There are several options available for supplying adhesives to your Black Bros. Co. machines. This can be as simple as pouring from a ladle or pail, but many customers find that glue supply pumps or overhead gravity feed systems better serve their needs. Black Bros. Customer Service can help you determine what will work best for you.
Leakage sometimes results from over tightening, which can deform the backing plate. Try to think of the seal as a packing material. It should be slightly wet. Some other things to check would be:
- Are the roll ends clean & flush?
- Is the sealing surface flat?
Here are several things to check:
- Incoming voltage - is the voltage consistent with the machine specifications?
- Have the end seals been tightened so much they are acting like a brake and are preventing the roll from turning?
- The electrical interlocks may need adjustments.
To make sure the rolls are parallel horizontally, separate the rolls slightly and use a feeler gauge to check spacing at both ends of roll. Remove locking pin and turn one side or the other of the coupling until feeler gauge "feel" is the same at both ends of the roll. Then replace the locking pin in the adjustment notch that most nearly lines up. Reset dial on roll opening indicator as necessary. To parallel rolls vertically use this same procedure with doctor roll take-ups.
Proper grooving insures consistent quality and performance. A good rule of thumb for a customer operating eight hours per day, five days a week is to re-groove every six to nine months. Other factors which affect this timing include cleanliness and spread pattern. Our Customer Service representatives can assist you in determining when your rolls were last serviced.
There is a simple and accurate method to determine the spread rate:
- Cut a sample of stock exactly one square foot
- Weigh on a gram scale
- Pass through machine and weigh again
- Subtract the first weight from the second
- If stock is coated on both sides, multiply the difference in weight by 1.1 for spread in pounds per thousand square feet. If only one side of the sample is coated, multiply by 2.2
A wet film thickness gauge may be used to determine spread rate on smooth coating applications, or as a comparison to previous method.
The idler assemblies and roll bearings should be checked and lightly lubricated on a weekly basis. It is very important that the roll bearings are not over greased. Heated roll machines require special attention - please call our Customer Service department.
Many Black Bros. Co. machines are equipped with a mechanism that requires the applicator rollers to be separated at least 3" (76 mm) to reverse. Try opening the machines 3.5" (89 mm).
With proper use and cleaning, they could last up to a year. If you experience premature end seal failure contact our Customer Service Department.
Glue must be cleaned off after each use. If the adhesive can't be dissolved by soaking, rolls should be removed and sent in for reconditioning. For water-soluble coatings, an automatic clean-up system is available. Contact our Customer Service Department for more information.
Continuous polyethylene liner material is available from Black Bros. Co. -call Customer Service for more information.
Yes. It is available as an option on new equipment.
This could be caused by:
- The doctor roll clutch is slipping.
- The end seals are adjusted too tightly.
- The doctor roll bearings are frozen.
- The doctor roll clutch has excessive wear.
The clutch can be adjusted while the machine is stopped. Before adjusting, however, make certain rolls are properly aligned. Then rotate the adjusting nut clockwise to increase clutch tension, or counter-clockwise to decrease clutch tension.
Increase "doctor roll to coating roll" pressure for a thinner coating and decrease for a thicker coating. Also, roll groove patterns are design to apply coats within certain thickness ranges, so you may wish to consider changing to a different pattern. Our Customer Service Department can assist you with this.
Standard sizes for Black Bros. Co. equipment start at 26" (660 mm) wide and increase in 6" (152 mm) increments to 100" (2540 mm). Additional sizes or custom lengths are available.
Typically, for a Model 775-- 40-120 fpm, and for a Model 875-- 40-120 fpm. Generally any 3:1 ratio is available within reason.
Yes. Consult a Customer Service representative.
The upper drive roll (smaller roll) is located on the "in feed" side of the applicator roll.
30" (762 mm)
Use a "feeler gauge" to set the separation between rolls. Then loosen the setscrew and reset the dial to the known thickness. Retighten setscrew.
You may be carrying to much coating on the rollers. Or your feed gap is too tight. Try raising the upper roll slightly (.005).
The rolls may not be parallel, or the substrate could be uneven. Prolonged running of smaller pieces can cause uneven roll wear.
Follow the procedures outlined on the cleaning instruction decal will make a big difference in roll life. Also properly adjusting the feed gap. Another consideration is proper groove specification selection for the required application.
Only when working with water-soluble coatings.
Approximately 3,000 lb (1361 kg).
Yes, it's called a liquid level control. It will automatically control a pump and valve to add coating material as required.
The panel cleaner requires 50 CFM's per inch of nominal length. For example: a 68" wide panel cleaner requires 3400 CFMs.
It usually takes 15-20 minutes.

