ABSTRACT OF THE DISCLOSURE Apparatus for cutting through a web of flexible material for making tubular containers is described. The web is partially formed into its final shape and to this end it has longitudinal fold lines and spaced lateral incisions which permit marginal portions of the web to be folded over and overlap at their free edges. At a later stage in the making of the tubular containers it is necessary to accurately position the web so that it is cut completely through exactly where the lateral incisions are located. In the application of the invention, the edges of the web defined by the incisions form a stop which engages a cutter thereby accurately positioning the web for cutting.
