GREEN FINISHING OF LEATHER WITH RELEASE PAPER SYSTEM NO-STOP 24/24

GREENFINISH is the innovative release paper finishing line with very low environmental impact. It is the first system to use the GREENSTARs roller coating machine to coat the thermo-adhesive on both corrected grain and full grain leathers.
The standard line is complete with accumulator and allows non-stop processing 24/24, ideal for tanneries that have large production batches.
The unwinder, the rewinder and the cleaning machine unit are designed in separate modules to eliminate any type of interruption or downtime: on request, it is possible to increase the working speed, lengthening the infrared tunnels and adding a second head for the finishing of coarse grains.

The line combines efficiency and eco-sustainability aspects:
- combine efficient and ecological performance;
- it creates a covering effect that evenly covers the surface of the leather, even on the most defective examples;
- minimisation of negative environmental impacts with the reduction of energy waste and the elimination of atmospheric emissions.

 

Among the main innovations made by this finishing system are:
- the possibility of finishing any type of leathers, even those buffed or with defects, with a single step with considerable benefits in reducing costs and working times
- the possibility of obtaining an almost completely finished leather that can be customized with replacements and fixatives
- compared to spray and roller finishing, the reduction of finishing steps which, consequently, reduces the risk of contamination to a minimum
- the possibility of reusing the release paper, now consumed after 30 passes, also in an alternative way, i.e. as a matrix for products with smooth base (drummed or with larger prints).

 

THE SYSTEM
1.DETACHING CONVEYOR BELT: table to detach leathers from release paper.
2.RELEASE PAPER CLEANING MACHINE: unwinder and rewinder of the adhesive paper to remove residues of coated film after the detachments of the leathers.
3.REWINDING UNIT WITH DOUBLE COILS AND WITH CENTERING motorized unit for rewinding the clean release paper.
4.TWO-STATION FIXED UNWINDER: to unwind the coil of release paper which feed the finishing line.
5.JOINING TABLE: for paper cutting and locking.
6.PNEUMATIC ACCUMULATOR 30 m: storage of release paper to feed the line during the roll change.
7.GREENLINE-R ROLLER COATING HEAD: roller coating machine to coat the film on release paper with two rollers.
8.INFRARED DRYING TUNNEL: double chamber infrared drying tunnel.
9.GREENLINE-2R ROLLER COATING HEAD: roller coating machine to coat the film on release paper with two rollers.
10.DOUBLE STARDRIER-IR INFRARED DRYING TUNNEL: infrared tunnel to dry the chemical on the leather.
11.LAMINATION CALENDER: low pressure rotary press for release paper-leather lamination.
12.STARDRIER-IR INFRARED DRYING TUNNEL: infrared tunnel to dry the chemical on the leather.
13.GREENSTARs ROLLER COATING MACHINE: roller coating machine to coat the adhesive on the leather.
