Equipment for making a dual component pack tray

摘要

The installation has gluing pads (5) with a porous material block (5b) filled with glue e.g. acrylic glue using diffusion phenomenon and to deposit the glue using compression phenomenon. The pads are mounted on a central support structure (4) via an operating unit (6). The unit operates the pads between a deployed position, in which the pads contact with a gluing area to apply the glue on the area, and a folded position, in which the pads are remote from an outer envelope (1) to permit inward and outward movements of the envelope respectively inside and outside a gluing station (2).
