Abstract: A method and apparatus for disposing the yarn end of a package in a further handling disposition such as, for example, in the tube of the package, is provided. A preliminarily repositioning device receives packages from a ring spinning machine or the like, some of the packaging having their yarn ends in a preferred preliminary disposition and other of the packages having their yarn ends in a disposition displaced from the preferred preliminary disposition. The preliminarily repositioning device repositions the yarn ends of packages having displaced yarn ends from a displaced disposition to the preferred preliminary disposition. Thereafter, a relocating device relocates the yarn end of each package having its yarn end in the preferred preliminary disposition from that disposition to the further handling disposition. An advancing device advances packages between the preliminarily repositioning device and the relocating device.

Abstract: A sliver feeding and opening device includes an outlet opening for passage of separated fibers to the rotor and an intake opening for the intaking of sliver to be separated into fibers. An intermediate opening is disposed in the chamber of the housing of the device at a location downstream of the outlet opening and upstream of the intake opening. An air stream reduction conduit extends from the intermediate opening to the outlet passage. The intermediate opening and the air stream reduction conduit conduct air from a revolving stream of air which revolves in the space between the opening roller and the cylindrical wall of the housing of the sliver feeding and opening device to prevent the revolving stream of air from detrimentally interfering with the orderly feeding of sliver at the intake opening to the opening roller.

A plurality of inclined platforms regularly spaced along the vertical endless belt translationally carry the packages to a package stripper which removes the supported packages from the platforms and loads the packages onto the conveyor.

The surfaces of the members are spaced from the slot, in respective opposite directions, by an amount sufficient to permit circulation of a fluid therebetween for removing dust and other debris, thereby reducing the distortion of the sensing of the yarn caused by the dust and other debris. The first and second members can be integrally formed from the housing which includes the slot.

Abstract: A method and apparatus for detecting and utilizing the bobbin circumference of cross-wound bobbins or cheeses in a textile machine producing the bobbins includes determining and evaluating the attained circumference of the cheese from measured values produced by sensors detecting the growth of the cheese. The measured values are continuously detected and processed and optionally stored in memory in at least one computer for further evaluation. A mathematical linkage symbolizing the current bobbin circumference cleansed of randomness in the current measured value pickup at very short time intervals based on the measured values for each winding station is continuously and repeatedly performed anew in the further evaluation. A parameter from the group consisting of current bobbin circumference, bobbin radius or bobbin diameter is calculated from the linkage.

Abstract: An apparatus for sensing characteristics of a traveling yarn in response to the shadow cast by the yarn includes a light emitting element and a pair of light sensing elements in opposed relation to the light emitting element. The yarn travels through a slot between the light emitting element and the pair of light sensing elements and is guided such that only a selected one of the light sensing elements is shadowed. An aperture assembly can be positioned between the light emitting element and the slot to channel the emitted light. The aperture assembly includes a plurality of apertures increasing in area in the direction away from the light emitting element and being framed by surfaces inclined away from the light emitting element and decreasingly inclined from frame to frame in the direction away from the light emitting element.

Abstract: A method for exchanging cans of sliver at a work station of a textile machine which handles sliver includes interrogating the work station to determine the presence of an interruption in the sliver handling operation, generating a signal to indicate the presence of an interruption, interrogating the work station concerning the availability of sliver and the proper feed of sliver and generating a follow-up signal after the generation of the sliver signal if the work station is again operating after a sliver can exchange has been executed in response to a signal indicating the non-availability of sliver or an improper feed of sliver. The method optimize the use of the sliver can transporter which transports fresh sliver cans to the work stations, by eliminating unnecessary movements of the transporter.

Abstract: A textile winding machine for producing cross-wound packages for subsequent use of the packages in pairs in simultaneously twisting and doubling yarn during which twisting and doubling the length of yarn drawn from one package of a pair is different from the length of yarn drawn from the other package of the pair. The winding stations are controlled to produce alternate packages with different lengths of yarn for use of alternate packages from each winding station as a pair of packages in the subsequent simultaneous twisting and doubling. A conveyor conveys the package pairs from the winding stations to a discharge end and the package pairs are deposited on the conveyor in either side-by-side relation or in sequence by the use of releaseable stops on platforms at the winding stations on which the wound packages are received and retained for release onto the conveyor after both packages of a pair have been wound.

Abstract: A method and apparatus for supplying sliver to the spinning stations of a spinning machine to wind a batch of a predetermined number of packages includes a sliver can transfer device, a sliver can conveying device, a sliver can filling device and a computer for controlling the operation of the various sliver can handling devices. Each spinning station is initially provided with a sliver can having a differing amount of sliver therein than the other sliver cans as the winding of the packages of the batch is commenced. The spinning stations are then continuously individually provided with fresh cans of sliver having a uniform amount of sliver therein during the normal running of the batch.

Abstract: A cutting assembly for severing trailing yarns on spinning bobbins being transported along a transport route includes a cutting apparatus disposed at a given level on one side of a transport apparatus for transporting spinning bobbins upright on mandrels along a transport route.

Abstract: In a yarn cross-winding apparatus of the type wherein a driven winding drum peripherally drives a bobbin and a traversing yarn guide applies yarn in a cross-wound fashion to the bobbin periphery, the problem of increased yarn winding density at the opposite ends of the bobbin is avoided by forming opposite peripheral end areas of the winding drum, whereat cross-winding yarn reversal occurs, with oppositely angled intersecting grooves forming a plurality of relatively staggered yarn engagement locations over the circumferential and axial extent of the peripheral end areas of the drum. The yarn engagement locations guide the yarn onto the bobbin at its opposite ends to resist deviation of the yarn from its cross-winding angle at the location of yarn cross-winding reversal.

An openable and closable sliver guide is provided at each spinning position in association with a sliver monitor which recognizes the presence and absence of sliver in the guide. A signal transmitter at each spinning position produces a can replacement signal when the monitor recognizes the absence of sliver in the guide. A program controller is associated with a signal receiver on the carriage to actuate exchange of the empty sliver can at the signaling spinning position with a full sliver can from the carriage.

Abstract: Apparatus for frictional surface driving of a textile bobbin during cross-winding utilizes three or more annular drive bodies rotatably supported axially adjacent one another on a central drive shaft with a transmission mechanism intermediate adjacent pairs of the drive bodies for coupling them in driven relation to the drive shaft and in speed-change relation to one another. The driving apparatus is thereby particularly adapted for peripheral driving of a conical bobbin during winding, at least two of the annular drive bodies preferably being utilized for peripheral driving engagement with the bobbin. The speed-change ratios are predetermined as a function of the rotational speed of the drive shaft and the conicity of the bobbin.
