A Black Bros. machine is a superior machine made with quality components. When it comes to servicing your machine, make sure you only use OEM parts and manufacturer-certified service.

Here are a few reasons to entrust the care of your machine to the experts:

BLACK BROS. ROLL COVERING & ROLL GRINDING SERVICES

As an OEM manufacturer, we take pride in bringing the best to your doorstep. Using Black Bros. for your roll reconditioning services will save you money by making the grinding of your rolls the primary goal before spending the extra money on roll covering.

  • A Black Bros. roll will typically yield 2 or more regrinds before recovering is needed
  • Every roll receives an inspection of the bearing journal surface to keep them running within factory tolerance
  • Black Bros. keeps your machine at OEM standards by maintaining a running history of all the roll work done to each individual roll

WE AIM TO OPTIMIZE YOUR ROLL COATER’S PERFORMANCE

Proper alignment of your machine’s end seals to the roll flange make for a clean operation. However, improper alignment of the end seals to the roll flange can cause a loss of coating material due to leaking. If the end seals are worn or distorted, the flange worn or misaligned, or the rolls were improperly installed, you can end up losing coating material. Daily loss of coating material can result in annual losses that rival the cost of manpower, especially with multiple machines. Allow Black Bros. to help maintain your rolls to their original specification. We highly recommend you send in both the coating and doctor rolls (the paired set) to have them machined to exact roll face length.

HIGH STANDARDS MANUFACTURING OF OEM ROLLS

The following are calculations of waste material based on normal production in a mid to high-volume manufacturing environment:

  • 5 gallons / day of PUR = $48,730.00 / year
  • 5 gallons / day of LMC = $36,150.00 / year
  • 5 gallons / day of PVA = $13,400.00 / year

HIGH STANDARDS MANUFACTURING OF OEM ROLLS

As a machinery manufacturer, Black Bros. knows the performance and function of your machine from the inside out. High quality standards are mandatory here. The same care and exacting standards that go into each newly-manufactured roll also go into the reconditioning of that same roll to guarantee decades of use.

It starts with high quality goods; from raw steel to a finished roll. Black Bros. accurately assembles and machines each roll through a series of carefully automated operations. A typical roll will go through these standard processes:

  • Initial machining of raw, heavy walled steel pipe
  • Fitting and automated welding of end plug assemblies
  • Precision machining of roll body, flange, shaft & journals
  • Wrapping of roll core with rubber composite material(s)
  • Sequenced bake/cure in pressurized Autoclave furnace
  • Grinding & grooving of roll to customer specification

Black Bros. is a vertically-integrated manufacturing facility, providing in-house services for the complete process of roll machining and rubber vulcanization. All Black Bros. machines are maintained to operate at peak performance. So whether you’re buying a new machine, a new set of rolls, or using Black Bros. for your roll reconditioning services, you are sure to get the FULL VALUE out of a machine that is built to endure!

What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
