In addition, when the knitted fabric is used, since the similar stitch row is the boundary (boundary) of the front and rear knitted fabric parts, there is a possibility that the knitting yarn constituting the similar stitch row is pulled by the front and rear knitted fabric parts.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and has an object to provide a fastener drum which can be knitted such that the intervals of respective stitches are clogged on the side of a closed end in order to reinforce a closed end side of a tubular knitted part provided in a knitted fabric A flat knitting machine and a tubular knitting section knitted by the flat knitting machine.

The present invention is characterized in that a pair of front and rear needle beds and a pair of needle selection drums corresponding to the needle beds are arranged in parallel to each other in the circumferential direction of the needle selection drums A part of a plurality of knitting needles arranged side by side on the needle bed by a protruding portion is needle-selected so that one end is closed and the other end is opened, The present invention relates to a weft knitting machine for knitting a knitted fabric having a barrel-shaped knitted fabric portion which is formed into a tubular knitted fabric. The needle bar provided in the flat knitting machine is characterized by having an initial knitting protruding portion (initial knitting protruding portion), a draw-off knitting protruding portion, and an increasing knitted protruding portion (gradually increasing knitting protruding portion) . The initial knitted fabric protrudes a knitted fabric corresponding to a knitted fabric width (knitting width) of an initial knitted fabric portion which becomes a closed end of the tubular knitted fabric. A plurality of draw-off knob projections are adjacently arranged adjacent to each other in the circumferential direction of the needle knitting drum and the knitted fabric protruding portion, and the knitting needle is stitched within the knitting width of the knitted fabric. The incremental knitting protrusions are arranged in plural in parallel in the circumferential direction of the draw-off knob protruding portion and in the circumferential direction of the needle bar, and the knitting needle is stitched so that the knitting width is sequentially increased from the knitting width smaller than the knitting width of the initial knitted portion. The first draw-off knitting protruding portion is formed by n (n is an integer of 1 or more) knitting needles, and the remaining draw-off knitting protruding portion is formed by the first knitted fabric protruding portion, I will do my best.

As one example of the weft knitting machine of the present invention, the draw-off knurled protrusions may be arranged in n + 1 adjacently in the circumferential direction of the predetermined drum. In this case, the draw-off knitted protruding portion of m + 1th (m is an integer equal to or smaller than n and not less than 1) calculated from the initial knitted protruding portion touches the knitted fabric which has not been tilted at the m-th draw- off knitted protruding portion. Particularly, n is preferably 1.

As one example of the flat knitting machine of the present invention, the throat drum has a plurality of engaging grooves (coupling grooves) extending in the axial direction (axial direction) of the throat drum and parallel to the circumferential direction, And a needle selection pin inserted into the coupling groove. In this case, the initial knitted protruding portion and the incremental knitted protruding portion are constituted by a connecting body of a single needle pin or a plurality of needle pins for collectively collecting a plurality of needle marks, and the draw- And a plurality of needle pins are collectively formed.

On the other hand, the knitted fabric of the present invention has a tubular knitted part having one end closed and the other end opened and having front and rear knitted fabric parts initially knitted from the closed end side, and the tubular knitted part has an initial A knitting portion, a draw-off knitting portion, and a knitting width increasing portion. The initial knitting section includes a similar stitch row (a similar stitch row) serving as a base end for forming front and rear knitting needles, and a similar stitch row at least on the front and back knitting aids side, And a start stitch row (start end stitch row) composed of new stitches following each similar stitch in a row. The draw-off knitting section includes a stitch row of a first course consisting of a new stitch followed by n (where n is an integer of 1 or more) stitches in a stitch row of an end portion of the initial knitting section side by side on the opening end side, And a new stitch succeeding to the stitch row of the stitch row at the end where the stitch row of the first course is not formed. The knitting width increasing portion is formed of a plurality of courses of stitch rows extending from the stitch row of the draw-off knitting portion toward the opening end side, and the knitting width increasing portion is provided with an opening end from the closed end side, (Knitting width) of the stitch row gradually increases toward the side of the stitch row.

