Gasket insertion machine - DAW 100.H

Automatic, all-round gasket fitting

This machine, which has been used very successfully in window construction – in very many construction stages – since 1992, is a genuine alternative to the previous, elaborate manual stage of “inserting gaskets”. Enormous time-savings thanks to rapid processing as well as the clean, high-quality insertion of the rubber gasket are among the key advantages of this system.
The gasket insertion machine automatically inserts the gasket in window elements. The gasket is inserted along the sealing groove, around the corners.

Clean processing, perfect seat
The gasket is inserted in the window groove in a compressed state. The degree of compression can be set at the control. A special groove guidance system monitors and regulates the exact course of the rubber insertion unit along the sealing groove during the whole process. Optimised processing properties are achieved with the use of a wetting device for the balanced wetting of the rubber.

Frames and sashes
Depending on the production concept, the frames and/or sashes can be processed with up to 99 fields. A turning unit flips the window over onto the 2nd side for leaf processing. This means that the glass and stop side can be fitted with rubber gaskets. The machine can be fitted with two insertion units to process various gasket profiles – such as glass and groove gasket.

Automatic gasket changer
The automatic gasket changer facilitates fitting two gaskets with one gasket insertion unit. This means that two different coloured gaskets or two gaskets with similar geometrics can be mounted using one inserting unit. The machine only needs 5 seconds for the automatic switching of the two gasket strips.

The rubber gasket…
does not need any thread to stabilise the material. The use of coloured gaskets – alongside the standard black rubber gasket – perfectly rounds off the optimum design of coloured windows. EPDM and TPE or other similar gaskets in various designs are used.

Seal insertion – rabbet seal
The rabbet seal is fitted on the circumference of the sash. Optionally, a V-shaped notch may be cut on the corners.

The gasket stop
The gasket stop can optionally be placed on one of the 4 sides of the window, projecting our or with mandatory ventilation. There is no need to bond the ends of the gaskets due to the compressed assembly.

Seal insertion – glass seal
The glass seal is inserted one on each side, since in most cases there is no circumferential groove. The ends of the seal are cut square.

Welding of the seal ends
The downstream welding plant fully automatically welds the seal in the corners. By welding of the seal ends, the four single seals become one circumferential glass seal.

The profiles
The seal insertion automats process profiles with a variety of geometries and dimensions. The pallet of profiles can always be extended afterwards.

In the case of glazing bar sahes
in the case og glazing bar sahes gasket insertion is necessary only on three sides of the element. The machines can accommodate the glazing bar position on all 4 sides of the sash.

Easy handling
The control reports the end of the gasket. To “reload”, the operator places a new reel or box on the gasket feed and neatly bonds the old end to the new end of rubber.

Modern control
The processing data can optionally be made available online via the central network, by disk or manually. It is also possible to run the system with self-detection. A modem is integrated in the control for quick, uncomplicated teleservice.

Our experience – your benefit
For many years LEMUTH gasket insertion machines have suc-cessfully proved their worth in practice in many window construction companies.
Various applications – whether as stand-alone versions or high-speed systems in production lines for the 1 minute rate - characterise the flexibility in use.
