Abstract: A hydrostatic drive system has a motor-driven hydraulic pump (1) connected to at least one hydraulic drive unit (7) by a first working line (19) and a second working line (21) forming a hydraulic circuit. The drive unit is connected to a gear set (1, 3). A first hydraulic accumulator (53) for accumulating pressure energy can be connected to one of the working lines (19, 21). A second hydraulic accumulator (55) can be connected to the other working line (19, 21). A valve device (V1, V2) permits the segment (23, 25) of each working line (19 or 21) extending to the drive unit (7) to be separated to separate an accumulator part (33) from the part of the circuit with the hydraulic pump (13). The accumulator part includes the hydraulic accumulators (53, 55) and at least one drive unit.

Abstract: Described is a device for winding ribbon-like material onto spools. Said device comprises at least a first rotating body (10a, 10b) that can rotate around a spool axis (S) and at least a second rotating body (20) that can rotate around the spool axis (S) and can furthermore be moved relative to the spool axis (S) in axial direction from a first end position to a second end position.
