Among other things, in the automotive sector, in furniture construction or in the insulation material sector Honeycomb panels or honeycomb core is used.<\/p>\n
Gluing honeycomb panels or honeycomb panel cores is a frequent application on glue application machines from Axel Wirth Maschinen GmbH.<\/p>\n
Application examples are:<\/p>\n
The challenge here is that the glue has to be applied to the webs of the honeycomb core without tiling into the cavities.<\/p>\n
But the application amount must be so high that lamination is possible and firm.<\/p>\n
To do this, the viscosity of the adhesive, the roller surface and the production speed must match.<\/p>\n
In rare cases, the adhesive is foamed before application, we also have solutions for this.<\/p>\n
The foaming increases the surface of the applied adhesive, so a larger amount of adhesive can be applied to the small area of the bars.<\/p>\n
Our roller application machines are often used for this LW 100,<\/a> LW 120<\/a>, or DWO<\/a>.<\/p>\n The machines are either used as standalone machines or in a chain with expansion of the honeycomb cores, glue \/ glue application, lamination and press.<\/p>\n Dispersion adhesives, which are applied with grooved rollers, are mostly used on our systems.<\/p>\n This can be done either in the direction of travel or in reverse.<\/p>\n
