In the knitted fabric provided with the cylindrical knitted part knitted by the flat knitting machine provided with the said prior needle drum, there existed a problem as shown below.

In the vicinity of the closed end of the cylindrical knitted portion, there is also a pseudo-stitch train and no clogged stitches. In addition, when the knitted fabric is used, since the pseudo stitch string is a boundary between the front and back knit fabric portions, there is a possibility that the knitting yarn constituting the pseudo stitch string is pulled by the front and back knitted fabric portions, thereby being damaged.

The present invention has been made in view of the above circumstances, and an object thereof is provided with a needle tip drum which can be knitted so that the interval of each stitch is blocked at the closed end side in order to reinforce the closed end side of the cylindrical knitted portion provided in the knitted fabric. It is an object of the present invention to provide a knitted fabric comprising a flat knitting machine and a tubular knitted portion knitted by the flat knitting machine.

The present invention includes a pair of front and rear needle beds and a pair of needle drums corresponding to each needle bed, and are paralleled in two directions of the needle drums. A plurality of needle needles, which are installed side by side on the needle bed by the projections, are needle-selected, one end is closed, and the other end is opened. The present invention relates to a flat knitting machine for knitting a knitted fabric provided with a tubular knitted portion. The needle needle drum provided in this flat knitting machine includes an initial knitting protrusion, a draw-off knitting protrusion, and an incremental knitting protrusion. It is done. The initial knitting projection portion pinches a knitting needle corresponding to the knitting width of the initial knitting portion, which becomes the closed end of the cylindrical knitting portion. The draw-off knitting protrusion part is paralleled in multiple numbers adjacently in the circumferential direction of an initial knitting protrusion part and a pin needle drum, and pinches a knitting needle within the knitting width of an initial knitting part. The incremental knitting projections are pinned in such a manner that the plurality of parallel knitting projections are parallel to and adjacent to each other in the circumferential direction of the draw-off knitting projection portion and the pin needle drum so that the knitting width is sequentially increased from the knitting width smaller than the knitting width of the initial knitting portion. Then, the first drawoff knitting protrusion is selected by n (n is an integer equal to or greater than 1), and the remaining drawoff knitting protrusion is selected by the first knitting off protrusion. Pick up.

As one example of the flat knitting machine of the present invention, the draw-off knitting protrusions may be paralleled with n + 1 adjacent to the circumferential direction of the needle needle drum. In this case, the m + 1 (m is n or less and an integer equal to or greater than 1) th drawoff knitting projection calculated from the initial knitting projection portion selects the knitting needle that is not preempted in the mth drawoff knitting projection portion. In particular, n is preferably 1.

As one example of the flat knitting machine of the present invention, the needle needle drum has a plurality of coupling grooves extending along the axial direction of the needle needle drum on its surface and parallel to the circumferential direction. And a needle pin inserted into the coupling groove. In this case, the initial knitting projection and the incremental knitting projection are composed of one needle pin or a combination of a plurality of needle needles in which a plurality of needles are collectively arranged, and a draw-off knitting protrusion is one needle needle. It consists of an aggregate of the needle pins.

On the other hand, the knitted fabric of this invention is equipped with the cylindrical knitted part which has the one end closed, the other end opened, and the front and back knitted fabric part knitted initially from the closed end side, The cylindrical knitted part is initial stage A knitting part, a draw-off knitting part, and a knitting width increasing part are provided. The initial knitting portion connects the front and rear knitted fabric portions, and also has a similar stitch row to form a base for forming the front and back knitted fabric portions, and at least one similar stitch on the front and back knitted fabric portion side. It consists of a starting stitch row (始 端 stitch 列) consisting of a new stitch following each similar stitch in the row. The draw-off knitting portion includes a first course of stitches formed of new stitches following every other n (where n is an integer of 1 or more) stitches in the end of the initial knitting portion parallel to the opening end side; And a stitch row of one or more courses consisting of a new stitch following the stitch of the stitch row of the end where the stitch row of the first course is not formed. The knitted width increasing portion is formed of a stitch sequence of a plurality of courses that are connected to the stitch row of the draw-off knitted portion and directed toward the opening end side, and is opened from the closed end side. The knitting width of the stitch row gradually increases toward the side.

