<p>A cable stranding machine has an elongate rotor (1) comprising at least one pair of longitudinal beams (9,10) and pairs of bobbin bearing devices (16,17) mounted on the beams in spaced relationship along the rotor length. The bearing devices have pintles (19) supporting thread bobbins (29) for rotation about parallel horizontal axes perpendicular to the rotor axis. Each pintle (19) is rotatable relative to a pintle support (18,27) which in turn is secured to the respective rotor beam (10,9). One or preferably both pintle supports in each pair of bearing devices are formed with means (32-34) permitting them to be secured to the respective beam in a finite number of different axial positions, whereby the rotor can readily be adjusted to receive bobbins of correspondingly different nominal width. Additionally, at least one pintle (19) in each pair of opposed bobbin bearing devices is axially displaceable relative to its pintle support (27) between an advanced position in which a bobbin is held securely between the opposed pintles for rotation therewith, and a retracted position utilized for loading and unloading the rotor.</p> |
