Rod and wire roll bending esp for concrete reinforcements

摘要

Adjustable multi purpose roll bending machine for concrete reinforcing wire etc. comprises a pair of lead in and lead-out rolls between which in the plane, in which the workpiece travels, are disposed one or several bending rolls. If two rolls are employed, they may be arranged round a common centre and displaced by turning, pushing and be clamped into various working positions. Pref. two stationary and a number of displaceable rolls fitted to a revolvable disc are provided, the disc being reciprocated whilst the wire is passed over the other rolls helping to dislodge scale and work harden the wire.
