Flatbed knitting machine including control data conveying means

摘要

In a flatbed knitting machine having one or more carriages movable reciprocally or, on a closed path with respect to one or two needle beds, control data is conveyed to the or each carriage by light or other electromagnetic radiation or acoustically, one or more data transmitters being located externally of the needle bed or beds and the carriage having means for processing and storing data relating to at least one knitting course. The transmission zone is screened or otherwise shielded against interference. The transmitted signals may be modulated in various ways and alarm and timing control arrangements are described.
