Abstract
An arrangement for welding multi-ply staggered bags has two guiding elements for guiding a multi-ply material so that the inner ply is staggered with itself and one part of the inner ply is staggered on another part thereof, a heating aggregate which supplies hot air for welding, and a bending member arranged to bend the staggered parts of the inner ply so that they partially separate from one another and form a gap into which the hot air from the heating aggregate is supplied.
