LBH-25V
Semi-automatic butyl extruder for rigid spacer frames
With the LBH-25V, butyl is applied to both sides of the fixed spacer frames. This butyl cord, which is placed precisely in the centre of the spacer side surface, serves as the primary waterproofing seal after pressing with the glass sheets to form an insulating glass unit. Frame widths of 6 - 24 mm can be processed, thanks to the infinitely variable nozzle adjustment. Rectangles, shapes or shapes with arches or even frames with built-in Georgian bars can be butylised without any problems.
How is the semi-automatic butyl extruder configured?
The butyl is heated in a heated butyl pressure system with a capacity of 14 litres and transported to the butylation nozzles on the filling head. A belt transport unit and pressure roller system ensure the constant feed of the frame. A modern control panel with clear visualisation guarantees convenient operation of the system.
How does spacer frame butylation work?
The spacer frame is manually placed on the conveyor belt and guided through the laterally arranged butyl nozzles in the filling head. A butyl strand is applied to both sides of the spacer profile.
Who is the LBH-25V suitable for?
The LBH-25V is the ideal complement to the semi-automatic desiccant filling systems for all small and medium-sized operations. Large insulating glass manufacturers with fully automatic butyl extruders can additionally use the LBH-25V for the production of shapes.
What advantages does the system offer?
The precise frame feed and the parallel-pressing hold-down rollers enable the spacer frame to be guided evenly and centrally through the butyl nozzles. This ensures an even butyl application on both sides. The LBH-25V has an automatic width adjustment of the nozzles by measuring the spacer width in a scanning device. The 14 litre butyl cylinder means fewer refills are required. A swing-out butyl cylinder and the included butyl fork ensure a quick and convenient refilling process. Butyl storage tank heating can also be automated via an integrated weekly timer, for maximum efficiency.
- Automatic width adjustment from 6 - 24 mm by measurement
- Ergonomic, due to infinitely adjustable height
- Processing of spacers with Georgian bars
- Straightforward butylation of arches and shapes
- Additional lateral guide rollers for frames with Georgian bars or very narrow frame profiles
- Equipping the butyl extruder with an adapter for processing additional frame widths (+ 18 mm)
- Inlet and outlet side (detachable) support extensions for safe frame guidance with very large formats
The Highlights
Even coating of rectangles and shapes
When processing rectangular shapes, sensor-controlled hold-down rollers stabilise the frame to ensure an optimum coating quality. The hold-down rollers can also be switched off as required, to the facilitate processing of shapes. Furthermore, there is a special pressure roller for the butylation of arches.
Progressively adjustable working height
Thanks to the vertical hoist, the working height can be easily adjusted to fit the operator and to suit the frame size.
