METHOD AND DEVICE FOR SUPPLYING WEFT THREAD IN A WEARING MACHINE, AS WELL AS A BRAKE AND/OR DAMPER MECHANISM APPLIED THEREBY

摘要

Method for supplying weft thread in a weaving machine, in particular a pneumatic loom, whereby weft thread (2) is taken from a weft accumulator (5) and this weft thread (2) is brought in the shed (7) via insertion devices (6), and whereby this weft thread (2) is carried between the above-mentioned weft accumulator (5) and above-mentioned insertion devices (6) along a brake and damper mechanism (20) with which, during the insertion cycle, it is possible to exert a brake action as well as a damping action on the weft thread (2), characterised in that the weft thread (2) is carried, in the above-mentioned brake and damper mechanism, along at least one movable thread guide (21-24) on the one hand which can bring about a damping effect whith regard to the tension in the weft thread (2), and also along at least two other thread guides (22-23-24-25-39-40) on the other hand, of which at least one can be moved and which always allow for a bending, irrespective of the position of the first-mentioned thread guide (21-24).
