ALA, Italy—Tyre Retreading Machinery s.r.l. claims its Black Swan cushion gum extruder system can help retreaders cut labor- and materials-related costs.
The Black Swan system uses a fully automated working cycle that reduces the need for human intervention, making it accessible to less skilled operators at lower training costs, according to a TRM news release. Operator interaction is limited to the loading and unloading of the casing.
The system's integrated profile scanner guides the cushion gum strip application only where its required, providing a material savings of up to about 5 ounces per tire, TRM said.
Compared to the traditional system, the Black Swan material provides high quality application of fresh material with higher bonding, and labor savings without precutting and management of calendered rolls. The use of a rubber compound strip can also can help reduce costs when compared to the use of calendered rolls cut at width.
Additional material savings costs come from the elimination of cementing spray, about 9 ounces for casing, and the lack of material scrap due to aging.
The system is in full compliance with environmental laws avoiding the use of cementing spray, TRM said.
Combining Black Swan with TRM's proprietary Twins technology allows the application of cushion gum during the casing application of the precured tread. TRM claims that the combination maximizes cost savings, reduces process time and improves the quality of bonding between the components. A division of Marangoni Meccanica S.p.A., Ala-based TRM manufactures machinery designed especially for retreaders.
