Tricot machine with movable sinkers and movable sinker

Abstract

Provided is a tricot machine having a movable sinker and a movable sinker that can cause a portion acting on a loop, a knitted fabric to be unrestricted even if a moving stroke in a locus of movement relative to a direction of advancement and retreat of a tooth gap is restricted. The movable sinker (1) shown by a solid line is in a state in which an acting region (4) is withdrawn from a tooth gap (11) by pressing of a sinker cam (19) against a passive arm (2a). When the pressing of the sinker cam (19) against the passive arm (2a) is reduced, the acting region (4) of the movable sinker (1) moves to a position shown by a broken line by the urging force of a wire spring (1a). In the course of this movement, the pressing wire (16a) presses a pressure receiving portion (7) of the movable sinker (1), and the acting portion (6), the pressure receiving portion (7), the spring portion (8), and the restricting portion (9) change in a manner such that they become the position and shape shown by the broken line, and thus the locus of the acting portion (6) acting on the loop, the knitted fabric can be unrestricted even if the locus of the moving arm (5) is restricted.

Description

Technical Field

[0001] The present invention relates to a flat knitting machine and a movable sinker having a function of moving back and forth relative to the teeth together with the knitting needles and performing a function associated with knitting the fabric. Background Technology

[0002] Traditionally, knitting on a flat knitting machine involves the hook at the tip of the knitting needle moving back and forth relative to the serration. When knitting yarn is supplied to the hook entering the serration and the hook retracts towards the needle bed, a needle arc is formed using the hook, and a sinker arc is formed using sinkers positioned between the knitting needles. A movable sinker has a portion at its front end below the portion forming the sinker arc that presses the loop downwards towards the serration, allowing this portion to enter the serration and press the loop. When a new loop is formed, the movable sinker causes the portion pressing the loop to float off the loop, stopping the pressing action (see, for example, Patent Document 1). Sometimes, the movable sinker is used in conjunction with a fixed sinker for sinker arc formation (see, for example, Patent Document 2). A movable sinker used with such a fixed sinker has a claw at its front end moving back and forth relative to the serration, enabling it to hook the knitting fabric from one side of the needle bed across the serration and press it down. It is also possible for a movable sinker not used with a fixed sinker to have the function of pressing down on the knitting fabric.

[0003] In movable sinkers like those in Patent Documents 1 and 2, the front end portion, which moves in the direction of advance and retreat relative to the toothed jaws by oscillation, moves along an arc-shaped trajectory corresponding to the radius from the oscillation fulcrum. For oscillating movable sinkers, the oscillation fulcrum is set at a position spaced apart from the toothed jaws. Compared to the distance between the drive unit for oscillation and the oscillation fulcrum, the larger the oscillation radius from the oscillation fulcrum to the front end portion, the greater the travel distance of the front end portion can be. Movable sinkers that move in a linear motion relative to the toothed jaws, rather than by oscillation, are also used. The linearly moving movable sinker is housed in a sinker groove provided in a sinker bed with a flat bottom, and slides within the sinker groove.

[0007] Patent Document 2: Japanese Patent Application Publication No. 2017-89033 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] When a movable sinker enters the toothed opening and presses down on the woven fabric, it is preferable to have a large travel distance in the area where the movable sinker hooks onto the woven fabric and presses down. To increase the travel distance, it is necessary to increase the size of the movable sinker or to set an installation position that allows for a larger travel distance. However, the trajectory of the movable sinker based on its size and installation position is limited to avoid interference with other components. For example, when using a looping presser to press the woven fabric, in a movable sinker that swings in an arc shape, the swing radius of the front end needs to be reduced to avoid interference. When the size and installation position of the movable sinker are limited, the travel distance is limited, which also affects the position of the claws at the front end that press down on the woven fabric.

[0010] The purpose of this invention is to provide a flat knitting machine with a movable sinker and the movable sinker, which can ensure that the size of the travel of the portion acting on the coil and the knitted fabric is not limited even if the trajectory of the movable sinker moving in the direction of the tooth advance and retreat is restricted.

