Innovation in the plate brush production for road sweeping use

GB 20 angle drilling and milling unit

The GB 20 from Wöhler Brush Tech is the leading system for fully automatic production of street-sweeping-plate brushes which are in use worldwide. Nevertheless, Wöhler is busy in further development the machines for greater efficiency and innovative, new products.

The servo driven angle drilling and milling unit of the GB 20 allow the making of fill holes for plastic and wire fill in adjustable angles and/or milled pockets.

The advantage over conventional straight holes (no angle) is a considerably higher fill material stability, resulting in enhanced cleaning action and performance.

1. In the case of straight drilled holes the distance and angle of the contact points remain the same. The angle of the fill material cannot be varied. (Abb. 1)


2. By varying the angle on drilling the contact points can be shifted accordingly. The angle of the fill material can be arbitrarily varied, producing higher stability. (Abb. 2)


3. For increasing the sweep effect the angle of the block can also be varied on drilling. (Abb. 3)
