The Doffer Brush is used to clean the large drum after you have removed the batt. It looks similar to a "Flicker" but with different points. Use the center portion of the Doffer brush to contact the curve of the large drum. Starting at the seam, swipe the Doffer brush down the drum in the same direction as the teeth on the drum. Continue across the width of the drum. Slowly rotate the drum backwards as you use the brush to clean the entire drum.
The pads are 1.5” wide with 1/2” long points spaced at 72 per inch
It's 3 1/2" wide, almost twice that of the standard one supplied with all Strauch drum carders. Makes removal of the batt, especially from the doublewide drum, much faster.