[0011] Methods for solving problems

[0012] This invention relates to a flat knitting machine with a movable sinker. The knitting needles, arranged parallel along the length of the needle bed, move forward and backward relative to the serrations. A fabric is knitted using yarn supplied from above the serrations, causing the knitted fabric to hang downwards from the serrations. The movable sinker has a passive region and an active region. The passive region can withstand a drive associated with the knitting of the fabric, and the active region moves in the forward and backward direction relative to the serrations by driving the passive region. The flat knitting machine is characterized in that the active region of the movable sinker includes at least a moving arm, a pressure-receiving part, an active part, and an elastic plate. The pressure-receiving part can withstand pressure, and the active part can... At least a portion of the action related to weaving of the fabric is performed relative to the advance and retreat of the teeth. The elastic sheet connects the pressure-receiving part and the action part to the moving arm and is elastically deformed by pressing the pressure-receiving part. The flat knitting machine also includes: a support mechanism that supports the moving arm of the movable sinker to be able to move in the direction relative to the advance and retreat of the teeth; a drive mechanism that drives the passive area of ​​the movable sinker to move the moving arm along a first trajectory; and a pressing unit disposed at least in the middle of the first trajectory to press the pressure-receiving part of the movable sinker, causing the action part to transfer from the first trajectory to a second trajectory different from the first trajectory.

[0013] Furthermore, in this invention, the pressing unit is characterized in that it is a wire that passes through the region along the first trajectory of the pressing portion of the movable sinker in the length direction.

[0014] Furthermore, in this invention, the movable settling plate is characterized in that its function is a claw that hooks onto a coil or braid, and the second trajectory passes through a position closer to the toothed side than the first trajectory.

[0015] Furthermore, in this invention, the movable sinker's claw captures the woven fabric hanging down below the teeth on the second trajectory, which is transferred from the first trajectory by the pressing of the pressing unit on the pressed portion, and presses the woven fabric down below the teeth when it returns from the second trajectory to the first trajectory side by releasing the pressing of the pressing unit on the pressed portion.

[0016] Furthermore, in this invention, the movable sinker swings to make the first trajectory arc-shaped, the wire is a toothed wire disposed at the front end of the toothed side of the needle bed, and the claw passes over the toothed wire in an arc-shaped first trajectory.

[0017] In addition, the present invention is characterized by further including a limiting unit, which keeps the active portion of the movable sinker within the range that includes the first trajectory and the range that includes the second trajectory, and restricts it from extending toward the needle bed side facing each other across the teeth.

[0018] Furthermore, the present invention is a movable sinker plate disposed on a flat knitting machine, having a passive region and an active region. The passive region is capable of withstanding a drive associated with the knitting of the fabric, and the active region moves in a direction relative to the advance or retreat of the teeth by driving the passive region. The active region is characterized in that it includes at least a moving arm, a pressure-bearing part, an active part, and an elastic sheet. The pressure-bearing part is capable of withstanding pressure, and the active part is capable of advancing or retreating relative to the teeth of the flat knitting machine to perform at least a portion of an action associated with the knitting of the fabric. The elastic sheet connects the pressure-bearing part and the active part to the moving arm and elastically deforms by pressing the pressure-bearing part.

[0019] Invention Effects

[0020] According to the present invention, even if the movement of the actuating part in the movable sinker of the flat knitting machine, which acts on the coils and the knitted fabric, along a first trajectory in the direction of advance and retreat relative to the teeth is restricted due to interference with other components, the actuating part can still be transferred to a second trajectory different from the first trajectory. This transfer is performed by the pressure-receiving part included in the pressing area of ​​the pressing unit of the flat knitting machine. Therefore, even if the trajectory of the movable sinker moving in the direction of advance and retreat relative to the teeth is restricted, the magnitude of the travel distance of the part acting on the coils and the knitted fabric can be unrestricted.

[0021] Furthermore, according to the present invention, in the region where the pressure portion of the movable sinker passes along the first trajectory, the wire extends along its length. Since the movable sinkers are arranged side-by-side along the length of the needle bed, the structure can be simplified by utilizing the wire as a pressing unit that transfers the actuating portion of each movable sinker to the second trajectory.

[0022] Furthermore, according to the present invention, even if the entry of the claw, which serves as the actuating part in the first trajectory, toward the tooth opening side is restricted, the claw can still enter the tooth opening side via the second trajectory. In the section where it is not necessary for the claw to enter the tooth opening side, interference with other components can be avoided by using the first trajectory.

[0023] Furthermore, according to the present invention, the claw is able to capture the woven fabric on a second trajectory entering the toothed side, and press the captured woven fabric downwards towards the toothed side when returning to the first trajectory.

