The invention relates to a novel method for producing a formwork tube (1) of planar material by winding on a winding machine. In order to provide a multi-layered formwork tube wall (2), several webs (4a, 4b) of the planar material are wound using a winding spindle (3) in such a manner that the layer (4a', 4b') of the formwork tube wall, which is produced by each web, is overlapped by at least one adjacent layer, wherein a rip cord formed by a web-shaped material is introduced during the winding process between the at least one layer adjacent to the winding spindle and another layer and the respective formwork tube is produced by separating it from the blank product. |
