P424Method of joining two edges of knitted product

Oblast'techniky

The invention relates to a method of joining two edges of a knitted tubular article, for example by chaining, i.e., after the article is knitted, its tip is joined by splicing.

I.tfl · .X,

BACKGROUND OF THE INVENTION The joining of two socks which are below the closed level

For example, IT document FI93A128 discloses a method for edge knitting a tubular article, for example, comprising an initial step of making the article by a circular machine starting from the elastic bead and ending on the side of the tip that is left open, the method of the present invention including further working steps: positioning the last-formed stitches of the first half-order on the knitting needle of the second half-order by rotating 180 'about the diameter axis of the needle cylinder so that the pairs of the stitches of the first and second half-order are in the retained position on the needles of the second half-order; - lowering the needles of the second half-row at open sinkers, thereby moving the stitches of the first and second half-row to the level that lies on the sinkers; raising the needles of the second half-row at the sinkers, whereby the corresponding pairs of stitches of the first and second half-row are held by the sinkers at a given position relative to the stems of the respective needles; further lifting the needles of the second half-order with open sinkers until all the corresponding pairs of stitches have reached the working level of the transferring device of the first half-order, thereby retaining the stitches of said device; lowering the needles of the second half-row, thereby releasing the article from the knitting needles, and the stitches of the first and second half-orders are caught by said transfer device;

placing the article with the loops so removed at a given distance from the knitting roller; positioning the transferred stitches so that they are angularly equidistant, with the circular pitch being predetermined according to the desired degree of fineness of the chaining;

- trimming the matching pairs of stitches so disposed and, after completion of the chaining process, one or more knots are made to close the chain; - cutting the chain strand; - releasing the thus coupled pairs of stitches of the first and second semiranks, thereby allowing the article in its final state to be removed face-to-face.

It should be emphasized that the loop should be retained when mounted on the reed needle and be level between the needle hook and the free end of the reed, with the reed fully open.

The aforementioned working method requires that the aforementioned chaining method be carried out with a sock whose face side faces outwards. This requires extra carefulness and precision when linking, as the linking takes place on the outside of the product tip. In addition, after the chain closure knots have been made, it is necessary to introduce the end-length chain thread into the article, thereby preventing it from being seen in the finished article.

SUMMARY OF THE INVENTION

The main object of the present invention is to overcome the above drawbacks and to provide a method which simplifies joining the toe of a knitted tubular article, in particular of a sock type, which method allows to obtain a finished product with good quality.

According to the present invention, the result has been achieved by adopting a method comprising the initial step of manufacturing a knitted tubular sock-like product by a circular machine starting from the elastic bead and ending on that side of the toe that is left open, the method comprising the further steps of:

- moving the plate away from the knitting head of the machine;

lifting the knitting needles with the sinkers closed so that the eyelet of the last knit row, i. the socks of the sock toe have been retained by said sinkers in a position corresponding to the area of removal of the respective needles;

further raising said needles with the sinkers open so that the stitches of the last row are positioned above the sinker noses;

- removing the individual said stitches from the respective needles and retaining them;

- lowering the knitting needles so that the knitting head of the machine is cleaned from the toe of the sock;

moving the sock with the retained loops of the last row out of the knitting head of the machine to a given distance from the knitting head;

turning the sock backward so that it is inverted and the elastic bead is at a suitable distance from the toe;

- transferring the stitches of the first half-order to the corresponding stitches of the second half-order by overturning them 180 'around the diameter axis of the circumference defined by the last knit row of stitches so that all the stitches of the first half-order are coaxial and coaxial adjacent stitches belonging to one edge of the product tip;

placing the stitches of the first and second semicircles so connected along the peripheral; arc at constant angular distances, the pitch of which is selected according to the desired fineness of the chaining;

splicing the pairs of stitches thus positioned and, after the chaining process has been completed, making one or more knots of the heat-sealing chains; - · · · -

- cutting off the chain strand;

- inverting the product with the tip cut in such a way with the face side out, i.e. to the final state and removing the product.

In particular, the advantages of the present invention reside in the fact that the aforementioned can be made automatically

trimming without interrupting the operation of the knitting machine and with the sock in the inverted state (reverse side outward) so that it is possible to perform the chaining operations inside the product and eliminate the operation of the chain strand of the final length after cutting; that said cleavage can be carried out with any suitable degree of fineness so as to obtain an end product of optimum quality.

moving the plate 10 away from the knitting head of the machine 1 (FIG. 2);

lifting the knitting needles 2 with the sinkers 3 closed so that the stitches 4 of the last knit row, i. the eyelets at the toe of the sock 1 have been retained by said sinkers in a position corresponding to the area from which the respective needles 2 are removed (Figs. 3 and 4);

further lifting said needles 2 with the sinkers open, thereby moving the stitches 4 above the nose 30 of the sinkers 3 (FIG. 5);

removing said individual stitches 4 from the respective needles 2 and retaining said stitches (Figs. 6 to 8);

lowering the needles 2, thereby releasing the toe 51 of the sock 5 from the knitting head of the machine X (FIG. 9);

- transferring the sock 5 with the stitched eyes 4 of the toe 51 from the knitting head of the machine X to a given distance from that head (FIG. 10);

turning the sock 5 inside with the elastic skirt 50 then above the toe 51 (Figs. 11 and 12);

- transfer of stitches 4 of the first half-row x. to the corresponding stitches 4 of the second half-row by inverting them 180 ° around the diameter axis of the circumference indicated by the last knit row of stitches so that all stitches 4 of the first half-row x are adjacent to the corresponding stitches 4 of the second half-row y. and was coaxial with these guides (Fig. 13);

- positioning the stitches of said first and of said second half-row (x, v) so connected along a circumferential arc at constant angular distances whose angular pitch is selected according to the desired fineness of the chaining;

chaining the pairs of stitches 4 thus positioned and, after the chaining is completed, making one or more knots closing the chain (FIG. 14);

- cutting the chain thread;

- bringing the sock 5 with the toe-cut toe 51 back in a state in which the face side faces outwards, i. to the final state and removing the sock (fig. 15).

According to the present invention, the stitches 4 of the first semi-row x can be advantageously transmitted. to the corresponding stitches 4 of the second half-row γ after placing all said stitches 4 of the last row on the respective device 6, which transmits them from the knitting head of the machine 1 and which then inverts the stitches 4 of the first half-row x.

Moreover, before said chaining, it is advantageous to transfer the stitches 4 to the front of the chaining ridges 7. In case the number of stitches 4 of the first semi-row x. differs from the number of stitches 4 of the second semi-row y, stitches 4 which will be excluded from said joining, but will preferably be aligned.

According to the present invention and with reference to FIGS. 10 to 15 of the accompanying drawings, turning the inner side out and then turning the sock 5 face side out is preferably accomplished by a pneumatic invert hose 8 coaxial with the sock 5, and this reciprocating preset movement. in the direction of the longitudinal axis (a-a) of the hose, it is preferably designed to allow the hose to be inserted into the sock 5 on the side of its toe-cutting tip 51, i. catching the edge of the elastic bead 50 and then inverting the sock

5. with the elastic bead 50 thus engaged.

The same hose 8 is to control the suction of the finished sock 5 by acting on its toe 51 so as to allow simultaneous turning of the sock 5 face side and removal of the sock 5 in the final state (see FIG. 15).

All design details can practically vary in shape, dimensions, location of parts of the materials without deviating from the solution, and while still remaining within the protection afforded to the present invention.
