PROCESS AND APPARATUS FOR THE PRODUCTION OF A PACKING SHEET ON A CALENDER |
摘要 |
A calender for producing packing sheets has a heated cylinder of large diameter and an unheated pressure cylinder of smaller diameter which is movable toward and away from the heated cylinder to vary the width of a gap between the cylinders. A plastic mixture plasticized by a solvent is fed to the gap between the cylinders and is formed into a sheet on the heated cylinder, where it is vulcanized. Two temperature sensors on a common support are positioned to measure the temperature of the outer surface of such sheet and transmit the temperature measurement to a procesor which is programmed to control operations of the calender. A further sensor measures the thickness of the sheet on the heated cylinder and the thickness measurement is transmitted to the processor as a further parameter in control of operation of the calender.
