Abstract: This invention concerns a weft thread clamp with two jaws (1), (2) that can be moved to an opened and closed position, with at least one jaw (1) being directly moveable to the closed position via fluid pressure. The moveable jaw is preferably (1) a moveable unit, preferably made of a light material or in a compact form, which is moveable as a complete unit under the influence of the fluid pressure. Such a weft thread clamp is more reliable and simpler, and has a quicker reaction speed than the known pneumatically controllable weft thread clamps. This invention also concerns a system for the presentation of weft threads to a weaving machine equipped with one or more such weft thread clamps, as well as a weaving machine equipped with such a presentation system.

Abstract: Cutting device for a face-to-face weaving machine, comprising a cutting knife and an upper (2) and a lower cutting rail (3) with an intermediate distance (13) which may be adjusted by means of one or several screw means (3, 7), the device comprising at least one first screw means (3) having a first (4) and a second threaded part with a mutually opposite screw thread having practically the same pitch, each threaded part (4, 5) being designed in order to move a respective cutting rail as to height in the opposite direction, because of which the almost central position of the cutting knife with respect to the upper (2) and the lower (1) cutting rail is maintained, with the same deviation, when adapting the adjusted height of the jaw to a new height of the jaw.

Abstract: A device for separating warp yarns (16), (17) on a face-to-face weaving machine (13), comprising a separating means (1), (2) and a holding device (3,7,9,11), (4,8,9,12) which comprises a threaded adjusting means (11), (12), the adjusting means (11), (12) being provided in such a manner that its rotation will cause the separating means (1), (2) to be moved, because of which the holding height will be changed and adjusted and the adjusting means (11), (12) being able to maintain the adjusting means (1), (2) at the adjusted holding height. Moreover, the holding device (3,7,9,11), (4,8,9,12) will enable an adjustment in the warp-direction. With a similar device adjusting the holding height can be carried out in a very simple and accurate manner and whilst being adjusted the separating means (1), (2) will be unable to make any unwanted and dangerous movements.

Abstract: The invention relates to a face-to-face weaving machine with face-to-face shed forming, a twister device (1) being provided and relates further to a twister device (1) for a face-to-face weaving machine with face-to-face shed forming, the twister device (1) being situated between weaving frames (11), mutually provided with a free space and a weaving reed (12) and the twister device (1) being provided with means (2) for positioning a first series of warp threads (101) in waving means, means (3) to wave the first series of warp threads (101) and means (4) to cause a second series of warp threads (100) to move up and down, said means (4) to cause a second series of warp threads (100) to move up and down being driven by a driving device (19) provided with a casing (7), and said means (2) for positioning a first series of warp threads (101) in waving means, said means (3) to wave the first series of warp threads (101) and said means (4) to cause a second series of warp threads (100) to move up and down being attac

Abstract: This invention relates to a device for driving and guiding a rapier of a weaving machine, comprising a rotatable drive wheel (1) provided for driving a rapier rod (14) in a back and forth movement and a guide channel formed by adjustable guide bodies (10), (11) in order to guide the said rapier rod (14) according to a guide path in co-operation with the drive wheel (1), the guide bodies (10),(11) being part of a guide unit (9) which, as a whole, is adjustable in order to modify the distance between the guide path and the rotation shaft (2) of the drive wheel (1), and where the drive wheel (1) is continuously adjustable in the longitudinal direction of its shaft (2). With this device the clearances of the rapier rod with respect to the drive wheel can be performed easily, rapidly and with great precision, so that this device is able to work with a minimum development of heat and wear.
