Description

Plating knitting method with flat knitting machine

In the present invention, two types of knitting yarns are used, and one of the knitting yarns is used as the main yarn, and the knitting yarn and the main yarn are reversed during the normal plating knitting in which the knitting is performed so as to cover the additional yarn of the other knitting yarn. The present invention relates to a plating knitting method in a flat knitting machine that can be switched to a reverse plating knitting.

Knitting needles for knitting the knitted fabric with a flat knitting machine are arranged in the longitudinal direction of the needle bed at a constant pitch. At least two needle beds are used facing each other. The interval between the opposing needle beds is called the tooth mouth. The knitted fabric is knitted with knitting yarn supplied to the hook of the knitting needle from a yarn feeder that runs in the longitudinal direction of the needle bed above the tooth opening. Plating knitting is carried out by feeding two types of knitting yarns, which have different appearances, from two yarn feeders that run over the mouth and are displaced from the preceding and following positions to the hooks of the knitting needles. The knitting yarn is supplied using two yarn feeders having a single yarn feeder and one yarn feeder dedicated to plating knitting having a double yarn feeder. If the knitting conditions such as tension are properly maintained, the knitting yarns supplied from the leading and trailing yarn feeders will be the lower and upper sides at the hook, and the main and main yarns that come out on the surface of the knitted fabric It will be covered yarn. When the traveling order of the two types of knitting yarns is switched, the main yarn and the splicing yarn can be switched to form a pattern on the knitted fabric.

∙ Changing the order of travel of the two yarn feeders is possible even during the course of one course, but it cannot be done instantaneously. Changing the running order while continuing knitting causes the main yarn and the splicing yarn to be switched over a plurality of stitch sections in the knitted fabric, making the pattern boundary unclear. If the knitting is temporarily stopped at the pattern boundary and the knitting is resumed after changing the running order of the yarn feeders, the pattern boundary becomes clear. However, changing the traveling order of the yarn feeder requires a reversing operation of the traveling direction of the carriage on which the cam for driving the knitting needle is mounted, which deteriorates the knitting efficiency.

Even if the traveling order of the two yarn feeders is not changed, if pearl knitting is performed, the splicing yarn and the main yarn can be reversed, but the reversal section becomes the back (for example, paragraph 0002 of Patent Document 1) reference). Patent Document 1 proposes a method of switching between normal plating knitting and reverse plating knitting using a swingable movable sinker (see paragraphs 0016 and 0017 of the specification; however, in Patent Document 1, Corresponding to the plating knitting and the reverse plating knitting are described as standard plating and yarn exchange plating, respectively). In the movable sinker according to this proposal, a convex portion and a concave groove are formed above a portion where a stitch is formed (see FIG. 3 of Patent Document 1). When the main yarn and the splicing yarn are reversed in the reverse plating knitting, the movable sinker is swung so that the main yarn to start drawing is brought into contact with the convex portion by the hook of the knitting needle. The main yarn is raised to the concave groove side to switch the vertical position of the main yarn and the splicing yarn, and the main yarn and the splicing yarn whose vertical positions are switched are pulled in with a hook (see paragraph 0034 of Patent Document 1). In the case of normal plating knitting where the vertical position of the main yarn and splicing yarn is not switched, the knitting needle retracting operation is performed so that the hook does not pull the main yarn and splicing yarn even if the movable sinker swings. Delayed (see paragraphs 0023 and 0024 of Patent Document 1). The switching between the normal plating knitting and the reverse plating knitting is performed by switching the routes by preparing two stitching operations for drawing the knitting needle, and the operation of the movable sinker is the same (FIG. 2 of Patent Document 1). FIG. 11).

