摘要:
The optimum control conditions for a plurality of looms are simply estimated with use of a trial loom. Hereby, the plurality of the looms are operated under a centralized control method. The looms, even if they vary in their peculiar characteristics, can be effectively operated by correcting standard control data for controlling the looms in response to variations of the loom characteristics. The present contralized control method can save much labor and time to improve productivity of the looms, by properly eliminating elaborate trial weaving processes.

The present invention relates to a picking apparatus (1) in a rapier loom. The apparatus has gripping bodies (2, 3) beween a weft selection device and a yarn cutter (14). The gripping bodies (2, 3) are movable up and down. The gripping bodies (2, 3) selectively grip a plurality of weft yarns (9a, 9b) in accordance with a color pattern. One yarn cutter (14) cuts the weft yarn (9a or 9b) gripped by the gripping bodies (2 or 3) and severs the cut weft yarn (9a or 9b) from a woven cloth (9) after the weft yarn (9a or 9b) is picked. According to the present invention, neither catch cords nor extra length fringe nor a selvage cutter is needed.

Seersucker weaving method and a seersucker loom capable of carrying out the seersucker weaving method. When the puckering warp yarns (6) are divided to form a shed (5) in weaving a seersucker by the seersucker weaving method, the tension of the puckering warp yarns is maintained on a level below that of the tension of the ground warp yarns (2), and the puckering warp yarns are slackened positively at least during a slackening period from shed closing operation to beating-up operation for every turn of the main shaft (3) of the seersucker loom so that the tension thereof is reduced below a predetermined tension of the same during a period other than the slackening period to slacken portions of the puckering warp yarns near the cloth fell (5) sufficiently during beating-up operation in order that the puckering warp yarns can be puckered satisfactorily.

According to the present invention, a carbon-fiber preform for a carbon-fiber-reinforced plastic is formed from mutually intersecting warp and weft each of which including a carbon-fiber multifilament yarn. At least one of layer surfaces has fluff formed by cutting some of filaments of the carbon-fiber multifilament yarn, and a total fluff length of fluff formed on the warp and a total fluff length of fluff formed on the weft are not equal. The present invention provides a CFRP in which the delamination strength (interlaminar shear strength) is improved and that has a high strength.

A warp mending device (10) for drawing a mending yarn (22) unwound from a bobbin (21) to a slot (20) of a drop wire (4) and a mail (24) of a heddle (6) corresponding to a trailing edge (1a) and a leading edge (1b) of a broken warp (1) so that a loom is started and a positioning device (14) incorporated in the warp mending device (10) for positioning drawing means relative to the mail (24) of the heddle (6) corresponding to the broken warp (1) in a predtermined positional relationship therebetween when the warp (1) is broken. The warp mending device (10) comprises a yarn guide (11) having a yarn guide line (15) therein for guiding the mending yarn (22) between the drop wire (4) and the heddle (6) corresponding to the broken warp (1), a nozzle for generating an air current inside the yarn guide line (15), a yarn leading device (13) for drawing the mending yarn (22) unwound from a bobbin (21) into a slot (20) of a drop wire (4) or a mail (24) of a heddle (6) whichever is located at the upstream of the drawing direction and leading the thus drawn mending yarn (22) into an inlet of the yarn guide line (15), and a positioning device (14) for positioning the slot (20) of the drop wire (4) or the mail (24) of the heddle (6) whichever is located at the lownstream of the drawing direction relative to an outlet of the yarn guide line (15) with confronted relation.

A size viscosity controller for a slasher, for controlling the viscosity of the size (4) contained in the cavity box (3) of the slasher. The viscosity of the size (4) is maintained at a desired viscosity by controlling heat supply units (12, 13) on the basis of the deviation of te measured temperature of the size (4) from a desired temperature so that the size (4) is maintained at the desired temperature and, at the same time, regulating the concentration of the size (4) by supplying wet heat, such as steam or hot water, to the size (4) or heating the size (4) by dry heat, such as heat generated by an electric heater, to regulated the concentration of the size (4).
