Due to the quality inspection, some panels are sent to a repair line (Poly Patch), where their faults are corrected. The panels, ranked by level of quality, are then automatically organized into piles. A certified operator then inspects and defines (classifies) the level of each panel. After the panels have been adjusted in size, they are subject to a blow detector test to check the perfect gluing of each panel layer. The type of finish depends on the desired product in terms of meeting the demanding market’s requirements. The laminated wood panels finally undergo a finishing process whereby the edges are trimmed and the two outer faces are sanded for a smooth finish.
These sheets and manually peeled strips are automatically transported to the wet veneers deposit area.įinishing operations consist of squaring, fixing, sanding and classifying.

Smaller sized pieces are taken to a manual classification table, where operators classify pieces by quality and width. When the scanner detects a defect in the panel, it instructs the clipper to make a cut before and after the fault, producing smaller-sized sheets. The system is comprised of a camera, a light source (which allows on-going analysis of the veneer panel that passes underneath the instrument), a rotary clipper and a control panel to move the clipper and cut the continuous veneer sheet based on the results of the scan. The continuous wood sheet from the lathe (veneer) is scanned to detect faults, knots or breaks. When the blade reaches the rotating trunk, it starts to peel a continuous, thin sheet of wood with the desired, calibrated thickness.Īfter the trunks have been peeled, their gnarled, central and cylindrical cores are used to obtain different sub-products, including strips for the sheets (blocks) and packaging the laminated wood panel boards obtained, pallets, or chips for use as fuel for steam generation.” The fixing points are then positioned so that when the trunk is placed on the lathe’s rotation points, it is fully prepared for peeling. The XY loader is fitted with several laser sensors that recognize the shape of each trunk and rotate them 360° on the fixing points. Squared trunks from the tipping saws are accumulated collection tables and raised by a step feeder that transports trunks to a lathe XY loader. The resulting timber produced from roll cutting is shredded in chippers and taken to the wood waste deposit for use as a solid fuel for steam and electrical energy generation.Īny trunks that fail to meet the production process requirements can be chipped later and turned into fuel or ultimately rejected and returned to the supplier. This operation is performed by two production lines, each fitted with 3 circular saws. The rolls are removed from the maceration vaults and fed into a saw cutting system to obtain uniform logs (2.63 meters each) called trunks. The same time, in a cascade system, until reaching the chamber floor, sloped The warm water sprinkled over the rolls heats them up and falls between them at The purpose of this operation is to soften the roll fibers and make For such purpose, the excess maceration process water is sent byĭebarked rolls are placed in vaulted chambers in parallel lines for conditioning meant to soften the roll fibers for subsequent processing. The objective is to minimize well water use to restore The roll moistening system is comprised of a water pool for sprinkling, pumps and a pipe While the rolls are being stowed before debarking, they are kept moist using a sprinkler or spray system to prevent the appearance of cracks in eucalyptus trunks and spots on pine trunks. Once there, the rolls are unloaded, transported andĭeposited using Caterpillar loaders, classified by species, length and arrival date at Upon arrival at the plant, trucks are weighed and moved to the raw material receptionĪnd temporary storage zone. In both cases, the average net unit load is 28 tons of wood equal to around 30 m³ The eucalyptus or pine rolls for industrial production are transported from the forest plantations to the plant using 6-axle trucks or, instead, truck/trailerĬombinations, coupled with 5-axles in total, both fitted with railings and a gross unit Transport, reception and storage of rolls for industrial production Percentage are sold for cellulose and biomass.
The majority are used for the panel board and solid wood industry, and a smaller In Uruguay, the first commercial thinning is done at 11 or 12 years, both for pine Thinning is used to maximize individual growth along with pruning to obtain quality wood.
Soil tilling, ant control and weedĬontrol are carried out. The land is prepared and conditioned in advance. The forest planting stage begins when the “seedlings” arrive from the nursery, ready to be planted in the field.
