| description | A die attached to a cylinder of an extruder includes: an inflow port for supplying a molten resin from the cylinder; a plurality of hole portions for discharging a strand made of the molten resin; a resin flow path portion 22 extending in a flow path direction that leads to the plurality of hole portions from the inflow port; and a plate member 11 movable in an up-and-down direction so as to protrude toward the resin flow path portion 22. The plate member 11 is arranged along an X direction, and both end portions of the plate member 11 in the X direction move in an up-and-down direction so as to contact with an inner wall of the resin flow path portion 22. A protrusion amount t1 of the plate member 11 into the resin flow path portion 22 becomes small from a central portion in the X direction toward both end portions. |