[0024] Furthermore, according to the present invention, the toothed wire can be used as a pressing unit so that the claws act on the braided yarn or braided fabric on the toothed side by a second trajectory transferred from the arc-shaped first trajectory.

[0025] Furthermore, according to the present invention, even if the coil or braid acting on the tooth side generates tension on the movable sinker's working part toward the needle bed opposite to the working part, the limiting unit can be used to limit it to prevent the working part from extending toward the needle bed side.

[0026] Furthermore, according to the present invention, when the movable sinker is provided on the flat knitting machine, the movable arm, which is at least excluding the working part, the pressure-bearing part, and the elastic sheet, can move along a first trajectory from the working area, and the working part can be transferred to a second trajectory different from the first trajectory. If the working part is transferred to the second trajectory during the part of the travel that requires the working part to act on the coil or the knitted fabric, the travel of the working part can be increased without restriction even if the first trajectory is restricted due to interference with other components or other reasons.

Figures 7 to 12 This describes the structure and operation of the movable sinker 31 and the flat knitting machine 30 equipped with the movable sinker 31, which are embodiments of the present invention. Figures 13 to 17 The figures illustrate the structure and operation of the movable sinker 41, which is an embodiment 3 of the present invention, and the flat knitting machine 40 equipped with the movable sinker 41. Corresponding parts in each figure are indicated by the same reference numerals, and sometimes repeated descriptions are omitted. Furthermore, for ease of explanation, parts not shown in the figures are sometimes referred to by reference numerals shown in other figures.

[0045] [Example 1]

[0046] Figure 1 The shape of the movable sinker 1, as an embodiment 1 of the present invention, is shown. The movable sinker 1 is formed from a metal plate and has a passive region 2, a support region 3, and an action region 4. The passive region 2 includes a passive arm 2a and a wire spring seat 2b, which, when installed on the flat knitting machine 10, bears the drive associated with the weaving of the fabric. The support region 3 is supported by an arc-shaped support portion 3b such that the movable sinker 1, bearing the drive, swings around a pivot point 3a. The action region 4 includes a movable arm 5 and an action portion 6 capable of performing an action associated with the weaving of the fabric through the swinging motion based on the drive of the passive region 2. In this embodiment 1, the movable arm 5... Figure 1The middle part is located to the right of the support area 3, and also includes the part described as the front end part in the background art. The action area 4 also includes a pressure receiving part 7, a spring part 8, and a limiting part 9. The pressure receiving part 7 can withstand pressure. The action part 6 can perform at least a part of the action related to the weaving of the fabric. The spring part 8 connects the action part 6, the pressure receiving part 7, and the limiting part 9 to the movable arm 5, and elastically deforms by pressing against the pressure receiving part 7. The movable arm 5 has a weaving yarn receiving part 5a and a protrusion 5b. The wire spring seat 2b of the movable sinker 1 receives one end of the wire spring 1a. The wire spring 1a and the movable sinker 1 are separate, but can also be formed integrally. Alternatively, the movable sinker can be driven in the direction of entering the toothed opening 11 by means of a triangle, sinker pusher, etc., without the force of the spring. Alternatively, it is also possible to drive in the direction of entering the toothed opening 11 by means of spring force, as in this embodiment 1, and drive in the direction of exiting the toothed opening 11 by means of sinker pusher.

[0047] When the movable sinker 1 is placed on the knitting machine 10 and subjected to pressure from the pressure-receiving part 7, as shown by the dotted line, the spring part 8 elastically deforms, and the actuating part 6 and the pressure-receiving part 7 move. This deformation and movement occur relative to each other within the actuating area 4 by the actuating part 6, the pressure-receiving part 7, and the spring part 8, but not in the moving arm 5. The knitting yarn receiving part 5a and the protrusion 5b of the moving arm 5 correspond to the parts with the same names shown by reference numerals 5B and 5C in Patent Document 2, respectively, but the moving arm 5 of this embodiment 1 has a protrusion 5c. However, although it is preferable to provide the limiting part 9 and the protrusion 5c, they may not be provided. In addition, the shape of the spring part 8 may not be the shape shown in the figure. Furthermore, the spring part 8 can be any spring part that is separate from the movable sinker 1, such as a wire spring or a leaf spring, which elastically deforms when the pressure-receiving part 7 is subjected to pressure.