As an example of the knitted fabric of the present invention, it is preferable that the draw-off knitting portion is made up of stitch rows of n + 1 courses. Particularly, n is preferably 1.

As one example of the knitted fabric of the present invention, it is preferable that the front and rear knitting needles in the tubular knitted part are pile knitted fabrics. The file knitting fabric can be knitted by a known knitting technique. For example, as disclosed in Japanese Patent Publication No. 60-59333, there are provided a yarn feeder for feeding yarn to a base yarn serving as a base of a knitting needles, It is preferable that the yarn feeder for feeding the pile yarn as a pile portion is simultaneously operated and knitted.

According to the flat knitting machine of the present invention, it is possible to knit the knitted fabric of the present invention having the initial knitted portion, the draw-off knitted portion, and the tubular knitted portion provided with the knitted width increasing portion. According to this knitted fabric, the stitch spacing in each stitch row knitted by applying miss knitting in the draw-off knitting section is blocked, and a miss yarn of another stitch row is overlapped with the stitch of an arbitrary stitch row So that the closed end of the tubular knitted portion is reinforced.

Further, if n + 1 draw-off knurled protrusions are formed, a knitted fabric having a tubular knitted portion having a draw-off knitted portion made up of stitch rows of n + 1 courses can be knitted. As a result, the knitted fabric is provided with the tubular knitted portion having excellent strength even when the intervals of the stitches are close to each other in the vicinity of the closed end of the tubular knitted portion. In particular, when n is 1, the draw-off knitting portion is constituted by two rows of stitch rows, and each stitch of the second row of stitch rows is arranged between adjacent stitches of the first row of stitch rows. do.

Further, in the knitted fabric of the present invention, even if the front and rear knitting needles are made into a pile knitting fabric, a similar stitch row that is not pile-knitted is hard to be seen. In a normal case, if the front and rear knitting aspirations are made into a pile knitting fabric, the similar stitch row can be seen because the pile can not be knitted. However, in the knitted fabric of the present invention, the pile stitch interval in the vicinity of the closed end is clogged, so that the similar stitch row is hard to be seen.

Hereinafter, an embodiment of the present invention will be described by taking as an example the knitting of a glove (a knitted fabric) having five fingers (a tubular knitted portion). In this embodiment, a knitting machine is used in which needle knitting needles arranged side by side on the front and rear needle beds are needle-sectioned by a needle selection drum. Respectively.

The throat drum is installed in each of the front and rear needle beds one by one. A plurality of engaging grooves extending in the axial direction (axial direction) of the predetermined drum are juxtaposed in the circumferential direction of the predetermined drum on the outer peripheral surface of the predetermined drum. In each of the engaging grooves, a needle selection pin is inserted, and needle selection of the knitting needles is performed by the needle pins (protrusions). Further, the number of the engaging grooves formed in the fastener drum can be appropriately changed in accordance with the shape of the knitted fabric to be knitted. When the number of engaging grooves is increased or decreased, the diameter of the predetermined drum may be changed in accordance with the number of engaging grooves.

1 is an exploded view of a throat drum showing the arrangement of the needle pins corresponding to the front needle bed. Further, although an exploded view of the throat drum corresponding to the back needle bed is not shown, the arrangement of the throat pins is such that Fig. 1 is line-symmetrical up and down. However, the knitting width (knitting width) required at the front and rear knitting needles differs depending on the shape of a person's finger, so that the length of some of the needle pins differs from that of Fig.

The numbers on the vertical axis at the left and right ends (left and right ends) of Fig. 1 correspond to the engaging grooves (lines) formed in the throat drum, and the numbers appearing on the horizontal axis at the upper and lower ends Position. When gloves are knitted, they are used in order from the needle pins arranged on line 1. [ The lines 1 to 8 correspond to the knitting of the little finger, the lines 9 to 17 are the knitting of the weak finger, the lines 18 to 26 are the knitting of the stop finger, and the lines 27 to 34 correspond to the knitting of the index finger Knitting, the knitting of the four fingers on the lines 35 and 36, the knitting of the thumb on the knitting lines 37 to 45, the knitting of the five bodies using the knitting yarn including the elastic yarn on the line 46, 47 Line corresponds to the knitting of an empty course for moving the unused rubber yarn feeder out of the knitting width, and line 48 corresponds to the knitting of the hand entrance. In each line, the numerical value in the square shown on the lateral side of the needle pin indicates the number of knitting needles to be stapled in the line.

