Description

  The present invention relates to a circular knitting machine, and is a kind of plush knitting machine capable of producing a particularly long hair.

A knitting machine for producing a plush fabric is also called a faux fur knitting machine. The technology of manufacturing a plush fabric using a circular knitting machine has been well known. For example, Patent Document 1, which has already been published as an approval, discloses a flat needle mainly installed on a cylinder and a needle bed horizontally. Using a mutual operation of a plurality of installed sinkers (Sinker), the plush yarn is hung on the front end of the sinker to form a long loop.
In addition, US Patent Document 2, Patent Document 3, and Patent Document 4 that have already been granted, which have been publicized separately, are basically all arranged in a non-bella cylinder needle and needle dial installed on the cylinder. It is a plush fabric made by utilizing the three-way interoperation of the Bella needle and the cutting unit. Among them, the loop is formed by the hook needle of the cylinder needle without a spatula, the loop hooked on the hook needle of the cylinder needle, the cloth presser sinker that slides on both sides of the cylinder needle, and the sinker with the blade at the front end. Use, loop cut to make plush.

  In the two already known Patent Documents 2 and 4, the hair length is determined by the distance from the hook needle of the cylinder needle to the needle bed fringe portion. Generally, the plush length of the plush fabric produced and completed by these techniques is approximately 3 mm, and when this type of bristle foot fabric is used as a faux fur or fur fabric for a stuffed toy, With just 3mm long hair, it is difficult to achieve a true effect. In order to increase the hair length, it is necessary to increase the distance from the hook needle of the cylinder needle to the needle bed fringe portion. In order to achieve this by increasing the diameter of the cylinder, it is necessary to increase the diameter of the sinker ring on which the blade is placed so as to surround the outer periphery of the cylinder. However, if the diameter of the sinker ring is increased, the relative position and dimensions of the blade and cylinder needle on the upper surface will also be changed. And cannot be made into a plush.

  The main object of the present invention is to provide a knitting machine used for producing a plush fabric, in particular a plush knitting machine having a hair length of 12 mm.

  Among the comparatively good embodiments according to the present invention, a knitting machine used for manufacturing a plush fabric is a cylinder needle without a spatula disposed on a cylinder, a spatula needle horizontally disposed on a needle dial, And one cutting unit. Among them, the distance between the needle bed fringe and the cylinder needle is increased by changing the size of the needle bed. In addition, the plush thread forms a loop in the hook needle part of the cylinder needle without a spatula, then pulls the plush thread in a loop with the flat needle placed on the needle bed, forms a long loop, and finally cutting Loop cut with the unit to form a plush fabric with long fur feet.

The invention of claim 1 is a knitting machine used for manufacturing a plush fabric, which includes a non-bella cylinder needle arranged in a cylinder, a bella needle arranged in a needle dial, and a cutting unit. The plush thread is hung on the hook needle part of the cylinder needle without the spatula, and then the plush thread is pulled by the bella needle placed on the needle bed, forming a long loop, and finally cutting Cut the loop with the unit to form a kind of plush fabric with long hairs,
The feature is to manufacture plush fabric, characterized in that the distance between the fringe of the needle bed and the hook needle of the cylinder needle is 10-15 mm and the plush yarn is formed into a long loop. The knitting machine is used.
According to a second aspect of the present invention, in the knitting machine used for manufacturing the plush fabric according to the first aspect, the length of the plush fabric made by cutting the loop is 12 mm. ) Is used for manufacturing.

  The present invention is to provide a knitting machine used for producing a plush fabric, in particular a plush knitting machine having a hair length of 12 mm.

First, FIG. 1 shows a knitting unit of a circular knitting machine for producing a plush fabric. That is, in the part of converting the yarn into a woven fabric, a relatively good embodiment according to the present invention includes the following.
A cylinder needle 11 without a spatula arranged in a cylinder 10, a latch needle 21 arranged in a needle dial 20, and a cutting unit 30. The cutting unit 30 includes a pair of sinkers 31, 32 (see FIG. 2) and a cam 33. The sinkers 31, 32 are linked to the cam 33 and simultaneously slide on both sides of the cylinder needle 11. . Among them, one sinker 31 has a blade 310, and when the cylinder needle 11 slides, the blade 310 cuts the loop 41 formed by the plush thread 40 to make a long bristle foot (see FIG. 3).

  In a relatively good embodiment according to the present invention, the distance D between the needle bed fringe 22 and the hook needle 112 of the cylinder needle 11 is increased to 10 to 15 mm by changing the size of the needle bed 20 to increase the hook needle 112. Pulling the plush thread 40 on the part with the Bella needle 21 to form a long loop 41, and finally cutting the loop 41 with the cutting unit 30 to form a kind of plush fabric that reaches approximately 12mm in length To do.

  The manufacturing process of the splash is as shown in FIGS. First, a plush thread 40 is inserted between the front end 110 of the cylinder needle and the hook 210 of the Bella needle, and a ground thread 50 is connected to the rear end 111 of the cylinder needle and the needle bed. It is inserted between the fringes 22 (see FIG. 4). When the Bella needle 21 moves toward the left in FIG. 5 and retracts the needle, the cylinder needle 11 starts to rise at the same time, and the hook needle 112 rises to a height at which the plush yarn 40 is knitted. The plush thread 40 is pulled by the hook 210 of the Bella needle and is hooked on the hook needle 112 of the cylinder needle 11 to form a loop 41. The Bella needle 21 continues to pull the needle, and when the ground thread 50 is hooked on the needle and moves to the hypotenuse 23, it is guided to the hypotenuse 23 and gradually approaches the lower side of the hook 210. Subsequently, the ground yarn 50 moves to below the plush yarn 40 (see FIG. 6), and then the cylinder needle 11 rises and tightens the loop 41 using the hook needle 112. Due to the interaction between the cylinder needle 11 and the Bella needle 21, the loop 41 formed by the plush thread 40 is directly knitted into the knitted fabric structure constituted by the ground thread 50, and finally using the blade 310, Cut the loop 41 (see FIG. 7) to form a plush fabric with long bristle feet.

2 represents the structure of a relatively good embodiment of the present invention. 2 represents the structure of a relatively good embodiment of the cutting unit of the present invention. The cutting unit cuts the loop and displays the shape that forms the plush. Fig. 3 shows a flow of operations for producing a plush fabric, based on the structure of a relatively preferred embodiment of the present invention.