[0048] Figure 2 Indicates having Figure 1 The structure of the flat knitting machine 10 with movable sinker 1. The flat knitting machine 10 has a pair of needle beds 12 facing each other on the left and right sides of the drawing, separated by a toothed opening 11. Each needle bed 12 has a generally rectangular shape, including a base plate 13 with its long side perpendicular to the paper surface and needle plates 14 arranged at certain intervals along the long direction of the base plate 13. Needle grooves are formed between the needle plates 14 to accommodate knitting needles 15. The knitting needles 15 slide in the needle grooves, causing the hooks 15a at their front ends to move forward and backward relative to the toothed opening 11, forming knitting yarn supplied from above the toothed opening 11. Figure 4 , Figure 5 and Figure 6The loop 20 shown causes the knitted fabric 21 to hang downwards towards the tooth 11. The knitting needle 15 is a latch needle, which opens and closes the hook 15a using the tongue 15b. A retaining sinker 16 is installed at the front end of the needle plate 14 located between the knitting needles 15 on the tooth 11 side. The retaining sinker 16 has an edge on the tooth 11 side for the sinker hook to be hooked when the loop 20 is formed, and also has a through hole for supporting the toothed thread 17 provided at the front end on the tooth 11 side. The toothed thread 17 has the function of easily disengaging the old loop locked to the hook 15a when the hook 15a receiving the yarn withdraws from the tooth 11 to form a new loop 20. The knitting yarn receiving part 5a and the actuating part 6 pass through the upper and lower claws above and below the toothed thread 17 in an arc-shaped trajectory, respectively. When the knitting needle 15 enters the toothed opening 11 to receive the yarn feed to the hook 15a, the knitting yarn receiving part 5a, which becomes the upper claw, presses down the old loop in a way that prevents the old loop removed from the hook 15a from being carried up by the knitting needle 15. For example... Figures 4-6 As shown, the function part 6, which becomes the lower claw, presses down the hanging woven fabric 21.

[0049] Above each needle bed 12, a carriage 18 having triangular faces spaced apart from the surface of the needle bed 12 reciprocates in the longitudinal direction. Along with the knitting triangle that drives the knitting needle 15, a sinker triangle 19 that drives the movable sinker 1 is also provided on the triangular face. Furthermore, the sinker triangle 19 is driven by pressing the passive arm 2a of the movable sinker 1, causing the working area 4 to retract from the toothed opening 11. The drive to bring the working area 4 into the toothed opening 11 is performed by applying force based on the wire spring 1a. The carriage 18 also includes bristles that open the tongue 15b of the knitting needle 15, and loop-forming pressure plates that press the knitted fabric 21 in the toothed opening 11, but these are not shown in the figures. The movable sinker 1 is located on one side between the fixed sinker 16 and the knitting needle 15, and is housed in a state supported by a support 3b on a thin-walled portion provided on the needle plate 14. The arrangement of each part in the front and rear needle beds 12 is substantially symmetrical about the center plane 11a of the toothed opening. However, the movable sinker 1, which is located on one side of the fixed sinker 16, becomes the near front side of the needle plate 14 and the fixed sinker 16 in the front needle bed 12, and the opposite side of the needle plate 14 and the fixed sinker 16 in the rear needle bed 12.

[0050] Figure 3 express Figure 2The structure near the tooth 11 of the flat knitting machine 10. The fixed sinker 16, in addition to the tooth wire 17, also supports a pressing wire 16a, which functions as a pressing unit, and is a wire that runs through the length direction. Furthermore, the fixed sinker 16 is installed in a groove formed on the needle bed 12 in a manner that extends continuously from the front end of the tooth side of the base plate 13 to the bottom, and is fixed by the fixed wire 13a and the bottom wire 13b provided at the bottom of the base plate 13. The movable sinker 1, shown in solid lines, is pressed against the passive arm 2a by the sinker triangle 19, and its working area 4, including the moving arm 5, the actuating part 6, the pressure-receiving part 7, the spring part 8, and the limiting part 9, is withdrawn from the tooth 11. When the pressure of the sinker triangle 19 on the passive arm 2a is reduced, the working area 4 of the movable sinker 1 moves to the position shown in dashed lines by the force applied based on the wire spring 1a. During this movement, the pressing wire 16a presses the pressure-receiving part 7 of the movable sinker 1, causing the actuating part 6, the pressure-receiving part 7, and the spring part 8 to change in position and shape as shown by the dashed line. Therefore, even if the trajectory of the moving arm 5 is restricted, the trajectory of the actuating part 6 can be unrestricted. In the part where the actuating part 6 needs to act on the coil 20 and the braid 21, the movement stroke can be increased. When the sinker triangle 19 does not press the passive arm 2a, the working area 4, including the moving arm 5, the actuating part 6, the pressure-receiving part 7, the spring part 8, and the limiting part 9, is in the position and shape shown by the dashed line.

