Edgebander LUMINA 1586: Laser Edging Technology

Our new LUMINA series offers a unique combination for processing panels: Two systems for perfectly invisible joints. The GluJet glue application system for standard use of PUR glue and the LTRONIC, the new laser edging unit from HOLZ-HER, are unbeatable in terms of speed and cost efficiency.

The LUMINA 1586 premium model with two cutter units allows processing of solid wood edging with thickness up to 15 mm (optional 20 mm). The LUMINA 1586 grooving serves for fully automatic grooving in the vertical and horizontal direction. With this machine, the groove position and groove depth can be set fully automatically on two NC servo-axes. The standard equipment on the LUMINA 1586 flex includes a corner buffing unit for perfect edge finishing without any subsequent work.

Adaptive package for intelligent automation:
The optimized, automatic control for the extensive pressure adjustments with plausibility checks allows HOLZ-HER to realize automatic glue quantity control matched to the specific requirements. Moreover, an adaptive trimming blade automatically adapts the pressure of the trimming blade to the edge thickness. Finally, an adaptive pressure unit optimally adjusts the pressures of the individual pressure rollers to the specific application for perfect results every time. This reduces adjustment errors and reject quotas to a minimum.

SYNCHRO edging feed:
The edge feeders with SYNCHRO drive.

With its synchronous adaptation to the feed rate, this feeder guarantees short intervals between workpieces and simultaneously optimizes edging protrusions. Small feed angle thanks to nozzle design – easy feeding of solid wood edging up to 15 mm.

The LTronic change-over unit has its own edge feeder with optimum feed angle for activation of the functional layer on laser edging.

Jointing cutter:
Cut edgings often have small tears in the top layer. The jointing cutter unit ensures perfect glued surfaces and prepares the panels for the gluing process. Equipped with ProLock quick-change flange, diamond tipped cutters (dia. 70 mm).

Including height adjustment for optimum utilization of cutters.
With new symmetrical diamond tipped cutters (dia. 100 mm) for maximum joint quality and long service life. Automatic height adjustment with two NC servo-axes (optional).

Standard on LUMINA 1588 performance

LTronic - laser edging change-over unit:
LTronic laser edgebander

The LTronic laser edgebander was developed especially for the LUMINA series and processes all edging with functional layer on the market. Two different NIR modules are available for processing laser edging:

NIR module for edge heights up to 23 mm (standard)
NIR+ module for edge heights up to 45 mm (optional)
(NIR = Near Infrared Radiation)
Switch it on and it's immediately ready for use – the new Ltronic unit does not require a heat-up time or any heat-up phases during the machining process. In addition, the complete system operates absolutely silently which is a clear advantage for the user compared to other systems. Moreover, cleaning costs are minimal. The integrated protective plate on the NIR module needs to be briefly cleaned just once per week.

A highlight is the edging library completely integrated into the control. All of the very latest co-extruded and subsequently coated edging are already stored here as a factory-provided item and can be simply selected by the user via the standard touchscreen. Each laser edging needs a specific energy entry, which, by way of an example, depends on the edge thickness or the color. After the selection is made, Ltronic automatically adjusts the respective energy requirement. HOLZ-HER takes perfect care of all of that with its edging library.

Glu Jet automatic - change-over gluing station:
Automatic replenishment -
The pressure cylinder presses the cartridge or granules against the heater elements. After reaching a certain position, the sensor sends a replenishment signal to the control. As long as glue is being applied to a workpiece, charging is delayed until the work is finished. The pressure cylinder retracts automatically, a new cartridge or fresh granulated material is gravity fed from the cartridge supply shaft into the heating chamber where it is again pressed against the heating elements.
Purging hole for automatic cleaning system – e.g. cleaning out PUR glue.
The Glu Jet automatic is attached to a set-up carriage alternating with the LTronic unit as a glue application system with automatic change-over. Change-over is accomplished within a maximum of two minutes by a high precision interface with HSK chuck and CNC technology.

Glu Jet XL - glue application station:

High melting capacity for even higher feed rates and thicker panels.

With the optional Glu Jet XL, you can process 2 kg PUR glue cartridges, which are significantly more economical than conventional PUR granules or the smaller 300 g PUR glue cartridges. This investment amortizes itself quickly for companies using more than approx. 500 kg of PUR glue per year, i.e. customers with an average glue consumption of approx. 2 kg per day. This corresponds to a processing quantity of approximately 400 - 500 running meters per day. The savings for glue costs alone already amortize the machine during the second year.

As accustomed from the Glu Jet, the heat-up time is unbeatably short - now only 3 minutes for the Glu Jet XL. Naturally, the station can also be used for processing glue granules making it extremely flexible for HOLZ-HER customers and offering every user major competitive advantages.

The Glu Jet XL is attached to a set-up carriage alternating with the LTronic unit as a glue application system with automatic change-over. Change-over is accomplished within a maximum of two minutes by a high precision interface with HSK chuck and CNC technology.
