Description

A method for manufacturing a tubular product having a gripping area by a circular hosiery knitting machine, and a tubular product obtained by the method METHOD}

The present invention relates to a method for providing a tubular article, in particular a hold-up stocking, having a grip region on the back side by a circular hosiery knitting machine and to a tubular article obtained by the method.

As is known, hold-up stockings have a band at their upper end adapted to grip the upper region of a user's thighs in order to achieve a stocking hold-up effect and avoid the use of suspenders.

Optionally, grip of the stocking on the user's skin is obtained simply by providing an elastic band that is knitted with a double welt at the top of the product and tightened around the user's thighs. This solution has the drawback that, due to the conical shape of the thigh, in use, the elastic band slips downwards and curls along the product to achieve insufficient gripping.

In other cases, an elastic band usually made of lace is used on the upper end of the product, and a silicone strip or a plurality of silicone strips are applied on the inner surface thereof, which has the effect of increasing the adhesion of these bands to the user's skin. The lowering of the band is different along the user's thigh.

Although this solution achieves a superior hold-up effect compared to the previous solution, often this effect is still insufficient to prevent the product from falling and curling during use. Moreover, the use of elastic bands coated with silicone significantly increases the manufacturing cost of such products.

It is an object of the present invention to devise a method which makes it possible to manufacture tubular products, in particular hold-up stockings, by a circular hosiery knitting machine by providing a gripping area on the back side of the product directly during production of the product by a circular hosiery knitting machine. It is to solve the above-mentioned problem.

Within this object, it is an object of the present invention to produce tubular articles, in particular hold-up stockings, which have a greater gripping effect than can be achieved with methods of known types while at the same time preventing curling of the article along the user's thigh. suggesting a way to make it possible.

It is a further object of the present invention to propose a method which makes it possible to manufacture articles, in particular hold-up stockings, at very competitive production costs.

A further object of the present invention is that it is not necessary to carry out structural modifications thereof, but which can be implemented on a circular hosiery knitting machine of the preferably single-cylinder type using electronic selection of a known type by simply performing a software modification which is simple to carry out. to suggest a way.

Another object of the present invention is to propose a method which makes it possible to manufacture a comfortable product.

These and other objects, which will become more apparent hereinafter, use a circular hosiery knitting machine having at least two feeds or drops, wherein at least one first feed is capable of dispensing a bare elastomer yarn, said feed an apparatus for selecting a needle such that some of the needles of the knitting machine are moved to pick up the yarn or yarns dispensed from, while other needles are excluded from picking up the yarn or yarns dispensed from the feed; and To move the needle to a “tuck” position or “drop” position to pick up the yarn or yarns dispensed by the feed, or from picking up the yarn or yarns dispensed from the feed. Gripping on the back side to provide a hold-up stocking in particular by a circular knitting machine, comprising a cam for actuating the needle to move the needle to a "miss" position to dislodge it A method for making a tubular article having a grip region, wherein in the first feed one or more needles of one or more adjacent groups of needles are moved to pick up and knit the bare elastomeric yarn while the one or more groups of needles are moved. the other needles of the "miss" position are constrained or moved to the "miss" position to be excluded from picking up the bare elastomeric yarn, and the needles of the one or more groups of needles are the yarn or yarn to be dispensed in a subsequent feed. Picking up the needles and operating in one or more of the subsequent feeds to form a knitting with at least the needles constrained to the "miss" position in the first feed.

The article obtained by the method according to the invention has on its backside a gripping area, said gripping area protruding on the backside of the article and floating of bare elastomeric yarns knitted together with the other yarns constituting the article formed by a part or bridle.

Further features and advantages of the present invention will become more apparent from the description of preferred, but non-exclusive embodiments of the process according to the invention, the product obtained by the process, illustrated by way of non-limiting example in the accompanying drawings.

2 is an enlarged partial cross-sectional view of a part of the product obtained by the method according to the invention;
3 is an enlarged detail of the product turned inside out with respect to the gripping area;
Fig. 4 is the same detail as Fig. 3, tensioned at right angles to the axis of the product;

With reference to the drawings, the method according to the invention comprises knitting a circular hosiery with two or more feeds or drops to provide a tubular article having a gripping area on the back side, in particular a hold-up stocking of the type shown in the drawings. a first feed of at least one of which is adapted to dispense the bare elastomeric yarn to needles of a knitting machine passing through the feed. The circular knitting machine used for carrying out the method according to the invention is equipped with an electronic needle selection device of the known type, which feeds or It makes it possible to select the yarn to be dispensed from the drop or the needles of the knitting machine which should be operated to pick up the yarns. Moreover, such knitting machines are adapted, in a manner known per se, to move the needle to pick up the yarn or yarns dispensed by the feed in the "tuck" position or the "drop" position, or to pick up the yarn or yarns dispensed from the feed. A needle actuation cam is provided to move the needle to the “miss” position to exclude it from picking up.

