Method of regulating the feeding of a calender for plastics material, and apparatus therefor.

摘要

Method and apparatus for regulating the feeding of a calender for plastic material by the formation of a roll 5 between the feed cylinders of the calender. The material, issuing from an extruder 6, is conveyed by an orientable distributor 4. An electronic camera 23 emits towards a control box 27 an image divided into three areas which is analysed there. The detection of the deficient areas of the roll causes the throughput of the extruder to be acted upon by way of the line 29, and the speed of displacement of the distributor to be acted upon by way of the line 31. Application to the regulation of the feeding of calenders. <IMAGE>
