A method of assembling a wheel rotatable about a main axis and having a plurality of peripheral rollers mounted on peripheral axles aligned tangentially about the wheel and radially spaced from the main axis, each peripheral axle joined to adjacent other peripheral axles to form a continuous ring comprising the peripheral axles, the method including the steps of: molding each peripheral axle in a die having a cylindrical cycle for forming the axle shaft of the peripheral axle without longitudinal separation tines, the peripheral axles each having a receiving head portion for receiving a free end of the axle shaft of an adjacent peripheral axle; mounting a roller on each axle shaft; joining the peripheral axles together to form a continuous ring of peripheral axles; and molding a wheel body including a support structure around the continuous ring.
A peripheral axle adapted tangentially about a wheel rotatable about a main axis and radially spaced from the main axis, the wheel having a plurality of peripheral rollers mounted on a plurality of peripheral axles, the peripheral axle comprising:
A peripheral axle forming part of a wheel rotatable about a main axis and having a plurality of peripheral rollers mounted on a corresponding plurality of peripheral axles aligned tangentially about the wheel and radially spaced from the main axis, the peripheral axle being one of the plurality of peripheral axles and comprising:
