Abstract
A spinning machine for the doubling or stretching of fiber bands with a rolling section having lower rolls which are secured in journal blocks, and wherein the upper rolls may be also secured on said journal blocks with pressure means for the loading of said upper rolls, it is proposed that the pivoting axis of the pressure arm for the placement of the pressure means to the upper rolls be arranged in such a way that, when observed in the running direction of the fiber band, said axis lies behind the rolling section. Advantageously, what is achieved thereby, is that the spinning machine can be maintained in a considerably simpler and quicker manner. Following the upward pivoting of the pressure arm, the entire area of the rolling section becomes freely accessible. The pivoting geometry of the pressure arm can be so varied, that the upper rolls can be easily restored into the guides on the journal blocks of the lower rolls.
