摘要:
Weaving machine and method for introducing a weft thread (2, 3, 4) in a weaving machine, comprising introducing a specific weft thread (2, 3, 4) into a shed (8) at a lower speed than the normal speed for this specific weft thread (2, 3, 4), if a knot or irregularity (39, 41) has been detected in a specific weft thread (2, 3, 4).
摘要:
Device for forming a selvedge on a fabric comprising at least one thread guiding element (8-9) for what is called a leno thread (10-11), provided on an arm (16), whereby this thread guiding element (8-9) can be moved by means of a drive mechanism (24), characterised in that the drive mechanism (24) comprises the combination of an oscillating drive element (25); coupling parts (26), and a mechanism (27) with which the movement of one of the above-mentioned coupling parts (26) can be translated in a lateral movement of the above-mentioned thread guide (17-18).
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).
摘要:
Device for inserting weft threads in a weaving machine, more particularly an airjet weaving machine, which device (10) comprises at least one main blower (14-15) with a pertaining thread clamp (19; 19A-10B-19C-19D), characterized in that the thread clamp (19; 19A-19B-19C-19D) forms part of an element (20) configured in a modular manner.
摘要:
The present invention provides an actuator (10) for a shed-forming device for a weaving machine, the actuator (10) being arrangeable for moving at least one warp thread (1), the actuator (10) comprising an artificial muscle (11) having an input for receiving an actuation signal (12), the configuration of the artificial muscle (11) being variable in response to the actuation signal (12) in order to move the at least one warp thread (1). The use of an artificial muscle (11) as an actuator (10) has the benefit of a fast response when a change in configuration is required, reduced power requirements when compared to conventional actuators based on electric motors, compactness, robustness, reduced noise during operation and reduced cost to manufacture.
摘要:
In the case of a terry loom with a drive (26) for moving backrest (14) and breast beam (23) to and fro, provision is made for the drive (26) to comprise its own drive motor (31), which drives a shaft (33) which is connected to the holding elements (28, 30) of backrest (14) and breast beam (23) by means of transmission elements (37, 38).
摘要:
Weaving machine, in particular a multi-phase weaving machine of the type comprising a rotating weaving rotor (2) upon which are provided weaving shed-forming elements (12) to form several weaving sheds (20), as well as position selections means (5) which make it possible to put the warp threads (4) of a fabric (9) to be formed on the weaving shed-forming elements (12) provided on the perimeter of the weaving rotor (2) in such a manner that several weaving sheds ( 20) are formed, and means (6) to insert weft threads (7) in the formed weaving sheds (20), characterised in that said position selection means (5) comprise one or several position selection elements (17) that can be individually activated.
摘要:
Nozzle for supporting a weft thread in a weaving machine, provided with a flow-through canalisation (17) for a fluid flowing out in at least one outlet opening (18), characterised in that the nozzle (3) is at least partially composed of segments (19-20-30-37-47-52).
