Description

Method of joining two edges of knitted product

Technical field

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.

BACKGROUND OF THE INVENTION

It is known from IT document FI93A128 to join two edges of a knitted tubular article, e.g. a sock, where the article is knitted by a circular knitting machine, starting at the elastic bead and ending at the side of the toe that is left open. The method of said document comprises the steps of: placing the last knitted stitches of the first half-row on the knitting needles of the second half-row of the twists so that they rotate 180 'around the diameter axis of the needle cylinder; partial course, needles of the second partial course starts at the open sinkers, thereby loops ^- the first and second partial moved to a level which lies below the level of the sinkers, and the needles of the second partial course raise the sinkers being closed, whereby the corresponding pairs of stitches of first and second partial retaining hooks at a given position with respect to the stems of the respective needles, the needles of the second semi-row are further raised with the sinkers open until all corresponding pairs of stitches have reached the working level of the transfer device of the first semi-row, thereby stitching the stitches. detaining said device. Then the needles of the second half-row are lowered to release the article from the knitting needles and the stitches of the first and second half-row are grasped by said transfer device, then the article is positioned with the stitches so removed at a given distance from the knitting roller. equally spaced so that the circular pitch can be pre-set according to the desired degree of fineness of the chaining. Next, the matching pairs of stitches disposed in this manner are truncated, and after completion of the chaining process one or more knots are formed which close the chain. The chain thread is then cut and the loosened pairs of stitches of the first and second semiranks are released, thereby ensuring that the article is removed in its final state by the face side.

It should be emphasized that the eyelet 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-mentioned drawbacks and to present a method that simplifies coupling

The tip of a knitted tubular article of a particular sock type, the method making it possible to obtain a finished product of good quality.

According to the present invention, the method comprises an initial step of manufacturing a knitted tubular sock-like product on a circular machine, starting with the elastic bead and ending on that side of the toe that is left open, after knitting the sock needles with closed sinkers so that the stitches of the last knit row, ie the stitches of the end portion of the sock toe, hold the sinkers in a position that corresponds to the area of removal of the respective knitting needles; , and after removal of the individual stitches from the respective knitting needles, the individual stitches are retained, after which the knitting needles are released to release the sock toe from the knitting head of the circular machine, whereupon the sock is retained swarms to a given distance from this knitting head, and then the sock is turned internally outward with the back side facing out and the elastic bead positioned above the tip, then the stitches of the first half-order are transferred to the corresponding stitches of the second half-order by 180 ° inversion around the diameter axis a circumference defined by the last knitted row of stitches so that all stitches of the first half-row are adjacent to and aligned with the corresponding stitches of the second half-row, after which the stitches of the first half-row and second half-row are the spacing is selected according to the desired fineness of the chaining, after which the pairs of stitches thus positioned are trimmed, after completion of the chaining process one or more knots closing the chain are made, and then the chaining thread and sock are cut off pussy turns back to face outward, ie. the final state, and eventually closed-toe sock removed.

According to a preferred embodiment, the stitches of the first semi-row are transferred to the corresponding stitches of the second semi-row after placing all the stitches of the last semi-row on the respective device, removing the stitches from the knitting head of the circular machine and subsequently inverting the stitches.

According to a further preferred embodiment, the eyelets are transferred to the front of the chaining ridges before the chaining.

In particular, the advantages of the present invention reside in the fact that it is possible to automatically produce said splicing without interrupting the operation of the knitting machine and with the sock in the inverted state (back side out) so that chaining operations can be performed inside the product. after cutting it off. Said screening may be carried out by any suitable degree of fineness so as to obtain an end product of optimum quality.

And FIG. 13

After being chained with its trimmed toe after removal with the face side, it is limited to its essential nature and with reference to the accompanying drawings, a method of chaining a sock toe according to the present invention, comprising an initial step of fabricating a knitted tubular article. on that side of the tip 51 which is left open, using the circular knitting machine 1, comprises the following working steps: the plate 10 moves away from the knitting head of the machine (FIG. 2), and the knitting needles 2 are lifted with the sinkers 3 closed; so that the stitches of the 4th last knit row, ie. the eyelets at the toe of the sock 5 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). The needles 2 are raised even further with the sinkers open, whereby the stitches 4 move over the nose 30 of the sinkers 3 (FIG. 5).

The individual stitches 4 are then removed from the respective needles and retained (FIGS. 6 to 8).

-3GB 281466 B6

The needles 2 are then lowered, releasing the toe 51 of the sock 5 from the knitting head of the machine 1 (FIG. 9).

The sock 5 with the eyelets 4 so retained is transferred from the knitting head of the machine 1 to a given distance from the head (FIG. 10).

Then, the sock 5 is turned internally outward so that the elastic skirt 50 is then above the toe 51 (Figs. 11 and 12).

The stitches 4 of the first half-order x are transferred to the corresponding stitches 4 of the second half-order y by inverting 180 ° around the diameter axis of the circumference indicated by the last knitted row of stitches so that all stitches 4 of the first half-order x are next to the corresponding stitches 4 of the second half-order y (Fig. 13). In this way, the stitches of the first and second semiranks (x, y) connected are positioned along the circumferential arc at constant angular distances, the angular pitch of which is selected according to the desired fineness of the chaining.

Then, the pairs of stitches 4 thus arranged are aligned and one or more knots closing the chain are made after the chaining is completed (FIG. 14).

The chain filament is cut off, and the sock 5 with the so-cut toe 51 is turned back to a state in which the face side is facing out, i.e. to the final state, and the sock is removed (FIG. 15).

According to the present invention, the stitches 4 of the first half-row x can advantageously be transferred to the corresponding stitches 4 of the second half-row y after placing all said stitches 4 of the last row on the respective device 6 which transfers them from the knitting head of the machine 1.

Moreover, prior to said chaining, the stitches 4 can advantageously be transferred to the front of the chaining combs. If the number of stitches 4 of the first semi-row x is different from the number of stitches 4 of the second semi-row y, the stitches 4 which will be excluded from said joining will nevertheless preferably be aligned.

According to the present invention and with reference to Figs. 10 to 15 of the accompanying drawings, turning the inner side outward 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 longitudinal direction. Preferably, the hose axis (aa) is provided to allow the hose to be inserted into the sock 5 on the side of its toe 51 to align, i.e., engage the edge of the elastic bead 50 and then invert 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 the sock 5 to be inverted simultaneously and to remove the sock 5 in its final state (see Fig. 15).

All design details can vary practically in terms of shape dimensions, location of parts and nature of materials used,

Without departing from the nature of the solution adopted, the solution still remains within the protection limits of the present invention.
