Abstract (en)
[origin: DE19836682C1] The door (1) structure of an after-heater (9), in the path of melt-spun filaments on leaving the spinneret, has a heated metal body (1a). An insulation (1b) is next to the metal body (1a), with a vertical suction channel (1c) at its outer side opening into a horizontal suction channel (1d) at its lower end. The upper part (1e) of the door is linked to a lever (2) as part of a lever mechanism composed of at least one lever, bearing mounting (3) and a counterweight (4). The upper end (1f) of the suction channel (1c) is linked to a flexible hose (7). The upper part (1e) of the door (1) can be linked to two levers (2), each fitted with a draw spring (6) secured to a further mounting (5). The lower part is linked to at least one further lever (8). The vertical suction channel (1c) has a rectangular cross section flow shape at the transit connection to the horizontal suction channel (1d), with a width and height which decrease continuously over the height of the door (1) into a circular cross section at the upper end (1f). The vertical suction channel (1c) is formed by an outer plate (1g) in a release fitting. The lower horizontal suction channel (1d) is defined by a second lower plate, in a release mounting with a vertical sliding movement.
Abstract (de)
Die Spinnvorrichtung dient dem Erzeugen von Filamenten aus schmelzflüssigem Polymer, welches durch einen Spinnkopf mit Spinndüsen ausgepreßt wird, wobei die Filamente nach unten zunächst durch einen Nacherhitzungsschacht (9) und dann durch einen Blasschacht laufen. Der Nacherhitzungsschacht (9) ist mit einer vertikal bewegbaren Tür (1) versehen, welche einen beheizbaren Metallkörper (1a), eine am Metallkörper angeordnete thermische Isolierung (1b) und einen an der Isolierung außen vertikal angeordneten Absaugkanal (1c) aufweist. Der Absaugkanal geht im unteren Teil in einen nahezu horizontal verlaufenden Absaugkanal (1a) über und ist mit einer Absaugmündung (5) am Nacherhitzungsschacht versehen. <IMAGE>
