filaments also pass into the feed tube 7 of the part 18 of the revolving spindle 6 which is rotated by means of a belt not shown a piled up wad first forms in the region of the orifices 12 and is wound around the sleeve 10 of the spindle 6 the wad is then subjected to the action of the cutting blade 14 and the stripping device 15 collects the fibers obtained which are sucked into a box not shown the device according to the invention thus makes it possible to obtain fibers possessing disordered crimps and being of non uniform cut the fibers therefore have a cutting diagram similar to that of wool the depth of the cut can be adjusted and it is possible if so desired to place several cutting components on the same apparatus in addition it is possible to provide for the introduction into the space between the sleeve of the spindle and the tube of a gas or a liquid for example dyestuffs size antistatic agents and the like it is also possible to provide lateral perforations on the part 18 of the revolving spindle situated near the injecting device through which a portion of the fluid can escape furthermore the spindle can be heated internally and can be controlled either from the outside or from the inside other means may be provided for either heating the product or cooling the product over the entire length of the apparatus this apparatus makes it possible to cut the piled up wad completely or partially when cut partially the stripping device is not utilized nor is the part of the frame near the.
