With an installation for manufacturing conical objects from two webs (5, 6) of flexible material, conical valves for bags can be made in an efficient manner since a guiding device (8) is mounted consisting of two change-direction irons, (15, 16) positioned in the same planes as the ones in which the webs come out of the folding device. For the guiding device enables the folded webs to continuously shift into each other with the open sides facing each other. Furthermore the installation should have a chop-off device (10) a glueing device (19, 20) and a driving apparatus (17, 18). |
