  • Bereitstellen
    von Holzlamellen EN     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.

  • Kantenbeleimung/
    Pressen von Holzlamellen EN     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.

  • Bereitstellen von
    Quer-/Längslagen EN     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

    The Kallfass CLT press joins single-layer wood panels into muli-layer wood panels with tolerance values of maximum 0.1 mm. Achieving this zero joint is guaranteed through a very high vertical pressing force in combination with a uniform pressure distribution across the entire panel surface. A pressing pressure of 1 N/m² can be built up even with a maximum panel width of 3.6 m. As an option, the press can be offered with additional transverse pressure when pressing wooden lamellas. The result is a clean, homogeneous product.

  • Presskuchen
    vereinzeln/schleifen EN     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.

  • 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.

  • Entstapeln EN Destacking

    Separation of single and multiple packages

    High performance and a high cycle rate

    TILT DESTACKING

    For separating single and multiple packages with and without intermediate sticks upstream of planing and sorting systems. The packages are received in a transverse direction by a lifting unit, pivoted through approx. 45° and conveyed on to the skid edge. Layer by layer, the timber pieces now slid over a skid edge (which can be flexibly adjusted) to even out distortions in the layer.

    Minimising setup times

    TILT DESTACKING OF DOUBLE PACKAGES

    Tilt destacking of double packages can halve setup times, minimising production costs as a result. The intermediate strips in double packages can be removed with the aid of a stick stripper (optional) and collected and sorted for further use or disposal.

    Entstapeln_Kippentstapelung_Mehrfachpakete

    Careful and gentle at a medium cycle rate

    VACUUM DESTACKING

    Vacuum suckers lift the topmost layer of a package and deposit it gently in a transverse direction on the conveyor. This careful handling is particularly suitable for avoiding surface damage to planed workpieces. The vacuum destacker is suitable for production lines with short to medium cycle rates.

    Longitudinally and transversely at a low cycle rate

    PUSH-OFF DESTACKING

    This destacking involves pushing the uppermost layer of a package to the downstream process. Pushing can occur in a transverse or longitudinal direction, depending on the space requirement. This destacker is used on production lines with a low cycle rate.

  • Mehrfachablängen EN Multiple cross cutting

    Flexible and efficient

    The ends of raw or planed timber workpieces are cut with millimetre accuracy to the desired fixed lengths in cross-cut saws. The workpieces can be processed individually or layer by layer. Powerful saw motors and feed speeds of max. 50 m/min ensure a high throughput.

    Several cutting programs can be stored to ensure maximum production flexibility, or data can even be imported from ERP systems and master computers.

  • Beschicken EN Feeding
    Continuity at high speed

    Continuous material supply

    FEEDING: Planing machines

    Whether in layers or destacked, transverse or longitudinal, a continuous supply of timber is vital when feeding machining processes such as planing or sawing. Accelerating rollers ensure high feed speeds. The use of a slow-down belt is necessary as of a speed of 150m/min to decelerate the pieces after planing.

  • Bündeln EN Bundling

    Greater stability during handling

    BUNDLING: Sticks and boards

    Bundling involves the joining of individual timbers to form a compact bundle. Bundles are easier to handle and have a greater degree of stability. This is a major advantage when, for example, stacking or during transportation. Between 8 and 11 bundles can be automatically strapped every minute, depending on the bundle dimension. A labelling option is available, either on individual boards or on the complete timber bundle.

  • Stapeln mit Umreifen EN Stacking with strapping
    Time-saving process solutions

    Fully automatic material flow

    STACKING: Shipping packages

    Stacking of timber (including in multiple lengths) can be realised with placement forks or vacuum lifters, with the timber being collected in layers and deposited layer by layer on the shipping package to be formed. Dispatch strips can be laid between several layers to stabilise the shipping package. Strip laying is automatic. Where necessary, the shipping package is stabilised additionally through final strapping. Squared timbers can be optionally included on the package underside, and the packages can be pressed hydraulically together if desired. Customers who do not wish to have stabilising strips (e.g. because the package only needs to be transported within the company) may avail of offset stacking.

    Stapeln-Versandpaket

    Effective air circulation, thanks to dry sticks

    STACKING: Kiln packages

    Wooden sticks are laid between each layer when stacking timber that is still damp in kiln packages. The intermediate sticks ensure adequate air circulation during drying and accelerate the drying process. The drying sticks are laid by stick magazines.
    Option: Workpieces of different widths can also be stacked with spacing with the aid of a servo slide.

  • Eintakter EN Single feed unit

    Reliable conveyor transfer

    SINGLE FEED UNIT

    The quality of individual boards cannot be assessed or measured without precise cycling in. Both the desired production speed and the homogeneity of the timber determine the cycling in process in this respect. With a consistent board thickness and production speed of maximum 80 cycles/min, individual boards are backed up and, using retaining pawls in combination with a plunger and acceleration conveyor, transferred individually to the next conveyor.

    Eintakter

    A soon as the thickness of the boards differs or higher production speeds are to be run, powerful TongLoader® units with a gripper system are used. Tong Loader® units can cycle in boards at a speed of up to 240 workpieces/min and are suitable for wet, dry and planed timbers.

  • Schüsselungsvermessung EN Warp measurement

    Automated quality optimisation

    WARP MEASUREMENT

    Following drying, the degree of warping of a board is measured with the scanner system and the board turned over if necessary before further processing. This ensures an efficient, continuous process sequence.

  • Leistenlegung EN Stick placement

    Automatic positioning

    STICK/BOARD MAGAZINES

    During stacking, wood packages need to be dried or stabilised for shipping with intermediate sticks. Magazine are filled either manually or automatically with sticks or boards by robots for this purpose. Dual magazines can be fitted for a second stick size. Automatic stick placement is monitored by placement grippers.

    Leistenmagazin

    Fully automatic stick handling

    MAGAZINE FILLING WITH ROBOTS

    Patented system!
    Time-consuming filling of stick magazines in this variant is realised by a robot in a patented process that carries out charging at a constant cycle rate and almost without personnel. A stick scanner can be optionally used prior to magazine filling that assesses the quality of the sticks. Only suitable sticks are subsequently separated, packetised and then prepared for robot filling.
