Abstract: A tool for mounting a set of helical rods around an elongated central core includes a pair of cartridges mounted opposite each other around the central core, so that the rods extend along the central core. Each cartridge has a first part comprising a through-hole for receiving one of the rods, and a second part comprising a through-hole for receiving another rod, the second part being movable with respect to the first part from an open position to a closed position. In the closed position, the parts form an annular body extending around a central opening for receiving the central core, the cartridge comprising a surface configured to engage with a driving wheel or a driving belt for transfer of torque to the cartridge. In the open position, a gap is provided between the parts so that the central opening is accessible from a position radially outside of the cartridge.

Abstract: The invention relates to a weightlifting device comprising a longitudinally extending bar, the bar comprising at least one weight bearing section adapted for accommodating one or more free weights comprising an opening adapted for surrounding the weight bearings section. The weight bearing section comprises an end stop for the one or more free weights at a first end of the weight bearing section, a recess at or adjacent to a second opposite end of the weight bearing section and a free weight locking member for locking the free weights and for preventing the free weights from unintentionally falling off from the second end. The free weight locking member is movable in a longitudinal direction of the weight bearing section between the recess and at least one free weight locking position located between the recess and the end stop.

Abstract: The invention relates to a weightlifting device (1) comprising a longitudinally extending bar (10), the bar comprising at least one weight bearing section (30) adapted for accommodating one or more free weights (100) comprising an opening (101) adapted for surrounding the weight bearing section. The weight bearing section comprises an end stop (31) for the one or more free weights at a first end (32) of the weight bearing section, a recess (12) at or adjacent to a second opposite end (11) of the weight bearing section and a free weight locking member (40) for locking the free weights and for preventing the free weights from unintentionally falling off from the second end. The free weight locking member is movable in a longitudinal direction (L) of the weight bearing section between the recess and at least one free weight locking position (33) located between the recess and the end stop.

Abstract: The invention relates to a process for producing a rolling bearing cage, in particular for large rolling bearings, wherein a steel strip with openings for in each case one rolling body is provided and bent to form a ring, wherein, for thermal coating with a thermoplastic powder, the ring is then heated to a temperature above a minimum coating temperature, wherein the ring is then dipped into a fluidized bed comprising the thermoplastic powder, wherein, during the residence time of the ring in the fluidized bed, plastic powder adheres to the ring, melts and forms a continuous coating, and wherein the ring is removed from the fluidized bed after the coating. The invention also relates to an apparatus for carrying out the process.
