Abstract

The invention relates to a spinning machine with a thread suction device, the spinning machine also has a plurality of spinning stations comprising a drawing-off apparatus and a twisting device, the thread suction device has a plurality of thread suction pipes (2, 102), each having at least one thread suction opening (3,103) for sucking yarn strips (17, 117) after the thread is broken, Each of the spinning stations is provided with the thread suction openings (3,103) with the air duct cross section. Each suction opening (3,103) is provided with a closing mechanism with closure members (1, 101) which can be movably held relative to the suction openings (3,103), and the closure members (1, 101) comprise guiding devices (12, 112), in the spinning process in the spinning station, the pressure inverse to the recovery force on the closure members (1, 101) is exerted on the guiding devices (12, 112), the closure members is held on the suction openings (3,103) by the pressure, and the air duct cross section is reduced.

Description

technical field

[0001] The invention relates to a spinning machine with a plurality of spinning stations, each comprising a drafting device and a twisting device, and a thread suction device with a plurality of thread suction tubes, the plurality of spinning Each of the thread suction tubes has at least one thread suction hole for sucking off the sliver after thread breakage, and the spinning stations are each assigned a thread suction hole with an air passage cross section. Background technique

[0002] In spinning machines, such as ring spinning machines, thread breakage occurs repeatedly during spinning. That is to say, the yarn sliver is cut off at the portion between the pair of delivery rollers of the drafting device and the yarn bobbin, thereby interrupting the spinning process. However, the drafting devices, which are usually not independently driven, continue to work and continue to feed the strands of material to the twisting device. The sliver that is continuous...
