Abstract
A plastic tube and a method and apparatus for forming it in which a strip of relatively thin plastic sheet material is cut from a roll of the material and wound around a mandrel. Overlapping ends of the strip are sealed to form the tube. The edge of the strip is inwardly bent to form an inwardly extending lip. When used in the manufacture of a capacitor, the tube is placed in a can on top of the disc of insulating material and a capacitor roll is placed in the tube. The edge of the sheet material can be pre-creased so that when folded inwardly, darts of the material form the lip.