JP 2016-176159 A

In Patent Document 1, with respect to the operation of the movable sinker, the knitting needle of the reverse plating knitting is retracted earlier than the knitting needle of the normal plating knitting. Therefore, while forming the stitch of the preceding normal plating knitting near the boundary where the pull of the knitting needle branches from the section of the normal plating knitting to the section of the reverse plating knitting, It will be decided first. The stitches of the normal plating knitting that are determined later are supplied through the stitches of the reverse plating knitting that have already been determined, so that excessive tension is applied to the knitting yarn and the knitting yarn may break. There is. Further, in the section of the reverse plating knitting, the movable sinker swings while the knitting yarn is being pulled in by the hook of the knitting needle (see FIGS. 14 to 17 of Patent Document 1), so that the stability of the stitch and the knitting A negative impact on geological quality is expected. Furthermore, since it is necessary to prepare the stroke of the stitching operation for drawing the knitting needle for two routes, there is a concern about the complexity of the needle selection and the widening of the cam system that drives the knitting needle.

The object of the present invention is that there is no need to change the traveling order of the two yarn feeders, the knitting needle pull-in route is single, and the normal plating knitting and the reverse plating knitting can be switched even during the course of one course. It is to provide a plating knitting method on a knitting machine.

In the present invention, the main yarn and the splicing yarn from the preceding and succeeding yarn feeders are fed to the same knitting needle while maintaining the lower and upper vertical positions, respectively, and knitted so that the main yarn is on the surface side. Play on a flat knitting machine that can be switched between normal plating knitting and reverse plating knitting that reverses the vertical relationship between the main yarn and splicing yarn supplied to the knitting needle so that the splicing is on the front side. In the ting knitting method, a reversing action member capable of switching whether or not the action part at the tip is advanced or retracted upward is provided so as to correspond to the side adjacent to each knitting needle in the knitting progress direction. Every
In reverse plating knitting, the working part of the working member is advanced to the mouth and acts on the main yarn and splicing yarn fed to the knitting needle, so that the vertical position of the main yarn and splicing yarn pulled into the hook of the knitting needle is reversed. And the knitting fabric is knitted so that the splicing yarn is on the surface side.

In the plating knitting of the present invention,
Utilizing a member disposed in the vicinity of the side of the knitting needles to which the knitting needles belong in the direction of the knitting, as a reversal wall that reverses the vertical position in cooperation with the action member;
The action part of the action member is provided at the upper part of the action member, acts from below the main yarn and the splicing yarn, guides the main yarn and the splicing thread to the reversal wall, and cooperates with the reversal wall. The hook is drawn in such a manner that the splicing yarn is on the lower side and the main yarn is on the upper side, and the vertical positions of the main yarn and the splicing yarn are reversed.

In the present invention, the action member and the member are sequentially arranged in the direction of knitting with respect to the knitting needle,
In the reverse plating knitting, the action portion guides and holds the main yarn to the reversal wall in advance of the splicing yarn, and becomes a downward wall with respect to the main yarn and splicing yarn. Together with the upper part of the hook that surrounds so as to become a wall to form a region that encloses and restrains the main yarn and splicing yarn,
It is characterized in that the upper and lower positions are reversed so that the yarn is drawn into the hook from the state where the main yarn and the spliced yarn are lined up surrounded by the region, and the spliced yarn wraps around the lower side of the main yarn.

Further, in the present invention, the reversal wall has an upward slope in which the side of the mouth is low and the side away from the mouth is high,
In the reverse plating knitting, while guiding the main yarn from the action portion to the reversal wall so that the main yarn is on the upper side and the splicing yarn is on the lower side,
The hook is drawn so that the main yarn is on the upper side and the splicing yarn is on the lower side, and the vertical position is reversed.

Further, in the present invention, the action portion of the action member is provided at a lower portion of the action member and acts from above the main yarn and the splicing yarn and pushes the splicing yarn below the main yarn in the reverse plating knitting. It is characterized in that the vertical position is reversed.

Further, in the present invention, the subsequent yarn feeder is characterized in that it travels at a position away from the preceding yarn feeder in the tooth gap interval direction with respect to the needle bed to which the knitting needle belongs.

