ABSTRACT:
The running length of an inner synthetic resin within an outer synthetic resin in a composite synthetic resin is reduced by flowing a forced synthetic resin flow behind intermittent flows of the inner synthetic resin. The forced synthetic resin is of the same type as the outer synthetic resin. The composite resin flowing out of the apparatus is cut with a heated wire.
