A method of producing a spinning cop in a pot spinning machine includes depositing yarn from a yarn guide onto an upper location of an interior of a spinning pot of the pot spinning machine to form an upper yarn deposit in the upper location; further depositing yarn from the yarn guide onto an area of the interior of the spinning pot spaced from the upper location to form a spinning cake spaced from the upper yarn deposit; and rewinding the spinning cake onto a tube to form a spinning cop and rewinding the upper yarn deposit onto the tube to form a top winding. Yarn forming the upper yarn deposit has a coarser yarn size than the yarn forming the spinning cake. During yarn deposit to form the upper yarn deposit the yarn guide is moved in one direction without traversing movement, and during yarn deposit to form the spinning cake the yarn guide is moved in one direction with traversing movement. Yarn windings are placed in parallel relation in the upper yarn deposit.

A yarn end preparation device for a cheese-producing textile machine includes at least one preparation nozzle having a mouth. A clamping device and a cutting device manipulate a yarn to be prepared for a subsequent operation. The cutting device is disposed in the immediate vicinity of the mouth of the at least one preparation nozzle. An additional loop former is also provided.

Yarn end preparation device for cheese-producing textile machines

At each work station of a textile machine producing wound bobbins, the yarn package on which yarn is wound is driven by a friction roller. In contrast to the conventional driving of the roller by a gear motor flanged to the housing of the work station, which has the disadvantage of requiring space and difficulty in removing and replacing the friction roller for maintenance, the present invention simplifies the friction roller drive by configuring the housing of the work station for the direct reception of the stator windings of the drive motor for the friction roller and mounting the friction roller and the rotor of the drive motor together on a continuous shaft.

Device for winding of yarn packages

A yarn splicing device for textile winding machines comprises a splicer mechanism for pneumatically joining yarn ends, upper and lower clamping and cutting devices, and suction-actuated yarn placement devices for placing the yarn ends to be spliced. According to the invention, one yarn placement device is a gripper tube normally parked in a zero position upstream of the yarn travel. The gripper tube has a spring-biased, pivotable gripping flap and a yarn placement hook for simultaneously placing both the lower yarn and the upper yarn to be spliced. For that purpose, one of the gripper tube and gripper tube flap carries the yarn placement hook forwardly for manipulating the upper yarn and a yarn guide disposed between the yarn placement hook and the pivot axis of the flap for placing the lower yarn.

A bobbin winding machine includes a multiplicity of winding stations for rewinding spinning cops. Each of the winding stations has a bobbin magazine for holding the cops and a bottle-like unwinding chamber having a bearing shaft and an arbor being pivotable about the bearing shaft. The unwinding chamber surrounds a cop being fixed on the arbor during unwinding. At least a portion of the unwinding chamber is formed by a cop chute being pivotable between a cop transfer position and an unwinding position. The unwinding chamber has a shell partly encompassing a cop during unwinding.

An automatic textile machine includes a multiplicity of work stations each having its own work station electronics for controlling progress of work done at the work station. A method for detecting a position of a cop carrier carrying a textile cop in the vicinity of a work station includes evaluating mistuning of an oscillator circuit as information with a secondary coil disposed on the cop carrier; detecting the information transmitted by the cop carrier with a sensor device; carrying the information to the work station electronics; and processing the information with the work station electronics to initiate further operations. An apparatus for detecting the position of a cop carrier carrying a textile cop in the vicinity of one of the work stations includes a secondary coil disposed on the cop carrier, and a sensor disposed in the vicinity the winding station. The sensor is connected to the winding station electronics and detects information transmitted by the cop carrier. The sensor has an oscillator circuit to be mistuned by the secondary coil.

A peg tray type carrier for transporting textile yarn tubes has a codable, readable and erasable electronic information carrying device such as a memory chip connected to a transmitting-receiving antenna arranged in the area of the central axis of the peg tray to achieve essentially the same effective contactless transmission interval to a compatible transmitting-receiving antenna of a reading, erasing and encoding device, which may be located for example stationarily along a peg tray transport conveyor, essentially without regard to the rotational disposition of the peg tray about its axis. Inductive, capacitive or electromagnetic forms of contactless coupling are possible for information transmission.

A textile machine apparatus for handling tubes having remaining yarn thereon includes a branch path for supporting tube support members, which individually support tubes thereon, for travel to and from the discharge assembly of a textile winding machine. The tube handling apparatus also includes a sensor disposed along the discharge transport path of the tube support members from the winding stations of the textile winding machine for discriminating among tubes having no yarn thereon and tubes having remaining yarn thereon. A guide member is operatively connected to the discriminating sensor for guiding the tube support members supporting tubes having remaining yarn thereon onto the branch path for transport therealong to a tube stripping device, which strips the tubes of the remaining yarn. The stripped tubes are then returned to the discharge transport path at a location upstream of the discriminating sensor. In one aspect of the invention, the discriminating sensor discriminates among tubes having less than a predetermined minimum amount of yarn thereon, tubes having more than a predetermined minimum amount of yarn thereon, and tubes having no yarn thereon.

The present invention provides an apparatus for use in classifying yarn package carrying tubes according to the amount of yarn, if any, thereon. The classifying apparatus includes a device for detecting the presence of yarn on a tube beyond a predetermined radial spacing from the axis of the tube. A device axially moves the detecting device relative to the tube during yarn detecting operation. A signal providing device is operatively connected to the detecting device for providing a signal in response to the commencement, the cessation, or the absence of detection of yarn by the detecting device. The signal providing device can also provide a signal to indicate both the commencement and the cessation of yarn detection. A device determines the axial location of the detecting device relative to the tube. Based upon information regarding the axial location of the detecting device at the time that a signal is provided indicating the commencement, the cessation, or the absence of detection of yarn, the extent of the yarn, if any, remaining on a tube can be calculated.

The invention relates to a method for operating an automatic bobbin winding machine, having a cop and tube transport system with a plurality of transport loops, which method makes the transport system usable for batch changing as well. According to the invention, when a batch of cops from a spinning machine runs out, i.e. when no further new cops are being delivered to the winding machine, the unwound tubes are carried in circulation in the transport system of the winding machine.
