Abstract: 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).

Abstract: A multi-cell battery comprising a plurality of frames each divided into a number of side-by-side active paste support areas. The frames are assembled and secured together in a stacked formation so that the perimeter portions of the frames form the top, bottom and two opposite sides of the battery, and the divisions in the frames form cell partitions. Each frame is pasted with active material to form plates with adjacent plates in each frame being of opposite polarity and adjacent plates in adjoining frames also being of opposite polarity.