According to the present invention, the action member provided so as to correspond to each knitting needle can switch whether or not the action part at the tip is advanced and retracted to the mouth. The action member can advance the action part into the tooth mouth during normal plating knitting in which the knitting needle hook is drawn so that the main yarn is on the lower side and the additional yarn is on the upper side. The working part that has advanced advances the vertical position of the main yarn and the splicing yarn drawn into the hook of the knitting needle, so it is possible to switch to the reverse plating knitting where the splicing yarn is on the surface side of the knitted fabric even during the normal plating knitting. Can do. It is not necessary to change the traveling order of the two yarn feeders, and a single knitting needle pull-in route may be used.

Further, according to the present invention, when the action portion of the action member is operated, the main yarn supplied to the lower side and the additional yarn supplied to the upper side are placed on the member arranged near the knitting needle and reversed. Guided to the wall. The action portion can reverse the vertical position of the main yarn and the splicing yarn drawn into the hook in cooperation with the reversal wall.

Further, according to the present invention, the main yarn and the spliced yarn are constrained in a state where they are surrounded by the reversing wall and the action portion and the upper portion of the hook. Since the additional yarn is drawn from the region into the hook so as to wrap around the lower side of the main yarn, the upper and lower positions of the main yarn and the additional yarn drawn into the hook can be reversed from the supply state.

Further, according to the present invention, the reversal wall has an upward slope in which the mouth side is low and the side away from the mouth is high. By guiding to the reversal wall, the main yarn precedes the upper side, and the splicing yarn follows the lower side. Since the main yarn guided by the reversal wall is on the upper side and the additional yarn is on the lower side, the main yarn and the additional yarn drawn into the hook are reversed in the vertical position from the state of yarn supply. be able to.

Further, according to the present invention, the action portion of the action member pushes the additional yarn fed upward on the lower side of the main yarn, and the main yarn and the additional yarn are inverted in the vertical position in the hook of the knitting needle. The yarn can be fed.

Further, according to the present invention, the succeeding yarn feeder travels at a position separated from the preceding yarn feeder in the tooth gap interval direction. Since the front and back difference between the needle beds is added to the main yarn and the splicing yarn, the vertical position of the main yarn and the splicing yarn can be stably reversed by the working portion of the working member, and the action of the working member is stopped. Later, the reversal of the vertical position can be eliminated stably.

It is a top view and a side view shown.

Hereinafter, FIG. 1 illustrates the basic concept of the present invention. 2 to 5 illustrate the first embodiment. 6 to 8 illustrate the second embodiment. 9 to 10 illustrate the third embodiment. For convenience of explanation, portions that are not described in the drawings to be described may be referred to with reference numerals described in other drawings. Corresponding portions are denoted by the same reference numerals, and redundant description may be omitted. Further, the illustration of the old loop is omitted.

FIG. 1 shows a simplified operation of plating knitting on a flat knitting machine as a basic idea of the present invention. (A), (c) shows the operation | movement of the normal plating knitting used as the basis of the plating knitting in a flat knitting machine. In normal plating knitting, for example, when knitting while moving to the left as shown in (a), the main yarn 11 and the splicing yarn 12 are fed from the yarn feeders 1a and 2a of the preceding yarn feeder 1 and the succeeding yarn feeder 2. Feed each yarn. The distinction between the main yarn 11 and the splicing yarn 12 is determined according to the traveling order of the yarn feeders 1a and 2a. Further, not only the two

yarn feeders

1 and 2 having a single yarn feeder, but also one yarn feeder dedicated to plating knitting having a double yarn feeder may be used to supply the knitting yarn. it can. The main yarn 11 and the splicing yarn 12 are fed to the hook 3a of the same knitting needle 3 while maintaining the upper and lower positions of the lower side and the upper side at the mouth 4 as shown in (c). The knitting needle 3 returns to the needle bed while retreating obliquely downward from the tooth center 4a. When the knitted fabric is knitted, the main yarn 11 drawn by the hook 3a so as to be below the splicing yarn 12 appears on the front surface, and the splicing yarn 12 is hidden on the back surface.

