LHF press line

The Kallesoe high frequency (radio frequency) equipment for the production of glulam is a particularly effi cient production line capable of operating with very short pressing times for highest output.

The high frequency line can be individually adapted and will typically, as illustrated above, consist of a double roller conveyor, a lay-up system with cross conveying and setting-up device and a high frequency press with infeed and outlet tables.

This production line offers you the most efficient and reliable high frequency system on today’s market, ideal for the production of glulam beams of up to 27 meters length.

Kallesoe Machinery's high frequency plant has been designed to achieve the highest reliability and speed. The following presents three specific details of the press plant, details as to ensure the best and fastest cross conveying, laying-up and pressing of the wood.

Billede 1 Hf Rullebord

The line is fed by a high speed dual roller conveyor, allowing the lamellas to be conveyed to the lay-up system at a quick pace. The lamellas are cross conveyed in two steps, in order to prevent collision during transport.

Leaving the roller conveyors, the lamellas are cross conveyed to the lay-up device, either directly or onto intermediate chain conveyors between.

After the cross conveying, the glued lamellas are raised on edge, straightened and joined together on a belt conveyor where they are effi ciently held in place, while subsequent lamellas are added.
When the charge is completed it is led to the inlet conveyor

Billede 2 Hf Oplaeggersystem

The inlet conveyor in front of the HF/RF-press is equipped with side supports to prevent the lamellas (short lamellas especially) from overturning during transport into the press.
The complete press line is automatically controlled by a central control system in which all data from the glue application and pressing processes are collected and saved.

The press construction is sturdy and strongly built and equipped with a high-performance and reliable high frequency generator, ensuring a rapid curing of the glue.

Billede 3 Hf Presse

In order to optimize the production line further to an order-based production, the press can be manufactured with semi-automatic setting of the press height enabling different products to be pressed in rapid succession, and with side pressure widths from 1280 mm and down to 240 mm, so that single and few beams can be produced by themselves according to order.
Flexibility is the keyword.
