Description

The proposed tissue binder is intended to enable the fabrication of a fabric stitching operation much faster than with ordinary sewing machines, due to the large number of simultaneously working needles instead of one in the proposed binder.

The present invention can be applied mainly in textile production conditions for cross-linking pieces of goods, for example, when operating non-woven and other dyeing and printing plants, on which the fabric entering Mamniij with a continuous web gradually winds off a roll and when one roll ends, You have to stop the car to sew the ends of the fabric of the old and the new roll.

In FIG. 1 shows a front view and part of a section of a folder; FIG. 2 is a top view and part of the section; FIG. 3-cross section; FIG. 4, 5 details; FIG. 6 different loops; FIG. 7 is a diagram of the various moments of the position of the needles and knots of the tillers II of FIG. 8, 9-part.

The binder has two parallel strips a (Figs. 1, 2, 3) with a series of needles 6 attached to them (Figs. 1, 2, 3). Each needle b (Fig. 4) consists of two spring plates g and w. screwed to either side a. Both parts of the needle are pressed to each other by the lower ends, forming the eyelet, at the top of the same flow-rate. Such a device of needles makes it possible to charge them with the thread of the coil g, without passing the end of the thread through the eyelet, since the thread perpendicular to the needle core enters the eyelet when lowering it between the halves of the needles towards the tip. If we continue this movement of the thread further, the latter leaves the eye, slipping through the slit between the halves of the needles. The described needle loading and unloading operations can be carried out due to the spring action of the HALF SIP needle, which, when passing through the thread, at the appropriate moment, slightly deviate from the initial position, forming the desired slot, which also contributes to the protrusion g on the plates, which serves holding the thread Against each of the needles, in a vertical direction there is a row of loop-traps (knotting knots) e (fig. 1,2,3), the purpose of which is to form nodules fastening both layers of fabric; The nodes of the gateways are equipped with the grips d (Fig. 5) for engaging the thread from the lower coil g. Drink is positioned on the props, which it moves when the knot is formed. The stitching fabric is laid on the table / and pressed against the plates d with the slits in the middle. To extend the thread in the area between every two needles (Figures 1, 2, 3}, a comb / g is used, the tooth of which has bulges. The handle p (Fig. 1. 2), which drives the machine, is fixed on the main axis, fitted with six cams, which set in motion between the vertical guides of the three pairs of frames (Figs. 1, 2), to which the needles with needles, the pressure plate and struts are attached. From the main axis, the movement is also transmitted to the nodes by means of a pair of gears for each knot is complete. To tighten the knot near the lower thread and cut the loop, The protrusions y are present on gears x (Fig. 7). Fig. 7 shows a diagram of the different positions of the knots of needles and needles in the course of action of the device. Each knot does not have an outer outline in the form of an open circular line. The transducer rotates one revolution. This movement is carried out in the guides with the help of two gears, which engage the locking knots of the subassemblies (Fig. 5), and at least one of the gears is in full motion. meshed with knots by the user. FIG. Figure 7 shows the sequential moments of the needle and the knots, and the effect of the knots is considered here, starting from the moment when the loop is already captured by it. The lower end 3 of the loop 4 (position e of Fig. 7), which is attached to the claws of the d nodes, follows the movement of the claws, begins to describe a circular line. The bottom thread b, which lies on the supports e, by which time they have moved to the lowest position, is at the level of the middle of the loop. Thus, the meeting, the resistance of the lower thread, the loop is bent around this thread at the point 7 of the bend (position e of fig. 7). Simultaneously with this, the forward pointed end of 8 knots e passes into the gap between the halves 9 and 10 of the loop, and after it the whole path goes along the whole knot of the receiver along with the hooks d, with the end of the loop on them. the thread, with the help of supports, gradually moves upwards (position I, d of fig: 7) so that by the end of the complete turn of the knots, it is pressed against the lower surface of the fabric (position h of Fig. 7). The result of the operations described is a nodule 11, which is finally tightened by the knife blade (protrusion) y, mounted on gear x. The strength of the knot is due, firstly, to the fact that its shank 13 is held by friction, being clamped at its beginning between the halves of the loop and the lower thread, and, secondly, by that. that the resistance of the fabric through which the loops of the upper thread are stretched does not allow the halves of the loop to move apart in the place where the knot is formed from it. At the beginning of the rotation of the handle p (Fig. 1, 2), which activates the mechanism, the nodes of the gate remain motionless, while the needles descend from the extreme upper to the lowest position, pulling along the path the cloth. This is the end of the working movement of the needles, because at the moment following the transition of the needles to the lowest position, the nodes of the needle begin to rotate and pick up the ends of the loops, the needles, freed from the thread, rise up, returning to their original position ; the required movement of the bars a with needles b is carried out with the help of eccentrics of the corresponding outline, sitting on the main shaft, moving the bars o (fig. 1) up and down. initially stationary (until the needles move to the lowest position), and then moving into rotation, is achieved with the help of the notched teeth 14 fixed on the main shaft, which have an incomplete number of teeth but with a circumference so that the handle at the beginning of movement actuates only eccentrics (cams) and only at the required moment did the coupling of the incomplete teeth to the gear 18 (Figs. 3 and 8) transmitting the rotation of the knot knots. As the knots knot rotated, the lower joint action of the needles a and knots At the lowering of the needles, at the beginning of the binder, the tip of each of them falls into the slot 15 (Fig. 9) of the knots and descends until the upper edge of the needle's eye appears slightly below the level, the grab knots are stopped. Following this, the nodes of the zatel come into rotation, at which the grippers d move towards the needle and are located on both sides of the needle, tightly grasping its stem 16 (Fig. 9), with the end of the loop 3 being put on the grips; then the needles rise up, and the netles remain on the grips, as the latter hold, their ends. The release of the loops of the upper thread from the needles becomes possible due to the arrangement of the needles, the core of which is cut in the longitudinal direction into two halves, as indicated above. The subject of the patent. 1.
