A thread clamp for a rapier head () is presented which contains a clamping part () for firmly clamping a weft thread () and an actuator () for moving the clamping part (). The actuator () includes a ferromagnetic core (), an armature () and at least one winding () which is arranged on the core or armature in order to produce a magnetic field in the latter and to move the armature and the clamping part, which is operatively connected to the latter, with the core () having two limbs () between which the armature () is movably arranged, and with each limb being provided with a permanent magnet () in order to hold the armature at one of the two rest positions in the current-free state of the winding.

Thread clamp for a rapier head

The centrifugal pump has a pump rotor unit which is housed within an impeller chamber and which is driven by a permanent magnet coupling having magnetic pole units and pole shoes outside the impeller chamber. The pole shoes define a gap into which an annular part of an end cover of the pump housing projects and into which a magnetizable annular part of the pump rotor unit projects to complete the magnetic flux circuit.
