Suction device on spinning machine

Abstract

The invention relates to a suction device on a spinning machine. A suction device for two drafting device units (2, 3) arranged next to each other of a spinning machine, comprising a collector pipe (12) and a two suction ducts (26, 30), the two outwardly directed openings (17, 18) of the two suction ducts are directed with respect to the yarn (G) delivered from the respective drafting device unit (2, 3), Wherein the ends of the suction pipes opposite the outer openings (17, 18) lead through the inner openings (32, 33) to the common collector pipe (12). In order to simplify the production of the known suction devices and to avoid clogging, it is proposed that the outwardly pointing openings (17, 18) of the suction pipes (26, 30) point in opposite directions and that the suction to the collector pipe (12) The openings ( 32 , 33 ) of the straws are coaxially opposite each other.

Description

Suction device on spinning machine Technical field The present invention relates to a suction device for two drafting device units arranged next to each other of a spinning machine, comprising a collector tube and two suction devices extending from the collector tube and extending in opposite directions. The suction tube, and the outwardly directed openings of the two suction tubes point to the yarn delivered from each drafting device unit, wherein the ends of the two suction tubes opposite to the outer opening lead to the common collector tube through the inner opening. Background technique A particular problem with spinning machines is that in the event of a thread break, the fibrous material still conveyed from the drafting device unit must be conveyed away so that it does not enter the spinning element in an uncontrolled manner. For this purpose, suction devices are used, in which for each spinning station, a suction pipe is arranged near the flow of fiber material. Such ...