In this description, the expression "back side" of the product should be understood to mean the one side of the product to face the user's skin.

The circular hosiery knitting machine which can be used for carrying out the method according to the invention is obviously equipped with other elements and devices, such as sinkers, yarn feeders, etc., in a manner known per se.

More specifically, in the preferred hypothesis of using a single-cylinder circular hosiery knitting machine and manufacturing an article with a needle positioned within a needle cylinder positioned vertically on the axis, the pickup of the yarn or yarns by the needle in the “jaw” position is , to a level at which the tip or head of the needle is extracted upwardly by the sinker, but not high enough to allow the previously formed knitting loop or loops to slide under the latch of the corresponding needle. up to the level, by raising the needle by means of a corresponding actuating cam. In this way, upon subsequent lowering caused by the corresponding actuating cam, these needles do not knock on the previously formed loop or loops but form a new knitting loop, the previously formed loop or loops forming a new loop with the head or tip of the corresponding needle.

Pick-up of the yarn or yarns by the needle in the "drop" position is at a level sufficient to allow the previously formed loop or loops of knitting to slide under the latch of the needle by the corresponding actuating cam. This is done by raising the needle to a height level at which the tip or head of this needle is extracted upward by the sinker to pick up the yarn or yarns. In this way, upon subsequent descent caused by the corresponding actuating cam, these needles will form a new knitting loop that is knocked or dropped onto the previously formed loop or loops of knitting.

When the needle is in the “miss” position, the head or tip of the needle is positioned below the knockover plane of the sinker and holds the previously formed loop or loops of knitting. In this position, the needle cannot pick up the yarn or yarns dispensed from the corresponding feed and thus cannot form knitting.

In the method according to the invention, in the first feed, one or more needles of one or more adjacent groups of needles cause such one or more needles to pick up the bare elastomeric yarn, while the other needles of the group of needles are constrained in a "miss" position or It is moved for knitting, which is moved to a "miss" position to exclude it from picking up the bare elastomeric yarn. The needles in the group of needles are actuated in one or more subsequent feeds to pick up the yarn or yarns dispensed in those subsequent feeds, using needles constrained to or moved to the "miss" position, at least in the first feed, in the "miss" position. to form knitting.

Preferably, in the first feed, one or more needles operated to pick up bare elastomeric yarns are operated to pick up such yarns in a “jaw” position.

Alternatively, in the first feed, one or more needles actuated to pick up bare elastomeric yarns are actuated to pick up such yarns at a “drop” position.

Preferably, in one or more subsequent feeds, the needle that has picked up the bare elastomeric yarn in the first feed is operated to pick up the yarn or yarns dispensed by the one or more subsequent feeds in a “tuck” position.

Conveniently, after generating a predetermined number of rows of knitting by another needle in the group of needles, ie by a needle that does not pick up the bare elastomeric yarn in the first feed, the bare elastomeric yarn is picked up. A needle is actuated in one or more subsequent feeds to pick up the yarn or yarns dispensed by this feed at a "drop" position, and also to form a new knitting loop that drops a previously formed knitting loop that is bound to its head. will do

Without changing the fact that it is possible to use knitting machines with different numbers of feeds or drops, the method according to the invention is sequentially about the axis of the needle cylinders of the knitting machine along the direction of rotation of the needle cylinders with respect to the feeds or drops. It is preferably practiced by using a circular hosiery knitting machine with four feeds arranged.

Preferably, when it is desired to provide a circumferentially extending gripping area on the back side of the article, substantially all of the needles of the knitting machine are used which have divided the needles into a plurality of groups of needles, wherein each group of needles is one. Selected and actuated as described above for the above needle groups.

Each needle group preferably consists of 7 to 16 contiguous needles, and in the first feed from which the bare elastomeric yarn is dispensed, each needle group has a first selection between 1:6 and 1:15, i.e. the "tuck" causing actuation of one needle to pick up the bare elastomeric yarn at the "miss" position, and retention of between 6 and 15 multiple adjacent needles or rather subsequent needles (subsequently passing in the first feed) in the "miss" position. or according to the selection that causes passage.

