摘要

A diagnostic system for a jacquard machine having a plurality of heald hooks (16) moveable between at least two discrete shed positions, the system including visual sensing means (30) for producing a visual image of hooks (16) located at one of said shed positions during each weaving cycle, and control means (49) for comparing said visual image with a predetermined shed pattern for each corresponding weaving cycle in order to determine whether or not all the appropriate hooks have been selected to define the required shed pattern.
