Guiding device

A guiding device for guiding a flexible strip comprising a guide roller that is rotatable about a roller axis and that has an exterior guide surface extending in a circumferential direction about the roller axis for guiding the flexible strip, wherein the guiding device further comprises a support for supporting the guide roller relative to a guide path for the flexible strip, wherein the guide roller comprises a plurality of roller segments juxtaposed in an axial direction along the roller axis for forming the exterior guide surface, wherein the plurality of roller segments are movable relative to each other to enable the guide roller to be positioned in a first bend state in which the roller axis extends along an arc, wherein the plurality of roller segments are interlocked to rotate together about the roller axis in said first bend state, wherein for each pair of two consecutive roller segments, one roller segment of the two consecutive roller segments comprises a plurality of first teeth and the other roller segment of the two consecutive roller segments comprises a plurality of second teeth, wherein the plurality of roller segments extend over an arc length along the arc of the roller axis, wherein the first bend state is a maximum bend state in which said arc length is at least ninety degrees, wherein the roller segments have an outer diameter, wherein the roller axis in the maximum bend state extends along an arc with an arc radius, wherein the ratio between the arc radius and the outer diameter is less than five, wherein the guide roller, in the maximum bend state, has an inner radius and an outer radius with respect to the center of the arc, wherein the plurality of first teeth and the plurality of second teeth are arranged to interlock at both the inner radius and the outer radius when the guide roller is in the maximum bend state.
