It is only essential that a certain end thickness is not exceeded, which varies depending on the type of fibers fed in, their parallel alignment and the design of the drafting system.

In order to be able to easily insert your hand into the compressor b and between the pair of compressor rollers 21, 31 after opening and closing again, which is expediently done after the drafting system has started up, the upper compression roller is separated from the others on the pressure arm 1 by means of a further loading lever 12 Upper rollers 2 can be attached. To dieaem purpose of the loading lever 12 is brought into the position shown in Figure 6 position before loading of the pressure arm 1 by the tension lever. 11 In this position , the load lever 12, which is pivotable about a bolt 14 attached to the pressure arm, has raised the stop 13 articulated by a bolt 15 , so that the guide arm 16 of the compactor roller 21 is raised. After the drafting system has been loaded and started up, the band S can be inserted unhindered into the Verdiohter and between the pair of compressors 21, 31. The pair of compressor rollers is then loaded by turning the lever 12.

Experience has shown that this introduction of the pandes S and subsequent placement of the compactor roller 21 is necessary, since after the lifting of the upper rollers and subsequent loading in the case of pull-through drafting units, there is a strong cut in the band with a subsequent thick point. This thick point accumulates in front of the compressor 5, so that when the stretching unit starts up, the belt normally breaks at the preceding interface.
