Abstract

PURPOSE:To prepare a thermoshrinking tube with an embossed pattern hard to vanish even thermoshrinkage by after coolsolidifying the tube, printing an embossed pattern on its external surface and spreading it at a temperature under extruding pressure and above the secondary transition point. CONSTITUTION:A tube 3 which has been fused extruded from a ring cap 2 connected with an extruder is once cool solidified in a cooling water tank. Subsequently, keeping the surface temperature of the tube 3 under the melting point of the tube and above the secondary transition point, the tube 3 is pressed in a pair of emboss rolls having on its surface an embossed pattern and turning in the direction of the arrow A to perform an embossing process on the surface of the tube 3. Further it is extended in the extending part B at the temperature under pressing and above the secondary transition point to be taken over through a pair of nip rolls.