Alternatively, each needle group may contain 8 to 17 adjacent needles, causing selection of needles in the first feed, i.e. actuation of two adjacent needles to pick up the bare elastomeric yarn in the “jaw” position. and the selection causing retention or passage of between 6 and 15 multiple adjacent needles or rather subsequent needles (subsequently passing in the first feed) in the "miss" position can be between 2:6 and 2:15. have.

In one or more subsequent feeds, preferably the second feed, each group of needles has one needle operative to pick up said yarn or yarns in said “tuck” position and said “drop” every two adjacent needles of said group of needles. 1:1 with one needle actuated to pick up the yarn or yarns in position, 2 adjacent needles actuated to pick up the yarn or yarns in the "tuck" position and every 4 adjacent needles in the group of needles 2:2 with two adjacent needles operative to pick up the yarn or yarns in the "drop" position, two adjacent needles operative to pick up the yarn or yarns in the "tuck" position and the group of needles 2:1 with one needle actuated to pick up the yarn or yarns in the "drop" position for every three adjacent needles, or one needle actuated to pick up the yarn or yarns in the "tuck" position; and is selected according to a second selection selected from 1:2 with two adjacent needles operative to pick up the yarn or yarns at the “drop” position for every three adjacent needles of the group of needles.

In this second feed, the needle that picked up the bare elastomeric yarn in the first feed belongs to the needle that is moved to pick up and knit the yarn or yarns in the “tuck” position.

It should be noted that, in the transition from the first feed to the second feed, the needle that picked up the bare elastomeric yarn in the first feed at the “jaw” position is not lowered. This is achieved by deactivating the lowering cam of the needle at the first feed. Due to the fact that these needles are not lowered, in the second feed these needles pick up the yarn or yarns dispensed by this feed at a position slightly higher than the "jaw" position and thus the previously formed stitch on that stem. Drop (stitch).

In the second feed, the needle is lowered after picking up the yarn or yarns to form a new knitting loop.

In the third feed, the needle that picked up the bare elastomeric yarn in the first feed is re-actuated in the “jaw” position to pick up the yarn or yarns dispensed by this feed during a preset number of revolutions of the needle cylinder, while the needle The other needles in the group operate in a “drop” position to pick up the yarn or yarns dispensed from this third feed to form a knocking knitting on a previously formed knitting loop. After this predetermined number of turns, the needle that picks up the bare elastomeric yarn from the first feed may orient the yarn in the “drop” position to form a new knitting loop that drops the previously formed and constrained knitting loop to the head of the needle. The needle is actuated to pick up the yarns and the needle adjacent to them is actuated to pick up the yarn or yarns in the “jaw” position. Upon subsequent rotation of the needle cylinder, knitting for the previous rotation is resumed. In particular, in this third feed, the needle that picked up the bare elastomeric yarn in the first feed is re-actuated in the “jaw” position for another predetermined number of revolutions of the needle cylinder.

In the third feed, the needle is lowered to form a new knitting loop after picking up the yarn or yarns.

In the fourth feed, the needles of each needle group are selected and actuated in a manner similar to that practiced in the second feed.

In the fourth feed, the needle is lowered to form a new knitting loop after picking up the yarn or yarns.

In multiple revolutions of the needle cylinder about its own axis to form the knitting, during the formation of the gripping area, after a predetermined number of revolutions of the needle that picks up the bare elastomeric yarn from the first feed as described above, the second At 3 feeds, it should be noted that, apart from the various actuations, the selection of the needle at various feeds does not change.

In the third feed, the preset number of revolutions of the needle cylinder before the actuation in the "drop" position of the needle picking up the bare elastomeric yarn in the first feed is performed is substantially 4 to 9.

It should also be noted that, in the second and fourth feeds, the needles that picked up the bare elastomeric yarn in the first feed are actuated in a “jaw” position to pick up the yarn or yarns dispensed by these feeds.

The tubular knitted article obtained by the method according to the invention, generally denoted by reference number 1, has on its backside a gripping area, said gripping area projecting on the backside of the article and knitting together with the other yarns constituting the article. formed by a bridle or floating portion of a bare elastomeric yarn. The floating portion or bridle of yarn 3 is produced by not picking up the bare elastomeric yarn by needles of various groups of needles either moved to a “miss” position in the first feed or constrained to a second position, as described above. do.

