The transport roller has two separate, mutually parallel end flanges (2,3) and an intermediate centre part (4) with a passageway (6) passing centrally between the flanges and centre part. The centre part has at least one annular peripheral part (15) that can rotate separately from the flanges. Both flanges are connected together and to the peripheral part so that both flanges are in a rest state independently of a rotation of the peripheral part caused by a contact with the conveyor track. |
