Abstract

An improved toner rubber mill slab cutter for use in the manufacture of xerographic toner compositions is disclosed. During the course of toner production batch processing, a formulated resin melt is fed to and kneaded between the rolls of a rubber mill forming a continuous sheet output which is placed on a first conveyor belt. A second conveyor belt returns the hot toner sheet to the rubber mill rollers for further milling. After a time, the resultant toner slab is sent to a cooling stage. As the slab exits the mill it is cut widthwise into manageable segments with a reciprocating pizza-cutter like circular knife edge which is slidably mounted beneath an air powered transport cylinder that straddles a mill exit conveyor.
