The four-sided application on profiles requires sophisticated technology. Supplied by Axel-Wirth-Maschinen GmbH
Among other things, in the automotive sector, in furniture construction or in the insulation material sector Honeycomb panels or honeycomb core is used.
Gluing honeycomb panels or honeycomb panel cores is a frequent application on glue application machines from Axel Wirth Maschinen GmbH.
Application examples are:
The challenge here is that the glue has to be applied to the webs of the honeycomb core without tiling into the cavities.
But the application amount must be so high that lamination is possible and firm.
To do this, the viscosity of the adhesive, the roller surface and the production speed must match.
In rare cases, the adhesive is foamed before application, we also have solutions for this.
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.
Our roller application machines are often used for this LW 100, LW 120, or DWO.
The machines are either used as standalone machines or in a chain with expansion of the honeycomb cores, glue / glue application, lamination and press.
Dispersion adhesives, which are applied with grooved rollers, are mostly used on our systems.
This can be done either in the direction of travel or in reverse.
You are welcome to try it in advance at our technical center . If necessary, simply contact us and make an appointment with us in Oberkochen.
In Scandinavia, this is a standard procedure to protect wood.
On the one hand, there are soaps from the industry that are supplied ready-mixed and can be easily
can be easily applied on Wirth roller application machines.
On the other hand, customers mix their own soap.
Depending on the viscosity of the liquid, several applications are necessary.
After application, "Wirth" spreader units are often used.
Under conditional general conditions, cold PU adhesives, glue spreaders, 1KPU, 2KPU, roller application by glue spreaders or roller application can be rolled on with repeat accuracy.
The rollers can be removed for cleaning and can be made chemically resistant to the cleaners. With a rubber selection based on six different basic rubber types, our team will find the right rubber for cold PU adhesives and their cleaners.
In addition to the basic rubber types, we have well over 100 different roller surfaces in use with customers.
Due to the variety of roller surfaces and the adjustment possibilities on the machines, application weights of 5 - 800 g/m² are possible.
The glue application machines from Wirth are very easy to dismantle and clean. This is especially advantageous for PU adhesives.
The main parts of the machine are made of stainless steel and therefore insensitive.
The following machines are frequently used for these adhesives:
Glue application machine Typ LW 100
or
Glue application machineTyp LW 120
or
The following can be processed 1KPU or also 2KPU Adhesives.
Connections are for example:
is characterised by precise work with demanding adhesives, glues and adhesives.
The wealth of experience grows from day to day. In addition to regular tests at our company, a large number of machines are also running in the laboratories of glue manufacturers.
Suitable for applying cold PU adhesives are the machine types LW 100 and LW 120 or the dosing roller machine type DWO 120.
Every customer can take advantage of the opportunity to test the glue spreader with their own PU glue at our premises in Oberkochen.
In our Demonstration room or test workshop sample productions can be manufactured and tested close to reality.
Thus, every customer can see and test the steps of mixing, applying and cleaning. Likewise, different application quantities with different roller surfaces can be shown. The customer gets exactly what he has seen and tested in advance..
