Bending and helix-forming apparatus |
摘要 |
The invention relates to a bending or helix-forming apparatus operating by partial but continuous rolling of a long product on a resilient rim portion of a driven rotatable drum, to which portion it is applied by a plurality of rollers having axes parallel to that of the drum, with a pressure sufficient such that its adherence to the said resilient rim portion of the drum ensures that it is positively driven by the latter.
