Resilient rail support block assembly and manufacturing thereof

Abstract

The invention relates to a method for manufacturing a resilient rail support block assembly to be mounted embedded in a railway substructure. The resilient rail support block assembly comprises a resilient tray member having sandwich type walls with an inner and an outer anchoring sheet, and a moulded block. The resilient tray member is manufactured by positioning the outer anchoring sheet in an injection mould, and injection moulding a monolithic core member of resilient foam material in the injection mould, securing the inner anchoring sheet to the monolithic core member, opposite the outer anchoring sheet, and folding the monolithic core member to form the resilient tray member.
