The Marchesini MC 820 is an automatic case-packer machine for collation and insertion of single and collated cartons into the case, the case closing is done with not overlapping adhesive tape.
Software, mechanical and electronic parts have been completely refurbished. The machine is CE certified and complies with the existing safety standards.
The machine is composed of three working sections: cartons collation, case feeding and closing. The Balcony design improves accessibility, maintenance and cleaning operations. Changeover is made easy by means of quick lock size parts with reduced use of tools.
