as the rolling section 2 for the stretching and doubling of the fiber bands 3 these said bands are withdrawn from the supply container 31 and run over a lay out table 32 of the spinning machine and guided to the rolling section 2 after the fiber band 3 has left the rolling section 2 it is conducted over the calender rolls 29 into a repository tube 290 which is a component of a coiler plate which places the fiber band in a discharge receptacle 33 the rolling section 2 is isolated from the ambient room space by an enclosure 12 which is shown in dotted lines in fig1 the enclosure 12 contains particularly a produced vacuum which carries away the dust like material which is released by the stretching the enclosure can be swung away from the rolling section wherein this swinging away can be effected in the same direction as the pressure arms the lower rolls of the rolling section 2 are conventionally turned by belt drive fig2 shows the rolling section 2 of the spinning machine of fig1 as is evident from fig1 the fiber band 3 is introduced into the rolling section from the left side of the drawing where it is seized between the section rolls and is stretched by means of different rpm 39 s of various pairs of rolls the rolling section of fig2 is comprised of the entry cylinders 21 the middle cylinders 22 and the exit cylinders 23 the lower roll 230 of the exit cylinder 23 operates in conjunction with a turn around roll 24 the purpose of this reverse roll 24 is to direct the stretched fiber band to the calender rolls 29 stretching of the fiber band does not as.
