ABSTRACT:
In order to prevent cutting of inner windings of a film (39) wound on a pair of arbor halves (34 and 38) during sequential withdrawal of the arbor halves following a winding operation, the arbor halves are forge formed with rounded protuberant winding surfaces (51, 52 and 53). The rounded surfaces may be coated with a low friction plastic to enhance sequential arbor withdrawal without pulling the inner convolutions from the wound film plastic (39). Further, the arbor halves are provided with ends (36) bent beyond 90.degree. so that the arbor halves may force seat in holes (42) formed in holders. The arbor bent end construction will also allow an operator to strike the bent end of the arbor half in a hole to quickly remove a defective arbor to permit quick replacement with a new arbor half.
