Aluminum and PVC cutting Machine Table Brushes
A metal channel strip brush is an instrument consisting of natural or synthetic bristles held securely in place by a U-shaped metal channel and center wire. The metal channel is first formed from flat steel (see chart below) into the “U”. The filaments are also folded into a U shape with the center wire lying in the bottom of the formed filaments. The filaments and center wire are inserted into the metal channel just before the metal channel is squeezed tightly, securing the filaments into the brush.
