Precision cutter for elastomeric cable

A device for cutting an elastomer cable into a precise length segment with a clean surface cut comprising:

• a) a cable advancement system comprising at least two cable feed rollers having a groove which engages the elastomer cable such that a precise length of the elastomer cable is metered out, the groove having a diameter substantially equal to the elastomer cable;
• b) a cable clamping system comprising a pair of clamping dies, capable of clamping the elastomer cable in a fixed position, having a shearing face, wherein each clamping die has a portion cut out thus forming a clamping hole between the pair of clamping dies;
• and
• c) a cable cutting system comprising a first movable razor blade held against the shearing face at a first blade-to-face angle, wherein the first movable razor blade slides along a linear path and shears the elastomer cable as it travels past the clamping hole at a first sawing angle;
• wherein:
• each cable feed roller additionally comprises a shaft;
• and
• the cable advancement system additionally comprises:
• a pair of zero-backlash gears attached to each cable feed roller's shaft, wherein the pair of zero-backlash gears drive the cable feed rollers;
• on at least one cable feed roller shaft, a roller clutch which causes the cable advancement system to feed the elastomer cable in only one direction;
• and
• on another cable feed roller shaft, a feed clutch, having an arm, which advances the at least two cable feed rollers during cable feed and slips during the arm's return motion.
