Title:
FLAT KNITTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/021151
Kind Code:
A1
Abstract:
Disclosed is a flat knitting machine that can maintain precise feed lengths of yarn, even when remedial processing is performed while the yarn is being fed in a required yarn feeding mode. A flat knitting machine (31) detects the rotational angle of a main roller (10) in a yarn feeding device (6) by an encoder (32), as shown in (a). If the inclination angle of a buffer arm (7) approaches an upper or lower limit while in the required yarn feeding mode, the mode switches to a fixed arm angle mode as remedial processing. However, a knitting controller (33) performs stitch density correction even during remedial processing. The length of yarn (4) fed from between the main roller (10) and a slave roller (11) toward the buffer arm (7) is calculated based on the difference in the rotational angles detected by the encoder (32). The knitting controller (33) correlates the timing of measurement by the encoder (32) to perform stitch density correction in a fixed buffer arm mode to the inside of the knitting width, as shown in (b).
