Abstract: A filling head for filling an electrochemical cell with electrolyte has a pre-chamber and a filling chamber, as well as a shutoff element which is movable between an open position and a closed position and releases an opening between the pre-chamber and the filling chamber in the open position and closes off the opening in the closed position. The filling chamber has a pressure port. The shutoff element is movable against a restoring force from the closed position into the open position.

Abstract: The invention relates to a device for cutting to length conductor pieces, in particular hairpins, received in a stator core, including a receptacle for the stator core together with the conductor pieces received therein, the free ends of which protrude out of the stator core when in the received state, in particular in the direction of gravity, and a cutting unit which comprises cutting portions that are designed and arranged such that they can be moved toward one another in order to act in a cutting manner from two opposing sides on at least one conductor piece to be cut to length, and the longitudinal axis thereof, during a cutting process.

Abstract: The invention relates to an apparatus and a method for shaping one or more conductor pieces arranged in a stator core, wherein the conductor piece is a hairpin with two elongate legs and a connection portion connecting these two legs, wherein a large number of conductor pieces is arranged in the stator core, which conductor pieces are arranged in rows extending in a radial direction on a plurality of circular paths extending in a circumferential direction, and wherein the shaping takes place in a free end of the conductor piece that projects from the stator core.

Abstract: The invention relates to an apparatus and a method for reshaping one or more conductor pieces arranged in a stator core, wherein a plurality of conductor pieces is arranged in the stator core, the conductor pieces being arranged on a plurality of circular paths running in a circumferential direction in rows which extend in a radial direction, and wherein the reshaping takes place in a free end of the conductor piece projecting out of the stator core.
