After continuous usage, it is quite often rollers are worn out on bearing journals and damaged on keyways and threads. Some shafts can be snapped off after excessive force and imbalance.

LASERLIFE LITTLEJOHN offers customers comprehensive corrective engineering to salvage damaged and worn-out rollers: The service includes:

• Repairing bearing journals, threads and keyway journals
• Replacing broken shafts
• Straightening bent journals
• Dynamically balance rollers to customer specified RPM
• Repairing internal bores
• For rollers used in an extreme corrosion environment, build-up roller bases with a stainless steel layer to prevent corrosion on coatings

The corrective engineering jobs are carried out by methods of welding, hard-chrome plating, machining, grinding and dynamical balancing etc. They are done both in house and out sources to guarantee high quality standard and customer satisfaction.

For many years, LASERLIFE LITTLEJOHN have manufactured new roller bases for all type of machines.We manufacture new bases for narrow and wide web as well as corrugated and offset machines.

We are able to either visit on site to measure up the existing roll bases or measure in house at our facility. We then produce an Autocad drawing which the customer approves before commencement. We also have many hundred drawings on file. It is crucial that we use the best possible but affordable metals to ensure the roller will last for many years. We always stress relieve the barrel and journal than machine to required surface finishes.

It is quite common that anilox cells become clogged up with dried inks. Laserlife Littlejohn offers customers three different anilox cleaning method to reclaim anilox volume, therefore to improve printing quality.

Sodium Bicarbonate blasting
This is the more conventionally used method. The Sodium Bicarbonate is blasted on the roller surface through a low pressure nozzle. The soda media will break down the ink in the cells without damage to the cell walls.
Usually the method is quick and efficient, except for some tough varnish and inks which need different cleaning methods.

Ultrasound Cleaning System
The anilox roller will be half submerged in the solvent detergent tank of an ultrasound cleaning system.. The ultrasound will agitate the solvent, creating micro-bubbles to attack on inks inside the dirty cells. The use of dual-frequency ultrasound will dramatically reduce the possible damages from ultrasound.
This method is ideal for regular on-site cleaning.

Laser Cleaning
For some tough inks and varnish, the above cleaning methods will not work, then a laser cleaning will be more effective.
The inks and varnish will be burnt in a de-focused laser beam which is tuned to burn out the residues in the cells without damage to any cell structure.
This method is only applied when normal cleaning is not effective because of the higher cost.

LASERLIFE LITTLEJOHN have the facilities to clean your anilox roller. We inspect the roller in house, checking general condition; tir and bearing journals. The roller is then cleaned by one of our many cleaning methods. On completion we supply a report that includes the actual measurements of the anilox screen together with a general condition of the roller. We are able to clean your anilox overnight if required.
