The manufacture region is produced by providing in succession portions of rows of knitting obtained by actuating the needle cylinder with a two direction rotary motion.

Description

1329688 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a circular knitting machine having a needle cylinder that can be rotated in a double rotation direction, and a specific t-shou tiantian A + No. A method of weaving a manufactured article by using a circular knitting machine of a fineness and a height gauge. This is enough for the knitwear or the like to pass the braided ring from the needle forming the needle to the knitting machine 邻近p adjacent to the needle to fly your wife (for example) at WO- Such a machine is disclosed in 02/070799.

[Prior Art] Up to now, this technique for transferring a braid has been mainly used to obtain a porous fabric in an article. An example of the application of this technique to porous fabrics is given by the same applicant in WO 2005/080653. A method of weaving a shaped article using a circular or braiding machine is also known to increase the number of active needles in a defined area of the article. This technique suffers from the drawback of allowing only the addition of the movable needle, and therefore it is desirable to start the woven article from the side of the region where it has to be woven with a minimum number of needles. This fact limits the possible weaving procedures and the shapes that can be obtained using this technique. Circular knitting machines are also known to have a syringe that can be activated by a rotational movement about its own axis in a double rotational direction. By utilizing the possibility of activating the syringe in both directions of rotation, such machines allow for the production of articles in areas such as sweatshirts, bodysuits or the like, or underpants, tights or the like. The crotch region of the article where the edges have been trimmed without subsequent trimming and/or trimming operations. Even with these machines, it is not always possible to produce products that do not require cutting and/or trimming interventions, since they only increase the number of active needles during weaving Π 2125.doc 1329688. For example, if it is necessary to provide a woven region including a plurality of stitches which are gradually increased in manufacturing, and then a woven region including a plurality of stitches which are gradually reduced, it is conventionally possible to perform cutting by producing an article on a machine. Get the shape you want to get these last areas. SUMMARY OF THE INVENTION It is an object of the present invention to provide a utilization that can be surrounded in a double rotation direction

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, in the embodiments of the present invention for producing articles of manufacture such as tights, it will be appreciated that the method according to the present invention can also be used to produce other types of articles. product. The article of Fig. 1 is provided by starting the weaving from the underside (i.e., the area of the crotch from the bodysuit). Initially, the two sets of adjacent needles belonging to the two sector gears located at the cylinders (they are angularly spaced from each other about the axis of the barrel) are knitted to provide front and rear regions that form the lower portion of the bodysuit. Areas E, F of the product. The number of needles applied to the weaving of the two sets of needles is gradually increased to obtain a shape in which the widths of the front region E and the rear region F are gradually increased. The increase in the number of needles applied to the weaving of the two sets of needles is performed in a manner known per se, for example, by using a needle selection device typically provided by modern circular knitting machines. Preferably, the regions E, F are produced by the following steps: starting the syringe with an alternate rotational movement about the axis of the syringe; successively producing portions of the braided rows of the region E and the region f (which are utilized by one The rotational movement of the direction of rotation about the axis of the barrel initiates the barrel and is provided by weaving the needles of the two sets of needles at one or more separate feeders or needles of the machine) and alternately producing The syringe is activated by a rotation H2J25.doc ^29688 motion around the axis of the syringe in the opposite direction and by knitting the needles of the two sets of needles at the same feeder or needle of the machine. The score of the weaving column of the area E and the area f is provided. Reversing the rotation of the syringe after the last needle (which has been moved to the weaving of the two sets of needles) passes through the yarn feeder or needle drop used (the line used to form part E and/or f is dispensed here) Direction In this way, after the article is unloaded from the machine, the ends of the Ε, f do not require cutting and/or trimming operations.

The detail of the weave close to one end of the portion ρ· is shown in FIG. Behind the heart's production of the tubular portion G of the article 1, which can be activated in a manner known per se by utilizing a continuous rotational movement about the axis of the syringe and by fully making all the needles of the syringe in the machine Or multiple yarn feeders or needles are woven to obtain. In this step, certain needles of the syringe can be withdrawn from the braid to achieve a particular patterning effect or shape in this region of the article. Furthermore, during the production of the part G, it is possible to provide the cup areas H, I of the bodysuit in a manner known per se. After Part G, the areas A, B, C, D of the accessories that make up the shoulder straps of the tights are produced. In accordance with the present invention, each of these regions A'B, C, D is produced using a set of adjacent needles by gradually reducing the number of active needles in the set of needles. Passing or transferring the braided loop by transferring the last braid formed by the particular one of the set of needles to adjacent ones of the same set of needles and thus forming a portion of the subsequent braided column by the needles that are held in motion Weaving to achieve a reduction in the activity of the needle. The areas A, B, C, and D of the product are produced by the following steps: H2125.doc 1329688 is provided in succession. The use of a needle in a thread is used to "spin the needle itself." The rotational motion of the shaft initiates a portion of the braided column in the opposite direction, and (4) provides a portion of the braided column produced by initiating the cylinder by rotational motion of the needle shaft by utilizing the production of the sensitivity. It is an enlarged view of the area (the thin side of the side) of the side of the region C (the left side in FIG. 1), and FIG. 3 is an enlarged view of the detail of the area C near the opposite side (the right side of the figure )).

