Edgebander LUMINA 1380: Your Start with HOLZ-HER

Our new LUMINA 1380 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.

Here is what the HOLZ-HER LUMINA 1380 offers:
Invisible Joint with Laser Edging
Waterproof Invisible Joint
Adaptive Package for Intelligent Automation
Intuitive Operation with Touch Screen

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.

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.

Jointing Cutter
Cut edges 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, tool dia. 70 mm.

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

LTronic - laser edging change-over unit
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.

Motor-driven pressure unit:
Pressure unit with synchronous drive and automatic adaptation to feed rate. Straight and tapered pressure rollers for perfectly glued joints.

With NC servo-axis for motorized adjustment to specific edge thickness:

Pneumatic trimming unit:
For straight or chamfered trimming on thin edging; a standard feature allows this unit to be pivoted to 10 degrees pneumatically. High quality version with stable cast iron pillars.

Sawing motors each with two guides for precisely trimming off protruding edging.

Cutter Unit:
Heavy-duty floor-mounted unit with shock-absorbing bearing and large sensing rollers for perfect results even at high feed rates.

100% repetition accuracy at the touch of a button based on zero-clearance mechanisms and six high precision NC servo-axes. Horizontal sensing with angular sensing rollers with chemically applied nickel plating developed especially for processing modern, high gloss edging.

In multifunction package with multiple stage tool (optional on LUMINA 1584 and higher models).

Copy cutter unit:
Copy cutter unit with four NC servo-axes as standard feature

For cutting top and bottom longitudinal edges, copy cutting on vertical edges at front and rear ends, corner rounding and postformed corners. - Work height up to 60 mm workpiece thickness

Unit adjustments on linear guides with central lubrication. With standard blast nozzles in front of sensing rollers to blow away chips in front of sensing areas. Including shelf program for optimum processing of shelves with rounded edges.

Automatic pendulum sensor copies rear without material protrusion and leaves the optimum edge protrusion for the longitudinal edge for subsequent machining with the radius scraper.

In multifunction package with revolving tool magazine (optional on LUMINA 1584 and higher models).

Scraper unit:
