SELF-ADHESIVE LABEL APPLICATOR ALSTEP
The ALStep is a compact-sized and low-cost applicator for self-adhesive labels which can be easily integrated into already existing packaging lines. The ALstep is based on a robust, reliable mechanical structure. It can be fitted into particularly restricted areas, thanks to the side access web threading allowing a fast, easy label changeover.
The ALStep can hold label rolls up to 300 mm diameter for a long operating time and is equipped with a separate control box with cooling fan which makes it possible to operate it in harsh industrial environments.
This system comes in both S and M versions, for label widths up to 100 and 200 mm respectively. Its maximum label dispensing speed is as high as 30 m/min. (20 m/min. in the M version) thanks to a microprocessor-controlled stepper motor enabling the operator to enter all labelling parameters by means of the display and function keys.
In more detail, the following functions are available:
- Adjustment of label dispensing speed.
- Pre-dispensing adjustment.
- Labelling delay adjustment in millimetres.
- Automatic recovery of missing labels.
- Progressive counter.
- End-of-roll alarm and web break alarm.
- Contact for connection to other systems.
Additionally, the ALStep can be equipped with an array of optional devices to solve specific labelling problems, such as:
- Hot foil printing unit.
- Thermal transfer printing module.
- Pneumatic and air-blow applicators.
- Near-end-of-roll sensor.
- Speed control via encoder.
- Label tracing by thickness capacitive sensor.
The ALStep is also available in the E (Economical) version for label widths up to 100 mm at a maximum speed of 15 m/min. It is ideal for the applications where cost reduction is a crucial requirement.
The control panel makes it possible to adjust the main functioning parameters (speed and pre-dispensing) by means of digital indicators (contraves), emitting an end-of-roll or web-break alarm signal. A label sensor for transparent material is optionally available.
