ABSTRACT:
To turn through 90.degree. sheets passing at a rapid rate over a roller conveyor in a horizontal plane, a device is proposed which comprises a pair of rollers entrained in rotation at different speeds and spaced apart from each other and from a longitudinal guide on the conveyor transversely with respect thereto. Each of the rollers has its rotation axis inclined with respect to the normal on this guide, by a specified angle which is greater for the roller which is closest to the guide and the rotation speed of which is the smaller. Each of the rollers has its periphery in contact with a support ball or with the lower face of a sheet during its passage, substantially in said transport plane.
