Provided are apparatus and method of dispensing an adhesive liquid for a dust trap, in which the adhesive liquid is dispensed to a camera module while effectively cleaning the adhesive liquid that may be smeared on a nozzle, thereby enhancing productivity and quality of a process of forming a dust trap.

Described herein is an apparatus for dynamic metering of sealant volumes, and also described herein is a corresponding method.

The apparatus of the invention includes two containers for sealant components; a first drive, which is connected to two devices, each of which is able to convey one of the sealant components from its container; a drive controller; a mixing unit for mixing the sealant components conveyed from the containers, having an opening for applying the sealant to a component; and also, additionally, a compensating container with a compensating volume; and a second drive, which is connected to a piston which reaches into the compensating volume of the compensating container.

The compensating container in this arrangement is connected to the mixing unit. The first drive and the second drive can be dynamically controlled jointly by the drive controller.

A coating method of repeatedly forming a lower surface coated portion obtained by forming a coating film on a lower surface of a base material and a lower surface uncoated portion obtained by exposing the lower surface of the base material between a terminal end of a lower surface coated portion and a starting end of the lower surface coated portion, by switching on/off in supply of a coating liquid to a slit die facing the lower surface of the base material through a discharge port while the base material is transferred, in which a distance between the lower surface of the base material and the discharge port of the slit die is temporarily expanded beyond a distance so far by a base material height changing device during a specific period from termination of the supply of the coating liquid to the slit die to restarting of the supply is provided. Accordingly, a gap between the base material and the slit die can be maintained contrary to an operation in which the base material is drawn into the coating liquid at a terminal end of the lower surface coated portion. Further, the shape of the coating film at the terminal end of the lower surface coated portion is improved and linearity of the terminal end of the lower surface coated portion is improved.

An electrode plate manufacturing apparatus includes a first coating device configured to apply a first active material coating on a first side of a current collector; a perforating device configured to perforate the current collector from a second side of the current collector, the second side being opposite to the first side; and a second coating device configured to apply a second active material coating on the second side of the current collector, where the perforating device is located downstream of the first coating device along a travel path of the current collector, and the second coating device is located downstream of the perforating device along the travel path of the current collector.

A method of and system for producing Class-A fire-protected truss structures constructed from: a plurality of lumber pieces dip-coated with clean fire inhibiting chemical (CFIC) liquid to form a plurality of Class-A fire-protected lumber pieces; and a set of heat-resistant chemical-coated metal truss connector plates for connecting together the plurality of Class-A fire-protected lumber pieces to form a Class-A fire-protected truss structure. The improved Class-A fire-protected truss structures can be used in constructing safer roofing and/or flooring systems in wood-framed buildings, having improved fire performance characteristics.

An automated lumber fabrication factory supporting an automated process for continuously fabricating cross-laminated timber (CLT) products that are automatically dip-coated in a reservoir of clean fire inhibiting chemical (CFIC) liquid, so as to produce Class-A fire-protected CLT products in a highly automated matter.

In a lumber factory, an automated laminated veneer lumber (LVL) process supported by a lumber production line employing a cross-cutting and rip-sawing stage, a dip-coating stage, a spray-coating stage, a print-marking stage, and a stacking, packaging and wrapping stage. At the dip-coating stage, cross-cut and rip-sawed LVL product is automatically transported and submerged through a dipping reservoir containing clean fire inhibiting chemical (CFIC) liquid, and then wet-stacked and set aside to dry. Once dried, the dip-coated LVL products are returned to the production line and sprayed coated with a moisture, fire and UV protective coating at the spray-coating stage, and then passed through a drying tunnel for quick drying of the spray-coating to produce Class-A fire-protected LVL products. The Class-A fire-protected LVL products are stacked, packaged and wrapped at the stacking, packaging and wrapping stage into a package of Class-A fire-protected LVL products, ready for shipping.

A method of producing packaged bundles of Class-A fire-protected lumber for use in wood-framed building construction. The method involved maintaining a dipping tank in a lumber factory, containing a water-based clean fire inhibiting chemical (CFPC) liquid at a depth sufficient to cover pieces of raw lumber while being treated during dip-coating operations. Untreated lumber pieces are submerged into the dipping tank, piece by piece, in an automated manner to coat all surfaces of the lumber pieces in CFIC liquid, and then removed from the dipping tank to produce pieces of Class-A fire-protected lumber having a CFIC liquid coating. The Class-A fire-protected lumber pieces are automatically wet stacked, packaged and wrapped into a packaged bundle, and allowed to dry.
