16. An apparatus for positioning and gripping tubing in relation to a tube cutting machine comprising:
-
a frame; a pair of juxtaposed inwardly facing guides, adjustably mounted on the frame, each guide comprising a support which is adjustably mounted on the frame and a removable shoe which is carried on the support, each shoe having a concave recess formed therein, the recess having a diameter approximately equal to the outside diameter of the tubing; a pulley rotatably mounted on the frame at each end of the guides; an endless, flexible guide belt surrounding each guide and being mounted on the pulleys; a motor for driving the pulley so that the guide belts are rotated; a controller for controlling the length of tubing fed through the apparatus; and a meter for measuring the length of tubing fed through the apparatus;
wherein tubing inserted into one end of the apparatus is positioned in a cutting head of a tube cutting machine by frictional engagement with the guide belts, the guides are adjustable to accommodate tubing having different outside diameters, and at least two of the pulleys are adjustably mounted to provide variable tension on the guide belts.
