Industry: ENGINEERED FLOORING
A Complete System from Union Tool: Hot Melt Roller Coater, Lay-Up Conveyor and a Multi-Nip Rotary Laminator
Engineered flooring is used as an alternative to hardwood flooring. The hot melt roller coater applies a controlled and consistent amount of (PUR) adhesive. The lay-up conveyor allows a piece of lamella to be placed on top of the coated core. The multi-nip roll machine is then used for pressing and holding the two pieces together.
Here are a few examples that illustrate ENGINEERED FLOORING in action:
ENGINEERED FLOORING SYSTEM - A complete material handling and coating system for laminating engineered flooring. This engineered flooring system includes a hot melt roller coater, lay-up conveyor and multi-nip roll machine. The hot melt roller coater coats plywood with adhesive and the lay-up conveyor allows a piece of veneer to be placed on top of the coated plywood. These multi-nip roll wood laminating machines are then used for pressing the two pieces together. Engineered flooring is used as an alternative to hardwood flooring.
MULTI NIP ROTARY LAMINATOR - Union Tool has designed a Multi-Nip Rotary Laminator for Engineered Flooring that combines high pressure rolls with hold down rolls to insure proper bonding of Laminated Flooring.The second picture shows a Nine (9) Nip Machine that incorporates high pressure nip points at the entry and exit nip points. The high pressure nip points use 6.5” diameter rolls with the top rolls adjustable in relationship to the bottom rolls from 0 to 3”. Each nip point at the exit and entry end of the machine utilizes two (2) 6” diameter air cylinders attached to the top roll to provide the pressure. The middle section of the machine incorporates 4” diameter hold down rolls. The top hold down rolls are also adjustable in relationship to the bottom rolls and use two 6” diameter air cylinders to raise and lower the top hold down roll section. The hold down section allows the hot melt adhesive to cool down and provide necessary green strength for the next production process. This 9 Nip Rotary Laminator can laminate at speeds up to 100 feet per minute.
HOT MELT ROLLER COATER, Series #15, Model A (PB20616) - Hot Melt Roller Coater designed to apply hot melt coatings such as wax, contact adhesive, PUR adhesive, pressure sensitive adhesive or virtually any coating material that requires heat for roller coater application.
FLYING CUTOFF SAW - The Union Tool Corporation has designed a Flying Cutoff Saw that can be incorporated into our engineered wood flooring lamination system! This saw is manufactured to cut laminated engineered flooring planks as they exit the Union Five Nip Rotary Laminator. The Union Flying Cutoff Saw allows for continuous lamination at speeds up to 50 feet per minute!With incorporating dual sensors, the saw will detect a gap in the top veneer layer that was created by the operator at the layup station placing the veneer onto the coated surface of the core. In a smooth downward motion, the saw will make a cut when each gap is detected.
