DUERO – ROBUST MULTI-BEAD APPLICATION HEAD FOR MATTRESS PRODUCTION

Duero derives from “duro” and “durable” – and that is exactly how it presents itself: robust and resilient. The electro-pneumatic multi-bead application head was specially developed for the requirements of the automatic mattress production. With this jetting head, you can reliably and efficiently glue both the mattress frame and the large surfaces for the mattress core.

ADVANTAGES OF THE DUERO AT A GLANCE

  • Robust design for harsh environmental conditions
  • Suitable for just-in-time mattress production
  • Efficient frame gluing in the longitudinal and transverse direction with the same application head
  • High-volume jetting elements for high-quality gluing of the mattress core made of pocket springs or foam
  • Suitable multiple application heads for your application: Select from various designs with different bead distances and nozzle diameters.
  • Control via PLC (24 VDC connection) or the pattern control integrated into the Robatech melter

JERKY CHANGES OF DIRECTION? NO PROBLEM FOR THE DUERO!

The application head travels back and forth, lengthwise and crosswise – again and again. And with every change of direction, there is a little jolt. When applying the adhesive strips in the automatic mattress production, the multi-bead application heads are subjected to high kinetic loads. This is no problem for the Duero. This jetting head was specially developed for such harsh environmental conditions. The proven, robust components are durable and low-maintenance – ensuring consistently reliable gluing.

EFFICIENT MATTRESS FRAME GLUING WITH MULTIPLE BEADS

Do you want to apply the adhesive for mattress frame gluing fully automatically? The adhesive is applied to the mattress’s foundation in longitudinal and transverse strips with the Duero multi-bead application head. The jetting elements are mounted on two sides of the application head and controlled individually. This means that one application head can be used for both the longitudinal and the transverse direction.

High-quality adhesion in frame gluing can only be achieved if sufficient adhesive is applied. The open time must last long enough so that the adhesive can be applied all around the frame. Only then can the side padding be applied. The Duero applies sufficient adhesive for strong adhesion with a nozzle diameter of 0.5 mm to 2.00 mm.

MULTI-BEAD APPLICATION FOR RELIABLE MATTRESS CORE GLUING

Do you want to automatically apply the adhesive for the mattress core at the same time as gluing the frame? You can glue the mattress core reliably and quickly using straight or wavy beads – regardless of whether it is a pocket spring core or foam. A multi-bead application has the advantage that the open time is longer and the individual layers of the mattress, therefore, adhere well. You can obtain the right amount of adhesive by selecting the appropriate nozzle diameter.

DUERO: AN APPLICATION HEAD WITH MANY FACES

What does your adhesive pattern look like? What kind of materials do you want to glue with it? And how large should the adhesive volume be? Answers to questions like these decide which version of the Duero multiple application head is right for you – because the Duero offers a wide range of variants.

Different Duero designs

Examples of possible Duero designs

Up to four jetting elements can be mounted on one application head. These elements are designed for large flow rates. One jetting element simultaneously supplies up to five nozzles with liquid hot-melt adhesive. The jetting elements are enabled or disabled application-specifically. This means you are ideally equipped for just-in-time mattress production. Finally, by selecting the nozzle diameter, you determine the amount of adhesive to be applied.

With Duero, we offer you a multi-bead application head for large adhesive flow rates at a good price-performance ratio. Let us know how many beads you need, how thick they should be, and at what intervals they should be applied. We will be happy to discuss possible designs with you.