The needle pins corresponding to the knitting of the respective fingers except for the thumb, the needle pins of the smallest number are the initial knitted protrusions (initial knitting protrusions), the succeeding two line needle pins are the draw-off knitting protrusions, off knitting protrusions), and the remaining pins of the remaining lines except for the line having the greatest number are the gradually increasing knitting protrusions. In the needle pin corresponding to the thumb portion, the needle pin of the line 37 is the initial knitted protruding portion, the needle pins of the lines 38 and 39 are the draw-off knitting protrusions, the needle pins of the lines 40 to 43 are the increasing knitting protrusions, Is a projecting part for overlapping a fingertip part. The needlepoint forming the protruding portion of the draw-off knitted fabric is a short material having a width only for stapling one knitting needle. The needle pin constituting the other protruding portion is made of a long material Long material). Alternatively, a plurality of needle pins may be connected in place of the long needle pins.

Here, the arrangement of the conventional needle pins for comparison is shown in Fig. The method of FIG. 3 is the same as that of FIG. 3, which is a conventional product, is compared with Fig. 1 of the present embodiment. In the throttling drum of Fig. 3, there is no equivalent to the draw-off knitting protrusion of the throat drum of Fig. 1, and only the initial knitting protrusion and the incrementally- Respectively.

Next, the actual knitting sequence using the above-mentioned throat drum will be described by taking the small finger portion as an example. Fig. 2 is a drawing of a knitting process showing the knitting sequence of the little finger portions. The number in the left column indicates the number of knitting processes (hereinafter, S + numerals) in which the carriage is reciprocated once, The arrows in the right column indicate the direction of movement of the carriage. The intermediate side in Fig. 2 represents the stitch formation state in each knitting step. In the black side circles arranged vertically and facing each other in parallel, The knitting needle of the front needle bed, and the knitting needle of the back needle bed which are arranged on the upper side.

First, the knitting needle corresponding to the knitting width of the small finger portion is stapled by the needle pin (initial knitting protruding portion) of the first line in Fig. In addition, in the forward direction knitting of S1, a loop hooked by the knitting needle is formed on the knitting needles of the front and back needle beds, and all the hooks formed on the front needle bed by the forward knitting in the backward knitting of S1 And a new stitch (start stitch) following the loop is formed. The latching loop formed by the forward knitting is a base end forming the front and rear knitted embossed portions of the little finger portion, and becomes a similar stitch row (similar stitch row) connecting the front and rear knitted fabric portions when separated from the needle bed. In addition, the starter stitch string made of the starter stitch formed by the reverse (backward) knitting improves the beauty of the finished fingers. Of course, the initial stitch sequence may be formed by the back needle bed, or by the front and back needle beds.

Next, the needle drum is rotated to change from the needle pin of the first line to the needle pin of the second line (draw-off knob projection), thereby performing the reciprocating knitting of S2. By this knitting of S2, new stitches succeeding the similar stitch are formed one by one in the similar stitch row in the back needle bed, and new stitches are formed in the front needle bed one after another in the leading stitch row.

Further, from the needle pin of the second line to the needle pin of the third line (draw-off knob protruding portion), the reciprocating knitting of S3 is performed. By this knitting of S3, a new stitch succeeding to the stitch-like stitch which is not stitched in the knitting of the back needle bed S2 is formed, and a new stitch succeeding to the stitch stitch formed in the knitting of S2 in the front needle bed, . A draw-off knitted portion is formed by the knitting of S2 and S3.

Then, the reciprocating knitting shown in S4 to S7 is performed. The knitting of S4 to S7 is knitted by using the knitting needles stitched by the needle pins (incremental knitting protrusions) on lines 4 to 7 in Fig. These S4 to S7 knitting may be performed each time, and in this case, the carriage is moved without knitting the rotation of the predetermined drum to knit. As a result of the knitting of S4 to S7, a knitting width increasing portion (knitting width increasing portion) in which the knitting width of the stitch row gradually increases as the number of knitting courses in the little finger portion progresses.

