    摘要: The present invention is directed to a process for determining the thickness of adhesive layers placed on book block backings by initially measuring the position of a backing before adhesive is applied to establish a reference point, applying adhesive, then measuring the position of the backing with adhesive to determine the thickness of the adhesive layer. Distances to a standard reference plane may be measured both before and after application of the adhesive, and the differences in respective positions may be used to determine thickness of the adhesive layer. Two such measurements before and after adhesive application are recommended, with the readings averaged to give a mean thickness of the adhesive layer. Measurements are preferably carried out by means of laser beam technology, with the aid of a beam splitter.
