Vacuum belt conveying device for guiding a moving web, in particular a web threading strip of a paper or board web, having an air-permeable transport belt guided endlessly in a loop with an upper run and a lower run, and a device arranged within the loop for applying a vacuum to the inner side of one of the runs of the transport belt in order to hold the web firmly on the transport belt, in which the device for applying a vacuum is formed by means of at least one long-gap ejector, which in each case has an air jet injector having a large number of air outlet nozzles along the inlet side of the long gap and, on the inlet side, is positioned at a distance under the inner side of the run which is provided to hold the web firmly.

A yarn splicing device with a splicing channel that can be charged with compressed air for the pneumatic connection of two yarn ends. The yarn splicing device has two rotatably seated prism elements, each of which is pivotable between a non-splicing position and a splicing position. The two prism elements are designed such that in the splicing position, a splicing channel is formed between them.

Yarn splicing device

A device (,) for holding and centering yam tubes (,) for processing while in a vertical orientation on transport disks (,), e.g., for removing a yam remnant (,) at a tube cleaning station. During such processing, the tubes are fixed in place by means of a height-displaceable centering arbor (,) coupled with a circuit arrangement which causes the operating height (h) of the centering arbor (,) to be automatically matched to the length of the respectively provided tube (,). An arresting arrangement (,) assure that the centering arbor (,) is securely fixed in place at each of its operating heights (h).

An apparatus for automatically forming yarn reserve windings selectively on either end of an empty tube prior to winding a yarn package thereon utilizes a threaded spindle and spindle nut assembly for supporting one of a pair of tube clamping plates for selective longitudinal displacement of a tube clamped therebetween during rotation of the tube to place the yarn reserve windings thereon. The hand of the threaded connection between the spindle and spindle nut determines the longitudinal direction in which the tube is displaced and, in turn, determines the end of the tube about which reserve windings are to be formed. In one embodiment, the spindle and spindle nut assembly are exchangeable for a like assembly formed with opposite threads, thereby to alter the longitudinal direction of tube displacement. In another embodiment, an interiorly and exteriorly threaded bushing is interposed between the spindle and the spindle nut, to form oppositely mating threads between the bushing and the spindle and between the bushing and the nut. Set screws are provided to selectively fix the nut with respect to the bushing or, alternatively, to fix the spindle with respect to the bushing, thereby to change the longitudinal direction of tube displacement without necessitating an exchange of the spindle and nut assembly.
