Seamless knitted garments and their method of manufacture

The invention relates generally to seamless knitted, Garments with two leg parts for the lower part of the human body, e.g. panties, Panties, suspender belts, parts of bathing suits, leotard leg dresses, tights and the like on methods for their Manufacture, and particularly relates to such garments having a waist opening that has a so-called "self-edge" or Salkante, i.e. a knitted edge or a knitted end strip or braid which has been produced during the knitting process, so that it is not necessary after knitting is to slit the garment to provide a waist opening.

It is known to produce garments of the type mentioned with two leg sections on a circular knitting machine- ' len; Here, a leg section is first knitted from consecutive complete courses, then a Panty part formed by forming a first shaped extension from partial rows of stitches, whereupon knitted, connected, shaped front and rear twists are produced from partial rows of stitches, after which a second

shaped extension knitted from partial stitches becomes, and finally a second leg section is made, one on top of the other following complete courses of stitches. In order to form the waist opening, one is made in the direction of the wales running slit is created so that the front and rear gussets are separated from each other, and to the To complement the waist part, an elastic belt strap is attached to the edges of the slit. With two leg sections fitted garments of this type, as well as the methods of knitting the same, are disclosed in, for example, U.S. Patents 2,962,884, 3,109,300 and 3,109,301. It is true that, according to these U.3.A. patents, the design of the Body portions vary, but the anterior and posterior gussets are interconnected at their upper ends and they must be separated by hand by making a slit to form the waist opening. After this is done, an elastic band is tied around the edges of the waist opening around the garment to make ready for use. This way of working naturally leads to an increase in the cost of manufacturing such garments, and the exact arrangement of the slot depends on the skill of the worker producing it.

It is also known, pantyhose and the like. In the To make it, knit an elongated seamless tube, knitting the middle part of the tube in Slit in the direction of the wales to form a waist opening and that you finally get to the garment attaches an elastic band. The opposite ends of the elongated tube are closed and form the leg and foot sections of the garment.

In view of the above, the object of the invention is to provide a one-piece, seamless, To create two legged garments for the lower part of the human body., be: i dem during the knitting process one delimited by self-edging Waist opening is formed, so that a subsequent

309821/0667

No need to slit by hand. Further through the invention a seamless two leg garment of the type mentioned has been created in which it it is possible to work elastic yarns into certain sections of the panty part. For example, you can use an elastic Work yarn into all parts of the front and / or back gusset. It is also possible to use the elastic Yarn in a few wales at the top of the dividing rows of the front and back gussets like this incorporate that in the part of the garment surrounding the waist opening a knitted fabric elastic band is formed. Finally, the invention provides a method of knitting seamless two leg sections having garments of the type mentioned have been created, which durchxiinren on a circular knitting machine lets, and. to use the circular knitting machine only needs to be modified to a small extent.

A seamless knitted garment according to the invention includes an ilove section and two associated with it ^ eatricked leg sections, each of which is made up atif successive complete courses of stitches formed is. The panty section has shaped extensions formed from partial courses and extending from each Leg section from extending upwards, as well as shaped front and back gussets, which consist of partial courses and are knitted in such a way that they come with the shaped extensions related and connected to each other. The front and the back gusset consist of partial rows of stitches, which extend perpendicularly in relation to the panty portion. The lower ends of the partial courses the front and back gussets are connected to the partial courses of the extensions, while the top ends of the partial rows of stitches of both gussets form soap edges, which keep the two gussets separated from one another and at the same time define a waist opening at the top of the panty section. The leg sections can be short so that you can

309821/0667

a pair of panties or the like. Or you can extend them and close at their lower ends so that they the Form leg and foot sections of tights, a jersey or the like.

The articles of clothing according to the invention are preferably produced on a circular knitting machine for hosiery products, which is designed so that the needle cylinder can temporarily be rotated continuously, and that it during other periods of time is rotated back and forth in order to produce shaped partial stitches.

The invention and advantageous details of the invention are shown below with reference to schematic drawings Embodiments explained in more detail. It shows:

According to Pig. 1 to 3 is the raw part for the shown Garment with the desired lorm knitted so that one obtains pantyhose with two seamless tubulars Leg sections 10 and 11 belong, each of which is composed of successive complete courses. As indicated by hatching lines in Mg. 1 to 3, the courses of stitches in the leg sections run essentially horizontally or transversely to the longitudinal axis of the leg sections. Referring to Fig. 2, the upper ends of the leg portions 10 and 10 extend 11 to dash-dotted lines 12 and 13, and the inner parts of the leg portions are in the crotch along the dashed lines Line G interconnected in a manner to be described.

