WEINIG CF and CF-H: Compact lines for specific requirements

WEINIG Kompaktanlagen

The CF series offers several possibilities in terms of execution. You can choose. Depending on what you want to produce, we offer you a system that is adapted to your requirements. The following options are available for the compact line CF:

1. CF 160 - 2 cycles/min.
The CF 160/2 is a continuous compact line that carries out shaping, gluing and “endless” pressing in one process. The maximum lamella width is 300 mm, the maximum cross section is defined by the 16 t thrust force.

2. CF 200 - 4 cycles/min.
The CF 200 - 4 is a continuous compact line that carries out shaping, gluing and “endless” pressing in one process. The maximum lamella width is 300 mm, the maximum cross section is defined by the 20 t thrust force.

3. CF 200/300 - 5.5 cycles/min.
The continuous compact line CF 200/300 - 5.5 is available in a 20 t and a 30 t design. The high performance of 5.5 cycles/min is achieved using servo-drives and proportional hydraulics. Any end length can be provided using electronic length measurement and cutting is done using the integrated saw.

4. CF 300/400 - 10/12 cycles/min.
This is a separate, vertical compact individual shaper combined with a 30 or 40 t cycle press. The pressing unit, which creates the pressure, is fed from the side which increases its capacity. Glue (PUR) is applied in the cross conveyor between shaping and pressing contact-free from the side with a monitoring system (optional). The cross sections with a maximum width of 310 mm are defined by the joint length and the maximum pressing force. It is possible to improve capacity further, by up to one pressing cycle, by choosing a downstream positioning saw.

5. CF 300/400 - 15 cycles/min.
The shaping unit (without gluing and pressing), combined with the contact-free glue application, directly before our extrusion press, provides an ideal design with maximum performance.

6. CF – H (horizontal)
The CF-H is a compact line that can be used to produce a horizontal finger joint, for example for timber house planks. Just as in the other compact lines, the shaping, gluing and pressing take place in one clamping process.

Technical Details

Vertical finger joint

The vertical finger joint is the most frequently produced type of finger joint in the world. It provides the highest performance in a packaged finger jointing line.

The vertical profile is mainly applied in constructive woodworking, but is also used for building windows and frames. It is has the largest glue surface and is therefore the most stable of all finger joints.

Horizontal finger joint (only in CF-H)

The positive-negative profile is the second most common profile in a shaper combination because the system only needs to be equipped with three scoring units instead of four and produces high quality visible joints.
The trapeze profile is also called “American Profile” because this finger joint originates from the US and is usually delivered with a finger joint length of 1/4 inch.

Horizontal finger joints are mainly used in furniture construction. The shoulder profiles provide, for example, table plates that look like parquet where only the straight butt joints are visible.

Top quality glulam in seconds

PowerJoint power: Thanks to the open design on one side, 2 x 15 connections per minute

At Weinberger in Austria, a glulam lamella is jointed every two seconds. However, output is not the prime objective. It is quality that counts.

Weinberger Holz in Abtenau recently commissioned a completely new system concept for glulam production. Two high-performance compact systems from the WEINIG GreconLine provide output of 30 longitudinal joints per minute. Normally, one strand is responsible for the flawless top layer and a second for the central layers. However, if the top layer is proportionally small, e.g. in the case of thick girders, both machines joint central layers. Second highlight: Since the finger jointing is only performed by one cross-cut saw, a WEINIG OptiCut Quantum 450, both top and central layer quality can be processed without a larger buffer of raw wood.

By extracting flawless parts from the raw timber, Weinberger has increased its surface quality to "unprecedented levels" in its own words. The "completely open construction on one side" was first used when finger jointing on both PowerJoint 15 machines. The wood is transported via cross conveyor directly into the processing area, where it is simply finely positioned before jointing commences. Weinberger is certain that compact systems have significantly higher pressing quality compared with extrusion presses. The individual clamping reduces jointing offset. A top priority for the quality-driven Carinthians.
