Peel and Seal

EMU free-standing, high-speed, production line to apply pre-gummed hot-melt tapes to the flap of an envelope

This machine handle envelopes from 4-1/8 x 9-1/2 up to 12 x 16” in all style and in all grades of paper.
The photo is of an EMU tape line that was configured for three tape heads; one for a tear strip and two heads were for the closure, or sealing tape. All three heads were for pre-gummed pressure sensitive adhesive. The two heads for the closure tape were synchronized so that when the spent, or depleting, roll neared the core, the other tape head would engage. Therefore, non-stop operation at a line speed up to 400 envelopes per minute can be achieved.
