A method and equipment for forming a composite synthetic resin material

摘要

The length of an inner synthetic resin (116) within an outer synthetic resin (114) in a composite synthetic resin is reduced by forcing a forced synthetic resin (120) flow behind intermittent flows of the inner synthetic resin, The synthetic resin in the forced resin (120) flow is of the same type as the outer synthetic resin. The composite resin flowing out of the apparatus is cut with a heated wire.
