Splicing Motion Picture Safety Film without Cements or Adhesives

A method and apparatus for butt-weld splicing motion picture film, not requiring the usual scraping or cements, are described. The principle is based on a combination of a controlled heat and cooling gradient applied under pressure within a given time cycle, and producing a homogeneous splice. Properties of the film are not affected, as the film is automatically preplasticized prior to splicing. The method may be used for all types of safety film.
