Mattress production: roller applications
For mattress manufacturing, roller application is the most efficient way to set up a highly automated high-quality production line. The adhesive is evenly applied to the foam layers with a double roller. This method is very efficient because no adhesive is wasted due to overspray and the application quantity required is extremely small.
If the production line with the roller coater can be adjusted precisely, the adhesive coat will dry very fast. In the inline production of mattresses, roller coating is used as a standard, often in combination with force dried adhesives. After application, such adhesives must be dried in an infrared drying tunnel or a circulating air oven before placing the next foam layer on top. As the glue is already dry at this point, the production can continue immediately and at the end of the process, the mattress can be packaged instantly after gluing the last pieces together.
Whether using spray-guns or a roller application, one component adhesives are the way to go for bonding different layers of foam. SIMALFA® 3031 is one of our one component foam-specialist adhesives with a wide range of use cases. It is suitable for all industries and bonds any kind of upholstery material. This wet-contact adhesive only requires a small application quantity to stick instantly and strongly. Because of the low quantity and its special formula, the drying time of SIMALFA® 3031 is extremely short. Additionally, the adhesive distinguishes itself by its outstanding flexibility and heat resistance.
In its original form, SIMALFA® 3031 is applied as one component, but to boost the instant tack, an accelerator can be added. To achieve the best mixing proportion of the two components and to enable a flexible adding of the accelerator, we developed our patented on-demand application system. By pressing a button on the spray gun, the accelerator boosts the instant tack.
