Problems solved by technology

Therefore, the knitting speed can be improved by increasing the speed of the carriage. However, the carriage is a heavy component including a cam system for operating the needles and a needle selection mechanism for determining which needle to operate on the needle bed. There is a limit to speeding up the carriage.

Embodiment

[0047] Figure 1 to Figure 7 The flat knitting machine 2 of the embodiment and the knitting method of the embodiment are shown in . In each figure, 4 and 6 are needle beds, 4 is a rear needle bed, and 6 is a front needle bed. The needle bed 4 can be moved laterally by a motor M2 and a ball screw (not shown), and the needle bed 6 can also be moved laterally by a motor M3 and a ball screw similarly. Assuming that the traverse direction is the longitudinal direction of the needle beds 4 and 6, it is, for example, 1 inch to the right, 1 inch to the left, or 2 inches in total relative to the reference position. The lateral movement of ±1 inch is determined according to the length of the stitches to be moved laterally in one operation, and the needle beds 4, 6 may also be laterally moved in a larger stroke such as ±5 inches. In the embodiment, the needle beds 4 and 6 simultaneously move in the same direction at a constant speed except when the stitches are moved in the longitudina...

Abstract

A knitting fabric is knitted by a weft knitting machine comprising a needle bed, a carriage, and a controller. To perform the knitting, the needle bed is moved in the direction reverse to the moving direction of the carriage while the carriage moves so as to move the needle of the needle bed forward and backward. A knitting speed can be improved by increasing the speed of the carriage relative to the needle.

Description

technical field [0001] The present invention relates to a knitting method on a flat knitting machine, in particular to a knitting method using movement of a carriage and traverse of a needle bed. Background technique [0002] The productivity of a flat knitting machine is proportional to the speed of the carriage relative to the needle bed. This is because the number of needles operated by the carriage is proportional to the speed of the carriage and the number of needles operated by the carriage determines the number of stitches knitted. Therefore, the knitting speed can be improved by increasing the speed of the carriage. However, the carriage is a heavy component including a cam system for operating the needles and a needle selection mechanism for determining which needle to operate on the needle bed. There is a limit to speeding up the carriage. . [0003] Here, if the relevant prior art is presented, Patent Document 1: JP1996-13294A discloses a technology for freely t...
