  • Patent number: 4652409
    Abstract: A process for producing a stretched web of plastics material wherein a web of plastics material is passed through an apparatus in which the web, gripped at its edges by web gripping devices mounted on carriages which run on guide rails is stretched by increasing the distance between adjacent gripping devices by altering the degree of extension of an articulated chain to which the carriages are attached.

  • Patent number: 4191719
    Abstract: A method for the production of a stretched multi-cellular polyolefin article. A composition comprising a blend of a crystalline polyolefin and about 2-50% by weight of a metal resinate is formed into a shaped article. The shaped article is either uniaxially or biaxially stretched at a temperature between the glass transition temperature and the crystalline melting point of the polyolefin resin to form a multi-cellular article.

  • Patent number: 3974248
    Abstract: A system for determining and/or controlling the profile of a property of an article, in which sensing means simultaneously obtains a multiplicity of electrical gauging signals, each signal being proportional to a property of the article in a particular region, the gauging signals are passed to electrical circuit means which detect any difference in magnitude between the signals from a given region and the average for all such signals and deriving a functional signal for any such difference.
