    摘要： A FIVE STATION PROGRESSIVE COLD FORMER IS DISCLOSED WHICH IS ARRANGED TO PERMIT RELATIVELY QUICK TOOL CHANGEOVER. THE DIE BREAST, THE BOLSTER PLATE AND THE SHEAR ELEMENTS ARE REMOVABLY CLAMPED IN THE MACHINE BY HYDRAULICALLY-OPERATED CLAMP ACTUATORS. A KNOCKOUT MECHANISM IS PROVIDED WITH A CAM DRIVE WHICH INCLUDES CAM SECTORS THAT CAN BE REMOVED AND REPLACED WITHOUT MATERIAL DISASSEMBLY OF THE CAM DRIVE. AN ADJUSTABLE TUBE NUT IS THREADED INTO THE MACHINE TO ADJUSTABLY DETERMINE THE REARWARD POSITION OF THE KNOCKOUT MECHANISM. POWER MEANS ARE PROVIDED FOR THE ADJUSTMENT OF THE TUBE NUTS. THE SEPARATE FIXTURES ARE PROVIDED TO PERMIT INSTALLATION OF TOOLING AND ROUGH ADJUSTMENT THEREOF ON A DIE BREAST AND BOLSTER ASSEMBLY SEPARATE FROM THE MACHINE. THE MACHINE IS ARRANGED SO THAT A TOOLING CHANGE CAN BE ACCOMPLISHED BEFORE THE MACHINE COOLS TO ENVIRONMENTAL TEMPERATURE SO THAT WARM-UP ADJUSTMENT REQUIREMENTS ARE MINIMIZED.

    摘要： Apparatus and method of reducing in volume waste material comprising comminuting the waste material in a pulverizer and delivering to an extruder-compacter through a precompaction feed chute in which a positive delivery air flow delivers the comminuted material to the extruder-compacter. The air flow is likewise used to recycle air to the pulverizer to assist in positively delivering waste material to the pulverizer. Fluff in the precompaction feed chute is scraped and compacted by a tamper for delivery to the extruder-compacter without impeding the air flow and collection of waste material in the feed chute is eliminated.
