Description

PROCESS FOR KNITTING KNITTED CYLINDRICAL FABRICS

  The present invention relates to a knitting method which is used for integrally knitting different knitted pieces in a cylindrical configuration such as clothing using a flat knitting machine, in particular a knitting method for cylindrical knitted fabrics which

  decrease a diameter of the cylindrical knitted fabric.

  It was already known before the filing of the present application methods in which during the production of clothing or the like, using fabrics knitted by a flat knitting machine, a strip of knitted fabric is knitted flat, and predetermined parts of an end edge of this strip are sewn together to thereby form a body part or other parts giving them a cylindrical shape (Japanese Patent Publication Nos. 23022/1982 and 53455/1982). However, in garments or the like obtained in this way, the ends of the knitted fabrics are sewn together, and therefore the sewn part has poor elasticity, and furthermore, the sewn part protrudes inside the garment, which does not not allow to obtain a satisfactory impression of comfort during the wearing of the garment, from which it results in poor possibilities of shaping, and sometimes a fraying of certain parts. In addition, sewing work is necessary, it increases the number of operations and harms

the productivity.

  Given the observations mentioned above, an object of the present invention is to provide a knitting method for reducing knitted stitches in parts of continuous and integrated knitting which correspond to the parts sewn in the knitting operation of knitted fabrics, in order to knit garments which are thus completely finished by sewing different end edges - knitted fabrics constituting the sleeves, the body and the like, for knitting a garment in the form of a finished product, and obtaining knitted fabrics having many possibilities of shaping by selecting the way to superimpose knitting loops in order to reduce the stitches and produce assembly lines in one position

suitable.

  The method comprises, during the knitting of the knitted fabrics in the form of a cylinder by a flat knitting machine, by a set of suitable rows, the application, to a predetermined loop of a suitable line, of one or more offsets towards a loop adjacent to said predetermined loop of the same rank, and from a loop of each line towards an end edge of the knitted fabric, forming an accumulated loop in which the predetermined loop and the loop adjacent to it are superimposed a suitable number of times to thereby reduce the width of the knitted fabric, and form shaping lines using the rows of loops

  accumulated formed during all the rows.

  When the knitted fabrics are knitted in the form of cylinders by a flat knitting machine having front and rear needle beds placed face to face, a suitable line loop receives a superimposed loop from the

  adjacent line, in an appropriate row.

  That is, a loop of a line adjacent to a predetermined loop towards the end of the knitted fabric is shifted to a predetermined loop of a suitable rank. This operation is carried out a number of times so that several loops are accumulated on the predetermined loop and at the same time the knitting width is reduced. Several accumulated loops are formed during the suitable row to form shaping lines. Figures 1 to 3-12 and Figures 4 to 6-19 show a first embodiment and a

  second embodiment, respectively.

  Figure 1 is a front view of a sweater knitted by a method of the present invention; Figure 2 is a view of the end portion

  right of the width of the knitted fabric.

  Figures 3-1 to 3-12 are views of the knitted fabric representing, in the order of operations, the position of the loops of the knitted fabrics placed on needles of two needle beds as well as the advance of the thread; Figure 4 is a front view of a knitted sweater by the method of the present invention; Figure 5 is a principle view of the grouping which constitutes the knitting principle applied to knit the sweater; and FIGS. 6-1 & 6-9 are views of the knitted fabric representing, in the order of operations, the position of the loops of the knitted fabrics placed on the needles

  four needle beds and representing the position of the thread.

  Embodiments of the present method will

be described below.

  The knitted fabrics to which the present invention has been applied include knitted sleeves with ruffles, raglan sleeves, etc. These knitted fabrics are knitted by a flat knitting machine comprising one or two needle beds respectively in front and

backward.

