Abstract
A device (6) for holding and centering yam tubes (3) for processing while in a vertical orientation on transport disks (2), e.g., for removing a yam remnant (4) at a tube cleaning station. During such processing, the tubes are fixed in place by means of a height-displaceable centering arbor (12) coupled with a circuit arrangement which causes the operating height (h) of the centering arbor (12) to be automatically matched to the length of the respectively provided tube (3). An arresting arrangement (20) assure that the centering arbor (12) is securely fixed in place at each of its operating heights (h).
Claims8
A device for holding and centering a yarn tube while supported in an upright orientation on a transport disk disposed at a processing station, the device comprising a centering arbor for engagement with the yarn tube, a drive mechanism for moving the centering arbor upwardly and downwardly relative to the processing station for moving the centering arbor into engagement with the yarn tube, and an arresting means for fixing the centering arbor at an operating height, the arresting means comprising a circuit arrangement coupled with the centering arbor and with the drive mechanism and operable for automatically deactuating movement of the drive mechanism at an operating height of the centering arbor matched to the length of the yarn tube, and means for locking the centering arbor at the operating height.
