Micro-Embossing Machine ALF-300ME
Micro-Embossing Machine
ALF-300ME
Automatic rewinder for converting of aluminum foil high-precision embossing of various designs and smooth web tension.
The main feature of the machine is a motorized steel engraved roller with the embossing pattern driving the wool-paper roller. It is interchangeable and can be easily replaced. The machine is perfectly suitable for frequent design changes.
The machine includes the unwind unit of the mother rolls, the embossing assembly with associated drive and control devices and the rewinding group for the embossed material.

EMBOSSING UNIT
EMBOSSING UNIT
This unit is designed for the creation of an embossed surface on the foil web during the process of JR rewinding.
How does it work?
A servomotor rotates the steel shaft, and also rotates the paper countershaft in the direction opposite to steel shaft rotation via a reducer. The surface of the steel shaft has an embossing pattern engraved on it. The foil web is unwound from the JR at a specified tension, and is then stretched between the steel shaft and the countershaft that is pressed against it. During the process, the steel shaft presses the foil into the surface of the paper countershaft, leaving an engraved impression on the foil. Along with embossing, both shafts pull the foil web through the unit at a specified speed.
ADVANTAGES:
The option of applying a customized embossing pattern.
FILM BREAK MONITORING SYSTEM
FILM BREAK MONITORING SYSTEM
If the film breaks, the rewinding process is stopped automatically. The sensor measures the length of already wound film and displays the corresponding notification message. After rethreading, the system recalculates the length (weight) still to be wound, which allows the machine to rewind the target length or weight of the film.
ADVANTAGES:
Decrease of production waste quantities
Elimination of prolonged delays due to fast response to the abnormal situation
REVERSE REWINDING FUNCTION
REVERSE REWINDING FUNCTION
This function makes it possible to wind the film off the JR if it was wound on the drum.
ADVANTAGES:
Decrease of production waste quantities
Prevention of mechanical failures of the machine components caused by accidental film winding on the drum
Prevention of mechanical failures of the machine components caused by film removal from on the drum
Time savings due to elimination of necessity to remove the film from the drum
