Description

"Ftn.fc

The invention relates to the textile industry, in particular to the shedding mechanisms, and can be used in the production of multi-layered fabric with specialized protrusions.

The purpose of the invention is the expansion of technological capabilities by turning off the yarn warp from interlacing.

FIG. 1 shows a heald mechanism, general view; Figure 2 is the same when the warp yarns are turned off from the weave, the Remizoup mechanism consists of a group of rollers 1, whose axis is located fc vertical guides 2 and has the ability to move in them a group of blocks 3 and a group of rollers 4 fixed on the frame. The blocks 3 are connected to cranes 5 of the casing carriage by flexible couplings 6, the axis of the roller group 1 is connected by two flexible couplings 7 through two additional rollers 8 to two cranes 9 located on different edges of the carriage, the additional rollers 8 are fixed on the ama. Each remix from the set is made va of two frames 10 and 11 with galev. The shim frame 10 is connected by a flexible link 12 through roller 4 to block 3, and the frame 11 is connected to the same Olock 3 by flexible link 13 via roller 1,

The mechanism works as follows.

i Getting movement from crane 5 through Ј to 6, block 3 rotates around its axis and through connections 12 and 13, thrown over the eolics 4 and 1. It lifts the hem, composing from frames 10 and 11, at the same time he takes its top position, shown in figure 1 by the dashed line. If the crane 5 does not move in the carriage, the shroud remains at the lower level.

Thus, all the shafts from the set occupy an upper or lower position in accordance with the weaving pattern. A shed is formed across the entire width of the weaving machine into which the weft is laid, and the fabric is accumulated over the entire width of the dressing. After the development of a specific tissue site, a transition is made to the formation of a tissue site with a profile protrusion. Cranes 9 connected by flexible connections 7 through additional rollers 8 to the axis of the group of rollers are deflected and thereby raise the group of rollers 1 in vertical guides 2. Since links 13 are connected through these rollers 1 connected to frames 11 of shafts, then these frames 11 rise to the top position. The frames 10 remain at the lower level. Each set shim is set to the position shown in Figure 2, in which the frames 10 of all shims are

below, and the frame 11 of all shafts is at the top. Further, the process of forming a section of fabric with a profile protrusion proceeds in the same way as in the case without a protrusion. Remizki occupy an upper or lower position in accordance with the weaving pattern. If the shroud is at the bottom, the frame 10 is in the lower position, and the frame 11 is in the upper position. If the shim is at the top, 0, then the frame 10 takes the upper position, and the frame 11 rises above the top position to the height of the throat. This position is shown in figure 2 by the dashed line.

Thus, only those warp threads, which are punched into the heel frame 10, take part in the formation of fabric 5, since the nigars of the warp, which were picked into the helix frame 11, are always in the upper branch of the throat or even higher and are not earned in fabric. Since the part of the warp threads is not earned in the fabric, and the other part is earned, then the resulting woven fabric forms a profile protrusion formed by weaving the weft threads and those warp threads that draw into the fabric. After operating time, the tissue sections with the profile protrusion of the carriage cardboard gives the command to the cranes 9, which control the movement of the rollers 1, will lower and they will lower to the initial position shown in FIG. Further, the fabric is produced over the entire width of the dressing, as described and so on.

Thus, the proposed mechanism, in comparison with the known, allows 5 to obtain a multi-layered fabric with shaped protrusions with a simultaneous increase in productivity.
