ABSTRACT:
The Jacquard machine employs a selector system for blocking and un-blocking the pressers (e.g. Jacquard needles) wherein use is made of a control means comprised of two electrically magnetizable relatively movable rods. Upon energization of a magnetic field generator, the rods move away from each other so that one of the rods is moved into a blocking position relative to a presser needle. Upon de-energization of the magnetic field generator, the rods come together so that the presser needle is unblocked.
