Abstract

Abstract: PROBLEM TO BE SOLVED: To change an interval between ribs according to a part of a sock. SOLUTION: In addition to a rubber cam 11 for a knitting needle, which is engaged with a bat of a knitting needle and is raised on a back surface of a carriage 3 so that a rubber thread is hooked on the needle tip, a butt of a jack protruding from a needle bed. And a knitting needle is lifted up by engaging with the rubber needle cam 12 so that a rubber thread is hooked on the needle tip. By appropriately setting an uneven pattern on the outer periphery of the needle selection drum, only the knitting needle having a bat is used. Instead, the rubber thread can be pulled in with other knitting needles.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a flat knitting machine for producing socks with a finger bag.

[0002]

2. Description of the Related Art Conventionally, in a sock 50 with a finger sack as shown in FIG. 5, a plurality of ribs 51 for imparting elasticity are provided in a vertical direction in a portion surrounding a lower leg. The rib 51 is formed by inserting a rubber thread in the circumferential direction between stitches.

[0003] The manufacture of such a sock is performed by a flat knitting machine, like the glove. FIGS. 2 and 3 show the outline of this flat knitting machine.
This will be described with reference to FIG.

This flat knitting machine includes a large number of knitting needles 2 arranged in parallel with a needle bed 1 and a carriage 3 running in the arrangement direction. The carriage 3 has a front carriage 3a and a rear carriage 3b arranged in a hat shape.

[0005] Each knitting needle 2 is engaged with a jack 4, and the jack 4 is provided with a bat 5. Each jack 4 rises and sinks in accordance with the unevenness of the outer periphery of the needle selection drum 7 arranged via the control jack 6, and a bat 5 projecting from the needle bed 1 with the floating of the jack 4 forms a knitting cam 8 on the back surface of the carriage 3. The knitting needle 2 to be driven by engaging with the knitting needle is selected, and the knitting operation is performed by the knitting needle 2. In the illustrated flat knitting machine, the protrusion of the needle selection drum 7 is formed by a needle selection pin 9 inserted into an axial groove.

[0006] A bat 10 is provided for each of the knitting needles 2 arranged in parallel at a predetermined interval.
Engages with the knitting needle rubber mountain cam 11 on the rear surface of the carriage 3 to raise the knitting needle 2, and inserts the rubber thread hooked on the needle tip 2a between the stitches at the time of lifting to form a rib. Here, FIG.
, The passage of the knitting needle 2 through the bat 10 is indicated by a solid line, and the passage of the jack 4 through the bat 5 is indicated by an alternate long and short dash line.

[0007]

However, as described above, in the flat knitting machine in which only the knitting needle 2 having the bat 10 is engaged with the rubber cam 11 for the knitting needle and rises to draw the rubber thread, the portion of the sock is There is a problem that the rib interval cannot be changed according to the condition.

Accordingly, an object of the present invention is to provide a flat knitting machine capable of changing the interval between ribs in order to impart optimal elasticity to each part of a sock.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a jack having a number of knitting needles arranged in parallel with a needle bed and a carriage running in the direction in which the knitting needles are arranged. Each jack is moved up and down in accordance with the unevenness of the outer periphery of the needle selection drum arranged via the control jack, and the bat protruding from the needle bed with the floating of the jack is engaged with the knitting cam on the rear surface of the carriage. The knitting needle to be driven is selected, and the knitting operation is performed by the knitting needle, and among the parallel knitting needles,
A bat is provided for each one separated by a predetermined interval, and the bat engages with a knitting needle rubber mountain cam on the back surface of the carriage to raise the knitting needle, and inserts a rubber thread hooked on the needle tip between the stitches at the time of raising. In a flat knitting machine in which ribs are formed, a jack rubber is formed on a rear surface of the carriage so as to engage a butt of a jack protruding from a needle bed to raise a knitting needle so that a rubber thread is hooked on the needle tip. A mountain cam was provided.

With this configuration, the rubber thread can be drawn not only by the knitting needle having the bat but also by other knitting needles by appropriately setting the uneven pattern on the outer periphery of the needle selection drum. The rib spacing can be changed.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The same parts as those of the conventional flat knitting machine described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in the drawing, the back of the carriage 3 of the flat knitting machine according to the present invention has a needle bed 1 in addition to the cams described above.
A jack rubber mountain cam 12 is provided to engage the butt 5 of the jack 4 protruding from the needle 4 to raise the knitting needle 2 so that a rubber thread is hooked on the needle tip 2a. In FIG. 1, the passage of the knitting needle 2 through the bat 10 is indicated by a solid line, and the passage of the jack 4 through the bat 5 is indicated by an alternate long and short dash line.

With this configuration, the bat 10 can be set by appropriately setting the uneven pattern on the outer periphery of the needle selection drum 7.
Since the rubber thread can be drawn not only with the knitting needle 2 having the following but also with other knitting needles 2, for example, the sock 53 shown in FIG.
As described above, ribs 54 and 55 having different intervals depending on the portions can be formed.

[0014]

As described above, in the flat knitting machine according to the present invention, the rubber thread is drawn not only by the knitting needle having the bat but also by other knitting needles by appropriately setting the uneven pattern on the outer periphery of the needle selection drum. Therefore, the interval between the ribs can be changed according to the part of the sock, and the optimal elasticity can be given to each part of the sock.

Claims (1)

(57) [Claims] 1. A plurality of knitting needles 2 arranged in parallel on a needle bed 1 and a carriage 3 running in the direction of arrangement thereof. A jack 4 having a bat 5 is engaged with each knitting needle 2, and each jack 4 is controlled. The bat 5 protrudes from the needle bed 1 as the jack 4 floats and engages with the knitting cam 8 on the back surface of the carriage 3 in accordance with the unevenness of the outer periphery of the needle selection drum 7 arranged via the jack 6. The knitting needle 2 to be driven is selected, the knitting operation is performed by the knitting needle 2, and a bat 10 is provided for each of the parallel knitting needles 2 separated by a predetermined distance. The knitting needle 2 is raised by engaging with the rubber mountain cam 11 for knitting needles, and a rubber thread hooked on the needle tip 2a is inserted between the stitches when the knitting needle 2 is raised to form a rib. 3 is provided with a jack rubber mountain cam 12 for engaging the butt 5 of the jack 4 protruding from the needle bed 1 to raise the knitting needle 2 so that a rubber thread is hooked on the needle tip 2a.
