Angular system

Double-End Tenoner

for a renowned German construction materials manufacturer at the production site in the US

Customer requirements

The objective is to process construction panels that feature a very brittle surface on both sides into tear-free panels cut-to-size on four sides to be transferred to surface printing. The high predefined cycle time requires smooth passage and processing of the panels during their passage through the system.

Application solution

MHF has already manufactured, delivered and commissioned several systems for the processing of construction panels. This is why we were able to convince the renowned construction materials manufacturer by our concept with trimming saws including scoring technology for longitudinal and transversal processing as well as up- and downstream conveying technology. The angular transfers and trimming saws were individually adjusted to customer-specific requirements at the production site in the US.

Customer satisfaction

For more than one year now, with this manufacturing equipment the customer has achieved tear-free edge quality while the rectangularity of the panel is well within the required range.


Production sequence

After all guard doors and protective caps have been closed, the machine operator selects the planned article number on the panel. The system is then automatically preset to the corresponding panel length, widths, and height.

The machine operator positions the construction panels, coated on both sides, onto the non-driven roller conveyor against the longitudinal stop on the right, until the top roll pressure of the longitudinal saw has reached the panel and conveys it automatically through the system.

Once the incoming panel has left the longitudinal stop on the right, the next panel can be loaded. A fence protects the hand from reaching into the space between top roll pressure and panel. The construction panel runs through the longitudinal profiling equipment and is cut to the preset width at the longitudinal edges. Any protrusions are completely cut.

After the panel has left the top roll pressure, it is accelerated and conveyed to the transversal stop at the end of the roller conveyor. The transversal stop had also been set to the excess length to be cut off on the following profiling machine during machine setting. Timing belts lift the panel and align it in transversal direction against two stop panels coming up.

When the panel is positioned in front of both stops, the stop panels swing out of the way and the panel is conveyed by the transversal saw and cut to the predefined length. Subsequently, the panel is conveyed by means of timing belts and placed on the roller conveyor. Through minor tilt of the rollers, the panel is conveyed to the stop ruler and transported in longitudinal direction via roller conveyors. 

During this process, it is guided through a printer and a labeling machine. These additional modules were supplied by the customer and integrated in the systems engineering

At the end of the production line, behind the protective fence, is a non-driven roller conveyor from which the panels are removed manually. In case removal is delayed, sensor technology will shut down the machine.
