Fig. 1 depicts the cutting apparatus, while Fig. 2 shows a cross section of
the apparatus taken across 2-2. The cutting apparatus comprises upper block 20. The upper block is fabricated with a central opening. Upper blade 3 is
attached to the upper block. The upper blade has a central opening which
aligns with the central opening in the upper block. The upper blade is a fixed
blade for the cutting mechanism and has a sharp cutting edge 10 positioned all
around the central opening. The cutting edge is inclined at approximately 15
degrees to an axis passing through the center of the cutting assembly. Base
block 1 is positioned in spaced alignment with the upper block of the cutting
mechanism. Base block 1 is fabricated with a central opening which aligns with
the central opening of the upper block.
Lower blade 6 is attached to a slide assembly 4 (Fig. 2). As with the upper
blade, the lower blade has a rectangular outline with a central opening. The
sharp cutting edge 12 is positioned all around the central opening and inclined at
a 15 degree angle to an axis passing through the middle of the cutter assembly.
The cutting edges 10 and 12 are forced together by a spring means (not
shown). Coupling block 7 couples the lower cutting blade to the piston of air
cylinder 18. Cylinder 18 is at...