Acting members 5 as shown in (b) and (d) are provided so as to correspond to the respective knitting needles 3 in order to enable switching to the reverse plating knitting according to the present invention. As shown in the first embodiment, the second embodiment, and the third embodiment, the action member 5 can switch whether or not the action portion formed at the tip is advanced and retracted above the tooth opening 4. As shown in (d), in the middle of knitting of one course, advancing the action member 5 above the tooth opening 4 acts on the main yarn 11 and the splicing yarn 12 before being fed to the corresponding knitting needle 3. It will be. The action of the action member 5 reverses the vertical positions of the main yarn 11 and the splicing yarn 12 drawn by the hook 3a of the knitting needle 3, and switches the main yarn 11 to the upper side and the splicing yarn 12 to the lower side. When the knitted fabric is knitted, the spliced yarn 12 drawn so as to be lower than the main yarn 11 by the hook 3a appears on the front surface, and the main yarn 11 is hidden on the back surface. Although the main yarn 11 and the splicing yarn 12 may show a cross-section for convenience of explanation as in the portion pulled by the hook 3a, the main yarn 11 and the spliced yarn 12 are not cut in the cross-section and are actually cut to the near side of the page. It is continuous.

According to the present invention, the main yarn 11 and the splicing yarn 12 with which the knitting needle 3 pulls in the course of one course of knitting with the main yarn 11 and the splicing yarn 12 are hooked by reversing the vertical position. It is possible to switch to reverse plating knitting so that the yarn 12 is fed and the splicing yarn 12 is on the surface side of the knitted fabric. Since the knitting efficiency does not decrease even if the switching operation of the main yarn 11 and the splicing yarn 12 increases, knitted fabrics with various patterns can be knitted by the plating knitting. Since the main yarn 11 and the splicing yarn 12 are switched, it is not necessary to change the traveling order of the two yarn feeders 1a and 2a, and the drawing route of the knitting needle 3 may be single.

FIG. 2 and FIG. 3 show in steps the operation of switching the knitting yarn that appears on the surface of the knitted fabric from the main yarn 11 to the splicing yarn 12 in the reverse plating knitting according to the first embodiment of the present invention. Even in the reverse plating knitting, the

yarn feeders

1 and 2 supply the main yarn 11 and the splicing yarn 12 and the advance and retreat of the knitting needle 3 with respect to the tooth opening 4 are performed in the same manner as in the normal plating knitting. The switching operation is performed in the middle of the knitting course, and the main yarn 11 and the splicing yarn 12 are connected to a loop held by the hook 3a of the knitting needle 3 after knitting. The knitting needles 3 are accommodated in the needle grooves of the needle bed 6, and at least a pair of the needle beds 6 are provided so as to face each other with the tooth opening 4 interposed therebetween, but the illustration of the knitting needles on the opposite side is omitted.

The knitting needles 3 are arranged side by side at a constant pitch in a direction perpendicular to the paper surface with the hooks 3a facing the teeth 4. A yarn guide 7 and a movable sinker 8 are provided around the knitting needle 3. A loop presser 15 corresponding to the action member 5 is disposed above the knitting needle 3. The loop presser 15 is accommodated in the auxiliary floor as disclosed in, for example, Japanese Patent No. 4104430. The auxiliary floor is provided above the needle bed facing the needle bed 6 in which the knitting needle 3 is accommodated, but can be provided above the needle bed 6 as disclosed in, for example, Japanese Patent No. 30443373.

The knitting needle 3, the movable sinker 8, and the loop presser 15 operate under the action of a drive control unit mounted on a carriage that runs in a direction perpendicular to the paper surface along the needle bed. In the first embodiment, the action portion 15 a is provided in the upper part near the tip of the loop presser 15, and the loop presser 15 which is a loop presser as an original function also has a function corresponding to the action member 5. A dedicated member functioning as the action member 5 can also be provided. Instead of the movable sinker 8, a fixed sinker may be used as the sinker. 2 and 3, the knitting proceeds in the direction from the front of the figure to the back. In this direction, in the needle bed 6, the yarn guide 7 and the movable sinker 8 are disposed adjacent to the knitting needle 3. Between the yarn guide 7 and the knitting needle 3, the action part 15a of the loop presser 15 can be advanced and retracted from the opposite needle bed side. Therefore, the arrangement toward the knitting progress direction is the order of the knitting needle 3, the action member 5 such as the loop presser 15, the yarn guide 7, the movable sinker 8, and the next knitting needle 3.

