1.6. Description of the machine
This gravity feed slicer is a semi-automatic food slicer. The carriage is either moved backward and forward
automatically or the automatic drive of the carriage can be disengaged for manual operation.
The blade is driven electrically with a 1-phase or 3-phase gear motor. This gear motor is maintenance-free
and air-cooled. By means of a special air circulation the warming up of the motor is very low, especially
around the blade.
The automatic carriage is moved by a strong d.c. motor.
The food product is pushed against the blade by its own weight (gravity).
The material used in the food zone corresponds to all requirements of food hygiene.
The complete machine body, the thickness plate, the blade guard and the carriage are made of stainless
steel. The blade is hard chromed.
All visible bearings as well as open sliding surfaces are lubricated only with lubricant suitable for food
zones.
Model ATM-3 / ATM-3 S: For switching the machine on and off there is used a double red /green push
button which is illuminated when the machine is switched on.
Model ATM-3 E / ATM-3 ES: For switching the machine on and off there is used a double red/blue push
button with integrated signal lamp on a key board. When the machine is switched on the signal lamps are
illuminated.
The red main button fulfils the requirements as emergency stop switch.
With the other push buttons of the key board there can be adjusted different functions for the automatic
operation.
Self-starting of the machine after a voltage drop is avoided by the electric control.
The carriage can only be tilted aside when the automatic drive is disengaged and the thickness plate is
closed completely. When the carriage is tilted aside, the thickness plate is locked in this position.
The protecting and security equipment as well as electrical and mechanical components correspond to
regulations in force.
