Abstract

In a method for the production of intarsia knitted pieces on a flat-bed knitting machine, at least some of the yarn guides associated with each one of the intarsia areas and the respective needle bed are moved in a direction relative to each other when one of the needle beds is traversed in both lift directions by a carriage provided with one or a plurality of cams in the border area between two areas of intarsia, and the yarn guides are being coupled with the movement of the carriage in each intarsia area. At the end of a movement segment which extends at most across a number of intarsia areas corresponding to the number of cams, the carriage is reversed in its lift direction and returned, together with the yarn guide last used as well as with the yarn guide to be used for the following intarsia area, to the intarsia area last produced, without making a needle selection. In a further movement segment, a further number of intarsia areas corresponding at most to the number of cams is produced in the original lift direction. Becanuse of this a larger number of intarsia areas or colors can be knitted than corresponds to the number of cams in the carriage used without requiring steps w…