As one example of the knitted fabric of the present invention, the draw-off knitted portion is preferably made of a stitch row of n + 1 course. In particular, n is preferably 1.

As one example of the knitted fabric of the present invention, it is preferable that the front and rear knitted fabric portions in the cylindrical knitted portion are pile knitted fabrics. The pile knit fabric can be knitted by a well-known knitting technique. For example, as described in Japanese Patent Application Laid-Open No. 60-59333, a yarn feeder for yarn feeding a base yarn serving as a base of a knitted fabric portion, and a knitted fabric portion The yarn feeder for feeding the yarn knitting yarn to be the pile portion may be operated at the same time for knitting.

According to the flat knitting machine provided with the pin needle drum of this invention, the knitted fabric of this invention provided with the initial knitted part, the draw-off knitted part, and the cylindrical knitted part with a knitted width increase part can be knitted. According to this knitted fabric, miss yarns of different stitching rows are formed so that the stitch spacing in each stitching row formed by applying miss knitting at the draw-off knitting portion is blocked and overlaps the stitches of the arbitrary stitching rows. Since it is arrange | positioned, the closed end of a cylindrical knitted part is reinforced.

Further, when n + 1 drawoff knitting projections are formed, a knit fabric having a tubular knitting portion having a drawoff knitting portion formed of a stitch row of n + 1 courses can be knitted. As a result, the knitted fabric provided with the cylindrical knitted part which was excellent in the beauty and intensity | strength was closed because the space | interval of each stitch was blocked in the vicinity of the closed end part of the cylindrical knitted part. In particular, when n is 1, the draw-off knitting portion is composed of two courses of stitches, and each stitch of the second course of stitches is disposed between adjacent stitches of the first course of stitches, and the cylindrical knitting portion having the best beauty and strength is arranged. do.

In the knitted fabric of the present invention, even when the front and back knitted fabric portions are pile knitted fabrics, similar stitch rows that are not piled are hardly visible. In a normal case, when the front and back knit fabric portions are pile knit fabrics, the pseudo-stitch strings are visible because they cannot be piled. However, in the knitted fabric of the present invention, since the pile stitch spacing in the vicinity of the closed end is clogged, the pseudo stitch rows are hardly visible.

In the following, an embodiment of the present invention will be described taking as an example the knitting of a glove (knitting fabric) having five finger portions (cylindrical knitting portions). In this embodiment, a flat knitting machine is used for needle knitting a needle needle, which is provided side by side in a front and rear needle bed, by a needle drum. It was.

One needle drum is provided in each of the front and rear needle beds. On the outer circumferential surface of the needle needle drum, a plurality of coupling grooves extending along the axial direction of the needle needle drum are arranged in parallel in the circumferential direction of the needle needle drum. A needle pin is inserted into each of the coupling grooves, and needle needles of the needles are performed by the needle pins (protrusions). The number of engaging grooves formed in the needle needle drum can be appropriately changed depending on the form of the knitted fabric to be knitted. In the case of increasing or decreasing the number of engaging grooves, the diameter of the pin needle drum may be changed in accordance with the number.

1 is an exploded view of a needle drum showing the arrangement of the needle pins corresponding to the front needle bed. Moreover, although the expanded view of the needle needle drum corresponding to the back needle bed is not shown, the arrangement state of this needle needle pin is line symmetry of FIG. However, since the knitting width required by the front and rear knitted fabric portions varies depending on the shape of a human finger, the length of some of the needle pins is different from that in FIG.

In the left and right ends of Fig. 1, the numbers on the vertical axis correspond to the coupling grooves (lines) formed in the needle needle drum, and the numbers on the horizontal axis on the upper and lower ends indicate the needle needles that are pinched. Corresponds to the location. When knitting gloves, they are used in order from the needle pins arranged in line 1. Lines 1 to 8 correspond to the knitting of the little finger part, hereinafter, lines 9 to 17 are the knitting of the ring finger finger part, lines 18 to 26 are the knitting of the middle finger part, and lines 27 to 34 are the index finger part Knitting, Lines 35 and 36 consist of four bodies, Lines 37 through 45 comprise the thumb portion, Line 46 consists of five bodies using knitted yarns containing elastic yarn, 47 Line No. 1 corresponds to the knitting of an empty course for moving an unused yarn of rubber yarn out of the knitting width, and Line 48 corresponds to the knitting of an insertion hole of a hand. The numerical value in the square shown on the horizontal line of the needle pin in each line shows the number of knitting needles pinned in the line.

