Abstract
A supply of continuous thin wall tubing which is drawn by a pair of opposed conveyor belts frictionally engaging the outside surfaces of the tubing first through a tube straightening device before the tube walls become engaged with the aforesaid conveyor belts so that straightened tubing is always subjected to engagement with the surfaces on the conveyor belts. The conveyor belts effect a longitudinal driving movement of the tubing into and through a tube cutting device and thence into a tube length control for accurately positioning the tube relative to the tube cutters in the tube cutting device and before the tube is cut. Once the tube length detection circuitry in the tube length control has been satisfied by the positioning of the tubing, the tube cutters in the tube cutting device is activated to sever the tubing.
