Space and installation requirements:
- Required floor length: approx. 14 m
- Required width: approx. 10 m

Media supply requirements for the line:
- Electrical power supply 400 V / 3-phase
- Compressed air
- Chip and dust extraction
- Internet access (control and diagnostics systems)

C) Application of the GRECON HS 120 line
The GRECON HS 120 line is designed for through-feed finger jointing of short wooden segments into endless slats of up to approx. 6,100 mm in length.

Used in the production of:
- furniture boards
- countertops
- structural components
- battens and solid wood semi-finished products

D) Personnel and number of operators
The GRECON HS 120 line with ABB robotic feeding (2 pallet cells, alternating operation) requires only one operator.

E) Production process
1. Pallets with pre-sorted wooden elements are delivered to the robot loading cell.
2. The ABB robot picks items from the pallet and loads them onto the belt magazine of the GRECON HS 120 line.
3. The line mills male and female finger joints in a through-feed process.
4. The automatic glue applicator applies adhesive (monitored by the GlueEye Vision system).
5. The pre-jointing station assembles elements to the pre-set length.
6. The cross-cut saw cuts the endless batten to the desired size and feeds it into the press.
7. The press clamps the element until the glue fully sets.
8. Finished slats are placed on the scissor lift, undergo quality control, and are transported to the roller storage buffer.
