The apparatus can further comprise a bushing comprising a sleeve having an outer surface and defining an inner bore. The inner bore of the sleeve can have an operative circumference. The sleeve comprises a bladder that is configured to expand radially upon receipt of a fluid to reduce the operative circumference of the inner bore. The bushing can further comprise a flange extending radially outwardly from the sleeve. The flange defines a vessel containing fluid therein. The vessel is in fluid communication with the bladder of the sleeve. The bushing comprises an actuator that is configured to cause the fluid from the vessel of the flange to flow into the bladder of the sleeve. An alignment feature can be configured to rotationally position the roller relative to the bushing.

JOINTED STRAND AND METHOD OF PRODUCING THE SAME

A jointed strand includes a superposed portion in which a first strand end in which fibers are oriented in one direction and a second strand end in which fibers are oriented in one direction are superposed; and a joint portion in which fibers of the first strand and the second strand are interlaced at the superposed portion, wherein the joint portion has a slit extending in a fiber orientation direction and a joint spot adjacent to the slit at one location or a plurality of locations aligned in a direction orthogonal to the fiber orientation direction, and monofilaments of the first strand and the second strand are interlaced at the joint spot.

Yarn tension and breakage sensor system
11242216 · 2022-02-08 ·

A yarn monitoring system for textile machine uses sensors to indicate yarn over tensioning and breakage. The sensors are contained within, or adjacent to, eyelets and monitor, sending signals to the controller, the speed of the yarn. The eyelets, each with a sensor, are within a body that also contains a circuit board which is in constant communication with the eyelets and software contained within a controller. The controller, in turn, is in constant communication with the textile machine. The software is preprogrammed by a user with an acceptable signal range for passage of the yarn past the sensors and a predetermined time period for the signal to remain outside the acceptable signal range. To prevent unnecessary shut down of the textile machine, the software averages the signal and, when the averaged signal remains out of the acceptable signal range for the preprogrammed time initiates communication to the textile machine.

Unwinding of materials

There is provide a process for unwinding material from a spool (2) wherein the angle (Θ) of take off at the first contact point (4) for the unwind is always in the range 0±20°, and wherein the first contact point (4) for the unwind is no more than 600 mm from the axis (3) of rotation of the spool (2). There is also provided an apparatus for the unwinding of material from a spool (2) comprising an axis (3) upon which a spool (2) may be rotatably mounted and a static first contact point (4) for the unwound material positioned no more than 600 mm from the centre of the axis (3), wherein the angle (Θ) of take off at the first contact point (4) for the unwind is always in the range 0±20°.

Beam Brake System And Method

A system for braking rotational movement of at least one beam is disclosed. The system can comprise a frame and at least one beam rotatably supported on the frame. Each beam of the at least one beam can comprise at least one sheave groove on at least one longitudinal end. A rope can have a first end and a second end. Each of the first end and second end can be fixedly coupled to the frame. The rope can be received within a portion of at least one of the at least one sheave groove of each beam. A tensioning assembly can be configured to selectively cause a predetermined braking tension in the rope.

METHOD AND DEVICE FOR FEEDING ELASTIC THREADS IN A PLANT AND PROCESS FOR THE PRODUCTION OF LAYERED COMPOSITE ARTICLES

A method for feeding elastic threads in a process for the production of layered composite articles includes: feeding at least one elastic thread along a path extending from a reel of an elastic thread up to a joining zone with at least one web material. Feeding the elastic thread along the above path includes: giving the elastic thread a first percentage elongation along a first section of the path extending between the reel and a control zone; giving the elastic thread a second percentage elongation along a second section of the path extending between the control zone and the joining zone. The second percentage elongation is greater than the first percentage elongation and a length of the first section is greater than a length of the second section.

Methods of separating carbon fiber tows
11220025 · 2022-01-11 · ·

A method of separating carbon fiber tows. The method includes separating two or more first carbon fiber tows from a first tow band onto a second elevation to form two or more second carbon fiber tows from a second tow band. The two or more second carbon fiber tows from the second tow band leave gaps next to first adjacent tows of the two or more first carbon fiber tows remaining from the first tow band after the separating step. The first adjacent tows from the first tow band leave gaps next to second adjacent tows of the two or more second carbon fiber tows from the second tow band.

Method for spreading a tow of textile non-braided filaments, preferably chemical or inorganic filaments
11401630 · 2022-08-02 · ·

A method for spreading a tow of textile non-braided filaments, preferably chemical or inorganic fibres comprises providing a tow of textile non-braided filaments extending along its own main direction and having a section transverse to the main direction with a predetermined thickness and a predetermined width, feeding the tow along a travel path and spreading the tow in order to increase its width and reduce its thickness, defining a spread tow. The step of spreading the tow includes immersing the tow in a bath and generating in the bath a sequence of transverse waves crossing the tow transversely to the main direction in order to separate and place the individual filaments side by side, thereby spreading the tow, wherein the tow entering the bath and/or the spread tow extracted from the bath is/are unsized.
