ABSTRACT:
A composite tape primarily for use in transformer winding as an electric screen and having a backing layer of Melinex plastics tape (112) folded around a metal foil strip of copper (110), and a strip of adhesive PVC tape (114) applied to the folded round edges, is formed by a machine having a braked spool (48) of PVC tape (52) which is fed around a roller (36) with a copper foil strip (58) from a braked second spool (56), sandwiched between the tape (52) and the roller (36), and guide rollers (40, 42) which turn in the outermost edges of the tape (52) to overlie the foil (58), whereafter adhesive tape (66) from a braked third spool is applied to the overlapping edges of the tape (52) by a roller (68) and the composite tape is fed through an outlet roller guide (74).
