Abstract

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.

Claims9

Dependent claims

In an apparatus for manipulating rod-shaped articles, particularly in an apparatus for assembling composite filter plugs, the combination of a conveyor having a plurality of article receiving means and a pair of spaced apart stops for each receiving means;

means for advancing said receiving means sideways along an endless path;
means for feeding rod-shaped articles into said receiving means between the respective stops in a first portion of said path;
means for severing successive articles in a second portion of said path so that each severed article yields two coaxial rod-shaped sections;
and means for moving the sections of successive severed articles apart and into abutment with the respective stops immediately upon completed severing of the respective articles, including means for establishing a pressure differential between the ends of sections with the lower-pressure zone located at that end of each section which faces the respective stop so as to induce axial movement of said sections against the respective stops, said pressure differential establishing means comprising a shroud overlying the receiving means in said second portion of said path and suction ports provided in said receiving means in the region of said stops.
