Abstract (en)
[origin: WO2018042099A1] The invention relates to a method for conveying a low-tension flexible belt or strip (2), made of fabric or composite material, over a length of more than 30 m and at a speed higher than 600 m/min. The method consists of unwinding and returning the belt or strip (2) by means of a plurality of pairs of rollers (4, 5) which are motorised and rotated at identical speeds, each pair of rollers (4, 5) consecutively driving a first surface (2a) of the belt or strip (2) by means of a first roller (4) rotated in one direction and a second opposite surface (2b) of the belt or strip (2) by means of a second roller (5) rotated in an opposite direction.