As shown in FIG. 2 (a), before the loop is formed by the knitting needle 3, the hook 3a is raised to a clear position and then lowered to a position waiting for yarn feeding. The old loop formed in the hook 3a moves to the needle stem side of the knitting needle 3 by rising to the clear position. When the hook 3a starts to be retracted as shown at

positions

3A, 3B, 3C, the action portion 15a of the loop presser 15 advances below the main yarn 11 and the splicing yarn 12 as shown at positions 15A, 15B, 15C. . The action portion 15a advanced to the position 15C acts from below the main yarn 11 and the splicing yarn 12. On the action portion 15 a, the main yarn 11 is placed side by side at a position closer to the yarn guide 7 than the splicing yarn 12.

As shown in FIG. 2B, when the hook 3a continues to be retracted, the action portion 15a that has advanced to the position 15D causes the main yarn 11 and the splicing yarn 12 placed on the upper portion to move toward the front edge 7a of the yarn guide 7. invite. In the space near the hook 3a of the knitting needle 3 drawn to the position 3D, the leading edge 7a prevents the main yarn 11 and the splicing yarn 12 from moving in the direction of the needle bed 6, and as will be described later, An inversion wall that reverses the vertical position of the splicing yarn 12, the action portion 15 a is a downward wall, and the upper portion of the hook 3 a is an upward wall. The front edge 7a as a wall for preventing the transition is formed by partially covering a wall of the region surrounding the main yarn 11 and the splicing yarn 12 because the angle of the knitting needle 3 with respect to the advancing / retreating direction is close to a vertical range as shown in the figure. It is sufficient that the main yarn 11 and the splicing yarn 12 are prevented from being transferred from the region to the needle bed 6 side.

In this region, the main yarn 11 is fastened to the leading edge 7a, and the splicing yarn 12 is aligned with the main yarn 11 on the side of the tooth opening 4. In addition, when the height of the action part 15a in this area is too high, it becomes difficult to feed the hook 3a, and the vertical drop from the upper edge of the action part 15a into the hook 3a becomes large, and the knitting yarn It will increase the load against. If the height of the action portion 15a is too low, the yarn can be fed, but it is easy to catch the hook 3a with the main yarn 11 on the lower side and the splicing yarn 12 on the upper side. It will be a line of. The height of the action part 15a is determined so as to avoid these problems. The upper part of the hook 3a regulates the splicing yarn 12 so that it does not run on the main yarn 11 fastened to the front edge 7a.

As shown in FIG. 3 (c), the action portion 15a is advanced to a position 15E and intersected with the front edge 7a to be used as a lower wall. When the main yarn 11 and the splicing yarn 12 are caught by the hook 3a from the state of being surrounded by the wall, the splicing yarn 12 wraps around the lower side of the main yarn 11 to reverse the vertical position. The front edge 7a becomes a reversal wall when reversing the vertical position of the main yarn 11 and the splicing yarn 12 by fastening the main yarn 11. The inversion of the main yarn 11 and the splicing yarn 12 is determined by being applied to the outer edge of the movable sinker 8. Until the determination, the loop presser 15 needs to advance at least as a lower wall.

As shown in FIG. 3 (d), when the hook 3a is continuously retracted, the old loop that has moved to the needle stem side of the knitting needle 3 is knocked over. The loop presser 15 needs to be retracted to a position in a range that does not interfere with the old loop to be knocked over, such as the position 15F. The retraction is continued until the needle loop by the hook 3a and the sinker loop by the movable sinker 8 are formed, and the determination is completed. The series of operations for moving the loop presser 15 back and forth is not limited to linear movement as in the first embodiment, but may be up and down by swinging as in the third embodiment.