- The electrical interlocks may need adjusting.
To make sure the coating rolls are parallel horizontally on machines with Single Handwheel Doctor Roll Adjustment, separate the rolls slightly and use a feeler gauge to check spacing at both roll ends. If adjustment is required, remove the locking pin from the differential coupling and turn one side or the other of the coupling until spacing is the same at both ends of the roll. Then replace the locking pin in the adjustment notch that most nearly lines up with the new setting. Reset the dial on the roll opening indicator as necessary. To parallel rolls vertically, use this same procedure adjusting the Upper Elevator Shaft on top of the machine.

Use a "feeler gauge" to set the separation between rolls. Then loosen the setscrew and reset the dial to the known thickness. Retighten setscrew.
The rolls may not be parallel, or the substrate could be uneven. Prolonged running of smaller pieces can cause uneven roll wear. Try turning stock 180 Degrees, if your problem moves to the other side your cause is the substrate material.
Follow the procedures outlined on the cleaning instruction decal will make a big difference in roll life. Also properly adjusting the feed gap. Another consideration is proper groove specification selection for the required application.
Substrate temperature could be too low. This condition is especially important in steel processing industries. Thermal shock is the result. The hot adhesive will not adhere to the cold substrate, in some cases where the substrate temperature is acceptable adhesive temperature may be too low.
Depending on application temperature roughly 30-40 minutes.
Clean up of an RHM-PUR Spreader can be performed in approximately 20-30 minutes.
An oil heater and circulating pump allow you to heat rolls to 450 degrees Fahrenheit.
Yes, control valves can be provided to eliminate oil flow to either roll.
Yes, to remove adhesive fumes. The size of machine will determine the size of the exhaust system needed. A port is provided on top of the PUR Spreader to connect to your exhaust system.
If the paper peels off and exhibits no adhesive, your temperature may be too high. Try lowering temperature of the roll or increasing the roll speed. If the paper exhibits adhesive but the board is dry, roll temperature may be too low. Try increasing the heat or reducing the roll speed.
The lifting device included with the TB-60 Hot Roll Laminator is rated not to exceed 1000lbs. The hoist is sufficient for rolls of common papers and foils.
Almost any commercially available paper or foil from 30-gram to K series are successfully laminated with a TB-60.
325-350 degrees would be acceptable for most papers. Operating speed and paper thickness are determining factors in temperature settings.
TB-60 rolls can reach operating temperature in approximately 30 minutes.
All you need is an abrasive free cream hand cleaner such as Goop or Go-Jo. Stop the rolls and with a gloved hand and paper towels you can easily clean the foreign material from the roll. Remember to never touch a moving roll.

The normal stroke length is 5" (127 mm).
Yes. In several sizes and heat ranges.
Count the number of pods in the press. Call that number "N." Determine the gauge pressure, and call that "G." Determine the area of the piece in square inches, and call that "A." The pressure being delivered to the piece is 90 x N x G divided by A.
Most customers report press times that range from 30 to 40 minutes. Contact your adhesive supplier to obtain their recommendations.
Sufficient pressure is needed to bring the glued surfaces into contact. Too little pressure or too much pressure can cause de-lamination. Your core stock will be the determining factor on which Air Pod Pressure setting you will need.
30" (762 mm) - Note: risers can be provided to match the pass line height of your existing equipment.
