An engineered wood based siding, cladding or panel with a microstrand interface layer (MIL) applied to the top of the main strand matrix layers to minimize telegraphing, add rigidity and strength, and provide an improved surface appearance. The MIL comprises microstrands applied to the surface of the strand matrix or mat during production, prior to deposition of a fines layer. The MIL prevents the loss of fines into the strand matrix, and helps prevent or eliminate strand telegraphing.

A heating system is provided having a plurality of heated zones, with at least a first zone and a second zone. The first zone receives variable input moisture fiberglass over a first conveyor system and comprises a first compression system above the first conveyor system. Each zone has a fire box at the top and an exhaust stack. Heated air is up drafted through the bottom of the first zone, where the heated air flows from the bottom through the conveyor belt, through the fiberglass media, through the tensioned compression chain, and out the exhaust stack of the first zone. The first zone establishes fiberglass loft, with the second zone providing cure of the fiberglass.
摘要:
The present disclosure includes systems and methods for manufacturing a composite wood product. In some embodiments, the method includes the steps of forming a mat from a plurality of wood elements and an adhesive, the mat having a width W measured substantially perpendicular to a longitudinal axis of the mat and an initial thickness T1. The mat is then moved in a machine direction, the machine direction being substantially parallel to the longitudinal axis and the temperature across the width W of the mat is adjusted. The mat is then compressed into a billet having a final thickness T2. In some embodiments, the system includes a continuous movement mechanism, a side preheat assembly, and a press assembly.
摘要:
A double belt press having a first, lower circulating plastic belt and a second, upper circulating plastic belt. The plastic belts have a first, low flexural strength, and a product gap is formed between facing strands of the plastic belts for forming a plate-like product. A first circulating lower steel belt and a second circulating upper steel belt are provided and have a second flexural strength which is high in comparison to the flexural strength of the plastic belts. A forming section is formed between the facing strands of the steel belts, which forms part of the product gap. The first, lower steel belt runs parallel and bears against a rear face of the first plastic belt in the forming section during operation, and the second upper steel belt runs parallel and bears against a rear face of the second plastic belt in the forming section during operation.

The invention relates to a method of pressing pressing-material mats during the production of wood-material panels in a continuous press, wherein the continuous press has upper and lower heating plates, upper and lower entry plates, which project on the entry side and form an entry mouth, and, in the upper and lower parts of the press, endlessly circulating steel pressing belts which, with the interposition of rolling bars, are supported on the entry plates and the heating plates, wherein the height h0 of the entry gap and, possibly, the entry contour of the entry mouth are set, and wherein a pressing-material mat, which is produced, and possibly pretreated, in a spreading station arranged upstream of the press, is introduced into the continuous press and pressed therein. This method is characterized in that the entry-gap height is checked, set and/or regulated in dependence on the density and/or the weight per unit area of the pressing-material mat.
摘要:
The invention relates to a method for preheating a pressed material mat (14) spread on an endlessly and continuously circulating molding band (6) during manufacture of wood material boards, wherein microwaves from one or both press surface sides are beamed into the pressed material mat (14) to preheat the pressed material mat (14) and the pressed material mat (14) is compacted and hardened by application of pressure and heat after transfer to a continuously operating press (1). The invention consists of microwaves in a frequency range of 2400-2500 MHz being used to heat the pressed material mat (14), wherein the microwaves for each press surface side are generated from 20 to 300 microwave generators (26) with magnetrons (20) of a respective output of 3 to 50 kW. A device for preheating pressed material mats (14) is also provided, in which 20 to 300 microwave generators (26) with magnetrons (20) with an output of 3 to 50 kW and with a frequency range of 2400-2500 MHz are arranged in a conveyor furnace (4) per area side.
摘要:
A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, and upper and lower press belts having confronting lower and upper stretches defining a press gap extending in a horizontal and longitudinal transport direction and respectively running below and above the upper and lower press plates. Upper and lower flexible intake plates are juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and define therewith a downstream portion of an intake mouth flaring upstream. Upper and lower rollers are respectively braced against the upper and lower stretches of the belts at an upstream portion of the intake mouth immediately upstream of the downstream portion of the intake mouth. Further actuators connected to the rollers set a shape of the upstream portion of the intake mouth.
