QCS: what it is, its importance in production processes
A Quality Control System (QCS) refers to a system used to measure and control the quality of sheet movement processes. In general, it deals with the measurement and control of one or more properties over time in a single dimension. A basic QCS generally includes measurements of basis weight and moisture profile as well as the average basis weight of the paper web and moisture control related to these variables. Caliper is also one of the basic measurements.
Other commonly used measurements include ash content, colour, brightness, smoothness and gloss, coat weight, formation, porosity, fibre orientation and surface properties (topography). The QCS is used in paper machines, cardboard machines, tissue machines, pulp dryers and other textile, plastic or metal film processes.
S8000 - QCS O-Frame
O-Frame system for measurements on paper and cardboard. The closed bridge guarantees high performance in terms of scanning speed. The structure is fully protected by stainless steel coating and pressurised. A sophisticated 3D alignment system ensures the reliability of the sliding system over time.