The panty section of the garment has shaped Extensions 14th and 15th that extend from the leg

309821/0667

~ ⁶ ~ 224B462

sections 10 and 11 extend from up and through Formed partial rows of stitches are formed. There are also shaped front and rear gussets 16 and 17, which are knitted to the shaped extensions 14 and 15 and connect them to one another. The two gussets 16 and 17 are made up of partial rows of stitches that run in a vertical direction, and their lower end with them opposite ends of the partial courses of the extensions 14 and 15 are connected, while their upper ends knitted soap selvedges define a waist opening at the top of the panty section.

v As in the three U.3.A. patents mentioned at the beginning described, the knitting of the shaped extensions 14, 15 and shaped gussets 16, 17 can be followed Vary as needed so that these sections are given a greater length or width or some other shape. The design of the part of the garment enclosing the torso is used in the following in connection with the description of the garment Knitting process described. The shaped parts of the panty section are made along seam or gusset lines united with each other. For example, the opposite ends of the partial courses are in the lower Sections of the shaped extensions 14 and 15 along vertical front and rear gusset lines 20 and 21 connected to each other. The lower ends of the partial courses of the front gusset 16 and the rear gusset 17 with the opposite ends of the partial rows of stitches of the extensions 14 and 15 are inclined longitudinally extending front center lines 22, 23 and rear intermediate lines 24 and 25 connected to one another.

When knitting the pantyhose according to FIG. 1, the knitting process is started at the lower toe end of the leg section 10, and the needle cylinder of the circular printing machine rotates continuously, usually in the opposite direction clockwise.

309821/0667

Here is the desired main yarn, "in which it is is usually a so-called stretch yarn, fed to all needles of the needle cylinder, so that with each revolution of the Needle cylinder a complete row of stitches is created. It is possible to process a reinforcing yarn together with the main yarn during the creation of the toe or heel section, and the leg portion 10 is usually knitted from a finer yarn to make the leg portion transparent do. As indicated in Fig. 1, 5 and 6 by the line 26, it is usually convenient to make the panty section using an additional reinforcement thread or but to be knitted from a stronger yarn.

Once all the stitches are complete in the leg section 10 have been knitted up to the dot-dash line 12 in Fig. 2, the group of needles that are used for this serve to form the crotch portion along the dashed line 0 in Fig. 2, brought into a rest position in which they remain ineffective. These needles are usually raised so that they are above the knitting cams move and hold the stitches on them while the remaining needles are in their lower position, i.e. the Working position, whereupon the needle cylinder begins to rotate back and forth. Then in Activity needles knitted partial courses to form the shaped extension 14, while the usual Removal devices of the knitting machine are used to measure the length of the partial rows of stitches up to the dot-dashed Line 28 in Fig. 2 to gradually decrease. The ones that were brought into their upper resting position during this weight loss process Needles hold the stitches on them firmly.

The circular knitting machine can be constructed as described in U.S. Patent 3,292,392 and at of the group of partial courses between the chain lines 12 and 28 in Fig. 2, the number of stitches becomes preferable relatively slowly gradually decreased, e.g. by one stitch at each end every second row of stitches,

3 09 821/0667

The needles brought up into their rest position hold the associated stitches tight until they are back in their working position be brought while the shaped extension 15 is knitted so that the perpendicular yerlaufenden front and rear gusset lines 20 and 21 arise. Above the dot-dash line 28, the needle cylinder further twisted back and forth, and the length of the partial courses is gradually reduced more quickly, with certain Rows of stitches at the ends of the rows of stitches existing needles are brought into the rest position. For example, one needle at a time can be lifted to remove the to hold the associated mesh while each one of the one on top of the other following row of partial stitches. The needles brought into the rest position hold those stitches which form the front gusset line 22 and the rear gusset line 24 at a later point in time.

Near the top of the shaped extension 14, i.e. along the dashed line 30 in Figure 3> the speed of decreasing is reduced while a few last partial courses of very short length are knitted will. The last partial course of the extension 14 is knitted on a very small number of needles, like it in Pig. 3 is indicated by the bracket 31. Then this group of needles, by means of which the last partial stitch row the extension 14 was knitted, brought down to a rest position so that these needles are below move the stitch formation cam and hold the stitches on them. As indicated in Fig. 7 to 9 at 31, this group of ineffective needles remains in its lower position, while the front gusset 16 and the back gusset 17 can be knitted on opposite sides.

