摘要: 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.
