Abstract
A command device for a dobby machine, which device includes a pattern card having a plurality of perforations bored in a pattern corresponding to a desired fabric and driven in one direction and a feeler needle suspended from a horizontal needle and displaceable longitudinally while being guided by a guide member so as to permit the insertion of a lower end portion thereof into the perforations and the detection of presence or absence of the perforations in the pattern card, whereby to give an operational command to a drive mechanism of the dobby via the horizontal needle so as to cause a heald frame to undergo prescribed up-and-down movement for production of the desired fabric. The feeler needle is elastically flexible in the direction of motion of the pattern card at a portion below the guide member so as to avoid damages to edge portions of the perforations of the pattern card, which damages would otherwise take place due to repeated reciprocation of the feeler needle into and out of the perforations.
