- About LiSEC
With the LBH-60M semi-automatic butyl extruder, butyl can be applied at a controlled rate on both sides with fixed spacer frames and therefore with high precision. 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 4 - 60 mm can be processed, thanks to the infinitely variable nozzle adjustment. Rectangles, frames with built-in Georgian bars and shapes - even the butylation of arches during processing is straightforward with the LBH-60M.
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. The butyl transport system is identical in design and has a volumetric control system, so that the butyl application on the spacer frame is exactly the same on both sides of the frame. 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.
The spacer frame is manually placed on the conveyor belt and guided through the laterally arranged butyl nozzles in the filling head. During this process, the set amount of butyl is precisely applied to both sides of the spacer profile.
The LBH-60M is the ideal complement to the semi-automatic desiccant filling systems for all small and medium-sized operations. However, large insulating glass manufacturers with fully automatic butyl extruders can additionally use the LBH-60M for the production of shapes.
The precise frame guidance guarantees that the spacer frame is accurately centred and guided through the butyl nozzles by means of parallel pressing hold-down rollers, thereby ensuring uniform butyl application on both sides. The intuitive operating concept offers the option of creating the most common spacer profiles as favourites. Following selection on the control terminal, the nozzles move to the correct profile width and all parameters stored in the "recipe" are adopted. The 14 litre butyl cylinder means fewer refills are required. A swing-out butyl cylinder and the butyl fork provided allow a quick and easy refilling process. Butyl storage tank heating can also be automated via an integrated weekly timer, for maximum efficiency.
Even coating of rectangles and shapes
When processing rectangles and shapes, a sensor-controlled hold-down roller provides the necessary stabilisation of the frame and therefore ensures 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. This makes the LBH-60M particularly ergonomic.
Electro-pneumatic pressure control
The desired application quantity is precisely metered and adapted to the current belt speed by the electro-pneumatic pressure control. This means that even very large frames or shapes can be optimally processed by reducing the belt speed.
