WEINIG PowerJoint: The compact line for high standards

WEINIG Kompaktanlagen

1. PJ - 6 cycles/min.
The PowerJoint is a compact line with contact-free glue application. Shaping is done from top to bottom, which guarantees the best finger joint quality. Transporting the “freshly” pressed finger joints only occurs in the production direction, which means that the load application on the joint is lower. Another benefit is that the timbers pass through the middle of the line. This means that there is a very good distribution of thrust force and the best use of tools.

2. PJ - 8 cycles/min.
The PowerJoint 8 is the fastest line in the compact construction style (shaping/gluing/pressing in one clamping process). The increase in performance is achieved by feeding the line from the side. The timbers are immediately clamped in a central position and then pass through the shaping, contact-free gluing and pressing. The scoring unit, shaping spindles and the glue nozzles for contact-free gluing are integrated into the shaper head. PowerJoint-8_Fräskopf_16_9.jpg

2. PJ - 15 cycles/min.
The ultimate increase in capacity can be achieved using the PowerJoint family by separating the shaper unit from the gluing and the press. In this way a PowerJoint with up to 15 joints/min can be obtained. With the individual components working simultaneously an increase in capacity of almost 100% compared to PowerJoint 8 is possible.
We have also integrated the benefits of PowerJoint here, for example, conveying the work pieces only in the output direction (no reverse positioning), indirect gluing and production of an endless phase.

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.

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.
