Abstract: An apparatus for guiding a strip consisting of a stiff material and cambered in the transverse direction includes a rotary member having a contact surface against which at least a portion of the strip bears in such a way that in that portion the strip exhibits a longitudinal curvature about at least one transverse axis, with the transverse camber being at least reduced resiliently. In order for the strip to be supported on the apparatus in a substantially play-free and slip-free manner so that the strip can carry a compression loading in a longitudinal direction thereof towards the apparatus, the apparatus further includes first and second lateral support surfaces which are disposed in mutually opposite relationship on respective sides of the contact surface and which are inclined towards each other so as to converge in an outward direction.
