MANUFACTURING DEVICE FOR CONTINUOUS MOLDED LAWN

摘要

PURPOSE:To provide a device for manufacturing a continuous molded lawn having a structure which is hardly influenced by heat shrinkage in the continuous direction when it occurs and can maintain the surface stability in an installed state regardless of change of the peripheral temperature. CONSTITUTION:An auxiliary molding roll 3 is arranged at a position downstream of resin injection to a molding drum 1. The auxiliary molding roll 3 has, on its outer peripheral face 3a, a plurality of flat tooth-shaped protrusions 31 which can be fitted into a base body molding groove 11 of the molding drum 1 so as to form a clearance with respect to the bottom face of the groove at a predetermined pitch along the peripheral direction of the roll. Recesses are formed at a constant pitch on a rear face of a base body of a molded lawn by the auxiliary molding roll 3.