During the further reciprocating rotary movement of the needle cylinder, the two shaped gussets 16 and 17 are then knitted on groups of needles arranged on both sides of the group of needles 31 which are in their rest position

309821/0667

are. While knitting over the first partial course both the front gusset 16 and the rear gusset 17 are needle groups 32 and 33 from their rest position moved downwards at the same time and brought into their working position on both sides of the ineffective needles 31.

These simultaneously activated needle groups 32 and 33 produce what is known as the waistband section and denote the knitted soap selvedges which define the waist opening at the top of the panty section delimit. When knitting the first partial row of stitches of the front gusset 16, in which the needle cylinder turns clockwise according to Mg. 7, this becomes the Partial courses of the front gusset processed yarn Y-1 is fed to the working needles of group 32, to form the first row of partial stitches on all working needles and the resulting stitches with the last To join stitches held in place by the needles attached to the top while knitting the partial courses At the end of extension 14 were brought into the boo position. The yarn Y-1 is fed through a yarn feeder 40, the on a plate 41 of the Knitting machine is mounted so that it can-be moved between a working position and a rest position. While the group 32 of working needles moves past the plate 41 to take up and process the yarn Y-I, the feed finger 40 is brought up to its rest position, and a second feed finger 42 is brought down moved and brought into its working position, in which it feeds a second yarn Y-2 to the working needles of group 33 can to produce the first partial course of the rear gusset 17. While the needle cylinder according to FIG continues to rotate clockwise, the working needles of group 33 grasp the yarn Y-2 in order to process it and the first partial stitch row of the back gusset 17 z.U. form, where the stitches at the ends of the partial courses at the upper end of the extension 14 are connected to this partial course.

309821/0667

As soon as the needle cylinder rotates counterclockwise as shown in FIG. 8, the yarn Y-2 is again through the lowered feed fingers 42 the working needles of the Group 33 fed to produce the second partial stitch course of the rear gusset 17. Then the feed finger 42 is moved up, and the feed finger 40 is lowered, while the inoperative needles of the group 31 move past the plate 21, so that the working needles of Group 32 pick up yarn Y-1 and process it to the to form the second row of stitches of the front gusset 16. Thus, the yarn Ϊ-1 extends from the last one formed Stitch of the first partial stitch row of the front gusset 16 to the first stitch formed of the second partial stitch row of the front gusset to form a knitted self-edge along the upper hand of the front gusset. During the next clockwise movement of the needle cylinder is according to Pig. 9 the yarn Y-1 through the in its lower position brought fingers 40 fed to the working threads of group 32, around the third row of stitches in the front gusset

16 to generate. During the same clockwise movement the yarn Y-2 is fed through the yarn feed finger 42, which is then in its lower working position, around the third row of stitches in the back gusset

17 on the working needles of group 33 as these needles move past plate 41. Consequently the yarn Y-2 extends from the last formed loop of the second partial course of the rear gusset 17 to the first formed stitch of the third partial stitch row, so that at the upper end of the rear gusset 17 a knitted edge is formed. As the needle cylinder continues to be turned back and forth, the length of the pitch courses becomes within of the front gusset 16 and the rear gusset 17 »produced by the working needles of groups 32 and 33 are gradually enlarged. The stitches at the lower ends of the partial courses of the 'two gussets are each with the last stitches of the partial rows of stitches of the extension 14 along the front gusset line 22 or the rear Gusset line 24 connected.

309821/0667

Once in the middle of the gusset 16 and 17 the maximum Number of needles to be used is reached, the number of needles is gradually reduced, and for this purpose the needles in question at the lower ends of the two gusset forming partial courses up into their Brought to rest position. The number of needles that make up the successive pitch courses within the second halves of the two gussets are gradually reduced until the number provided for groups 52 'and 33 is reached again is reached. Then all these working needles are made ineffective, i.e. moved up to their rest position, in which they hold the stitches on them. At the same time, the needles, which had been ineffective until then, become of group 31 is put into operation and the yarn Y-1 is fed inside to the first pitch course of the extension 15 to generate. Since the needles 31 held the stitches present on them of the last partial stitch row of the extension 14 have, these partial rows of stitches are now connected to one another.

While the needle cylinder continued to rotate back and forth becomes, the number of needles, which produce a few first pitch courses of the extension 15, gradually enlarged until the dashed line 45 is reached according to FIG. 3. With the further back and forth turning movement of the needle cylinder, the ends of the partial courses of the extension 15 with the last stitches of the partial courses connected to the lower ends of the front gusset 16 and the rear gusset 17 so that the front gusset line 23 and the rear gusset line 25 arise. At the same rate of enlargement or widening of the partial rows of stitches work is carried out in the upper section of the extension 15 until the dot-dash line 48 according to FIG. 2 is reached, and then the speed of increase is reduced so that the stitches at the ends of the partial courses the extension 15 between the dash-dotted lines 48 and 13 with the stitches at the ends of the rows of partial stitches

3098 21/0667

224846?

