Abstract: A guide rod assembly for a Jacquard loom is described which is narrower (10 mm or less), instead of 13 mm of conventional guide rods. This reduction in width is attained reducing the overall height of the magnet system integrated in the guide rod. The magnet system has a support member in the form of an iron core with an elongated or oval cross-section, with an excitation coil wound around the iron core. Pole strips are in contact with both front faces of the iron core. The respective top surfaces of the pole strips are spaced apart by less than 13 mm.

Abstract: An equipment of a weaving machine in which pile warp yarns (7–13), (16–22) extend through the space between the reed dents and are distributed between a number of pile warp yarn systems and provided on the weaving machine to weave a pile fabric. A group of pile warp yarns (7–22) extend through each space between the reed dents and comprise pile warp yarns of at least two pile warp yarn systems (7–13), (16–22). Because of this it is possible to weave pile fabrics having higher pile densities at a certain reed setting. It is an easy and quick method to modify the equipment of a weaving machine, maintaining the reed setting and the pile warp yarns of each space between the reed dents being distributed between at least two pile warp yarn systems. Furthermore, a weaving process is provided in which, per space between the reed dents the pile warp yarns (7–13), (16–22) of at least two pile warp yarn systems are supplied and a pile fabric woven in that manner.

Abstract: On the one hand, the invention relates to a device for exerting a return force on at least one harness element of the harness of a Jacquard weaving machine, comprising at least one return spring (2) provided with means of attachment (1) for attaching the return spring (2) to retaining means (4) being immovably provided, said means of attachment (1) being provided with a positioning opening (6) for positioning the means of attachment (1) with respect to the retaining means (4), and a fixing opening (7) for fixing the means of attachment (1) to the retaining means (4), a spring connection (8) being provided between the positioning opening (6) and the fixing opening (7), in such a manner that the means of attachment (1) are able to move from positioning opening (6) to the fixing opening (7) with respect to the retaining means (4), but after having been fixed will be unable to move back from the fixing opening (7) to the positioning opening (6) with respect to the retaining means during operation or transport of

Abstract: The invention relates to a shedding device comprising at least one electric rotary actuator having an output shaft (11) that is designed to rotate a pinion (21) which is engaged with a rack (22), said rack being connected to a control heald (3) of a warp end (4) by means of a load transfer element (24).

Abstract: A shed-forming device and a method for using it are provided for creating a shed of warp yarns in a weaving machine. The shed-forming device includes a plurality of yarn separating elements operably disposed to one another within the weaving machine. The yarn separating elements individually separate the warp yarns into operational zones between the yarn separating element. A fluid supply apparatus supplies fluid to the yarn separating elements in the shed-forming device. The yarn separating elements direct the fluid to contact the warp yarns, forcing the warp yarns to form changeable sheds to allow proper weaving.

Abstract: A first (1) and a second connecting means (2) which may be connected in a detachable manner in order to connect a first and a second cord, more particularly a lifting cord and a harness cord of a Jacquard machine, the first connecting means (1) comprising an elastically deformable coupling element (3) which may be received in a receiving part (4) of the second connecting means and may be retained in axial direction, the second connecting means (2) comprising a passage (5) through which the coupling element (3), compressed in the radial direction, may be moved to the receiving part (4) and the coupling element (3) in the receiving part (4) having the possibility of adopting a larger radial dimension than is necessary to be moved through the passage (5), so that the coupling element (3) snap-fits in the receiving part (4). In the receiving part (4), the coupling element (3), by rotation around the longitudinal axis (A), may be brought into a disengaging position in which it is not retained.

Abstract: A host computer is used in a supporting system for supporting a user of a plurality of looms. The host computer includes a database section for storing specifications information relating to specifications of each of a plurality of looms, the specifications information including apparatus information relating to an operating apparatus provided in each loom, and an advice information providing section for receiving query information sent via a communications way, and identifying a loom based on the received query information, and creating advice information with respect to the identified loom based on specifications information extracted from the database section with respect to the loom, and providing the advice information.

Abstract: An assembly for controlling the reciprocating movement of the upper and lower frames of a shed-forming device of a weaving loom wherein on the chassis on either side of the shed-forming device two cams are provided which are each in engagement with the end of an offset lever fitted on a shaft to which is connected a balance beam. The ends of the balance beam are connected to the first ends of two connecting rods which have their other ends articulated to first and second rocking levers. The first rocking lever is split having oppositely oriented spaced arms which are separated by the second rocking lever. The first rocking lever is fitted on a pin pivoting in a bearing on the chassis. The second rocking lever is mounted to rotate about the pin of the first rocking lever and the first and second rocking levers are connected to the upper and lower frames by short and long articulated levers.

Abstract: In a weaving loom, an assembly for controlling the reciprocating movement of the upper and lower frames of the shed-forming device which assembly includes a shaft of which the ends are each associated with the ends of two connecting rods by way of eccentrics and which connecting rods are articulated on rocking levers whose arms are pivotally associated with short and long levers attached respectively to the upper and lower frames of the shed-forming device.

Abstract: An interactive real-time, distributed control system for textile weaving machines including real time, interactive bi-directional communications centrally manages the whole range of activities of a weaving room. Microcontrollers at each weaving machine control most of the routine weaving functions and operations, but communicate in real time with a central computer which provides large-scale data storage and analysis. Easy, consistent automatic machine set-ups result from electronically downloading cloth style and dobby control data from the central computer to the weaving machine microcontrollers. Because communications between the microcontrollers and the central computer as well as much of the analysis performed by the central computer occur interactively on a real time basis, correction and optimization of the weaving process at individual machines is possible, resulting in higher productivity and quality.
