Special application of the Speedwell Sleeve project to manufacture a spreading pressure roller in aluminum with a high thickness chromium layer for solvent based adhesives with the typical advantages of the sleeve system (easy job change and easy handling). Rossini has studied a special base tapered sleeve in fiber glass to guarantee the dimensional stability to the following step of the aluminum tube assembly and to the final electro-plating coating.
All the special Rossini conpounds are available both in Speedwell Sleeve configuration and Rubber roller.
Tapered base fibreglass sleeve (patent Speedwell system) assembled with a special aluminum tube. Coating of hard chrome high thickness.
