Abstract

1308837 Stretching sheets FARBWERKE HOECHST AG 19 May 1971 [19 May 1970] 15903/71 Heading B5A An apparatus for stretching plastics sheets, e.g. formed from heated P.V.C., polyolefin, or polyester, comprises a pair of rotary discs 4 which contact the edges of the sheet in a manner which excludes air from between the contacting surfaces. The sheet is fed between rollers 2, 3 before the edges are pressed on to the conical or rounded surfaces of the discs. The edges are pressed on to the discs by free running or driven rollers 5 and adhere thereto by atmospheric pressure, due to the absence of any air between the contacting surfaces. The discs 4 can be driven or free running, and their angles or distance apart can be varied, so that the sheet is stretched transversely, and/or longitudinally. The sheet is finally drawn on to take up rolls 6 and 7, which can be arranged to rotate at a greater speed than the rolls 2, 3. The sheet can also be heated by hot gas jets 9 or electric heaters. In Figs. 3 and 4, not shown the sheet is supported between the discs by rollers (10) or a plate (11). Two or more devices can be connected in series.
