Black Bros. Roll Coaters and Adhesive Spreaders - W W Thayer Company

Black Brothers Adhesive Spreaders And Roll Coaters

Established in 1882, Black Bros. has become an international leader in the manufacture of high quality gluing, coating, and laminating equipment. Our exceptional machines are the result of many years of design, engineering, and manufacturing experience, combined with an extensive and ongoing research and development program. Black Bros. testing and research laboratory has always played a key role in the development of advanced machine technology. This facility is also instrumental in evaluating the various materials and methods proposed for the customer's operation prior to the machine order placement. Many equipment and application improvments can be attributed to our close cooperation with customers and material suppliers.

Standard Features

• Easy and efficient clean up - The roll reversing feature of the coaters and spreaders makes them almost self-cleaning with no need to touch the rotating rolls. Step-by-step cleaning instructions appear on a decal at each end of machine
• Heavy frame construction - Heavy welded steel frame construction assures rigid roll alignment for precise coating action and extended coverage rates.
• Machine guarding - Guards at key locations help protect operators and/or cleanup crew from nip points on upper and lower coating and doctor rolls. Electrical interlocks (optional) shut off machine when the guard is pivoted away from protective position.
• Micrometer scale doctor roll adjustment - Convenient handwheel adjusts doctor roll to control coating material thickness for maximum economy and minimum waste. Easy to read scale calibrated in 0.001'' increments to allow exact repeat settings.
• Electrical equipment - All machines are pre-tested and ready to operate, complete with drive motor and electrical controls, including magnetic motor starter, NEMA 12 enclosure with fused disconnect, wired to meet customer's requirements
• Lubrication - Grease fittings for pressure lubrication of bearings and other moving parts to protect against corrosion, dirt, and moisture for long life with minimum maintenance.
• Roll opening indicator - Provides digital readout in 0.001'' increments. Extremely helpful in sealing stock thickness. Also available with metric readout.
• Variable speed drive - For cleaning or to synchronize with other machines in-line. Match machine speed to various production requirements, stock sizes, ETC.
• Single handwheel doctor roll adjustment - provides doctor roll to coating roll adjustment from one end of machine with digital read-out. Ideal for in-line operations.
• Automatic roll clean up system for water soluble materials - With the push of a button, Black Bros. automatic water-wash cleaning system spray-cleans rolls during a preset series of forward/reverse roll rotation cycles.
• Minimum contact outfeed finger assembly - Stcok support roll with mimimum contact wheels assists in off-loading panels from spreaders.
• Air lift on top rolls - When actuated by operating conrol bar or palm button, top roll assembly quickly raises 3'' above bottom roll. Ideal for roll cleanup or when operation is stopped for a period of time. Push button returns top rolls to proper coating position
• Automatic liquid level control - Liquid level sensing unit insures constant coating material level in the coating reservoir. Automatic viscosity control units are also available to maintain proper viscosity of fast evaporating and other critical to control liquids.
  

Model 22-D - The 22-D is a proven, popular model with a reputation for payback, production, efficiency, and profitability. Exceptional accuracy delivers consistent quality, reduces material waste, fewer rejects with maximum production output, and reduces downtime. Single or variable speed ranges (From less than 10 to over 300 FPM) meet most requirements. Full length operating control bars on both sides offer convienient machine control and emergency stops. The 22-D's heavy duty construction means long machine life and low maintenance. Includes time saving, easy adjustment for substrate sizes and coating thickness.

Model 775 - Built for durability and longevity, the series 775 provides a compact and economical approach to adhesive spreading. The efficient design - with fewer components than other models - makes the 775 easy to maintain and increases uptime. This adhesive spreader is a popular choice for companies who need an efficient method of applying adhesive, but cannot justify the larger, higher production adhesive spreaders. Available in three standard sizes: 44'', 56'', 69'' with numerous standard features and options.

775 Hot Melt Spreader - This spreader is built to handle the increasing market demands for a reactive hot melt moisture-cured polyurethane (RHW/PUR) adhesive application. The RHM-775 adhesive spreader is equipped with the necessary features to handle RHM/PUR materials: drive components on one end - heat connections on the opposite end, easy acess to the roll ends for maintenance, easy roll change tempered glass for visibility, and vent or port for vapor control/exhaust. The oil heating unit mounts on the same base as the machine. All controls are wired into the same control box for installation and operating ease. Standard units are available from 32'' through 74'' capacity. In units up to 110'', special arrangements can be designed and manufactured to customer specifications. Bulk melt units and/or arrangements for connection with the hot melt product supply are also available. Bulk melting units and/or arrangements for connecting the hot melt product supply and a liquid level sensing control are also available.

DD-200 Hot Melt Adhesive Spreader - The DD-200 Hot Melt Adhesive Spreader is the latest addition to the Black Bros. Hot melt Spreader family. Featuring many of the advantages of the 775 Hot Melt machine, it is capable of producing extremely smooth and light coating weights. Selected options offer flexibility to apply a wide range of hot melt adhesives and coatings. Roller widths from 44'' to 68'', a compact footprint and an attractive price, the DD-200 is an excellent choice for laminators entering PUR production process for the first time.
