Abstract
The invention relates to a brake support (2) holding a hub (3) in a substantially horizontal position, a positioning head (12) and spoke feed and guide members (40,42,44,46). The position of the holes of the hub is detected by a positioning needle (9), lowered under the action of a jack (14) and being inserted into one of the holes to bring it into a predetermined position. The needle is then withdrawn for threading the spokes. The invention applies to methods for automatically threading spokes of spoke wheels.
Claims5
A method for threading spokes into holes provided in flanges of spoke wheel hubs, each flange having corresponding holes, comprising the following steps:
- disposing the hub (3) horizontally and braking its rotation with braking means producing a braking torque greater than the drive torque produced by the weight of spokes when mounted on the hub;
- rotating the hub by drive means (9) to bring a first hole (29) of the hub into a predetermined position (27) for insertion of a first spoke thereinto;
- threading a spoke into each of the corresponding holes of each flange in predetermined directions so that they pass to the side of the other flange, and after introduction, letting them hang under the action of their own weight;
- rotating the hub and bringing the next first free hole into the predetermined position (26);
- continuing with threading spokes and rotating the hub until all the spokes are introduced;
- and
- removing the hub fitted with spokes.
