C) Application of GRECON HS 120
The GRECON HS 120 line is designed for throughfeed processing and finger jointing of short wooden components into continuous lamellas up to approx. 6,100 mm in length.

Used in the manufacture of:
- Furniture panels
- Countertops
- Construction components
- Mouldings and solid wood semi-finished products

D) Staffing and number of operators
The GRECON HS 120 line with ABB automatic loading (2 pallet cells, alternating operation) requires just one operator.

E) Production process
1. Pallets with pre-sorted wood components are placed in the loading cell.
2. The ABB robot picks the components from the pallets and feeds them onto the GRECON HS 120’s belt magazine.
3. The line machines the male and female fingers on both ends of the components in a throughfeed process.
4. The automatic glue applicator applies adhesive (monitored by GlueEye Vision).
5. The pre-jointing station assembles the pieces to the specified length.
6. The cross-cut saw trims the lamella to length and feeds it to the press.
7. The press compresses the lamella until the glue is fully cured.
8. Finished lamellas are placed on the scissor lift, quality controlled, and conveyed to the roller buffer storage.
