Stack molding apparatus

摘要

Pressed articles such as brake linings are made by a stack molding apparatus and method. Measured charges of moldable material are sequentially placed on top of a vertical stack between spacer plates and compressed. When a predetermined number of charges have been made and compressed in the stack, a fully compressed article has formed at the bottom of the stack. The lowermost fully compressed charge is then removed while alternately a new charge of moldable material and spacer plate are added to the top of the stack in a continuous sequence.
