Fabric support and a weaving machine using the support, in which the fabric support () includes several supporting elements () which can be arranged next to one another and a profiled section () which is supported by the supporting elements () and includes a guide surface () for a fabric ().

Fabric support for a weaving machine

A valve () is described comprising: a housing () having a fluid inlet for () receiving a flow of compressed fluid and a fluid outlet (); a flow duct () movably mounted with respect to the housing, the duct () having a fluid inlet () for receiving a flow of compressed fluid and a fluid outlet (), the fluid outlet being positioned around at least a part of the circumference of the duct and being dimensioned to provide a different flow rate at different sections or positions around the circumference of the duct; the fluid outlet of the housing being alignable with a portion of the fluid outlet of the duct to provide a flow rate related to the relative position of the portion of the fluid outlet of the duct and the fluid outlet of the housing; and, a drive element () for moving, e.g. rotating, the duct with respect to the housing such that a desired portion of the fluid outlet of the duct aligns with the fluid outlet of the housing. The valve may operate as a so-called throttle valve. It is an advantage that the valve is quickly movable into a desired relative position in order to regulate fluid flow through the valve. The valve is designed to have a long operational lifetime as, even if the outer surface of the duct wears, the outlet will not substantially change in size and the throttling effect will remain substantially the same.

A thread stretching device for a weaving machine, especially an air jet weaving machine, includes a thread gripper () for gripping the weft thread () as a device for stretching a weft thread inserted into a shed. A mechanism () for deflecting the weft thread is arranged upstream of the thread gripper, relative to the weft thread transport direction.

Device and method for stretching

Blowing nozzle for supporting a weft thread in a weaving machine, provided with a flow-through canalisation () for a fluid tracing a bend () near the free end of the blowing nozzle () to subsequently flow into the environment via at least one outlet opening (), wherein a jet pipe () is formed in this flow-through canalisation (), and the jet pipe () is integrated in the bend ().

Method for optimizing a textile production process, which consists in manufacturing a fabric () on a weaving machine (), characterized in that characteristics of the fabric () and/or fabric-determining elements are visualized on a machine screen by means of at least one image.

Method for optimizing a textile production process and devices applying this method

Apparatus monitoring and/or adjusting tensile force in a yarn () including at least three consecutive yarn deflecting elements () of which the central deflecting element () is displaceably held by a retention device () that is supported in such a way that the motion and/or position of the deflecting element () is substantially a function only of the tensile force F1 in one yarn segment, such segment being situated between the displaceable deflecting element () and only one of the two neighboring deflecting elements (or).

Device for detecting and/or adjusting a tensile force in a yarn

A thread clamp for a weaving machine includes a clamp having at least two clamping parts between which a thread may be clamped and an actuator arranged to move the clamping parts between clamping and unclamped positions. The actuator is arranged to operate the clamp so that it moves at least in one direction by a negative fluid pressure. The actuator may be formed as a small piston that may be actuated both by positive pressure and negative pressure to move the clamp between clamping and unclamped positions.

Thread clamp for a weaving machine

A device for inserting weft threads in an airjet weaving machine including at least one main blower and a respective thread clamp associated with the main blower. The thread clamp is constituted of an element configured in a modular form. Such modular form enables several such elements to be assembled in a modular configuration, including one on top of another. Pneumatically actuated elements are used to engage and disengage the thread clamps whereby the thread clamps may be engaged or disengaged by pressure and vacuum supplied through a single supply conduit. A method for inserting weft threads in the shed of an airjet weaving machine includes holding each weft thread at least temporarily in a thread clamp that moves with the sley of the weaving machine and using a thread tensioner outside the shed at a location between the thread supply and the thread clamp. A further method of inserting weft threads includes supplying the main blower temporarily with a lower pressure before insertion of the weft thread by the main blower when the thread clamp holding the thread is opened.

A weaving machine, in particular an airjet loom, which is fitted with a system () for cutting a filling thread ('), which is being held ready for filling insertion, from a filling () already beaten into a fabric (), wherein the system () includes a laser.

Power loom with a device for cutting off a woof thread

A weaving machine, in particular an airjet loom, which is fitted with a system ( ) for cutting a filling thread ( ), which is being held ready for filling insertion, from a filling ( ) already beaten into a fabric ( ), wherein said system ( ) includes a laser.

The invention relates to an airjet weaving-machine auxiliary nozzle ( ) in the form of a hollow needle ( ) having a closed tip ( ), the auxiliary nozzle having a bulge at its distal end extending towards one side only of the nozzle centerline, such that the bulge extends towards a reed of a weaving machine in which the nozzle is installed relative to the centerline.

Auxiliary nozzle for a weaving machine

A loom reed including upper and lower bars which support reed dents and extend along the length of the reed is provided with a connecting device for connecting a brace to the upper bar to restrict longitudinal movement of the reed during loom operation.

Reed with bracing arrangement

A reed ( ) for a weaving machine. The reed includes juxtaposed reed dents ( ), the ends of which are held in a lower profiled bar ( ) and in an upper profiled bar ( ). The reed dents in at least a sub-segment projecting from the lower profiled bar have a width of about 6 mm and in an upper segment exhibit a width of about 4 mm.

Reed and reed dent for weaving machines

An elongated connecting blade or bracing element (,) is used to fix a reed (,) to a batten beam (,). The blade runs substantially in the longitudinal direction (A) of the reed (,) and is connected to the upper profiled bar (,) of the reed (,) and to the batten beam (,) while being spaced away from the reed (,), in order to reduce a displacement of the reed (,) in the longitudinal direction (A).

Device for securing a weaving reed to a batten

A weaving machine air supply block (,). The air supply block includes conduits (,through,) and switched and/or adjusted valves (,) driven by valve drives (,) configured between an inlet (,) and an outlet (,). The device provides two outlets (,) at one longitudinal side (,) of a substantially right parallelipipedic housing, each outlet being associated with its own valves (,).
