<p>PURPOSE: To cause extrudate to bend without substantially changing a cross sectional shape of the extrudate by not changing a thickness of a passage but changing a length of a flow passage. CONSTITUTION: Opposed ends of an opening 21 in a die 15 such as, for example, passways P, P1 in which an extrudate 26 moves toward sides 30, 31 via a flow channel 21 and the die 15 to bend when the extrudate 26 moves out of the channel 21 and the die 15 are sufficiently changed in its length. For example, the passways P, P1 to the side 31 opened with an opening 32 in the die 15 are substantially equal, and hence the extrudate 26 passes linearly or in a horizontal plate from the die 15 when the die 12 is horizontal. 15 degrees sufficient to bend the extrudate in a direction of a longer passway B and in a separate direction from short P1, and the same length of the passway P1 at the time of rotting the socket 13 from the horizontal upward is different.</p> |
