BONNOT CUTTING TECHNOLOGY

Bonnot offers three core cutter types, each suited to different materials and production requirements. The Rotary Cutter pelletizes extruded material directly at the die face and includes air jets to aid pellet dispersion. The Off-Set Rotary Cutter adapts to pellets or single profiles. The Guillotine Cutter handles large, hard-to-cut materials hydraulically, or smaller profiles with servo-motor precision. All cutter types can be configured with a take-off conveyor and photo eye for automated length control.

Basic Theoretical Factors in Extrusion Augers

If you take a bolt, having a nut on it, and revolve the bolt, in a fixed axis, both the bolt and the nut revolve. Then, if you hold the nut with a wrench, and revolve the bolt, in the proper direction, the nut will travel forward and fall off the end of the bolt. A clay auger works in a similar manner. Inside of the closed auger barrel there is a “clay nut” which moves forward on the screw. The clay nut is ephemeral. The clay nut is constantly being destroyed by passing off the end of the auger, and it is constantly being reformed by feed material entering the closed auger barrel from the feed hopper, or vacuum chamber.
