    Provision of timber lamellas

    Reliable process preparation

    The timber lamellas are first destacked by a vacuum and then separated into layers. Unsuitable workpieces can be identified and ejected with the aid of quality, strength and moisture measurements. In the next step, the lamellas are trimmed on the left and right at the front and in a transverse direction before being fed to the finger jointing system with the throughfeed press. The finger jointed lamellas can then harden on the buffer section of ca. 25 m before being fed to the planing machine.

    Edge glueing / pressing of timber lamellas

    Clean bonding to form single-layer boards

    After planing, the timber lamellas are cycled in the direction of the board press. Glue is first applied to the edge in the press before the glued lamellas are pressed together to form single-layer boards. The longitudinal layers are already trimmed to the correct width on being transferred to intermediate storage.

  • Erzeugen von Querlagen EN Creating transverse layers

    Precision cutting without scrap

    Single-layer boards intended for transverse layers are automatically trimmed to the desired dimension, stacked and transferred to an automated store using a crane.

    Provision of transverse / longitudinal layers

    Maximum process reliability

    The provision of transverse and longitudinal layers of single-layer boards encompasses a variety of individual processes such as vacuum stacking, aligning with subsequent turning of the boards (the better side of the board should be upwards during formation of layer packages) and trimming of boards in a transverse direction with downstream cleaning and stacking. Stacking of boards creates a material buffer that enables continuous supply of the glueing station, avoids stopping times and thus ensures a high degree of process reliability.

  • Presskuchen bilden EN Creating layer packages

    Optimum process utilisation

    When creating layer packages, individual layers of single-layer boards are glued in a cross pattern to achieve a high degree of dimensional stability. Glue is applied uniformly over the entire board surface using a glueing portal. Following every glue application, a vacuum portal crane lays the next (alternating transverse or longitudinal) layer precisely, edge to edge on the glued board. The board structure of a layer package should have at least 3 layers and can be a maximum of 600 mm thick. In the case of a thin layer structure, several board assemblies can also be laid on top of each other with a dry joint in each case and, simultaneously, pressed to achieve better process utilisation.

  • Pressen EN Pressing

    Constant pressing force

    In order to achieve a clean pressing pattern, a uniform pressing force must be ensured when pressing the board assemblies. The hydraulic system plays an important role in this. The Kallfass hydraulic concept is based on quasi-isobaric pressing that enables the generation of both vertical and transverse pressure. Pressure control ensures a constant pressing force of 1N/mm² over the entire board surface, even where a maximum board width of 3.6 m is involved.

    Separating / sanding layer packages

    Constant material flow

    Following pressing, individual multi-layer panels laid on top of each other are pushed again on the dry joint and fed individually to the sanding process. In the final processing step, the multi-layer panel is transformed into a prefabricated timber construction element in portal processing centres by cutting out openings and ensuring surface cosmetic treatment.

    The added bonus for your success! This equipment allows you to enhance your product quality while simultaneously reducing changeover times and personnel costs.

  • Wenden von Einschichtplatten EN Turning single layer boards

    Attractive product appearance

    TURNING single-layer boards

    Single-layer boards can be turned after destacking and aligning to improve the appearance of the final product. In this way, the more attractive side of the board faces outwards when creating layer packages. The final result is a perfect multi-layer panel.

  • Wenden von Großplatten EN Turning large panels

    Safe handling

    TURNING large panels

    It may be necessary under certain circumstances to process the large panel from both sides in the machining centre. The board is turned after a pass for this purpose and fed into the machining centre again. To avoid risky turning with a crane, Kallfass has developed a turning device that can also pick up large panels without breaking them and lay them gently on the conveyor.

  • Festigkeitsmessung EN Strength measurement

    Unambiguous classification

    STRENGTH MEASUREMENT

    Leading makes of multisensor scanner systems are used for strength sorting, measuring the timber precisely and classifying it at high production speeds pursuant to customer-specific quality requirements before it is forwarded on for planing, cutting to size or to sorting systems.

  • Feuchtemessung EN Moisture measurement

    Consistent quality standard

    MOISTURE MEASUREMENT

    The water content of the timber is measured in mere seconds and without contact during moisture measurement. The analyser can be integrated at a flexible point in the production process. In the event of exceeding or undershooting the defined moisture level, the boards are marked behind the measuring head and rejected if necessary. Only timber that conforms to the desired classification is processed further, ensuring a consistently high quality standard.
