Helix straightener

A wire wound into a coil or onto a spool should have only one curvature - that of the spool or coil - in one plane if the follow-up process is to proceed without difficulty. Changing preliminary processes with sometimes inconstant process transitions create helicities, i.e. twisting, in the wire.

Helicities need to be avoided or, where constant helicities are concerned, eliminated by means of a helix straightener. A helix straightener can produce as well as remove helicities.

Like a standard straightener, a helix straightener has several straightening rolls which are partly or fully arranged in familiar manner so that they can be adjusted relative to each other.

In addition to this, one or more straightening rolls can be adjusted in height. The groove of the height-adjusted straightening roll thus forces the wire unilaterally from its zero line, bending it with unequal flank pressure into a second curvature plane. Helicities are thus removed or created by force-feeding the wire through these adjustable positions.