  As a first embodiment, a method for mounting a sleeve knitted fabric which knits a sweater 1 shown in FIG. 1 using a knitting machine with two needle beds comprising a front needle bed F and a rear needle bed B will be described below. The pullover 1 is knitted in the shape of a cylinder by first knitting a body part 2 separately from size 3 and sleeves 4, 4 from the bottom edge of a sleeve 5, respectively, and when the three parts have been knitted over a predetermined length, these three parts are knitted in one piece from the lower part of the armholes 6, 6, and then a shoulder 9 is knitted. As an example of the knitted fabric with sleeves that will be described later, it is explained how to make a part in which a shaping line 7 oriented upwards from the armhole 6 follows a curved part before taking a vertical direction . In the above-mentioned part of the sweater 1, the lines of the sleeves 8,8 on the right and left side of the knits are inclined, and therefore the width of the knitted fabrics should be gradually decreased. Consequently, the transfer of stitches is carried out stitch by stitch on the adjacent line in two stages to reduce the width of the knitted fabric. Thanks to this transfer of meshes, a shaping line is formed in which a part comprising two loops

  superimposed is oriented in the vertical direction.

  The knitting of knitted fabrics of knitted sleeves with mounted sleeves, the pattern of which is shown in Figure 2 will

  be described below with reference to Figure 3.

  The view of the knitted model with mounted sleeves represented in FIG. 2 corresponds to the state in which the fabrics knitted in the shape of a cylinder by needle beds

  front and rear are superimposed on the front and rear.

  The line in bold lines represents the fabric knitted by the front needle bed F, while the line in fine lines represents the fabric knitted by the rear needle bed B. The view of the model in FIG. 2 simply represents the right end part of the width of the knitted fabric, and a fabric knitted in the same manner corresponding to the left end portion is knitted symmetrically (left and right) by reverse movement of a carriage (not shown). Knitting the

  right end portion will now be described.

  Row I in Figure 2 is knitted with a needle from the front needle bed F. In Figure 3-1, threads are applied to the needles A, C, ... O, Q of the front needle needle F to knit the part knitted at the front and the carriage is inverted so that the threads are knitted by needles R, P, ... D, B of the rear needle bed B to form row II of the fabrics knitted at the back (figure 3 -2). The threads having been knitted in row II are reversed at the left end of the view of the model not shown for knitting row III of the fabrics knitted at the front. In row III, the fabrics knitted by the front needle bed are knitted, in the same way as in row I, by the needles A, C, ... O, Q of the front needle bed F (figure 3-3), and the carriage is reversed so that row IV of the fabric knitted by the rear needle bed is knitted by needles R, P, ... D of the rear needle bed B in the same way as row II (figure 3-4). Then, the width of the knitting is reduced by one stitch every four rows from row III and row IV (every two rows in the case where the fabrics knitted by the front and rear needle beds are developed). That is, a row IV loop placed on needles B, D, F,

26439-17

  and H from the rear needle bed B is transferred to the

  needles B, D, F and H of the front needle bed F (Figure 3-5).

  The row III loop placed on needles K, M, O, Q of the front needle bed F is transferred to the needles K, M, O, Q of the rear needle bed B (Figure 3-6). In this state, the rear needle bed B. is shifted by two needles to the left so that the needles A, B, ... X of the front needle bed F are opposite the hands C, D, ... Z of the rear needle bed B (Figure 3-7). The row IV loop placed on the needles L, N, P, R of the rear needle bed B is transferred to the needles J, L, N, P of the front needle bed F, and the row III loop transferred to the needles K , M, O, Q of the rear needle bed B is transferred back to needles I, K, M, 0 of the front needle bed F. Consequently, the loop of needles K, M, O, Q of the front needle bed F of the row III is moved to the adjacent needles I, K, M, 0 and therefore the loop of needle K is superimposed on the mouth of needle I (Figure 3-8). It is a superposition of loops indicated in 71, that is to say an accumulation of loops, and part of the line of

  shaping 7 of the knitted fabric at the front is thus formed.

