A hold-down device for Jacquard controlled loom machines including a resilient element which exerts a spring force on the hook which is attached to the heald of the machine. The hold-down device is arranged between the hook cord and the cord assembly. The spring force provided by the resilient element is determined by the stroke of the Jacquard machine. Where it is desired for the device to be retrofitted to a Jacquard controlled loom machine, a plurality of resilient elements may be arranged in a matrix between two perforated plates, with springs being arranged in guide tubes and a stop member being attached to the cord assembly. The unit formed by the plurality of resilient elements can be arranged at an adjustable height between the frame of the Jacquard machine and the loom.
