Focus on multifunctional at Witels-Albert
New heavy-duty multifunctional units – the NAR series from Witels-Albert – offer very high transport, straightening and bending forces. These units have been developed for high strength process materials with a diameter or cross-sectional height of between 5.0mm and 25.0mm. With process materials with a lower yield point the maximum allowed diameter or cross-sectional height is increased to 30.0mm.
The term NAR stands for the possibilities to pre-bend, straighten, transport and bend a process material with just one single unit. The minimum 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 a bending roll after a final pair of transport rolls a wire can be bent to a specific curvature radius, for example coiling.
The picture (top right) 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.
Because of the modular design NAR
units offer “maximum performance on a minimum space with an unbeatable cost.”
