Abstract

The invention relates to a vertical former with a vertical double sieve (DS). In the formation section (12), mutually opposite different forming elements (18, 19, 20, 21) are arranged, in order to achieve an improved formation in association with an improved web strength and in particular a more uniform web structure. <IMAGE>
