COOLING* TRANSVERSE DIMENSIONN DETERMINING* AND WARPPREFORMING APPARATUS FOR BELT OF SYNTHTIC RESIN SHEET |
摘要 |
An apparatus for the cooling, straightening and calibration of a plate-shaped synthetic-resin strand, e.g. of thermoplastic material extruded from a broad-slot nozzle comprises a plurality of straightening rollers on respective stands, the rollers of each stand engaging opposite surfaces of the strand. The rollers are provided with cooling and heating means to ensure homogeneous temperature distribution throughout the strand passing between the pairs of rollers which can be aligned with one another or can be offset from one another. On at least one of the stands the rollers are displaceable alternately parallel to the path of the strand by corresponding oscillating drive. |
