Toothed Disc Rollers and Double-Tooth Systems
topic
Toothed disc units have triangular plucking elements (coarse saw teeth) secured to a shaft with spacers. Teeth are almost always asymmetrical for unidirectional operation. For bidirectional bale openers like the Rieter UNIfloc, symmetrical double teeth are used that are effective in both directions, eliminating the need for direction-of-rotation changes.
Role
Toothed disc design is critical for automatic bale openers that must extract material in both directions of travel. The double-tooth innovation enables single-roller designs that simplify machine construction while maintaining effective material extraction.
