A tube transport assembly is provided for transporting yarn packages on a textile machine. The tube transport assembly includes a vertical transport component for transporting yarn packages between vertically spaced locations. Each yarn package, which is in the form of yarn built on a tube, is individually fixedly supported on a tube support member and each tube support member includes an engagement portion for engagement by a post of a carrier member to thereby effect support of the tube support member by the carrier member. The carrier members are mounted to a flexible endless belt at uniform spacings therealong and are moved in an upward run past a feed location at which tube support members are fed to the carrier members for engagment and support thereby. A pair of transfer plates at the feed location guide the tube support members being engaged by the carrier members to insure that the tube support members are fully seated on the carrier members. The tube transport assembly also includes a pair of release guide plates at a discharge location for effecting release of the tube support members from the carrier members.

A yarn end loosening apparatus for a textile machine includes first and second chamber portions which are positionable to form a gas guide chamber for directing jet streams of gas against the yarn package therein to effect loosening of a yarn end. A movement device selectively moves the first chamber portion between the chamber 4 main position in which it forms a gas guide chamber with the second chamber portion, a clearance position in which it permits a tube support member which supports a yarn package to travel away from the winding station of the textile machine and a travel blocking position in which a following tube support member which supports a fresh yarn package is prevented from traveling beyond the unwinding location at which the yarn package is unwound. Another movement device is also provided for moving the second chamber portion to separate each tube support member from a subsequently following tube support member. The chamber movement devices include vertical shafts on which the chamber portions are mounted for pivoting of the chamber portions about vertical axes.

A housing is mounted on a column outwardly of a package conveyor at the rear of the machine. A pair of support arms are connected to gears of a gear assembly in the housing and extend at a downward inclination inwardly toward the machine. One of the arms is mounted above the other arm and is longer so that package supporting rods extending from the ends of the support arms will be substantially parallel in a generally horizontal plane for receipt of packages positioned thereon at the winding station. The housing is vertically movable to lower the support arms for deposit of the package onto the conveyor. The support arms pivot through arcs sufficiently long to clear the rods of the package upon raising of the housing and connected support arms into position for receipt of the next package. A synchronization shaft connects the gear assemblies at the other winding stations for synchronous operation of pivoting of the support arms, and a synchronization belt extends along the machine for synchronized raising and lowering of the housing and support arms at all of the winding stations.

A winding station of an automatic winding machine, includes a holder, a movable mounting mandrel supported by the holder for receiving a tube of a feeding bobbin, a bobbin delivery slide for feeding a bobbin to the mounting mandrel, an unwinding accelerator for accelerating unwinding of a thread from the bobbin, and a captively controllable displacement apparatus associated with the holder for at least approximately parallel displacement of the mounting mandrel between a tube mounting position below the bobbin delivery slide and an unwinding position below the unwinding accelerator.
摘要:
A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

A yarn cleaner for cleaning defects from a yarn, by means of a head for measuring at least one yarn parameter for comparison against cleaning limits determined for the yarn parameter. If the cleaning limits are exceeded, a defect in the yarn is indicated whereby intolerable defects may be cut out from the yarn. The yarn cleaner is set up for cleaning an effect yarn, also called a novelty or fancy yarn, formed from an alternating thinner webs and thickened effects in the yarn. At least one value of the yarn parameter is predetermined for webs and for effects and the cleaning limits of the yarn cleaner are adjusted such that they lie outside the predetermined value of the web parameter and outside the predetermined value of the effect parameter.

A tube transport assembly is provided for a textile machine system in which tubes having yarn or the like wound thereon are transported to, and empty tubes are transported from, a textile machine. Two different transport apparatus are each operable to transport a different kind of tube support member along a respective endless transport path. In one aspect of the present invention, an alternating positioning device alternately positions the two types of tube support members and a tube transfer device is operable to transfer the tubes and full yarn packages from the type of tube support members on which they are initially supported to the other type of tube support members. In one embodiment of the tube transport assembly, the alternating positioning device is a rotatable annular disk having a plurality of tube support member retaining positions uniformly spaced annularly thereon. In another embodiment of the present invention, the alternating positioning device controls the feed of tube support members to a coextensive travel path in which both endless transport paths are coextensive, the feed of the tube support members being controlled to produce an alternating arrangement of the two different types of tube support members.
