Abstract: A system for cutting medical tubing sourced from a spool of tubing uses two actuator groups that each reciprocate along a respective track, which are parallel to each other. Each actuator group has a clamp and a cutting tool which have an operative position along a common axis. The tubing is fed along the common axis to be operated on by the actuator groups. A forward actuator group clamps onto the tubing and is then moved along its track, pulling the tubing. A rearward actuator group then clamps onto the tubing and cuts the tubing. While still clamped onto the tubing, the rearward actuator group is moved forward, pulling more tubing, and the actuator group that was forward is moved to the rearward position and the process is repeated iteratively to produce tubing sections cut to the desired length. The tubing is pressurized and kept under pressure to straighten the tubing.