The gripping region 2 is preferably formed by one or more circumferential bands 4 , each circumferential band comprising those of the bare elastomeric yarn 3 parallel to each other along the axis 1a of the article 1 . It consists of a number of turns or rows of floating parts.

In the embodiment shown in the drawings relating to the hold-up stocking, the gripping area 2 consists of three circumferential bands 4 , which circumferential bands mutually along the axis 1a of the product 1 . are spaced apart

1 shows a semi-finished product for producing a hold-up stocking as it is taken out from a circular hosiery knitting machine which produced the hold-up stocking or rather the semi-finished product. These semi-finished products are open at both ends. One of these two ends will be closed by sutures or looping to provide the finished product.

The gripping area 2 obtained with the method according to the invention is positioned adjacent to the opposite end, ie the end constituting the upper end of the hold-up stocking.

The bare elastomeric yarn forming this gripping region 2 is preferably made of silicone rubber.

Conveniently, in the gripping area 2 , the product 1 is preferably pretensioned of the bare elastomeric yarn 3 while being fed to the needles of the knitting machine in the production of this product 1 . and a corrugated portion 5 created by

As can be inferred from the above description of the production method, the knitting-in of the bare elastomeric yarn 3 with the yarns constituting the rest of the product 1 is carried out by tuck-stitch knitting and ,

The knitted-in stitches, ie the stitches for connecting the floating part of the bare elastomeric yarn 3 to the rest of the product 1 , are preferably aligned parallel to each other on the axis 1a of the product 1 .

Preferably, each floating portion of the bare elastomeric yarn 3 extends for a plurality of rows of stitches of substantially 6 to 15 stitches.

The yarn used to make the article, different from the bare elastomeric yarn, may be composed, at least in part, of an elastically stretchable yarn.

The method according to the invention makes it possible to unload from a circular hosiery knitting machine the product 1 already provided on the back side with a gripping area 2 which can be used to hold the product 1 on the skin of a user. make it In particular, when this product consists of a hold-up stocking, this gripping area ensures optimal effectiveness in holding the upper end of the stocking on the user's thigh, and effectively suppresses descent and curling during use.

In particular, during the production of the gripping region 2 , the needle picking up the bare elastomeric yarn 3 in the first feed of the knitting machine is moved to knit in the “jaw” position in the subsequent feed, so that another row of knitting (bare elastomeric yarn) The effect of having the heat of knitting (those formed by the needles picking up the bare elastomeric yarn 3) with a lower elastic yield compared to that produced by the needle that did not pick up (3) is achieved. This particular method of implementation of the gripping area 2 achieves the effect of doing the inside of the product, i.e. elastically adding this area towards the user's skin, effectively suppressing the product's outward curling.

The optional and preferred implementation of the elastically stretchable corrugated portion 5 has the effect of further reinforcing the resistance of the product to curling.

By way of non-limiting example only, two examples of practical implementation of the method according to the invention for producing hold-up stockings are given below.

Example 1

A single-cylinder circular hosiery knitting machine with 400 needles and 4 feeds or drops is used.

The needles of the knitting machine are divided into groups of 12 needles.

The product 1 to be provided is a hold-up stocking of the type shown in the drawings.

The production of the product 1 is started from the upper end of the product 1 , ie the end opposite to the toe of the stocking.

After a predetermined number of turns of the needle cylinder in which the initial part of the stocking is provided in a known manner, the provision of the gripping area 2 is initiated and carried out as follows.

After the first feed, the knockover cam is extracted in the sense of being inactive so as not to actuate the needle.

In the first feed, the bare elastomeric yarn 3 is dispensed, and the needles of each needle group are selected according to a selection of 1:11, so that one needle in this group is the bare elastomeric yarn (3) in the “tuck” position. 3) is actuated to pick up, the other eleven needles are moved to the “miss” position or constrained to the “miss” position. Upon deactivation of the knockover cam, the needles of each group that picked up the bare elastomeric yarn 3 already move to the second feed in the "chin" position, or more precisely in a position slightly elevated above the "jaw" position. .

In the second feed, each group of needles is selected according to a 1:1 selection so that for every two adjacent needles one needle is actuated to pick up the yarns dispensed by the feed in a “jaw” position, while the other needle is It is operated to pick up the yarns dispensed by the feed in a “drop” position. The needle that picked up the bare elastomeric yarn 3 in the first feed is one of the needles that picks up the yarns at the “tuck” position in this second feed. In this second feed, the needle is fed with 3 yarns, two of which are 78/46 (78 decitex and 46 strands) and one 44/34 (44 decitex and 34 strands). The supply of three yarns in the second feed has the function of strengthening the gripping area 2, effectively preventing this area from curling in use.