FIG. 4 shows the knitting operation in the vicinity of the mouth 4 including the switching operation of FIGS. 2 and 3. A drive control unit mounted on a carriage that runs from the bottom to the top of the figure drives the knitting needle 3 and the loop presser 15, respectively. The knitting needle 3 selected for knit is driven so that the tip of the hook 3a draws a locus 3t. In the reverse plating knitting, the loop presser 15 is driven so that the tip draws a locus 15t. If the loop presser 15 is not applied, the normal plating knitting is performed in which the main yarn 11 comes to the surface by waiting at the same position as the flat portion of the locus 15t. In all the embodiments including the first embodiment, switching by the action or non-action of the action member 5 such as the loop presser 15 can be performed at any time for a plurality of continuous knitting needle sections. For example, the course knitting can be ended by switching from the section of the normal plating knitting to the section of the reverse plating knitting, or can be further switched to the section of the normal plating knitting after switching to the reverse plating knitting.

4, 3A, 3B, 3C, 3D, 3E, 3F; 15A, 15B, 15D, 15E, 15F respectively indicate positions corresponding to the operations of the knitting needle 3 and the loop presser 15 shown in FIGS. The loop presser 15 of the first embodiment inverts the main yarn 11 and the splicing yarn 12 upside down in cooperation with the front edge 7a of the yarn guide 7. When the inverted main yarn 11 and the splicing yarn 12 are fed to the hook 3a of the knitting needle 3, as shown in FIGS. 3 (c) and 3 (d), the loop presser 15 has a tooth opening at positions 15E and 15F. Exit from 4.

In the first embodiment, the front edge 7a of the yarn guide 7 is used as a part of the wall of the region where the main yarn 11 is fastened in cooperation with the loop presser 15 and the main yarn 11 and the splicing yarn 12 are restrained. The reversal wall formed by the front edge 7a of the yarn guide 7 can be replaced by another member such as a movable sinker 8, a fixed sinker, or a dedicated member. The member that becomes the reversal wall may be disposed adjacent to the knitting needle 3 in the knitting progress direction so that the action portion 15a of the loop presser 15 advances and retreats between the knitting needle 3 and the reversal wall. . The sequential arrangement of the knitting needle 3, the loop presser 15, the yarn guide 7, and the movable sinker 8 to the next knitting needle 3 shown in FIG. 4 enables stable switching of the plating knitting as the knitting progresses to the left. However, when the knitting proceeds to the right, the reversal wall and the loop presser 15 are sequentially arranged in the knitting progress direction with respect to the knitting needle 3. In this arrangement, there is no downward wall between the reversal wall and the knitting needle 3, and the operation of reversing the vertical positions of the main yarn 11 and the splicing yarn 12 may be unstable. Accordingly, when the knitting proceeds to the right, the position of the loop presser 15 with respect to the knitting needle 3 is shifted by racking, and the knitting needle 3 and the movable sinker 8 are arranged so that the loop presser 15 is adjacent to the knitting needle 3 in the knitting progress direction. To be placed in between. When the knitting is advanced to the right, the knitting needle 3, the loop presser 15, the movable sinker 8, and the yarn guide 7 are arranged in this order. Not only in the first embodiment, but in all the embodiments, when changing the knitting progress direction, the position of the operation member 5 such as the knitting needle 3 and the loop presser 15 is shifted by racking, and the knitting needle 3, the operation member 5, The arrangement of the three members with the inversion wall by the yarn guide 7 or the movable sinker 8 is made equal. The loop presser 15 can be provided not only on the needle bed side facing the needle bed 6 but also on the needle bed 6 side. When the loop presser 15 is provided on the needle beds on both sides, for example, the loop presser 15 on the opposite needle bed side is used in the knitting that proceeds to the left, and the loop presser 15 on the needle bed 6 side is used in the knitting that proceeds to the right. If used properly, racking is not required to equalize the arrangement.

