APPARATUS FOR USE IN THE ASSEMBLY OF COMPOSITE FILTER PLUGS

摘要

Filter plugs of double unit length are fed sideways into successive flutes of a rotating drum which moves successive plugs past a rotary knife so that each plug yields two coaxial sections of unit length. Each flute contains two spaced apart mechanical stops at the opposite sides of the cutting plane and each flute has two suction ports which are overlapped by the corresponding stops. The ports draw streams of air which attract the respective sections immediately upon completion of the cutting step so that the sections move away from each other and against the respective stops. Plugs of a different second type are thereupon inserted into the gaps between successive coaxial sections. The cutting station is overlapped by a stationary shroud having an opening through which the knife extends with sufficient clearance to allow streams of atmospheric air to flow into that flute which is located at the cutting station and into the respective suction ports.
