Abstract: The invention relates to a piston accumulator (1) and a method for determining a position of a piston (5) that can be moved inside a housing (3) of the piston accumulator (1). One or more inductive sensors (15) are arranged on an exterior surface (21) of the housing (3) and configured to detect a movement of the piston (5) inside the housing (3) caused by electromagnetic induction. In this way, a determination of the current position of the piston (5), which is technically simple to realise and contact-free, can be implemented and used, for example, to monitor a charge state of the piston pressure accumulator (1).

Abstract: Winding method for the production of a rotationally symmetric, tube-like hollow body preform, device (10) for the production of a rotationally symmetric, tube-like hollow body preform and a method for the production of a device for producing a rotationally symmetric, tube-like hollow body preform, wherein reinforcing fibres soaked with a resin are wound in a winding process on a rotatably driven winding core (1) having an outside diameter corresponding to the inside diameter of the hollow body preform and wherein the hollow body preform is removed from the winding core after a subsequent hardening of the hollow body preform by means of supplied heat. For the winding process and/or hardening of the hollow body preform, the outside diameter of the winding core corresponds to the inside diameter of the hollow body preform to be produced, wherein the outside diameter of the winding core is reduced to a smaller outside diameter for the removal of the hollow body preform from the winding core.
