Milling machine :
Turbo milling combination
Type: FDL-F-205/600/500

Two combined milling machines in heavy-duty design with movable tables as workpiece support, guided by stable combined recirculating ball bushing and roller guide.
Each milling machine is equipped with a clamping station, the hogger and the milling unit.
Either the second or both routers are equipped with a gluing unit.
The cutters can be equipped with a scoring unit.
Conveyor belts between the trimming machines minimize package transport times and thus achieve a fast transport cycle.

In the clamping station, a pneumatic jogging device ensures that the timber is evenly aligned.
Horizontal and vertical pressure devices clamp the package.
The clamp is used to cut a reference edge on the workpiece.
This reference edge determines the length of the respective finger joint profile and can be adjusted.
The finger jointing is carried out by the trimming unit, the glue is then applied by a flank jet or roller glue applicator.

Transfer :
Transfer station
Type: ÜL WB 600/1000

Transfer station in sturdy welded construction with infeed conveyor, alignment stop, cross-pusher unit, turning device
with turning brush and outfeed conveyor as well as adjustment devices for optimum adaptation to different timber dimensions.

The workpieces milled in packs are transported from the milling table of the finger jointing machine onto the conveyor belt of the transfer unit and aligned flush with a stop.
The aligned timber bundle is moved by the cross-pusher unit in cycles at right angles to the infeed direction into the area of the turning device.
The wood bundle is separated either directly onto the discharge conveyor or turned through 90° and aligned with a fixed edge.
The discharge edge is adjustable to the timber dimension.
The separated timber is transported to the threading station via a high-speed conveyor belt.

Technical data:
Power consumption 2.5 kW
Compressed air volume 12 m³/h
Feed speed 75 m/min

Threading station:
Threading station
Type: EKK 205

Threading station with lateral chain guide for transporting the separated timbers.
The workpieces come individually from the transfer station and are fed via a fast-running belt to two laterally synchronized chains.
In combination with spring-loaded top pressure pieces, the guide chains ensure that the finger-jointed workpieces are brought together into an endless strand without any misalignment

Technical data :
Power consumption 2.2 kW
Feed speed max. 120 m/min

Feed :
Two-roller feed unit
Type: VE 225

The electrically driven feed unit consists of a pair of rollers with integrated frequency-controlled AC drum motors.
The upper roller is pneumatically controlled and pressed onto the workpiece
For transporting timber lengths or for positioning the timber. Controlled by a length measuring device or via light barrier scanning.
Fast and slow speed for precise positioning.

Technical data:
Power consumption 4.4 kW
Feed speed 30 to 90 m/min

Press:
Face press
Type: PASH CONTI 6100 (Conti A)

Hydraulic finger-jointing press manufactured as a heavy tubular steel construction with pre-flanged feed table, pneumatic braking device and length measuring unit.
The press itself consists of:
- 2 offset table levels
- 2 separately operating push-out systems
- a cross-cut station
- a press cylinder mounted on the front side
- and a top pressure system adjustable to the desired pressing length

Pressing of the pre-threaded individual timbers into an endless strand.
The finger-jointed timber is pre-pressed in the braking station.
The incoming timber strands are guided on both sides and spring-loaded.
The infeed of the timber strand takes place independently of the simultaneous pressing function.
The pressing length is entered via a length measuring system.
The cross-cut saw cuts the required length.
After the pressing process the timber is pushed out onto support arms.

Technical data:
Length 7650 mm
Width 1900 mm
Power consumption 5.2 kW
Compressed air consumption 500 NL/min
Suction volume 850 m³/h
Suction diameter 100 mm
Pressing pressure 6-12 t (depending on cylinder diameter and hydraulic unit)

Control cabinet:
Control cabinet
Type: SSK
Freestanding switch cabinet. Version to VDE, DIN, protection class IP54, fully assembled and ready for connection.