  Then, the offset is reversed so that the needles K to Z of the front needle bed F and the rear needle bed B are placed face to face (Figure 3-9), and that the row IV loop transferred to the needles B, D, N, P of the front needle bed F is brought back to needles B, D, ... N, P of the rear needle bed B (figure 3-10). The row IV loop placed on the needles L, N, P, R of the rear needle bed B is moved to the needles J, L, N, P and consequently, the loop of needle L is superimposed on the loop of needle J. This overlapping loop is shown at 72 in FIG. 2 ,. and a line for shaping the knitted fabric to

  the rear, not shown, is thus formed.

  Then row V of the knitted fabric on the front is knitted using needles A, C, ... N, O of the front needle bed F (Figure 3-11) and row VI of the knitted fabric on the back is knitted by needles P, N, ... D, B of the rear needle bed B (figure 3-12>. After knitting row VI, rows VII and VIII are knitted in the same way as rows III and IV , the operations of figures 3-3 & 3-12 are repeated for knitting. The loop is transferred and the loops are accumulated and the 1st width of the knit decreased in a similar manner to what has been described above (the view of the knitting has been omitted.) As a second embodiment, an embodiment method for knitting a sweater 101 shown in Figure 4 using a four needle knitting machine comprising front needle beds FU, FD and rear needle beds BU, BD will now be described. A shaping line formed by the principle of assembly is indicated in 102. The model of this part is shown in Figure 5. The knitting of the knitted fabric assembly shown in the view of the model in Figure 5 is described below with reference to Figure 6. The view of the principle of the assembly shown in Figure 5 shows the state in which the fabrics knitted in front and back in the shape of a cylinder by the front and rear needle beds are developed.-The line in bold line represents the fabric 103 knitted with front by the upper and lower front needle beds FU, FD and the thin line represents the fabric 104 knitted back by the upper and lower rear needle beds BU, BD. The transfer of the stitches of the knitted fabrics 103 and 104 is carried out to the adjacent line every two stitches

  and every other row to decrease the width of the knitting.

  -Thanks to this transfer of meshes, a shaping line 102 is formed according to which a part comprising three

  superimposed loops is oriented obliquely.

  Row I of Figure 5 is knitted by the needles of the lower front needle bed D. In Figure 6-1, threads are applied to needles B, C, ... J, K of the lower front needle needle bed FD for knitting fabrics knitted by front needle beds, and the carriage is inverted so that the threads are knitted by needles K, J, ... C, B of the lower rear needle bed BD to form row II of the knitted fabric rear (Figure 6-2). In row III, after knitting in row II, the fabric knitted in front is knitted in the same way as row I by needles B, C, ... J, K of the lower front needle bed FD (figure 6-3 ), and then the carriage is inverted so that row IV of the fabric knitted back is knitted by needles K, J, ... C, B of the lower rear seam BD in the same way as row II (figure 6-4). The knitting width is thus reduced by two stitches in each row at the same time on the front and rear sides of the following rows V and VI. The reduction in the width of knitting is carried out as follows: that is to say, the row II loop placed on needle H of the lower front needle bed FB is transferred to the needle h of the needle bed upper rear BU (Figure 6-5). Then, an offset of the upper and lower rear needle beds BU, BD is made one mesh to the left (Figure 6-6), and the

  row III loop found on needles B, C, ...

  F, G of the lower front needle bed FD is transferred to needles c, d, ... g, h of the upper rear needle bed BU (Figure 6-7). Then, an offset of the upper and lower rear needle beds BU, BD is made with one stitch to the right and the row III loop located on needles c, d, ... g, h of the upper rear needle bed BU is transferred to needles C, D, ... G, H of the lower front needle bed FD (figure 6-8). In this way, in the principle view represented in FIG. 5, a double loop is formed simply on a line H at row V, and the knitting width is reduced by one stitch. The principle shown shows that at row V, the knitting width is further reduced by one stitch (two stitches in total), but a reduction of one stitch is still made at row V after the knitting width has been reduced. row VI in the back knitted fabric (represented by the thin line). That is, a shift of the superimposed loops of the knitted fabrics in front and in

  reverse is performed alternately.

