Abstract
Abstract A textile machine for the open-end spinning of textile yarns including a plurality of spinning stations each of which is provided with a trash collection chamber for collecting trash from fibre fed to a spinning element at the station, and trash removal apparatus comprising an air exhaust chamber common to the trash collection chambers for removing trash from the chambers. Each trash collection chamber having an outlet leading from the interior thereof and the air exhaust chamber having an inlet leading to its interior. Said machine including means for intermittently connecting each outlet and the inlet so as to provide an intermittent flow connection between each trash collection chamber and the air exhaust chamber whereby to purge the trash collection chambers of trash.

Total Claims: 9
Claim 1
Independent Claim
150 words
A textile machine for the open-end spinning of textile yarns including a plurality of spinning stations, each station being provided with a trash collection chamber for collecting trash from fiber fed to a spinning element at the station, said machine also including trash removal apparatus comprising an air exhaust chamber common to the trash collection chambers and moveable shutter means for connecting and disconnecting each trash collection chamber and the air exhaust chamber so that the trash collection chambers are intermittently purged of trash, each trash collection chamber leading to an outlet port individual thereto, wherein the outlet ports register with inlet ports provided in one wall of the air exhaust chamber, and wherein the shutter means comprises an endless belt which has an aperture therein and which is moveable between the registering ports for periodically creating a flow passage between each outlet and inlet port through the belt aperture.
