is in thermal connection with the heated external wall of the spinning device and thus strong cooling of the door 1 is advantageously prevented fig2 displays the open door 1 of the reheater 9 of the spinning device of fig1 in cross section the heatable metal body 1 a when the door is open 1 is applied to the spinning device so that a cooling of the door 1 is largely prevented and the reheater 9 is ready for operation immediately after closing the door 1 when the door is open 1 it is relatively easy to install the spinning package 10 in the spinning head 12 the spinning package 10 for this purpose is positioned on the mounting device 11 and is moved through the blowing shaft whose doors 14 are open and through the reheater 9 to the spinning head 12 while the door 1 is open suction removal of the undesirable vaporizable compounds can occur through the essentially horizontally positioned suction duct 1 d now positioned directly below the spinning head 12 fig3 displays two arrangements i ii of two adjacent doors 1 according to fig1 and 2 the first arrangements i shows the door 1 closed the second arrangements ii shows the door 1 open as represented in the first arrangements i the doors 1 have connections with two levers 2 2 u2032 which are parallel.
