PROBLEM TO BE SOLVED: To provide a profile extrusion molding apparatus having an increased molding speed and capable of achieving cost reduction and space saving in spite of simple constitution such that a take-over machine is dispensed with and a die 2 is made small as a whole. SOLUTION: The profile extrusion molding apparatus is equipped with an extruder 1, the die 2 provided at the leading end of the extruder 1 and the cooling former 7 provided at the leading end of the die 2 and having length within a predetermined range. The cooling former 7 cools the part having a predetermined range of length from the outlet of the cooling former 7 of the resin guided from the die 2 after plasticized by the extruder 1. By this constitution, a sudden temperature gradient is applied to the interior of the cooling former 7. |
