<p><P>PROBLEM TO BE SOLVED: To provide an extruder cap that can prevent break of a side portion of a rubber strip by uniformizing density in a width direction of the extruded rubber strip, and to provide an extruder device using the same. <P>SOLUTION: The extruder cap 1 is attached to an end portion of the extruder device via a head, and a rubber material extruded from the extruder device is formed in the rubber strip having a predetermined cross section shape. A narrowed region that reduces the height of a flow path 2 in comparison with both sides in a width direction is provided in an intermediate region in the width direction of the flow path 2 of the rubber material in a cross section surface intersecting a flow direction of the rubber material in the extruder cap 1. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
