Device for the assembly of pocket spring strings
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.
1. A device for the assembly of pocket spring strings to form a spring core for mattresses, comprising:
receptacles for pocket spring strings formed of pocket springs,
a transfer mechanism for transferring individually fed pocket spring strings from an insertion position (a) to a transfer position (c), and
a pushing-in element for transferring the pocket spring strings from the transfer mechanism to an assembly device,
wherein the transfer mechanism comprises a rotatably mounted drum, at the periphery of which are formed groove-shaped receptacles into which the pocket spring strings can be inserted and transferred from the insertion position (a) to an adhesive-bonding station (b), above which is arranged an application device for applying an adhesive, and
wherein the width of the receptacles can be set and adjusted to the height of the springs to be processed by parallel displacement of the supports forming the receptacles.

wherein there are arranged in front of the drum two conveyor belts which are drivable so as to rotate parallel to the axis of rotation of the drum and the mutually facing strands of which are located at a spacing from one another which is less than the height of the pocket spring strings.
4. The device of claim 3 , wherein the mutually facing strands are arranged so as to run conically towards one another in the entry region.
5. The device of claim 3 , wherein an advancing element for transferring the pocket spring strings into the receptacles is arranged in front of the conveyor belts.
6. A device for the assembly of pocket spring strings to form a spring core for mattresses, comprising:
receptacles for pocket spring strings formed of pocket springs,
a transfer mechanism for transferring individually fed pocket spring strings from an insertion position (a) to a transfer position (c), and
a pushing-in element for transferring the pocket spring strings from the transfer mechanism to an assembly device,

wherein webs are arranged at regular spacings on the periphery of the drum and hold the springs in the spring strings in a precise position on the drum.
7. The device of claim 6 , wherein the webs are mounted so as to be axially displaceable to the respective diameter of the springs in the spring strings.
8. The device of claim 6 , wherein the webs are fastened to strips which lie parallel to the shaft and by which the webs are displaceable axially by half a spacing between respectively two springs in the pocket spring string.
9. The device of claim 8 , wherein the axial displacement of the webs is effected manually or via a drive.
10. A device for the assembly of pocket spring strings to form a spring core for mattresses, comprising:
receptacles for pocket spring strings formed of pocket springs,
a transfer mechanism for transferring individually fed pocket spring strings from an insertion position (a) to a transfer position (c), and
a pushing-in element for transferring the pocket spring strings from the transfer mechanism to an assembly device,
