The coiling apparatus for flexible planar articles (44), in particular printed products such as newspapers, magazines and parts thereof comprises a winding core (16), which is rotatably journalled in a frame (12) and drivable by a drive shaft (28), and a coiling band (24) which directs the flexible planar articles (44) essentially tangentially to the coiling core and is wound up onto the coiling core together with the planar articles. A drive train comprising a driving disc (38), a drive belt (40) and a drive belt disc (42) makes it possible to rotate the shaft (14) on which the winding core (16) is rotatably mounted from the same motor as drives the band reel (26). Between the winding core (16) and the rotary shaft (14) there is located a spiral spring (18) which is secured at its one end (20) to the winding core and at its other end (22) to the rotary shaft (14). The arrangement is so devised that the end (22) of the spring (18) can be moved relative to the spring end (20) in order to change the state of tension of the spring. The apparatus makes it possible in this manner to adapt the torque exerted onto the coiling core to the increasing coil diameter during winding up of the coiling band (24) with the planar articles (44). A regulating system is not necessary.
