What is a zero line?
Its all about alignment of your processing line equipment, including the wire straightener (or tube straightener, cable straightener, flatwire straightener or strip straightener). Making sure that the wire, tube or other material; and all components that touch that material; from beginning to end; are straight, level and parallel. Thats a relaxed description. The formal description follows: back to top Zero line of the processing system means that the material to be straightened runs through the processing system without undergoing any additional bending, deflecting, or guiding. Therefore, It is an advantage for wide spools to be axially adjustable in order to always obtain the required zero line. The zero line of the processing system includes the zero line of the straightener. Zero line of the straightener describes the situation when all the straightening rolls touch the material to be straightened but do not bend it. This setting is usually made with a caliber, hence the term calib