5 and 6 show stepwise the switching operation of the main yarn 11 and the splicing yarn 12 according to the second embodiment of the present invention. In the second embodiment, an action portion 25 a is provided in the upper part near the tip of the loop presser 25 corresponding to the action member 5. The loop presser 25 includes a loop presser 25b similar to the loop presser 15b of the loop presser 15 of FIGS. In the second embodiment, the yarn guide 7, the movable sinker 8, and the loop presser 25 are arranged adjacent to each other in the direction of knitting with respect to the knitting needle 3. That is, the action part 25a of the loop presser 25 advances and retreats on the side facing the yarn guide 7 in the knitting progress direction. However, the arrangement is not limited to this, and the loop presser 25 and the yarn guide 7 are arranged adjacent to each other in the direction of the knitting with respect to the knitting needle 3, and the action portion 25 a advances and retreats between the knitting needle 3 and the yarn guide 7. You may do it.

In the second embodiment, the yarn guide 7 uses an inclined portion 7b formed following the upper end of the front edge 7a as an inversion wall. The inclined portion 7b has an upward inclination such that the side of the tooth opening 4 which is the right side of the drawing is low and the side away from the tooth opening 4 which is the left side of the drawing is high. The upward inclination of the inclined portion 7b guides the main yarn 11 to move on the upper side and the additive yarn 12 on the lower side. It is preferable that the action portion 25a has an upward inclination similar to that of the inclined portion 7b so that the main yarn 11 and the spliced yarn 12 can smoothly transition to the inclined portion 7b. Although the action portion 25a may be flat, it needs to have a shape that intersects at least the inclined portion 7b at an obtuse angle and does not hinder the transition of the main yarn 11 and the splicing yarn 12.

As shown in FIG. 5 (a), the knitting needle 3 is raised to the clear position and then lowered to the position 3A for waiting for yarn feeding before the loop is formed. The loop presser 25 waits at the position 25A.

Other members such as the movable sinker 8, the fixed sinker, or a dedicated member can be used for the reversal wall that cooperates with the action portion 25a.

FIG. 8 shows stepwise the switching operation of the main yarn 11 and the splicing yarn 12 according to the third embodiment of the present invention. In the third embodiment, an action portion 35 a is provided in the lower portion near the tip of the loop presser 35 corresponding to the action member 5. The action part 35a is provided with an inclination that rises toward the tip side. The loop presser 35 includes a loop pressing portion 35b similar to the loop pressing portions 15b and 25b of the

loop pressers

15 and 25 of the other embodiments. In the third embodiment, as in the second embodiment, the yarn guide 7 and the movable sinker 8 are arranged adjacent to each other in the knitting progress direction with respect to the knitting needle 3, and adjacent to the knitting needle 8 from the movable sinker 8 in the knitting progression direction. The action portion 35a of the loop presser 35 advances and retreats on the side to be moved. However, the arrangement is not limited to this, and the loop presser 35, the yarn guide 7, and the movable sinker 8 may be arranged adjacent to each other in the knitting progress direction with respect to the knitting needle 3.

FIG. 8A shows a state in which the vertical positions of the main yarn 11 and the splicing yarn 12 are reversed by the action portion 35a of the loop presser 35 when the hook 3a is captured. Before the loop is formed by the hook 3a of the knitting needle 3, the hook 3a is raised to a clear position and then lowered to a position for waiting for yarn supply. Before the knitting needle 3 is lowered to the position 3C and the drawing of the main yarn 11 and the splicing yarn 12 into the hook 3a is started, the action portion 35a of the loop presser 35 is indicated as indicated by 35A, 35B, 35C. And advance above the splicing yarn 12. The action portion 35a acts so as to be pressed from above the main yarn 11 and the splicing yarn 12. At first, the acting portion 35a acts on the splicing yarn 12 fed at least on the upper side, and pushes the splicing yarn 12 below the main yarn 11 to move up and down. Invert the position.

