A device for forming a tube from a material web, in particular a film, which can be used for example for wrapping articles conveyed in a series one behind the other, and relates to a corresponding operating method. The device includes a bearing device for a roll of material web, a deflecting device for the material web and a drawing device, which is capable of moving the material web through the deflecting device. In the deflecting device, at least one first deflecting edge and one second deflecting edge are formed, wherein the first deflecting edge is shaped for deflecting the material web substantially transversely in relation to the longitudinal direction of the material web and wherein the at least one second deflecting edge is formed for folding the material web along at least one line running in the longitudinal direction.
