use the trimmings 57 39 and 58 39 until their wear threshold and then replace all of them unfortunately after such a replacement the freshly installed trimming 57 39 or 58 39 requires a some days long break in run during which the fabric is not perfectly processed all these time wastes resulting eventually in missed production or fabric quality lowering can be prevented by systematically operating according to the modalities provided according to the present invention clearly many changes may be supplied by those skilled in the art to the raising machine according to the present invention without departing from the scope of protection of the inventive idea and clearly when practicing the invention the shapes of the illustrated details can be different and same details may be replaced by technically equivalent elements for example for particular fabric types and or processes reversing the direction of revolution of drum 13 or 52 of the machine and consequently of the pile or counter pile processing cylinders 16 57 or 17 58 respectively could become necessary in that case both cleaning brushes 21 or 56 and 22 or 56 39 will operate on the other cylinder set opposite to the cylinder set on which they were operating before revolution direction reversal if the toothed belt sprockets or gear wheels transmission known from the prior art are adopted the only possible system for that purpose consists in introducing a mechanical phase shift by means of a clutch engagement disengagement device.
