The device (1) for the assembly of pocket spring strings (3) comprises a rack (15), on which a drum (13) having receptacles (19) for pocket spring strings (3) is rotatably supported. An operator B manually places the pocket spring strings (3) into the receptacles (19) and rotates, or initiates the rotation of, the drum (13) about a predetermined angle, for example 60º. Now, the operator B places a further pocket spring string (3) into the subsequent receptacle (19), and at the same time an adhesive is applied to the advanced pocket spring string (3). Following a further rotational movement of the drum (13), the next pocket spring string (3) is inserted, an adhesive is applied to the previously inserted pocket spring string (3), and at the same time the pocket spring string (3) to which the adhesive was applied and which is now located in front of the assembly device (25) is ejected.
