adjacent separating devices preceding the spinning units the improvement which comprises a distribution chamber on the spinning units, the chamber arranged to distribute air under pressure to at least two of the places of the spinning chamber which take said air, the chamber for distributing the air under pressure comprising a case and a cover for the body of the separating device enclosing recesses in which the places that receive said air are located, the cover being provided with holes connecting the distributing chamber with at least two of said places, and a filter disposed in the inlet of the distributing chamber, each of the places receiving said air from the distributing chamber being connected with it through at least one hole, the apparatus having the the following places taking the said air under pressure; an inlet condenser, a pressure table, a feeding roller, a combing-out roller, a cleaning chamber, and an outlet channel.
