Abstract

PURPOSE:To provide a method and a device for producing a hosiery having excellent fitness for a foot. CONSTITUTION:The change in a knitting density is transmitted to a knitting density-controlling device through a rod 4 with a knitting density-controlling cam 2 attached to a rotator 1, whereby the main body of the hosiery is knitted in response to a preliminarily set change in the knitting density. The change in the feeding amount of an elastic yarn in transmitted to an elastic yarn-feeding device through a rod 5 with a cam 3 for controlling the feeding amount of the elastic yarn, whereby the elastic yarn is inserted into the main body of the hosiery in response to the preliminarily set change in the feeding amount of elastic yarn. The change in the knitting density and the change in the feeding amount of the elastic yarn are set independently, respectively. When the changes are set to suitable conditions, the same pressures are added to every positions of a foot to give a hosiery having excellent fitness.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing socks with excellent fit to the feet, and an apparatus for manufacturing the socks.

0002

2. Description of the Related Art Conventionally, in order to improve the fit of socks, elastic threads have been inserted into the mouth and body parts of the socks when knitting them. In order to keep the tightening force of the sock on the foot constant, the amount of elastic thread inserted is varied in each part (for example,
9-2051).

[0003] However, the tightening force in each part of the sock differs not only depending on the amount of elastic yarn inserted, but also depending on the tension of each part. That is, the higher the strength, the greater the tightening force, and the lower the strength, the smaller the tightening force. Therefore, the tightening force cannot be adjusted only by the amount of insertion of the elastic thread.

[0004] For this reason, a method has been proposed in which the insertion amount of elastic yarn is varied in accordance with the amount of change in the thread of each part of the sock (Japanese Patent Laid-Open No. 59-94603). In this method, the amount of change in the stitch length adjustment cam is transmitted to the telescopic yarn feeding device via a rod, thereby adjusting the insertion amount of the elastic yarn in response to the change in stitch size.

[0005] However, in this method, since the change in the degree of insertion and the change in the insertion amount of the elastic thread completely correspond,
It was not possible to sufficiently improve the fit of the socks. That is, it is not necessarily the case that it is sufficient to increase the amount of elastic thread inserted at locations where the tension is large, or to reduce the amount of elastic thread inserted at locations where the tension is small.

[0006]

[Problems to be Solved by the Invention] Therefore, the present invention aims to provide socks with excellent fit by presetting the thickness and insertion amount of elastic yarn in each part, and by changing the set thickness and the elastic yarn insertion amount. The idea is to manufacture socks according to changes in the insertion amount of elastic yarn, which is set independently.

[0007]

[Means for Solving the Problems] That is, the present invention knits a sock body with a preset stitch change, inserts an elastic yarn into the sock body with a preset feed rate change, and knits a sock body with a preset stitch change, and inserts an elastic yarn into the sock body with a preset feed rate change. The feed rate change relates to a sock manufacturing method characterized in that it is independently controlled during sock knitting, and to an apparatus for manufacturing this sock.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which a change in the stitch length is transmitted to a stitch adjuster, and a change in the insertion amount of elastic yarn is transmitted to an elastic yarn feeder. Reference numeral 1 denotes a rotating body, which rotates as the sock knitting progresses. A power adjustment cam 2 is attached to one side of the circumferential surface of the rotating body 1. Further, on the other side of the circumferential surface of the rotating body 1, an elastic yarn feed amount adjusting cam 3 is attached. A rod 4 is in contact with the power adjustment cam 2, and is displaced up and down in accordance with the shape of the power adjustment cam 2. Therefore, each displacement amount in the phase of the rotating body 1 is transmitted to a stitch adjustment device (not shown), and the stitches of each part of the sock body to be knitted are determined. Further, a rod 5 is in contact with the elastic yarn feed amount adjustment cam 3, and is displaced up and down in accordance with the shape of the elastic yarn feed amount adjustment cam 3. This displacement is transmitted to the wire 8 via the collar 6 and the lever 7. This wire 8 is connected to an elastic thread guide 9 of the elastic thread feeding device, and the elastic thread guide 9 is moved by displacement of the wire 8. Due to this movement, the passage point of the elastic yarn on the feed wheel 10 of the elastic yarn feeding device is moved. Since the feed wheel 10 is formed of a conical wheel, the amount of feed, that is, the amount of insertion of the elastic yarn in each part of the sock body changes depending on the difference in peripheral speed.

[0009] In this way, socks are manufactured while changing the stitch count and the feeding amount of the elastic yarn, that is, while controlling the amount of change in the stitch count and the insertion amount of the elastic yarn in each part of the sock. . At this time, as is clear from the above explanation, the change in the thread count and the change in the feed amount of the elastic yarn are independently controlled. In addition, changes in the stitch length and changes in the feed amount of the elastic thread are transmitted by the stitch adjustment cam 1 and the elastic thread feed amount adjustment cam 2, respectively. They are designed to fit well and maintain a constant tightening force on the foot. This setting is determined by conducting various experiments while taking into consideration the stitch count, yarn type, etc.

(Manufacturing example) The measurement at the tip of the opening of the sock body is 28 cm, and the measurement is gradually decreased from the tip of the opening until the measurement at a position 10 cm below the tip of the opening is 27 cm.
．． 5cm, and further 10cm from the tip of the mouth.
The shape of the depth adjustment cam was set so that the depth was gradually increased from the bottom position to the ankle, and the height at the ankle was 26 cm. In addition, the feed amount of the elastic thread is 29 cm/circumference at the tip of the mouth section, and the feed amount is gradually decreased from the tip of the mouth section, and the feed amount at a position 10 cm below the tip of the mouth section is 28.5 cm/circumference. Then, reduce the feed amount sequentially from the position 10 cm below the tip of the mouth part to the ankle, and set the shape of the elastic thread feed amount adjustment cam so that the feed amount at the ankle is 27 cm/circumference. did. In addition, as the elastic thread, DCY (urethane 300d x Ef75d x
Ef75d) was used. In addition, cotton yarn 30/1 and FTY20d/70d were used as the yarn forming the sock body. When the socks manufactured under the above conditions were worn, the same degree of tightening force was applied to both the thick and thin parts of the foot, and the socks showed excellent fit.

[0011]

[Operations and Effects of the Invention] As explained above, the method for manufacturing socks according to the present invention involves knitting the sock body at a preset stitch, and knitting the elastic yarn into the sock body at a preset feed rate of the elastic yarn. The change in the degree of insertion and the change in the insertion amount of the elastic thread are determined independently. Therefore, if you set the thread size and insertion amount of elastic thread so that it fits the foot and applies the same level of tightening force to all parts of the foot, you can create socks with an excellent fit. You can get it.