[0051] Figure 4 The position and state of the movable settling plate 1 are indicated by... Figure 3 The solid line indicates the operation of the flat knitting machine 10. When the knitting needle 15 uses hook 15a to pull the knitting yarn, which has been fed to the needle bed 12 by the tooth 11, to form a loop 20, the movable arm 5 of the movable sinker 1 withdraws from the tooth 11 in a manner where the action of pressing the loop 20 with the knitting yarn receiving part 5a is not performed. When hook 15a is brought into the tooth 11 to receive the supply of knitting yarn to form a new loop 20, the old loop is removed by moving relative to the needle bar side from hook 15a. When hook 15a is pulled in to form a new loop 20, the old loop is unhooked past the tongue 15b of the closing hook 15a and applied to the knitted fabric 21 hanging below the tooth 11. At this position, the pressure part 7 is about to come into contact with the pressing yarn 16a.

[0052] Figure 5 This indicates the next step of the flat knitting machine 10. Figure 4 The action. This action is equivalent to the position and state of the movable settling plate 1 being changed from... Figure 1 and Figure 3 The situation is indicated by the dotted line. The pressure-bearing part 7 receives pressure from the pressing wire 16a, and through the elastic deformation of the spring part 8, the actuating part 6 enters the toothed mouth 11, which can capture the braided fabric 21. Figures 4 to 5In this embodiment, the portion of the working area 4 excluding the working part 6, the pressure-receiving part 7, the spring part 8, and the limiting part 9, namely the moving arm 5, swings along an arc-shaped trajectory that houses the support area 3 within the thin-walled portion of the needle plate 14 and drives it. If the pressure-receiving part 7 is not pressed, the entire working area 4 also swings along an arc-shaped trajectory with a radius equal to the distance of each constituent part from the swing fulcrum 3a. Hereinafter, the totality of these trajectories will be referred to as the first trajectory. In this embodiment 1, the pressure-receiving part 7 is pressed by the pressing thread 16a, which serves as the pressing unit, causing the working part 6, which becomes the lower claw below the toothed thread 17, to move from the first trajectory to a second trajectory different from the first trajectory. This second trajectory is positioned closer to the toothed 11 side than the first trajectory, thus allowing the pressing of the knitted fabric 21 to begin earlier than when continuing the first trajectory. When it is desired to achieve the start of pressing at such a position solely by swinging along the first trajectory, the shape must be designed with a larger distance from the swing fulcrum 3a, requiring a larger space for swinging. In this embodiment 1, the actuating part 6 can be brought close to the toothed opening 11 within a limited space. Therefore, even with a relatively thin knitted fabric 21, the actuating part 6 can reach it by hooking onto the knitted fabric 21. In addition, the second trajectory has a larger swing radius than the first trajectory, so the downward pressing trajectory after hooking onto the knitted fabric 21 can become a near-vertical trajectory. Furthermore, by changing the pressure receiving part 7 and the pressing unit, not only can the position of the second trajectory pass through the toothed opening 11 side, but the second trajectory can also be set to pass above or below the toothed opening 11, positions different from those in the case of the first trajectory.

[0053] Figure 6 This indicates the next step of the flat knitting machine 10. Figure 5 The action involves the pressing of the actuating part 6 against the braid 21 downwards towards the toothed edge 11 and the pressing of the braided yarn receiving part 5a against the coil 20. The position and state of the movable sinker 1 follow the first trajectory. For the actuating part 6, the pressure receiving part 7, the spring part 8, and the limiting part 9, which are transferred to the second trajectory, the elastic deformation of the spring part 8 is eliminated because the pressing of the pressure receiving part 7 is released. The actuating part 6 presses the braid 21 downwards towards the toothed edge 11 when returning from the second trajectory and after returning to the first trajectory. However, the pressing of the braid 21 may only be performed when returning from the second trajectory to the first trajectory. Alternatively, the shape of the pressure receiving part 7 and the arrangement of the pressing wire 16a may be changed to maintain the pressure on the pressure receiving part 7 until the final state without releasing the pressure.

