When Fuller Custom Brush originated the Fullergript® design, a revolutionary brush making process was created.The Fullergript process provides an economical means of incorporating brush technology into a wide range of modern commercial applications. By winding Brush Strip on a mandrel or shaft, a coil brush is produced. Brush density can be varied by your choice of backing size.The amount of fill material increases proportionately with the size of the backing. The lead of the coil (distance between wraps), affects the working surface of the brush and its performances.
Consistent or continuous brush to work surface contact requires a close wound coil (no lead), while an open lead is recommended when working with aggregate, grain or debris.
