Description: Multifunctional units, NAR series, offer very high transport, straightening and bending forces. These units have been developed preferably for high strength process materials with a diameter or cross-sectional height of between 5.0 mm and 25.0 mm. With process materials with a lower yield point the maximum allowed diameter or cross-sectional height is increased to 30.0 mm. The NAR designation stands for the possibility to pre-bend, straighten, transport and bend a process material with just one single unit. The number of rolls and the roll alignment varies. Depending on the total number of tasks a NAR unit is equipped with at least five or more rolls. By adjusting bending or respectively straightening rolls in between upstream and downstream; located transport roll pairs, process materials can be transported and straightened simultaneously in a defined manner. In case of aligning and adjusting a bending roll after a final pair of transport rolls a wire can be bent to a specific curvature radius. The picture highlights a NAR unit mounted on a traversing unit. During its defined travel, supported by the traversing unit, the NAR unit transports and bends the wire. If the unit is equipped with an additional pre-bending mechanism and straightening rolls in between the shown roll pairs, four tasks in total could be performed. A pre-bending mechanism always should be part of a NAR unit if the first section of a coil has to be straightened for easy wire threading or handling.
