Abstract
In a method for the production of mailing bags, including envelopes, from material in web form, the material is processed in numerous ways and at least two separately prepared parts are transported to a joining station and there joined to one another with an adhesive. The two parts, at least one of which is already provided with the necessary adhesive, are placed one upon the other during an arcuate movement and joined to one another, in order to increase the speed of production. Particularly, at least one of the two parts (6, 7) and/or its carrier, performs an undulating movement in the region of the joining station (5).