[0054] The coil 20 and braid 21 acting on the toothed edge 11 side sometimes generate tension on the actuating part 6 of the movable sinker 1, such that it moves towards the needle bed 12 opposite to the actuating part 6. In this embodiment 1, a limiting part 9 is provided at intervals on the side away from the toothed edge 11, relative to the pressure-bearing part 7. Figure 6In this process, the pressing thread 16a enters the interval, restricting the movement of the limiting part 9, keeping the actuating part 6 within the range including the first trajectory. The pressing thread 16a and the limiting part 9 function as a limiting unit, which prevents the actuating part 6 from crossing the center surface 11a of the tooth and extending towards the needle bed 12 opposite to the tooth 11, thus preventing detachment. By preventing the actuating part 6 from extending towards the opposite needle bed 12, interference between the movable sinker 1 of the needle bed 12 before and after lateral movement is prevented, as well as plastic deformation of the spring part 8. In the range of action where the actuating part 6 presses down on the braid 21, the limiting part 9 acts as a stop when the actuating part 6 is pulled by the coil 20, including the range where the actuating part 6 presses down on the braid 21. The protrusion 5c of the moving arm 5 also acts as a stop to limit displacement when the actuating part 6 wants to move significantly towards the tooth 11 when the pressing thread 16a presses down on the pressure part 7 rapidly. Furthermore, the protrusion 5c also serves as a stop when the actuating part 6 is pulled toward the opposing needle bed 12. Therefore, the protrusion 5c keeps the actuating part 6 within the range containing the second track. As described above, the limiting part 9, the pressing wire 16a, and the protrusion 5c function as a limiting unit, which keeps the actuating part 6 within the range containing the first track and the range containing the second track, respectively, and prevents the actuating part 6 from extending toward the opposing needle bed 12.

The movable sinker 31 includes a moving arm 35, an actuating part 36, a pressure-receiving part 37, a spring part 38, and a limiting part 39 as an actuating area 34.

The actuating part 36, pressure-bearing part 37, spring part 38, and limiting part 39 move along a first trajectory in the states indicated by solid lines, dashed lines, and double-dot lines, and move back and forth along a second trajectory in the state indicated by the single-dot line. Furthermore, the toothed wire 17 also acts on the limiting part 39. That is, the toothed wire 17 also functions as a pressing unit and a limiting unit. Additionally, the actuating part 36 serves as… Figure 1The function of the woven yarn receiving part 5a of the movable sinker 1.

[0057] Figure 9 , Figure 10 , Figure 11 and Figure 12 Indicates to respectively and Figure 8 The solid lines, dashed lines, single-dot-dash lines, and double-dot-dash lines correspond to the actions of the flat knitting machine 30. Figure 9 In the shown state, the pressure-receiving part 37 is separated from the toothed wire 17 and is not subjected to pressure; therefore, the actuating part 36, the pressure-receiving part 37, the spring part 38, and the limiting part 39 move along the first trajectory. In the following... Figure 10 In the indicated state, the pressure-receiving part 37 contacts the toothed wire 17 and begins to press; the actuating part 36, the pressure-receiving part 37, the spring part 38, and the limiting part 39 begin to move towards the second trajectory. In the following... Figure 11 In the shown state, the extension of the actuating part 36 caused by the pressure of the toothed wire 17 on the pressure-receiving part 37 is at its maximum. Furthermore, Figure 11 It also indicates that when the toothed wire 17 is rapidly pressed against the pressure-bearing part 37, and the actuating part 36 attempts to displace significantly towards the toothed part 11, the limiting part 39 becomes a stopper that restricts the displacement. In the following... Figure 12 In the indicated state, the toothed thread 17 no longer presses against the pressure-receiving part 37, and the actuating part 36, the pressure-receiving part 37, the spring part 38, and the limiting part 39 return to the first trajectory. The toothed thread 17 acts on the limiting part 39 to restrict and prevent the actuating part 36 from disengaging towards the toothed part 11 due to the tension of the braid 21. The actuating part 36 presses the braid 21 in until it is below the toothed part 11. When the hook 15a enters the toothed part 11 in order to receive the supply of braided yarn to form the next loop 20 for the knitting needle 15, in Figures 9-11 The loop 20 fixed to the hook 15a will be removed from the hook 15a and moved relative to the needle bar side to become the old loop 22. The function part 36 of the upper claw can prevent the old loop 22 from being carried upward towards the tooth 11 as the knitting needle 15 enters the tooth 11.

