A hose (1) of a flexible plastic material is designed so as to be reformed into a web (2) with mutually sequential packaging blanks (26) separated by transverse slits (27). The hose has a region (15) oriented in the longitudinal direction which is cut on the formation of the web (2). At least one longitudinal thickening (14) is included in region (15). A device for reforming the hose (1) into the web (2) has retainer devices (33a, 33b) provided with a channel having a gap whose width exceeds the thickness of two adjacent hose walls (11a, 11b). A slitting device is located in the channel. Cutting and welding devices (37, 39) form the transverse and longitudinal slits (27, 29) and also form transverse connecting zones between the walls (11, 11b) on either side of each transverse slit (27). |