  Then, during row IV of the knitted fabric on the back, the knitting width is reduced by one stitch. The row IV loop located on needle H of the lower rear needle bed BD is transferred to needle h of the upper front needle bed FU (Figure 6-9). Then, an offset of the upper and lower rear needle beds BU, BD is made with one stitch to the right (Figure 6-10) and the row IV loop located on needles B, C, .... F, G back needle

  lower BD is transferred to needles c, d, ...

  g, h of the upper front bed FU (Figure 6-11).

  Then, an offset of the upper and lower front needle beds FU, FD is made with one stitch to the left, and the row IV loop located on needles c, d, ... g, h of the upper front needle bed FU is transferred to needles C, D, ... H of the lower rear needle bed BD (figure 6-12). Consequently, in the principle view represented in FIG. 5, a double loop is formed simply on a line H at row VI, and the knitting width is reduced by one stitch. In the drawing shown, it is shown that at row VI, the knitting width is further reduced by one stitch (two stitches in total), but a decrease of one stitch is still made at row VI after the other decrease in the knitting width of the

  row V on the front (shown in bold line).

  Then, another decrease in mesh of the line

  H of row V of the knitted fabric in front will be described.

  By moving the carriage to the right, the

  row III loop on needles C, D, ...

  F, G of the lower front needle bed FD is transferred to needles c, d, ... f, g of the upper rear needle bed BU (Figure 6-13). Then, an offset of the upper and lower rear needle beds BU, BD is made of a mesh to the right (Figure 6-14), and the

  row III loop on needles c, d, ...

  g, h of the upper rear needle bed BU is transferred to needles D, E, ... G, H of the lower front needle bed FD (figure 6-15). Consequently, on the principle view represented in FIG. 5, a triple loop is formed simply on the line H during row V

  and the knitting width is reduced by two stitches.

  Then knitting the knitted fabric on the back

continues.

  That is to say, the row VI loop located on needles C, D ,.

  F, G of the lower rear seam BD will be subjected to a shift of one stitch to the right to be transferred to needles d, e, ... DTD: f, g of the upper front seam FU (figure -6 -16). The offset of the upper and lower rear needle beds BU, BD is carried out with one stitch to the left and the row III loop located on needles D, E, ... G, H of the upper front needle bed FU is transferred to needles d, e, ... g, h of the needle bed..DTD: lower back BD (figure 6-17).

  Therefore, a triple loop is formed on line H of rows V and VII for both the knitted fabric there at the front and at the back, and the knitted fabric is

  decreased by two stitches in knitting width.

  Then, the knitting of rows VII and VIII is carried out. Row VII is knitted by applying threads on needles D, E, ... J, K of the lower front needle bed (figure 6-18), and the carriage is reversed so as to place threads on needles K, J, ... E, D of the lower back seam BD in order to knit the

row VIII (figure 6-19).

  The knitting explained above is repeated for

rows IX and X in figure 5.

  The knitted fabric can be reduced in an adjustable manner in knitting width according to the extent of the accumulation of the loops at the points of accumulation of the loops 171, 172, 173, 174 ... of the rows of knitting width reduced by the process of knitting above and according to the number of lines on which loops

are accumulated.

  The rows of said loop accumulation points, namely, 71, 73, ... and 171, 173 for the knitted fabric at the front, and 72, 74, ... 172, 174 for the knitted fabric at the back constitute the shaping lines 7 and 102. Thus, if the accumulation of said loops is performed to form on the same lines, the shaping lines 7 and 102 constitute a vertical and rectilinear line. In a case where the lines produced are successively shifted to the next, the lines of

  shaping are formed obliquely.

  The present invention employs the method which has been described above. In the production of knitted fabrics in the shape of a cylinder for which during the knitting process the knitting width is reduced, no sewing work is necessary, the shaping lines formed by knitting which are oriented with the The desired angle and the desired length can be produced by changing the order of movement of the loops, the rate of decrease of the stitches on the rows or lines, the number of stitches transferred and the number of transfers.
