The EP 48 PRO applicator delivers accurate, consistent hot melt adhesive application to book spines. Precise
control of adhesive application allows use of only the amount of adhesive necessary for the optimum bond
without the need for over application. EP 48 PRO applicators provide on-demand adhesive application so even the first book produced after a spine width change is saleable. Changes in adhesive viscosity and/or spine thickness are automatically adjusted for with volume compensation technology. Continuous automatic adjustment for accurate, real-time volumetric PUR application provides consistent, reliable spine gluing: adhesive thickness, width, and length end-to-end of the book.
