A sealant tube for use in a pneumatic sealant gun for reducing or eliminating air bubbles in the sealant being dispensed. The sealant tube may fit within a hollow sleeve of the pneumatic sealant gun and contains sealant and a slidable plunger. The tube body may include an inner surface, an outer surface opposite the inner surface, a first opening, a second opening opposite the first opening, and pressure release openings formed through the tube body, such that air from a pressurized air source flows into the tube body and between the tube body and the hollow sleeve during use of the pneumatic sealant gun, equalizing pressure on the inner surface and the outer surface of the tube body. A seal or gasket may also be located proximate the second opening of the tube body, for forming an airtight seal between the hollow sleeve and the tube body.

High-frequency hot-pressing continuous automatic production lines for dimensional bamboo timbers, and production methods thereof are provided. The production line can include a clip-up store and feeding mechanism fixed with one end of a three-roller type gluing system. An other end of the three-roller type gluing system is fixed with one end of a system for loading, layer up and stacking non-glued bamboo sheets. The outer side edge of the system for loading, layer up and stacking non-glued bamboo sheets is connected to a front inner end of a plate stack conveying system. A high-frequency press and high-frequency generator system is located at a rear inner end of the system for loading, layer up and stacking non-glued bamboo sheets.

A woodworking bridge has two base walls or components that enable the bridge to span an abutment or joint between two work pieces. A top surface enables a clamp to engage the bridge to permit the clamp to apply a clamping force to a first work piece and a second work piece on both sides of the joint and prevent the clamp from contacting the joint. This allows any adhesive that oozes from the joint to be cleaned without curing in the top surface and/or the bottom surface of the two work pieces. The work pieces may then be stained without any cured adhesive in the pores of the work pieces where stain is applied.

A nozzle for applying a fluid material to an object includes a tubular wall with several circumferentially spaced ribs that extend outward from the tubular wall to engage an object to which the fluid material is to be applied. The ribs space the tubular wall from the inner wall to provide a gap for the fluid material and aligning the tubular wall with the hole in the object. The tubular wall provides at least one opening between adjacent pairs of ribs for the fluid material to flow into the gap. A sealing surface on the nozzle engages a portion of the object preventing escape of the fluid from the gap. In a process for using the nozzle, a user manually detects equilibrium between the pressure applied to the fluid in the nozzle and the pressure in the nozzle to determine when the gap has been filled.

A method for manufacturing a folded panel including the following steps: providing a longitudinal recess at the rear side, such that at the front side between remaining panel sections on both sides of the recess a flexible transition section remains, bending the panel sections relative to each other and applying an adhesive in the recess. Before the panel sections are bent relative to each other, a template is inserted into the recess.

A method and system for production of layered wood products employs local and independently operating robotic panel assembly cells including one or more veneer handling robots, one or more core handling robots, and one or more glue application robots to produce stacks of layered wood product panels locally near the pressing stations. Consequently, the stacks of layered wood product panels are independently built at, or near, the location of the pressing stations. This eliminates the need for traditional panel conveyors, traditional layered wood product panel assembly layup lines, and stack press delivery lines. This, in turn, eliminates thousands of moving parts and dozens of people from the layered wood product production process.
