Definitions
- the invention relates to a thread transport device for a textile machine, in particular for the weft thread of a weaving machine, according to the preamble of claim 1.
- Thread transport devices of the type mentioned are known for example from CH-PS 565 879.
- different thread transport device variants which have a rotating belt for receiving and transporting the thread and which can be driven at a variable speed.
- a thread transport device is also described, in which a circumferential belt that transports the thread is guided on the one hand between two conical level discs which can be changed in their distance and on the other hand runs over at least one deflection roller.
- a pressure roller presses the thread to be conveyed against the belt.
- the belt with prestress on pending pressure roller serves to compensate the change in length of the belt and on the other hand presses the transported thread on the belt.
- the thread transport devices shown only schematically in the document do not reveal the features required for actual use.
- the object of the invention is a thread transport device
- the belt should also allow small radii of curvature despite the sufficient strength for thread transport.
- the object is achieved according to the invention by the characterizing features of claim 1. Because the belt is provided with transverse ribs on at least one side, it can be made extraordinarily thin and nevertheless have sufficient inherent strength due to the transverse ribs, so that even the smallest radii of curvature can be mastered with the belt, and yet the belt has an adequate transverse has stability that ensures thread transport.
- the transverse ribs can be present on the underside of the belt, while the top is made smooth. This results in a particularly rigid design of the belt in the transverse direction.
- the embodiment according to claim 3 improves safe transport of the thread on the belt, in particular if a pressure roller interacts with the top of the belt, which has the counter-profile to the transverse ribbing.
- An embodiment of the belt according to claim 4 is particularly advantageous, since transverse rigidity of the belt and grip are optimal for the fade transport.
- the belt is designed according to claim 5, the best results are achieved.
- the side flanks of the belt can be perpendicular to the belt plane.
- the transverse stability of the belt and the possible driving force can be improved if the belt is designed according to claim 6.
- an embodiment according to claim 7 is advantageous.
- An embodiment of the thread transport device according to claim 8 is more advantageous. This is particularly the case when several thread transport devices are to be used and controlled together.
- a further development according to claim 9 is suitable for this purpose.
- the pivoting levers of the adjusting devices can then be fastened to a common pivotable axis, to which an adjusting device common to all thread transport devices engages, as stated in claim 13.
- An embodiment of the thread transport device according to claim 10 is also conceivable.
- Claim 12 designates the use according to the invention from Transport device in that several such thread transport devices are interconnected and arranged on a common drive shaft.
- the use according to claim 13 is particularly advantageous, in which not only a common drive but also a common setting of all thread transport devices is ensured.
- the thread transport device is suitable for various textile machines, such as knitting and weaving machines. It is particularly advantageous for a needle ribbon loom in which the
- Thread transport must be adapted to different weaving conditions.
- the use of the thread transport device according to claim 13 is particularly advantageous in the case of such needle ribbon looms with several weaving points.
