Minimization of processing costs by significant reduction of web breaks and hence machine downtime
For the PM4 paper machine in its paper mill in Venizel, SAICA is making full use of the web inspection system (WIS) and web break monitoring system (WBM) from ISRA VISION. What is remarkable is the system's short amortization period after only a mere year and half as well as the timely reduction in the number of web breaks. In addition, the system also helps to optimize manufacturing processes.
The paper market in France is extremely competitive. Ten different companies produce around 3.3 million tons of corrugated medium and liner paper on a total of 19 paper machines. One of those manufacturers is SAICA, a leading producer of paper-based packaging in Europe and the market leader in Spain. The packaging operations within this group procure the majority of their raw materials from their own paper factories.
SAICA's Venizel plant, located 100km north of Paris, is where their brown corrugating medium and liner paper between 115 g/m2 and 250 g/m2 is produced. This paper is further processed in the group's own corrugated paper factories as well as in those of third parties. The requirements of corrugated paper manufacturers which paper producers must fulfill relate in particular to the paper's ability to be machine processed without breaking while guaranteeing good product quality. "Our main objective is to be able to supply paper without any major defects such as holes, spots or edge breaks, which might be the cause of breaks in the corrugated paper machines" emphasizes Renaud Guilianelli, Mill Manager at SAICA in Venizel.