In Figures 2 and 3, for simplicity I, the performance of region c has been limited to eight-needle weaving' in Figure 2 by reference numerals! Up to 6 and its woven column is indicated by reference numerals ^ to 16 in FIG. In Figures 2 and 30, the formation of the woven region c is performed from the bottom upwards. See Fig. 2', for example, as provided by w〇_〇2/〇7〇799, which is known per se. 6) '#After the formation of the subsequent portion of the braided column 22, the final braided loop 2H of the portion of the braided row 2 formed by the needle N forming the column 1 is transferred to the needle N forming the column 2 to obtain the activity. The reduction of the needle. In this manner, during formation of the portion of the braided column 22, the needles N forming the column 1 are caused to exit the weave while the needle N forming the row 2 is woven, and the other needles N of the needle set are also so The braided loop 222 is knitted into the new braid by the two braids 211 and 212 (wounded) carried by the needle. Prior to beginning the weaving of the lower portion of the column 23, the needle n of the column 2 is discarded or self-formed to the adjacent pin N of the column 3 to transfer the braid 222. During the formation of this portion of the braided column 23, the needles forming the column 2 are also withdrawn from the weaving' while the adjacent needles forming the column 3 are woven, and the other needles in the set of needles are so "to form a new braided loop 233" The new braided loop is programmed with two 112125.doc 1329688 braids 222 and 223 (wounded) that are carried by the needle. It should be noted that the syringe Cy is activated by the rotational movement of the twisting direction about the axis of the barrel to produce the portions of the braided rows 21 and 23; and by utilizing - in the opposite direction around the axis of the syringe The rotary motion activates the syringe Cy to produce the portion of the braided row 22. Referring to Fig. 3, the method known per se (for example) in WO 02/070799 (see Figs. 5 and 6) is used to form the underlying woven column 32.

Previously, the last braid 3116 of the braided row 31 formed by the needles forming the column 16 is transferred to the needle forming the column 15 to obtain a reduction in the movable needle 2. In this manner, during formation of the portion of the braided column 32, the needles forming the column 16 are withdrawn from weaving while the needles forming the column 15 are woven, and the other needles in the set of needles are thus so as to form a new weave. The circle 32 is 5, and the new braid is knitted by the two braids 3116 and 3115 (wounded) carried by the needle.

Prior to beginning the weaving of the lower portion of the column 33, the braided weir 3215 is transferred from the needle forming the column 15 to the adjacent needle forming the column 14. During the formation of the portion of the braided column 33, the needles forming the column 15 are also withdrawn from the weave while the adjacent needles forming the column 14 are woven, and the other needles in the set of needles are also so as to form a new braided loop 33.丨4, the new braid is knitted by the two braids 3215 and 3214 (wounded) carried by the needle. It should be noted that the portions of the braided rows 31 and 33 are produced by activating the syringe with a rotational motion about the axis of the syringe in a rotational direction while utilizing a self-axis that surrounds the syringe in the opposite direction. The rotary motion starts H2l25.doc 1329688 to move the syringe to produce the portion of the braided column 32. The weaving of the region C is carried out in such a way that the syringe is activated by the use of a parent-moving motion around the axis of the syringe, the shape of the portion being broad and wide (and up to and including the provision of the crucible) production area C The number of active needles in the set of needles. A, B, and D are in a manner similar to that described in reference area C. This - ' = braided needles remain retracted within the barrel, under the sinker, 'U' to interfere with the operation of other needles or other components of the machine. By which way, in this way, it is possible to obtain a gradually decreasing width for the regions A, Β, C, D, which has an edge that does not require a step-and-step trimming operation. For the sake of simplicity of the whispering, in the examples described above with reference to Figures 2 and 3, it has been assumed that the number of active needles in the set of needles providing region C is reduced before each portion of the woven column begins. In practice, depending on the shape to be obtained for the regions, the number of active needles in the production zone A, B, C, D can be reduced for each or more successive portions of the weave column. Furthermore, if a smaller-width reduction is obtained which alternates with the width-of-width of the zones, the month b is reduced in a manner known per se, in one step of the weaving process and in the other step of the weaving process. The number of needles applied to the set of needles. In the production, when the Q bundle is used, the articles are released by the needles and unloaded from the machine. As an alternative, the joining of the two regions constituting the same shoulder strap or crotch can be performed on the same circular knitting machine (for example, by observing the same as disclosed in the Italian Patent Application No. MI2004A_002495 by the same application. Method) to trim the article directly on a circular knitting machine for producing the article. Although the method according to the invention has been described with reference to the production of the forming region of the bodysuit, the method can be used to obtain a shaped area on other articles such as underpants, undershirts, tops or the like. y

It should be noted that with the method according to the invention it is also possible to produce the article b by starting the weaving from the upper end, in this case, by gradually increasing the number of needles producing the parts in a manner known per se. The needles, and or by the fact that the needles G of the two sets of needles of the production zones E, F are gradually reduced according to the invention, by transferring the last braided loop formed by the subsequent withdrawal of the needles to the adjacent needles) Areas a, b, c, d. In practice, it has been found that the method according to the invention fully achieves the intended purpose 'because A uses a weaving ring to transfer the needle from the needle to the adjacent needle to reduce the movable needle coupling system—in the double rotation direction, the (four) rotation of the cylinder itself The technique of activating the syringe can allow for the provision of an article (even an article having a high degree of fineness) having a shaped area that is not necessarily a cutting or trimming operation, regardless of the side from which the weaving of the article begins. The method of sighing allows for dry corrections and changes, all of which are included in the scope of the patent scope attached; additional technically equivalent elements can be used to further replace all such details. The materials used in the practice and the dimensions may be any materials and sizes that meet the requirements and the state of the art.
