ABSTRACT:
A plastic tube is sealed at its end by placing the tube in a pair of spaced apart tube holders having tube receiving pockets. The tube is cut by a cutting device movable into and out of the space between the pockets to form two distinct tube sections which are melted at their ends while in the clamped condition. The cut ends are then brought into contact with each other in a mis-aligned condition offset by one-half the thickness of a tube wall to seal the tube end.