Extension 14 can be connected to the front and rear vertical gusset or connecting lines 20 and 21 produce. As soon as these partial rows of stitches are completed down to the dash-dotted line 13 in Fig. 2, the needle cylinder starts rotating again and complete courses are knitted on all needles, to knit the upper part of the leg portion 11; the needles that make the stitches are also used here in the crotch area along the dashed line C in FIG. 2 held on. Now the required number of complete courses is produced until the leg section 11 the has the desired length; According to FIGS. 1, 5 and 6, a yarn change can again be made on line 50 so that a transparent leg section is created.

The manner in which the top knitted soap edge of the front gusset 16 is formed is best illustrated in Fig. where it is shown that the course courses C-10 to C-12 are knitted in the directions indicated by arrows will; here the yarn Y-1 forms the first stitch in the wale W-1 of the partial stitch course C-10 and then the last stitch in w-1 of partial stitch row 0-11, in order to then take such a course that it is the first Forms a 0-12 row of stitches. It should be noted that the partial courses of the rear gusset 17 also includes a knitted soap selvedge similar to that shown in FIG.

It is also possible to use a garment-related elastic band in a few wales of the upper sections of the partial courses of the front Knit gusset 16 and the back gusset 17. For this purpose, according to FIGS. 7 to 9, two can be seen in the plate 41 additional yarn feed fingers, which serve to feed an elastic yarn, which is shown in FIG. 10 at E-1, a predetermined number of needles to produce the uppermost ends of the partial courses of the two gussets. According to Fig. 10, the elastic yarn E-1 is processed so that

309821/0667

- ™ r 2248482

that a plating of the main yarn Y-1 within a few fewer wales are obtained that extend downward from the upper edge of the soap. The movement of the appropriate The pinger for feeding the elastic yarn is the same as that of the fingers for feeding the main yarn, apart from the fact that they only feed yarn to a few needles, which are the top wales of the partial courses of the two gussets. The elastic yarns form a front and a back, connected to the garment elastic bandj these elastic bands are designated in Mg, 1 to 6 with B-1 and »B-2, respectively.

According to Mg. 3, the adjacent ends of the elastic bands B-1 and B-2 are not connected to each other, but in each case separated by a few rows of partial stitches in the upper sections of the extensions 14 and 15. True is it is possible to wear the garment without the ends of the two elastic bands being connected to each other, however, it is preferable to have the elastic bands on both To connect sides of the garment in the manner shown in Fig. 4 by short seams 52 and 53 together. To attach the stems 52 and 53, the adjacent ends of the elastic bands B-1 and B-2 can be pulled together, the Fold excess material in between and then create overcast seams along the fold lines.

If the panty part of the garment is in the foregoing has been knitted in the manner described, the last partial course of the extension 14 is with the first Partial stitch row of the extension 15 connected, and this Both rows of stitches must be separated from each other, e.g. by cutting the yarn before the ends of the elastic Bands B-1 and B-2 are joined together by seams 52 and 53. However, it is also possible to use the panty part to knit without the partial courses of the extensions 14 and 15 are connected to each other. For example, can you raise and lower the needles, which create the last partial stitch row of the extensions, by the last one

309821/0667

Partial rows to knock off, and these needles can be used during knitting of the front and back gusset will not work. Then you can use every second one of these needles so that they take up yarn to establish a starting point from which all needles are knitted which is the first partial course of the extension 15 generate. It is also possible to have a few rows of partial stitches of the same length to make a 1 mm strip create the upper ends of the extensions 14 and 15 connects with each other.

Although it has been described with reference to Fig. 10 that the elastic yarn E-1 in conjunction with the main yarn Ϊ-1 as Plating yarn inside a few maize sticks is used to create the elastic band B-1, however you could put the elastic yarn together with the main yarn also work into the garment up to the lower ends of the partial courses of the front gusset 16 so that the garment is provided with an elastic gusset on its front. Furthermore, one could use the elastic Yarn also within the rear gusset 17 and / or within the shaped extensions 14 and 15 together work with the main yarn.

If the intention is to produce a pair of panties, panties or the like, the leg sections 10 and Make 11 very short and hem them at their lower ends. You can also use any type of yarn you want process and any desired mesh structure for both the leg sections and the panty part of the garment provide.
