Abstract: A receiver for supporting one end of a bobbin tube in a spinning or bobbin winding machine has a tube-engaging plate member with a nose member mounted on the plate member for movement between a normal resting position and an operating position A yarn delivery device guides the yarn into the range of movement of the nose member. A contoured yarn clamping surface and a contoured yarn guide surface are formed on the plate member. The nose member initially catches the yarn and clamps it on the clamping surface, drawing the yarn end out of the delivery device, and then guides the yarn via the yarn guide contour in the direction of the middle of the bobbin tube. The nose member is thereby surrounded by a loop of the yarn and extends over the foot end of the tube in the direction of lengthwise the middle of the tube to orient the yarn loop adjacent to the winding area for the yarn reserve windings.

Abstract: The method and apparatus is used for tilting substantially rotationally symmetrical bodies, such as frustoconical bobbin bodies, from a shell surface thereof onto an end surface thereof. The body is moved in a given transport direction defining leading and trailing end surface of the body with the shell surface lying on a conveyor path. The movement continues until the body crosses a dividing palne. The dividing plane extends transversely between and defines edges of two path segments of the conveyor path. The body is stopped when the leading and trailing end surfaces are supported on different path segments. The edge of one of the path segments is subsequently selectively raised relative to the other of the path segments. The body is tilted about the riased edge onto the other of the path segments until the end surface located above the other of the path segments comes to rest on the other of the path segments. The tilted body is removed in the given transport direction.

Another carriage movable along the spinning machine supports a can manipulating mechanism equipped with sensors to recognize and distinguish empty and full cans on the transport carriages, the manipulating mechanism being operable in association with the sensors to transfer empty cans from the spinning positions to the empty can locations on the carriages and to transfer full sliver cans from the carriages to the spinning positions of the spinning machine.

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 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: 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.

Abstract: An open end spinning machine and an associated traveling sliver can replacement carriage are provided with cooperating components for automatically replacing empty sliver cans at the spinning positions of the machine with full sliver cans and threading up the sliver for spinning resumption. 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: A method and apparatus for reestablishing the spinning operation at a spinning station of an open end spinning machine after a yarn break or after completion of winding of a full package. A traveling piecing unit responds to signals at a spinning station that indicate that a yarn break has occurred, that a package changing operation has occurred, or that winding of a package has been completed. Independently, a traveling package changing unit responds to a signal indicating that winding of a package has been completed at a spinning station and performs the package changing operation. When the piecing unit responds to a yarn break at a spinning station, it locates and withdraws the end of broken yarn from the package and positions it in a position where the unit then feeds the end to the spinning element to piece it with new yarn being spun and then releases it to the package, which resumes winding.
