Abstract

1452323 Extruding glass filled polycarbonate M B TUBEX Ltd 29 July 1974 [11 Aug 1973] 38131/73 Heading B5A A rectilinear sided strip, of glass fibre filled polycarbonate material, is made by extruding from a die 7, a concave faced section of the material which is of a thickness 15% greater than that of the strip, and which is sized to correct thickness and shape in passage through the nips of heated sizing rollers 8, from which it is cooled to below 150‹ C. in being drawn by heated take up rollers 11 over a cooling table 9 to a spool 13. Means 10 monitors the sheet thickness on the table 9, and a footage counter 12 is provided. The material is delivered to the extruder hopper 3 as glass fibre-filled granules, being either pre-dried in an oven, or in the hopper, at 115‹ C. for five hours by a hot air current. The extruder barrel is heated in either 4 or 5 zones, with a vacuum assisted vent being provided respectively between the 2nd and 3rd, or the 3rd and 4th zones. An adaptor 6 and the die 7 are also heated. The sizing rollers 8 are chain driven from variable speed rollers, and the upper and lower rollers thereof are pressure adjustable for sizing of the sheet. Heating temperatures are specified for the extruder barrel, adaptor and die, and the sizing and take up rollers. The strip of sheet may be pre-punched for insulation use in switches and relays, e.g. for assembly prior to or during hand or automatic soldering, the material remaining after punching being reprocessed.