In the needle tip pin corresponding to the knitting of each finger part except the thumb part, the needle tip of the line with the smallest number is the initial knitting protrusion part, and the following two line needle pins are the draw-off knitting protrusion part (draw-). The off pins of the other lines except the off line and the line with the highest number are the incremental knitting projections (漸增 編成 突起 部). In the needle pin corresponding to the thumb, the needle pin of line 37 is the initial knitting protrusion, the needle pin of lines 38 and 39 is the draw-off knitting protrusion, and the needle pin of lines 40 to 43 is the incremental knitting protrusion, 44 The needle pin of the bun is a projection for overlapping the forked finger. The pin needle constituting the draw-off knitting protrusion is a short pin having a width only for pinching one single needle, and the pin needle constituting the other stone base is a long pin that pins a plurality of needles collectively.長 尺 材). Alternatively, a plurality of needle pins may be connected instead of the long needle pins.

Here, the arrangement of the conventional needle pin is shown in FIG. 3 for comparison. The method of seeing FIG. 3 is the same as that of FIG. When comparing Fig. 3 which is a conventional product with Fig. 1 according to this embodiment, the needle drum of Fig. 3 does not correspond to the draw-off knitting protrusion in the needle drum of Fig. 1, only the initial knitting protrusion and the incremental knitting protrusion. Is formed.

Next, the actual knitting procedure made by using the above-described needle needle drum will be described with the pinky finger as an example. Fig. 2 is a diagram of a knitting process showing the knitting procedure of the little finger part, in which the number in the left column indicates the knitting process number (hereinafter referred to as S + number) for one round trip of a carriage. The arrow in the right column indicates the moving direction of the carriage. In addition, the middle side column in FIG. 2 shows the state of stitch formation in each knitting process, and the front side is parallel to the lower side among the black circles which are arranged in parallel with each other. The needle of the needle bed (front needle bed), which is parallel to the upper side, is the needle of the back needle bed.

First, the needle needle corresponding to the knitting width of the pinky finger portion is pinched by the needle pin (initial knitting protrusion) of line 1 in FIG. And loop hooked by the knitting needle alternately in the knitting of the front and rear needle beds in the forward knitting of S1, and all the hooks formed in the front needle bed by the forward knitting in the reverse knitting of S1. A new stitch (start stitch) is formed following the loop. The latch loop formed by the forward knitting is a base end forming the front and rear knitted fabric portions of the pinky finger portion, and when separated from the needle bed, it becomes a pseudo stitch string connecting the front and rear knitted fabric portions. In addition, the start stitch string formed by the start stitch formed by reverse knitting improves the beauty of the finished finger portion. Of course, the starting stitch row may be formed by the rear needle beds, or may be formed by the front and rear needle beds.

Next, the needle needle drum is rotated to change from the needle needle pin of line 1 to the needle needle pin (draw-off knitting portion) of line 2 to perform reciprocating knitting of S2. This combination of S2 forms a new stitch that is followed by a similar stitch every other row in the stitches of the stitches in the rear needle bed, and a new stitch is formed that is successively stitched in the beginning stitch rows in the front needle beds.

In addition, the line needle pin of line 2 is changed from the line needle pin (draw-off knitting protrusion) of line 3 to perform reciprocation of S3. This knitting of S3 forms a new stitch following the similar stitch without stitch formation in the knitting of S2 in the rear needle bed, and a new stitch following the starting stitch without stitch formation in the knitting of S2 in the front needle bed. Is formed. The draw-off knitted part is formed by knitting of these S2 * S3.

Subsequently, the reciprocating knitting shown in S4 to S7 is performed. The knitting of S4 to S7 is knitted by using the knitting needle that has been needled by the needle pin (increase knitting protrusion) of line 4 to 7 in FIG. The knitting of these S4 to S7 may be repeated several times, and in this case, the carriage is knitted without moving the needle drum. By the knitting of these S4 to S7, as the number of knitting courses advances in the little finger part, a knitting width increasing part is formed in which the knitting width of the stitch row gradually increases.

