Abstract
A system, a method and a collapsible and/or folding apparatus may use a wire loop to cut an object. The apparatus may have a wire loop connected to pulleys on a carriage attached to a frame. The carriage may move relative to the frame to direct the wire loop through the object. The apparatus may have arms on the carriage that may be folded and/or a kicker frame pivotably connected to the frame that may be retracted to reduce the overall size of the apparatus.
Claims13
An apparatus for cutting an object, the apparatus comprising:
- a carriage;
- a frame having a first end and a second end located opposite to the first end, wherein the carriage moves on the frame from a first position at the first end of the frame to a second position at the second end of the frame;
- a feed motor for moving the carriage relative to the frame;
- a kicker frame connected to the frame wherein the kicker frame pivots relative to the frame;
- a first arm and a second arm each pivotably connected to the carriage;
- a hinge connecting each of the first arm and the second arm to the carriage;
- a first pulley connected to the first arm;
- a second pulley connected to the second arm;
- a wire attached to the first pulley and the second pulley;
- a drive motor that moves the wire through at least one of the first pulley and the second pulley, wherein the drive motor and the feed motor are hydraulic;
- a first hydraulic circuit that operates the drive motor;
- and
- a second hydraulic circuit that operates the feed motor.