As shown in FIG. 8B, when the hook 3a is continuously retracted, the splicing yarn 12 pushed downward by the action portion 35a advanced to 35D is also placed on the inclined portion 7b of the yarn guide 7 and becomes the main yarn. 11 is pushed down to the lower side. In the hook 3a of the knitting needle 3 lowered to the position 3D, the additive yarn 12 is captured so as to be lower than the main yarn 11, and the vertical positions of the main yarn 11 and the additive yarn 12 are reversed. Even if the main yarn 11 and the splicing yarn 12 do not rest on the inclined portion 7b of the yarn guide 7, it is sufficient if the main yarn 11 and the splicing yarn 12 are caught by the hook 3a in a state where the vertical position is reversed by pressing the action portion 35a.

FIG. 9 shows the knitting operation in the vicinity of the tooth mouth 4 including the switching operation of FIG. 8 as in FIGS. In the case of the reverse plating knitting, the loop presser 35 is driven so that the tip thereof draws a locus 35t. 3C, 3D and 35A, 35B, 35C, 35D respectively indicate positions corresponding to the operations of the knitting needle 3 and the loop presser 35 shown in FIG. If the loop presser 35 is not applied, the loop presser 35 stays at the same position 35A as the flat portion on the upper side of the trajectory 35t, and the normal plating knitting in which the main yarn 11 comes to the surface is performed.

Even when the loop presser 35 is operated, while waiting at the position 35A, the hook 3a of the knitting needle 3 is once raised to the clear position and then lowered to a position waiting for yarn feeding. When the operation of the loop presser 35 is started and the tooth 4 is advanced to the position 35B, the hook 3a further starts to descend. The loop presser 35 advances into the tooth opening 4 at positions 35C and 35D as the knitting needle 3 is pulled by the angle cam.

FIG. 10 shows a case where the yarn feeder 2a of the splicing yarn 12 and the yarn feeder 1a of the main yarn 11 are moved at positions where the distance from the needle bed 6 to which the knitting needle 3 belongs to the tooth mouth 4 side is substantially the same (a). A comparison is made between (b) and cases (c) and (d) in which the yarn feeder 2a of the splicing yarn 12 travels at a position distant from the needle bed side facing the tooth mouth 4. As shown in (a), the yarn feeders 1a and 2a are generally fed in the vicinity of the center 4a so that the yarn can be fed equally to the knitting needles 3 from the needle beds on both sides. As shown in (b), a plurality of traveling paths are provided above the tooth mouth 4, and the

yarn feeders

1 and 2 traveling on different traveling paths are arranged so that the yarn feeders 1a and 2a are near the tooth center 4a. Inclined.

As shown in (c), the subsequent yarn feeder 2a is opposite to the needle bed 6 to which the knitting needle 3 to which the yarn is fed belongs, on the side of the needle bed opposite to the preceding yarn feeder 1a by the longitudinal difference ΔD at the tooth mouth 4. It is preferable that the vehicle travels at a position distant from each other. As shown in (d), the front-rear difference ΔD is the distance between the center 4a and the center 4b of the yarn feeder 2a of the splicing yarn 12. Since the front / rear difference ΔD is applied to the main yarn 11 and the splicing yarn 12, the reverse plating knitting causes the action portion 35a to act on the state where the main yarn 11 and the splicing yarn 12 are separated by the front / rear difference ΔD. The splicing yarn 12 can be easily pushed in first, and can be stably captured by reversing the vertical position in the hook 3a. Further, the front-rear difference ΔD can be stably returned to the normal plating knitting by stopping the operation of the loop presser 35. The front-rear difference ΔD may be provided by bringing the preceding yarn feeder 1a closer to, for example, the needle bed 6 side than the tooth center 4a. That is, the front-rear difference ΔD may be provided in the interval direction of the mouth opening 4.

Such a longitudinal difference ΔD is preferably provided also in the first and second embodiments. In both of the embodiments, the front-rear difference ΔD is stable and easily arranged in the order without the main yarn 11 and the splicing yarn 12 placed on the action portions 15a and 25a of the

loop pressers

15 and 25 being exchanged.
