Abstract:
Apparatus for influencing movement of at least one thread comprising a linear motor including a stator for producing a magnetic field, an armature arranged in the magnetic field, first and second flexible mounting parts for mounting the armature and arranged parallel to one another in such a manner that the armature is movable relative to the stator, the mounting parts having elongated leaf springs each including a first end connected to the stator and a second end connected to the armature, the stator having first and second plates made of ferromagnetic material which are spaced apart and arranged parallel to each other, the armature being arranged between the first and second plates and the first and second plates being spaced with respect to the armature, the armature having a coil body with a core, side walls and a coil, at least one of the core and the side walls consisting of non-ferromagnetic material, wherein the leaf springs extend in the direction of the first and second plates, and the armature is arranged so as to be mounted without clearance and movable in the direction of the first and second plates, and at least one first member connected to the armature so that the first member can act on the thread to thereby influence the movement of the at least one thread.
