558575 A7 V. Description of the invention (The present invention relates to a multi-color weft yarn selection device of a weaving machine, which is connected to the second of the weaving machine ==, and controls the weft yarns of different colors with each weft control lever. "Ⅱ = yarn The joystick can be shifted to select a specific color weft yarn: Move to a specific position, and weave with a weft crochet needle and a tongue needle. 'Ya is convenient for the operator of multi-color weft yarn selection. The different design methods of the manufacturers of warp and weft knitting machines are based on the weaving method: There are different requirements for the production of ° σ, and there are many different types of weaving machines; the most basic ribbon weaving machines are only It is a single-color "cloth two". For: when color changes occur, warp yarns of different colors can be used or: yarns can be used to weave different types of products. If warps of different colors are used, different colors can be woven. In the longitudinal stripe, if weaving yarns of different colors are blended, weaves can be woven with a check pattern, and we can make more beautiful tape products. In the existing technology, weft changing operation It is a very difficult job.'Some manufacturers draw specific threads from warp yarns to make wefts. However, when this operation is performed with a traditional ribbon loom, it must be done with a repeating operation chain with a flower plate. Choose, if there are i 2 0 needles in every change cycle, the operation chain needs to have 20 knots, and at the selected position, the link chain will push the dial to act on the dial to choose the thread change.

Although this kind of design can achieve the effect of design and long weight, the thread head will melt and form a J block at the edge of the tape after melting. Even the tape is used for book tape or daily necessities. The right-handed object used as a personal accessory will cause friction to the skin, t, the user's discomfort, and the heat-melting method for the thread treatment, but also face strength ... and preparation and heating temperature control, etc. It is indeed a problem that needs to be solved in related industries. The main purpose is to provide a multi-color weft yarn of the weaving machine. The method is that the warp yarn at the weaving position of the weaving machine is pulled with weft yarns of different colors at the weaving position. After the stroke, one of the multiple weft yarns is selected as the weft yarn for the next wefting stroke to be knitted with the warp banknote. The remaining weft yarns will be treated in the next weaving stroke (please read the precautions on the back before filling this page) )
