A method and apparatus for moving individual yarn ends into a yarn disposition at a yarn end joining device in a winding station of a bobbin winding machine includes moving individual in succession a yarn end from a delivery bobbin to the yarn end joining device, and a yarn end from a take-up bobbin to the yarn end joining device by a single yarn manipulator device.

A method for checking operation of a pneumatic splicer for joining two yarn ends at a textile machine includes feeding splicing gas for a predetermined period of time to a splicer to be checked for splicing a particular yarn batch without having yarn ends laid in place in a splicing conduit of a splicer head of the splicer to be checked. At least one status variable of outflowing splicing gas is measured during the predetermined period of time at a given opening in the splicer head. A reference value is measured at another splicer producing replicable spliced joints meeting a previously defined quality and being identical to the splicer being checked, by feeding splicing gas to the other splicer without yarn ends being laid in place in the splicing conduit and measuring the reference value at a given opening in the splicer head. The at least one status variable is compared with the measured reference value and deviations are ascertained. The magnitude of the deviations is used as a basic criterion for evaluating the operation of the splicer to be checked, and satisfactory operation of the checked splicer is then resumed. An apparatus for checking the operation of the pneumatic splicer includes a test apparatus having a splicing gas carrier in the form of a measuring tube. The measuring tube carries an adaptor for connecting the measuring tube to one of the splicer heads and includes a device for detecting at least one status variable of the splicing gas.

A debris removing apparatus for a textile winding machine is provided and includes an air stream channeling device, an air drive device, and a structure forming an opposite opening. The air stream channeling device includes an intake opening and a pair of wall members each having a generally planar portion extending substantially parallel to a lateral plane on which a linear travel path of a yarn lies as the yarn travels between a supply package to another yarn package at a winding station of the textile machine. The generally planar portions channel air drawn in through the intake opening by the air drive device into an air stream which travels parallel to the lateral plane toward the traveling yarn. The air stream flows around the yarn and entrains debris on and around the yarn for transport away from the yarn. The air drive device, in one aspect of the invention, includes a suction housing through which suction is applied.

A suction tube for a fly frame, roving frame, ring spinning machine or the like for collecting broken ends of yarn at the outlet rollers of the machine. The suction tube is connected to a collection chamber through a flexible sealing sleeve that permits the suction tube to pivot between its operative and inoperative positions. The suction tube comprises a suction end disposed under the bottom roller of the outlet rollers that has a body portion formed with a suction opening therein, an opposite end connected to the flexible sealing sleeve, and a pair of side walls projecting upwardly from the suction end body portion toward the bottom roller and longitudinally beyond the suction opening on opposite sides of the yarn for confining the suction substantially to the bottom roller and the yarn path. The side walls also have upper edges which are arcuately shaped to correspond approximately to the shape of the bottom roller so that the upper edges will contact the bottom roller and space the suction tube from the roller when the suction tube is unintentionally forced upwardly toward the bottom roller, thereby preventing damage to the suction tube.

A dust-removal apparatus for textile machines and machine rooms includes a chamber containing dust-laden air, a clean-air chamber, a tube disposed between and separating the chamber containing dust-laden air from the clean-air chamber, at least part of the tube being a filter element, a suction device connected to the clean-air chamber, another switchable suction device in the form of a filter cleaning device connected to the tube, the tube having an inlet end, and a device for selectively closing the inlet end of the tube.