[0059] Figure 13 The shape of the movable settling plate 41, as an embodiment 3 of the present invention, is shown. The movable settling plate 41 includes a moving arm 45, an actuating part 46, a pressure-receiving part 47, a spring part 48, and a limiting part 49 in the operating area 44. The moving arm 45 is relative to... Figure 1 The movable arm 5 has the same structure except that it does not have a portion equivalent to the protrusion 5c.

[0060] Figure 14 Indicates having Figure 13 The structure and operation of the horizontal knitting machine 40 with movable sinker sheet 41. Figure 15 , Figure 16 and Figure 17 This indicates the action of the flat knitting machine 40. This action is related to... Figure 4 , Figure 5 and Figure 6 The operation of the movable sinker 1 shown is basically the same. However, the toothed wire 17 and the limiting part 49 function as a limiting unit, which keeps the actuating part 46 of the movable sinker 41 within the range that includes the first trajectory and the range that includes the second trajectory, and restricts it from extending to the needle bed 12 side opposite to the toothed part 11.

[0061] In this embodiment 3, including embodiments 1 and 2, the flat knitting machines 10, 30, and 40 have a thin-walled portion of the needle plate 14 as a support mechanism for the movable sinker plates 1, 31, and 41. The thin-walled portion is supported by moving arms 5, 35, and 45 of the working areas 4, 34, and 44 of the movable sinker plates 1, 31, and 41, which move along a first trajectory in a direction relative to the toothed edge 11. The moving arms 5, 35, and 45 are portions of the working areas 4, 34, and 44, excluding the working parts 6, 36, and 46, the pressure-bearing parts 7, 37, and 47, the elastic plates (spring parts 8, 38, and 48), and the limiting parts 9, 39, and 49. The flat knitting machines 10, 30, and 40 have a sinker plate triangle 19 as a drive mechanism that drives the passive area 2 to move the moving arms 5, 35, and 45 along the first trajectory. Furthermore, the working parts 6, 36, and 46 also move along the first trajectory until midway. As a pressing unit, it has a pressing wire 16a in Embodiment 1 and Embodiment 3, and a toothed wire 17 in Embodiment 2. The pressing unit is disposed at least in the middle of the first trajectory, pressing the pressing parts 7, 37, and 47 of the movable sinkers 1, 31, and 41, so that the actuating parts 6, 36, and 46 are transferred from the first trajectory to a second trajectory different from the first trajectory.

[0062] The pressing wire 16a and the toothed wire 17, which serve as pressing units, are supported by the fixed sinker 16 in such a way that they pass through the area where the pressing portions 7, 37, and 47 travel along a first trajectory. However, the present invention can also be applied even when only a movable sinker is used without using the fixed sinker 16. A supporting member is provided on the edge of the movable sinker to form a sinker arc, and the wire extending along the length direction is supported. The supporting member may not be provided for each braiding needle 15, or it may be spaced apart between the members. As a pressing unit, even a grooved triangle, a protrusion extending from the fixed sinker in the length direction, etc., can function in the same way as the wire. Furthermore, the movable sinker may not be a swinging movable sinker, but a linearly moving movable sinker. A linearly moving movable sinker can simply be housed in a sinker groove provided in a sinker bed with a flat bottom, and slide within the sinker groove. Such a sinker groove becomes a support mechanism that supports the linearly moving movable sinker. In a linearly moving movable sinker, the portion supported by the sinker groove and sliding therein becomes the support area. A movable arm is supported on the toothed side of the support area, and an elastic plate connects the movable arm to the part corresponding to the actuating part, the pressure-receiving part, and the limiting part. In a linearly moving movable sinker, the movable arm and other parts move linearly along a first trajectory. If the pressure-receiving part is pressed, the actuating part, etc., moves to a second trajectory. If the bottom of the sinker groove is not flat but has a smooth, uneven triangular surface, the movable sinker can also move in a way that incorporates components of other directions in linear motion. Furthermore, as the knitting needle 15, not only can a latch needle that opens and closes via the latch 15b and hook 15a be used, but a composite needle that opens and closes via a slider and hook can also be used.
