ABSTRACT:
An electromagnet-striker bar system for the control device of a rotary dobby includes an amagnetic container having an extremely rigid box structure into which the iron cores of the electromagnets are equidistantly inserted and irreversibly locked. Amagnetic spools for supporting the electrical windings are mounted on electromagnetic pole pieces. The container is provided, in that side further from the hinging axis of said striker bars, with a longitudinal groove into which are inserted the amagnetic support and slide shoulders for the free ends of the striker bars. The free ends of the striker bars are hardened by heat treatment.
