Document shredding machine with stripper and cutting mechanism therefore

A shredding machine comprising:

• a. a top housing with a front wall;
• b. a bottom base having a front wall extending upward and rear wall extending upward parallel to and spaced from the front wall, the space between the front wall and the rear wall defining a discharge opening;
• c. a cutting mechanism comprising two parallel cutting cylinders, each cylinder having a plurality of spaced apart cutting disks with the cutting disks of the first cutting cylinder interleaved with the cutting disks of the second cutting cylinder;
• d. a plurality of spaced apart lower strippers integrally formed on and extending from the front wall, a portion of the top of the strippers being arcuately shaped at angle greater than about 120 degrees to partially surround the rear and lower portion of the space between the cutting disks on the first cutting cylinder, the strippers further having a width substantially the same as the width of the space between adjacent cutting disks on the first cutting cylinder;
• and,
• e. a plurality of spaced apart upper strippers integrally formed on and extending from the front wall, a portion of the bottom of the strippers being arcuately shaped at an angle of at least about 120 degrees such that when the top housing is joined to the bottom base the upper strippers substantially abut the lower strippers to substantially surround the space between the disks on the first cutting cylinder.

• g. a plurality of spaced part second lower strippers integrally formed on and extending from the rear wall, a portion of the top of the strippers being arcuately shaped at an angle greater than about 120 degrees to partially surround the rear and lower of the space between the cutting disks on the second cutting cylinder;
• and,
• h. a plurality of spaced apart upper strippers integrally formed on and extending from the top housing front wall, a portion of the bottom of the strippers being arcuately shaped at an angle of at least about 120 degrees such that when the top housing is joined to the bottom base the upper strippers substantially abut the lower strippers to substantially surround the space between the disks on the first cutting cylinder.
