Cutting apparatus

A cutting apparatus comprising:

• a frame;
• a feed belt conveyor installed within said frame and including a plurality of parallel narrow endless belts, said feed belt conveyor having a head section and tail section;
• a first pulley provided at said head section;
• a plurality of lower rotary cutting blades coaxially mounted on said first pulley and having a diameter greater than that of said first pulley, each said lower rotary cutting blade projecting from between adjacent narrow endless belts of said feed belt conveyor;
• a plurality of upper rotary cutting blades provided above said rotary cutting blades, said lower and upper rotary cutting blades defining therebetween an overlap section such that each upper rotary cutting blade partly overlaps a lower rotary cutting blade corresponding thereto;
• and
• a second pulley adapted to be brought into and out of contact with an outer pheriphery of said first pulley beyond said overlap section, said second pulley having a size such that said second pulley does not project from the edge of said lower rotary cutting blades when in contact with said first pulley, said narrow endless belts of said feed belt conveyor being thereby led to proceed from said first pulley while not passing beyond outfeeding edges of said lower and upper rotary cutting blades, said lower and upper rotary cutting blades both being adapted to be removably mounted in said frame.
