Abstract
PURPOSE: To obtain a single lace pattern material having beautifyl profile, by shaping the wedge like concave streak along the profile line of the lace pattern by using the forming roll having the convex streak of sharp ridgeline and separating the pattern perfectly.
CONSTITUTION: The concavity mold 6 of the desired lace pattern is engraved on the peripheral face of the forming roll 3, and in the concave groove 7 located along the profile line, the convex streak 8 of sharp ridgeline is protruded so as the slight clearance is maintained to the standard surface level of the forming roll 3. The forming roll 3 is heated at the predetermined temperature from the inside by circulating heating oil through the double hollow shaft 9, and the resin melt extruded from the extruder 1 is filled into the concavity mold 6. The concave streak is shaped in the profile line 11 by the convex streak, and the lace pattern material L torn and separated readily by the concave streak 12 is obtained continuously.
