How does the reblading of Fleshing and Shaving cylinders work?

Renlaw has taken over the reblading and caulking of cylinders from IMK. Operations are to be moved to our main factory in Cape Town in November 2023. We are pleased to have had the opportunity to have our staff trained by the original IMK reblading technicians, who are now also retiring (40 years is a long time!). 

While it is no secret that the blades themselves are imported from the UK, this is not a game just any blade manufacturer can step into. 

The reblading process requires technical precision and an integral understanding of the industries in which the cylinders are used.

Most commonly, this includes leather working, tanneries and game skins. These cylindrical blades need to have the strength to do their job, while not causing any damage to the skin or leather.


Replacing Fleshing and Shaving blades:

When the shaving cylinder arrives at the factory a thorough inspection is performed to ensure that there are no abnormalities in your cylinder.

The cylinder is secured to allow safe removal of the worn blades. The spiral blade is carefully taken up and out of the groove in a continuous spiral motion to lift the blade without damaging the groove walls. Once the blade is removed from the groove, the caulking is extracted using purpose-built grips.

The cylinder is then prepared for reblading. It must be thoroughly inspected and cleaned.

We generally make use of Hardy blades which are imported from the UK. Hardy shaving and fleshing blades are engineered so that the portion fitted into the cylinder groove is slightly ‘softer’ than the rest of the blade to allow for safe re-blading without compromising on performance.

Blades which are harder at the setting edge have a tendency to fracture.

The new spiral blades are then fitted.

We use copper caulking to secure the blades rather than steel or any other material. Copper holds the blade best and cause no damage to the cylinder during the de-blading and re-blading process.
