Optimierung des Klebstoffauftrags im Sackbodenleger. Tl.2. Intermittierender Auftrag auf gefaltete Papierbahn unter Verwendung von Rasterwalzen


The application mechanism of a commercial cold water soluble starch glue on stepped and folded sack papers has been studied on a pilot machine of bottom gluing. The machine was equipped with a conventional gluing station. The influence of the relevant process parameters e. g. paper velocity, speed and speed ratio of rolls, roll gaps, material and surface characteristics of the stereos, glue viscosity etc. on the time- and position-related glue thickness uniformity has been evaluated. The relations between the parameters have been quantified and from the date the glue thickness uniformity during the application has been optimized. The results make possible the determination of suitable parameter ranges for the thickness control systems. In part 1 (issue 4/1988) the results of the investigations of a continuous glue application with smooth, not interrupted application rolls on not stepped papers are discussed. In this part 2 the intermittent glue stereotype application on folded and stepped sack papers are treated
