Abstract
An electromagnetically activated jacquard control arrangement comprising a plurality of control elements each combined with a lifter element (16) and each provided with an electromagnet (19) with an armature (21). There is further provided a lifter plate (7) which, in each working cycle, lifts the lifter element (16) out of a rest position into a working position and which thereafter is again lowered so that the lifter element, in dependence upon the activation condition of the electromagnet, remains in the working position or returns to the rest position. Every lifter element (16) comprises a hook (26) which operates together with a counterhook held in a predetermined elevation. Each armature (21) is rotatably mounted on an axis (24) and by its swinging movement, displaces the counterhook into or out of the path of the lifter element hook. The lifter plate (7) can lift the lifter element beyond the working position into a predetermined zone. Further lifter plate (7) carries a dog plate (29) which swings the armature against the appropriate electromagnets (19) when the lifter element is located in the aforesaid predetermined zone. This mode of construction requires relatively littl…