Afterwards, the reciprocating knitting shown in S7 is performed by the length of the pinky part required, and the reciprocating knitting shown in S8 is finally used in order to use a stitch holder. The knitting of S8 is made by knitting needles that have been needled using the needle needle of line 8 in FIG.

In a portion where knitting widths such as lines 8 and 9 overlap, the knitting may be performed while the stitches are suppressed using a stitch holder (for example, see Japanese Patent Laid-Open No. 2000-220064).

When the pinking is finished, the needle drum is rotated forward and the line shown in FIG. 1 is changed to change the line shown in FIG. 1, so that the ring finger, the middle finger, the index finger, four trunks, and the thumb Organize dogs in order of insertion and insertion. The knitting of these fingers and the body is made by knitting needles picked by the needle pins of each line in the same manner as the knitting of the little finger portions described above.

Each finger part explained above is provided with the draw-off knitting part formed in the closed end side, Each stitch of this draw-off knitting part is connected to every other stitch in the initial knitting part, and is newly made. Because it is formed, the gap is in a closed state. In addition, the space | interval of each stitch in the knitting width increase part following this draw-off knitting part is also blocked. As a result, the thickness at the closed end of the finger portion increases and the elongation of the knitting yarn decreases, so that the portion is reinforced. Also, in the draw-off knitting, the closed end of the finger portion is reinforced even when a miss yarn is disposed so as to overlap the knit stitch.

In addition, in work gloves and the like, the tip portion of the finger may be immersed in a coating agent. However, in the past, the coating agent penetrates into the inside of the glove, thereby impairing the feeling of wearing the glove. On the other hand, in the glove of this embodiment, since the stitch interval near the tip of the finger portion is blocked, penetration of the coating agent can be suppressed.

(Other Examples)

The combination of S2 and S3 shown in FIG. 2 may be repeated several times. For example, S1? S2? S3? S2? S3? S4 (same as FIG. 2 after S4). In order to perform such knitting, a draw-off knitting projection portion comprising line needle pins in the same arrangement as Line 2 and Line 3 may be added between Line 3 and Line 4 shown in FIG. In this case, the incremental knitting protrusion may be reduced by the additional drawoff knitting protrusion without increasing the line, or may be coped by increasing the line by increasing the diameter of the needle drum. In addition, the arrangement of the needle tip pins is similar to that of Fig. 1, and the needle needle drum is reversely rotated to form the second S2 by the needle needle pin of the second line. The second needle pin may be used to knit the second S3.

In addition, in forming the draw-off knitted part in a finger part, you may enlarge the adjacent stitch space in a stitch row. For example, the drawoff knitting protrusion may be configured so that the needle needle is picked every other needle. At this time, it is preferable that the needle needle which is not selected in the first draw-off knitting is made to be picked out by the second and subsequent draw-off knitting. For example, both the needles that are not preempted in the second draw-off knitting and the first draw-off knitting are selected. Alternatively, a part of the knitting needles not preempted in the first drawoff knitting is picked up in the second drawoff knitting, and the rest is picked out in the third drawoff knitting.

The needle drum may have a configuration in which an approximately circular arc-shaped cam plate is inserted into a coupling groove extending in the circumferential direction of the needle drum, and the needle is needled by the cam portion of the cam plate protruding from the needle drum (for example, See Patent Document 2). In this case, the assembly of cam parts parallel to the axial direction of the needle needle drum among the cam parts provided in the plurality of cam plates respectively corresponds to the protrusions in the present invention. In addition, you may process a processus | protrusion part integrally with a pin needle drum.

In addition, this invention is not limited to the above-mentioned Example, It can change suitably in the range which does not deviate from the summary of this invention. For example, you may change the ratio which increases the knitting width of each finger part. The knitted fabric to be knitted may be provided with a cylindrical knitted section in which one end is closed and the other end is opened. For example, the front part is a round socks or 5 It may be a sock with a toe of dogs or a bag of cloth shape.
