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