After picking up the yarns dispensed by this second feed, the needle is lowered to form a new knitting loop.

In the third feed, for each group of needles, a 1:11 selection of needles being raised to pick up yarns in the “tuck” position and 11 needles being raised in the “drop” position is performed. The needle raised to the “chin” position is the needle that picked up the bare elastomeric yarn 3 in the first feed. This takes place during a preset number of revolutions of the needle cylinder, preferably equal to 4, then during only one revolution in the fifth revolution this needle is raised to the "drop" position and the adjacent needle to the "jaw" position rises In this feed, two 78/46 yarns (78 decitex and 46 strands) are fed to the needles of both the raised needle to the "jaw" position and the lowered needle to the "drop" position.

After pickup of the yarn dispensed by this third feed, the needle is lowered to form a new knitting loop.

In the fourth feed, each group of needles is selected according to a 1:1 selection, as in the second feed, so that one needle for every two adjacent needles picks up the yarns dispensed by this feed in the “jaw” position. while the other needle is operated to pick up the yarns dispensed by this feed in a “drop” position. The needle that picked up the bare elastomeric yarn 3 in the first feed was one of the needles that picked up the yarns at the “tuck” position in the fourth feed. In this fourth feed, the needle is fed with 3 yarns, of which 2 are 78/46 (78 decitex and 46 strands) and one is 44/34 (44 decitex and 34 strands). Also in this case, the supply of three yarns has the function of strengthening the gripping area 2 , effectively preventing this area from curling in use.

After pickup of the yarn dispensed by this fourth feed, the needle is lowered to form a new knitting loop.

By this technique the three circumferential bands 4 are provided with a portion of the bare elastomeric yarn 3 floating on the back side of the article 1 . The circumferential region located between the circumferential bands 4 with the bare elastomeric yarn 3 can be provided in a manner known per se or as described, but on the needle the bare elastomeric yarn 3 ) may be omitted to provide

Optionally, before starting the provision of the gripping area 2 , several revolutions (three revolutions in the illustrated embodiment) of the needle cylinder can be performed, in the course of which at the first feed during the provision of the gripping area 2 . Some of the needles, which are preferably different from the actuated one, are fed with bare elastomeric yarn 3 (optionally always dispensed from the first feed), while other needles are excluded from the pickup of the bare elastomeric yarn 3, so the height is A reduced circumferential band (4) is obtained and also floats on the back side of the product (1) selectively offset with respect to the floating portion of the bare elastomeric yarn (3) in the gripping region (2). (3) has a part.

After the provision of the gripping area 2 , the production of the product 1 continues in a manner known per se up to providing the toes of the product 1 , after which the product 1 is taken off from the knitting machine.

Example 2

A single-cylinder circular hosiery knitting machine with 400 needles and 4 feeds or drops is used.

As in Example 1, the needles of the knitting machine are divided into groups of 12 needles.

In this second example of a practical embodiment of the method according to the invention, the same operations as already described in example 1 are carried out, with the difference being that the bare elastomeric yarn 3 is picked up from the first feed of the knitting machine. The needles of each group of needles operated for this purpose are moved to knit in the “drop” position instead of the “chin” position.

Indeed the method according to the invention does not require the execution and/or knitting of a double welt to provide such a gripping area, the product having a gripping area on the back side provided directly during the formation of the product using a hosiery knitting machine, It has been found, in particular, to fully achieve the intended purpose, as it makes it possible to manufacture hold-up stockings.

Another advantage of the method according to the invention is that it makes it possible to provide a product in which curling of the gripping area does not occur during use.

The method envisioned in this way is susceptible to many modifications and variations, all of which are within the scope of the inventive concept, and all details may be replaced by other technically equivalent elements. Thus, for example, manufacture of an article may be initiated from one axial end thereof or from the other axial end, ie from the toe or from the top in hosiery.

Although the present invention has been specifically described for the manufacture of hold-up stockings, the present invention may also be used to manufacture other types of hosiery, such as, for example, knee-high, or other types of tubular finished or semi-finished products. can

Indeed, unless otherwise stated above, the materials and dimensions used may be arbitrarily selected according to the requirements and the prior art.
