Closing System for Top Load Cartons with One Flap

The ELS systems are designed for the sealing of filled one flap boxes with a highly compact balcony design. The DIENST ELS system automates the closing processes of filled boxes with attached cover.

Function Principle

The boxes arrive in irregular distances or in a row and get synchronised into the required pitch.

Before the cover flap is being closed, the dust flaps are folded and glued with hot-melt if necessary.