Then, the reciprocating knitting shown in S7 is performed by the length of the small finger portion required later, and the reciprocating knitting shown in S8 is performed in order to use the stitch holder at the end. The knitting of S8 is performed by the knitting needle finely stitched using the needle pin of line 8 in Fig.

In addition, in a portion where the knitting widths overlap with the line 8 and the knitting line 9, knitting may be performed while suppressing the stitch by using a stitch holder (for example, see Japanese Unexamined Patent Application Publication No. 2000-220064).

When the knitting of the little finger is finished, the needle drum is rotated in a normal direction to change the line shown in Fig. 1 to thereby form a ring finger finger, stop finger part, index finger part, four bodies, thumb part, It is organized in order of the dog body and the insertion port. The knitting of these fingers and the body is performed by the knitting needle finely smoothened by the needle pins of each line in the same manner as the knitting of the little finger described above.

Each of the above-described fingers has a draw-off knitted portion formed on the closed end side thereof. Each of the stitches of the draw-off knitted portion is connected to every other stitch in the initial knitted portion, So that the gap becomes clogged. Further, the interval of each stitch in the knitting width increasing portion following the draw-off knitting portion is also clogged. As a result, the thickness of the closed end of the finger portion is increased and the elongation of the knitting yarn is reduced, so that the portion is reinforced. In addition, in the draw-off knitting, the closing end of the finger portion is reinforced by disposing a miss yarn so as to overlap the knit stitch.

In addition, there are cases where the tip of the finger is immersed in a coating agent in a work glove or the like, but in the past, the coating agent penetrated into the inside of the glove, which sometimes compromised the wearing comfort of the glove. On the other hand, in the gloves of this embodiment, since the stitch interval near the tip of the finger is blocked, penetration of the coating agent can be suppressed.

(Other Embodiments)

The combination of S2 and S3 shown in Fig. 2 may be repeated several times. For example, S1? S2? S3? S2? S3? S4 (S4 is the same as in FIG. 2). In order to perform such knitting, a draw-off knitting protruding portion made up of the needle pins in the same arrangement as the lines 2 and 3 may be added between the lines 3 and 4 shown in Fig. In this case, the increased protruding portion may be reduced by as much as the added drop-off knitting protrusion portion without increasing the line, or the diameter of the presetting drum may be increased to increase the line. In addition, the arrangement of the needle pins is the same as in Fig. 1, and the needle drum is reversely rotated so as to make the second S2 knitting with the needle pins of the second line, The second time S3 may be knitted by the needle pin of the second embodiment.

Further, in forming the draw-off knitted portion of the finger portion, the interval between adjacent stitches in the stitch row may be increased. For example, the draw-off knitting protruding portion may be constituted such that the knitting needle is stapled by two needles. At this time, it is preferable that the unclamped knitting needle is stapled in the second and subsequent draw-off knitting in the first draw-off knitting. For example, all the knitting needles that have not been smoothed are smoothed out in the second draw-off knitting and the first draw-off knitting. Or a part of the knitting needles not to be line-drawn in the first draw-off knitting is stapled at the second draw-off knitting, and the remaining stitches are knitted at the third draw-off knitting.

The throat drum may be configured such that a substantially circular cam plate is inserted into an engaging groove extending in the circumferential direction of the throat drum and the throat is guided by the cam portion of the cam plate projecting from the throat drum See Patent Document 2). In this case, among the cam portions provided in each of the plurality of cam plates, an aggregate of the cam portions parallel to the axial direction of the preferential drum corresponds to each projection portion in the present invention. In addition, the protruding portion may be integrally formed with the throat drum.

The present invention is not limited to the above-described embodiments, but can be appropriately changed without departing from the gist of the present invention. For example, the ratio of increasing the knitting width of each finger may be changed. The knitted fabric to be knitted may be any knitted fabric having a tubular knitted portion having one end closed and the other end opened. For example, a knitted sock having a rounded front portion, Socks with toes, bag-like pockets made of cloth, and the like.
