Publication number: 20190352809Abstract: 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.Type: ApplicationFiled: March 27, 2018Publication date: November 21, 2019Inventor: Marco ROVELLINI

Publication number: 20190352813Abstract: A weaving apparatus comprising a shuttleless loom with a weft insertion device. A transfer device and retaining disc are connected to the weft insertion device such that the retaining disc holds the weft fiber in a fixed orientation as it traverses through the shed of the loom. A plurality of sensors which are part of a microcircuit are mounted on the retaining disc for measurement of the weft fiber's position. A signaling circuit is mounted on the shuttleless loom and an electrical connector is connected to the signaling circuit to allow for external monitoring or display of the weft fiber's position. The measurements from the plurality of sensors are communicated through the electrical connector to an external device such that the position and orientation of the weft fiber can be monitored or displayed as the weft insertion device travels through the shuttleless loom.Type: ApplicationFiled: May 13, 2019Publication date: November 21, 2019Inventor: James Tolle

Publication number: 20190352816Abstract: An automated unspooling mechanism capable of dispensing of knitting material strands in a dynamically-controlled tension on a knitting machine. An unspooling device is configured to sense the tension of a strand fed to the knitting machine, and responsively adjust the strand deployment speed to avoid too little or too much strand dispensing without interrupting the knitting process. The unspooling device includes a variable motor drive that can rotate the strand package in various speeds, and a spring arm trigger that can sense the current tension of the dispensed material. The spring arm trigger can vary its arm position based on the sensed tension. The arm position is then processed and converted to a signal to vary the motor speed. Therefore, the deployment speed of the strands can be dynamically controlled based on a sensed tension of feeding the strand.Type: ApplicationFiled: May 15, 2019Publication date: November 21, 2019Inventors: Bruce Huffa, Concetta Maria Huffa
