Abstract

Przedmiotem zgłoszenia jest sposób nagrzewania preform z PET w procesie wytwarzania pojemników, zwłaszcza butelek, w którym preformy nagrzewa się za pomocą promieniowania podczerwonego emitowanego oraz odbitego od reflektora usytuowanego naprzeciw emitera, przy czym preformy umieszczone pomiędzy emiterem a reflektorem przemieszcza się wzdłuż emitera oraz obraca wokół ich własnej osi. Sposób ten charakteryzuje się tym, że promieniowanie podczerwone odbite od reflektora skupia się w szereg wiązek następujących po sobie wzdłuż emitera, przy czym prędkość przemieszczania preform wzdłuż emitera w obszarze skupionych wiązek jest mniejsza niż prędkość w pozostałym obszarze promieniowania odbitego. Zgłoszenie obejmuje również piec do nagrzewania preform zaopatrzony jest w reflektor (4) z wyprofilowaną powierzchnią w postaci następujących po sobie poprzecznych cylindrycznych wgłębień (5) rozmieszczonych wzdłuż tunelu (1).The subject of the application is a method of heating PET preforms in the process of producing containers, especially bottles, in which the preforms are heated by means of infrared radiation emitted and reflected from a reflector located opposite the emitter, the preforms placed between the emitter and the reflector moving along the emitter and rotating around them its own axis. The method is characterized in that the infrared radiation reflected from the reflector is focused into a series of beams following each other along the emitter, the speed of the preforms moving along the emitter in the area of focused beams being slower than that in the rest of the reflected radiation. The application also covers a preform heating furnace provided with a reflector (4) with a profiled surface in the form of successive transverse cylindrical recesses (5) arranged along the tunnel (1).
