Wood veneer roller glue spreader

Types of Wood Veneer Roller Glue Spreaders

A glue spreader for wood veneer comes in multiple types to cater to various veneer applications. The following types of the wood veneer glue spreader are the most popular across the veneer-spreading industry.

• The Roller Glue Spreader: This classic glue spreader works by spreading glue equally on the veneer of wood surfaces. The machine usually features a cylindrical metal roller with glue-applied rollers. Operators place the veneer on the glue-coated roller to achieve even adhesive application. Roller spreaders work best with smaller wood pieces like edging or laminated boards. Also, they excel when using specific adhesive types, such as PVA or contact cement. The advantage of using roller glue spreaders is that they reduce glue waste and drying times.
• The spray adhesive spreader: This wood veneer spreader uses a spray can to suspend adhesives or atomized adhesives directly onto the surface of a substrate or veneer. It can be either a manual trigger-controlled unit or an automatic model that utilizes spray nozzles. The automatic version is often utilized in high-production situations where the requirement for glue is limited, and the need for fast production is high. Spray veneer spreaders tend to be less wasteful and more efficient than the roller type. This is because they apply thin layers of glue. Users can achieve a blemish-free surface when using this spreader type.
• The airless adhesive spray (air-assisted spray): It is a modern alternative to roller coating applications. It employs the use of an airless spray pump that creates a fine mist of adhesive. This mist applies a consistent layer of glue when the adhesive is sprayed from a gun fitted with a dedicated spray tip. The tip changes the adhesive into a spray pattern of varying sizes that is adjustable to suit the application needs. This spreader works excellently for large areas or irregular shapes. It is recommended for use when handling water-based or solvent-based adhesives.
• The roller conveyor spreader: This type of machine uses one or two rollers for gluing. The workpiece is placed on a conveyor belt and passed over a glue-coated roller, ensuring consistent and efficient glue application. The spreader can be operated manually or automatically, depending on the specific model used. While this roller offers flexibility and time-saving solutions, it can sometimes be less accurate than other spreading methods. To achieve optimal results when using the roller conveyor, operators should ensure that the glue application is set to the right thickness.

Scenarios of wood veneer roller glue spreaders

Spreaders are used many times to apply adhesives to veneered components. They are commonly used in the plywood, particle board, and MDF industries. Therefore, consistent adhesive application results in lower glue consumption, higher production rates, and less time spent on post-processing.

Roller spreaders are used to glue solid wood to core material edging and combining techniques in cabinetry, furniture making, and custom architectural millwork. They are frequently used in conjunction with hot melt glue for hot glue roll timing systems where the hot glue is applied to the substrate using the roller spreader, but other adhesives can also be used.

Roller spreaders efficiently apply adhesive for veneering operations and are highly useful when doing multiple veneers with various surface coverings. They also provide a uniform adhesive application for other veneering operations where uneven surfaces may be present. This includes plywood, MDF, particleboard, fiberboard, and blockboard.

Glue spreaders may also be used in assorted woodworking and carpentry projects where other adhesive applications may be required. This includes the decorative surfacing of laminate veneers where large-scale projects are at hand. They are highly applicable in working with plywood, faux wood, and other veneering surfaces where solid wood's appearance and laminate's durability are required. Another primary use includes edge banding applications where spreaders may be used to apply adhesive to the raw edges of boards or substrates before applying laminate or veneer.

Overall, roller spreaders offer an efficient and economical solution for applying adhesive over large areas and veneers. It is always recommended to read the manufacturer's instructions and safety precautions before using any glue spreader or adhesive.
