According to the invention, the support rollers supporting the two aprons are mounted on the casing proper of the spindle via two support arms, one of the support arms of each pair being subjected to the action of pressure for ensuring tension of each apron and at least one of the other two support arms being mounted in articulated manner on the casing. Parallelism between the axes of the rollers is not able to be respected.
