DIENST DLS I/III
System for Closing Top Load Cartons with Three Flaps
The DLS systems are designed for the sealing of filled three flap boxes with a highly compact balcony design. The DIENST DLS 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 spaced fitting to the needed pitch. On both models the front flap is closed before the side flaps.

Model DLS III operates without lugs after a 90° turn with no change in direction.

Request now- individually selectable machine speeds for safe closure processes.
- format changes by spindles with counters.
- ensured reproducibility of all machine settings by editable save of all setting values.
- clearly structured operation panel with self-explanatory display and visualisation of the functional sequence.
- smooth material treatment by adapted motion profiles of servo drives for every format.
- permanent data storage of all servo drives with trend analysis to prevent down-times.
Hot-melt application units are used for both model types to close the boxes.
The DIENST DLS I system is an angular closing machine in L-design and enables a large end flexible format size range.
The DIENST DLS III System on the other hand is designed as a straight version and turns the box 90° for glueing with no change in direction. Due to the lugless design high performances are possible.
The hygienic balcony design enables efficient production also in environments with high humidity.
- the maximum output of DLS I systems is 120 boxes per minute, of the DLS III system up to 200.
- base frame out of stainless steel.
- servo technology prevents vibrations and assures a smooth and dynamic run.
