To manufacture filled containers (54) from a web which can be stood on their bases, container parts (15, 16) are first deep-drawn on both sides of a centre line (M) extending in the conveyance direction with hollow channel parts (23, 24) which extend towards the web edges (5c, 5d) but terminate at a distance (A) from the latter. Then the web parts (5a, 5b) situated on both sides of the centre line (M) are folded upwards while being heated around said centre line, which thereby becomes the folding line (36), to form upwardly open containers and are sealed in a first sealing station (7) on their circumference with the exception of the circumference of the upwardly projecting hollow channel parts (23, 24). The web edges (5c, 5d) in the region of the hollow channel parts are then opened up and the containers are filled through the opened-up hollow channel parts. Subsequently, the opening-up is terminated and the containers are sealed in a second sealing station (9) in a manner such that the circumference of the hollow channel parts is also sealed. Then opening aids are produced in the area of the hollow channel parts so formed and the filled containers (54) are separated individually or into groups. A suitable apparatus comprises a stock station (1) with a roll (2) of web, a conveyance device (3, 3a), a deep-drawing station (4), a heating station (6), one first and second sealing station (7 and 9) in each case and one first and second punching station (10 and 11) in each case. <IMAGE> |
