In a multi-station cheese-producing textile machine (,) for rewinding delivery bobbins (,) of large volume, each work position (,) has a manipulating and transport installation (,) by which delivery bobbins (,) are transferred from a loading position (I) to a winding position (III). Each manipulating and transporting arrangement (,) has a horizontally arranged transport unit (,), and an essentially vertically arranged transport unit (,). Transport elements (,&Prime;) for receiving delivery bobbins (,&prime;, etc.) are arranged on the transport units (,) in a definitively shiftable manner for transfer between one transport unit (,) and the other transport unit (,).

Cheese-producing textile machine

A winding unit 2 of an automatic bobbin winder includes a suction nozzle 12 for aspirating from the surface 48 of a take-up bobbin 11 an upper yarn end portion 34 after a yarn break for subsequent placement into a splicing device 13. The suction nozzle 12 has a sensor device 35 for detecting the presence of the aspirated upper yarn and the sensor device is connected to winding unit computer 39. The suction device is connected via a cam transmission 27, 29 to a reversible drive 25 which can be driven by winding-unit computer 39 to cause the mouth 38 of the suction nozzle to execute reciprocatory pitching movements V, Z to assist the nozzle in properly aspirating the upper yarn.

In connection with a device for retracting and advancing a thread processing element in relation to a threadline it is provided that the retracting and renewed advancing is caused solely by switching on a drive motor in a direction opposite its normal operational direction of rotation. For this purpose a drive member, which is maintained fixed against relative rotation in this direction of rotation, and another drive member which can be rotated in this direction of rotation in relation to the first by way of a drive motor, are provided, which change a rotating movement into an axial movement.

Apparatus for moving a yarn processing device

A method used in conjunction with a yarn splicing device having a pneumatic splicing chamber, a compressed air line connecting the splicing chamber to a source of compressed air, an electromagnetic splicing valve disposed within the compressed air line and having two transitional positions (open and closed) for controlling delivery of the compressed air to the splicing chamber, and a control unit connected to the valve for initiating a transitional signal to the valve for opening and closing of the valve, the method including, after initiating the transitional signal to the valve, the steps of determining a value representing a characteristic of the changing air pressure prevailing in the compressed air line resulting from a transition of the valve from the open position to the closed position, comparing the determined value with a reference value, and generating an error signal if the difference between the determined value and the reference value is greater than a predetermined variance value. Preferably, the air pressure prevailing in the line is determined after a predetermined length of time following initiation of a transitional signal, and the generating of the error signal preferably includes the activation of an optical and an audible alarm. The reference value is preferably either operator-entered or calculated from other determined values from other similar splicing devices. The present invention also includes a device operating in accordance with the described method.

Method and device for testing a pneumatic splicing valve

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.

Yarn splicing device for bobbin-winding textile machines

Because of the pot spinning process, it is more difficult to automate the supply of empty tubes, respooling of the spinning cake on an empty tube, and the removal of the spinning cops in a pot spinning machine than with other spinning processors. The present invention provides a completely automatic exchange of spinning cops for empty tubes at the spinning stations of a pot spinning machine by utilizing the yarn guides of pot spinning stations to place full yarn cops produced thereat into an upright position on carriers located on a movable conveyor extending underneath the spinning pots. With the spinning cops deposited onto the conveyor and with the yarn guide returned to a spinning position, the conveyor can transport the carriers with the spinning cops away and can deliver empty tubes to the spinning stations for receipt by the yarn guides to continue the spinning process.

Transport system in a pot spinning machine

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.
