(KO) PET 발포시트 제조장치 및 제조방법
Abstract
(EN)
The present invention provides an apparatus for manufacturing a foam sheet, comprising: a hopper for feeding foam sheet raw materials; an extruder in which the foam sheet raw materials fed into the hopper are melted and which comprises a die from which a foam sheet is extruded; a cooling device for cooling the foam sheet extruded from the extruder; a first roller part comprising a first upper roller and a first lower roller which are arranged on the upper and lower sides of the foam sheet so as to press the foam sheet having passed through the cooling device; a second roller part comprising a second upper roller and a second lower roller in order to elongate the foam sheet pressed by the first roller part; and a heater part arranged between the first and second roller parts and for heating the foam sheet.
