Davis-Standard says feed roller reduces scrap

Pawcatuck, Connecticut - Davis-Standard, LLC says a new feed roller design can help reduce the leakage and scrap created during elastomeric extrusion processes.

Known as the ELF (Elastomer Leakage Free) system, the invention was patented earlier this year by Davis-Standard engineers John Radovich and Jeffrey Bryan. The company says the ELF provides effective feedback of overflow material and can be retrofitted to existing extruders to provide cost savings.

According to Radovich, “This development was market driven. Customers did not want the cost of lost product or scrap from feed roll leakage. The maintenance associated with feed roll bearing failures and the clean-up of rubber leakage were also issues. Our patented roll housing and roll end seal design address those problems.”
