Trimvac Trim-Removal Systems, 1990 TAPPI Conference Proceedings
The rate of trim production in a paper-processing plant can surge to more than ten times the average rate. This presents a substantial challenge to a trim-conveying system.
In a concentrated trim-handling system where all trim is transported to a single repulper, the design trim-handling rate should not be determined based on the cumulative maximum design output of all winders. Instead, the effect of decreased paper machine speed during production of heavier paper grades should be accompanied by a proportional reduction in winder speed.
The development of winders is making the conventional trim-handling system obsolete. Vacuum trim-handling systems are replacing conventional trim-conveying equipment because of their ability to increase winder speed capacity, conserve energy, and reduce noise levels.
