A transporting apparatus transports tubing in a forward direction. A tubing cutter is disposed along the transporting apparatus, and is activated at predetermined time intervals to cut a source of tubing into cut tubing portions as the source of tubing is being transported past the tubing cutter along the transporting apparatus. A first sensor is disposed along the transporting apparatus for detecting the leading edge of the cut tubing portion as the cut tubing portion passes by the first sensor on the transporting apparatus. A second sensor detects the leading edge of the cut tubing portion at a subsequent time. A length determiner determines the length of the cut tubing portion, based upon a first amount of time between two activations of the tubing cutter that were used to cut the front and rear portions of the cut tubing portions. The length determiner also measures a second amount of time between detections of the leading edge of the cut tubing portion by the first sensor and by the second sensor. The tubing length is determined using the first and second amounts of time.
