The ALstep Labeling head is a compact-sized and low-cost applicator for self-adhesive labels, which can be easily integrated into already existing packaging lines. ALstep is based on a robust, reliable mechanical structure; it can be fitted into particularly restricted areas, also thanks to the side access web threading allowing a fast, easy label change over.
ALstep labellers can hold label rolls up to 300 mm of diameter for a long operating time; it is equipped with a separate control box with cooling fan which makes it possible to operate it in harsh industrial environments.
ALstep 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. Such parameters are stored on EEPROM and automatically recalled by switching on the machine.
In more detail, the following functions are available:
pre-dispensing adjustment;
adjustment of label dispensing speed;
labelling delay adjustment;
automatic recovery of missing labels;
pieces counter;
end-of-roll alarm and web break alarm;
contact for connection to other systems.
Additionally, the ALstep automatic labelers can be equipped with an array of optional devices to solve
specific labelling problems, such as:
Hot foil printing unit;
Thermal transfer printing module (ALstep T model);
Pneumatic and air-blow applicator;
Checking device for near end of reel;
Speed control through encoder;
Label sensor for transparent material.
ALstep labellers are also provided 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 label feeding is still controlled by a stepper motor, while the control panel makes it possible to adjust the main functioning parameters (speed and predispensing) by means of digital indicators (contraves), providing an alarm signal in case of web break and end of roll. A label sensor for transparent material is optionally available.
Thanks to its professional resources, ALTECH is able to provide skilled technical service for any labelling problem, design complete plants and assure maintenance and service for its installations throughout Italy.
