Abstract (en)
[origin: EP0485824A2] What is described is a heating device which is used especially in the spinning shaft during the production of partially, highly or completely oriented spun filaments. The heating device is characterised in that its interior cross-sectional surface decreases continuously at least in the lower part. By means of the spinning process carried out with the use of this heating device, filaments of high uniformity can be obtained. <IMAGE>
