Art. AT HT

“T-Shape” Flexible spacer applicator

The flexible profile applicator Art. AT HT offers a perfect result in IG with “T-Shape”spacer processing. The profile is stored (up to 4 reels) in a special hermetic cabin next to the machine. Art. AT HT is available in 4 version, to process IG units up 6,000 x 3,300 mm. Art. AT removes the protective films on the sides of the profile and spreads the butyl at the intersections, in a non-stop extrusion system. The profile buffer (patent) allows to prepare in advance the profile, obtaining a uniform butylation and minimizing slowdowns. Art. AT HT can process both rectangular (also in self-learning mode) and shaped glass. At the end, the Corner Tape applicator closes the frame on the joint.

Art. AP HT

Flat Coupling Press With Gas Filling

The Art. AP HT coupling press with gas filling performs the coupling and pressing of insulating glass units quickly and with absolute precision, managing both rigid, flexible and thermoplastic spacers (with a special option in the case of thermoplastic product). It can fill one or more chambers with different types of gas, even in the case of offset units. Sensors detect the thickness of the pane, the thickness of the frame and butyl and the dimensions of the sheet, to calculate the volume of the chamber and the amount of gas required. Art. AP HT can also be equipped with a double circuit for the emission of the gas (argon/krypton).

Art. FP HT

Quality Check and Frame Positioning Station

The inspection and frame positioning station Art. FP HT is available in four different models with different maximum workable formats, up to 6000 x 3300 mm. During processing, sensors acquire the pane format and the mobile bars, equipped with a LED light system, are positioned automatically. The inspection room, with a special black structure, allows the check of the rear side of the glass. The Art. FP HT offers many additional devices: automatic reference bars, adjustable brightness rear LED lights, automatic upper references, access door for reaching the back of the line, etc.

Art. AC HT

Rotating Corner Conveyor

The Art. AC HT automated corner conveyor turns either glass sheets or double glazed units safely and efficiently. It uses and maximises the available space in the glasswork, without interrupting overall production cycle. The conveyor can join together machines at any angle other than 0° (usually 90°), rotating counter clockwise and clockwise. It optimises production thanks to its perfect synchronisation with other production line machineries.

Art. SR HT

Sealing Robot

The automatic sealing robot Art. SR HT is equipped with exclusive devices to guarantee a high quality sealing and at the same time a superior production capacity. Art. SR HT can process IG units with a capacity of up to 400 kg per linear meter and offset units up to a total thickness of 100 mm. It can also process double, triple or quadruple panes, using up to 3 different sealants. The double suction cup drive accelerates the passage of the sealed units, allowing the finished piece to be unloaded without delaying the sealing of the next piece. To avoid processing slowdowns, the Art. SR HT sealing robot can been equipped with an automatic dosing unit changeover sistem. Special features developed by Forel ensures the precision of sealing.

Thermoplastic Spacer Applicator

Thermoplastic spacer applicator Art. TA has been developed on the basis of two key principles: productivity and ease of use. The interface includes all the most widely used work programs and specific options for thermoplastic products. The product is pumped from the drum to the recirculation units, that work in tandem guaranteeing non-stop extrusion. The benefits of this configuration are particularly clear when the drum needs replacing. A temperature monitoring system, with many check-points along the entire length of the conduit, ensure uninterrupted product extrusion.


Art. RC HT

Turning Conveyor

The turning conveyor Art. RC HT can rotate at any angle, clockwise or counter clockwise. It can be installed in-line or as a corner conveyor, depending on the user’s requirements. It allows the best possible arrangement of space, with a machining process that does not require interruption of the production cycle. Usually, Art. RC HT is used to turn the glass of 180°, orientating low-emissive glass coatings correctly, thus facilitating the production of glazed units with 2 or more sheets. Art. RC HT optimizes production, thanks to the perfect synchronisation of all the line machinery. Unlike the “Residential” model, in Art. RC HT the glass sheet is supported by an air cushion technology.

Art. MB

Manual Butyl Extruder

The Art. MB butyl extruder ensures full compliance with the most stringent standards required for the primary seal. The Butyl rubber is dispensed by two extruder nozzles through two separate dispensers, which ensures an uniform distribution around the whole perimeter (a special feature unique to Forel). The touch screen unit manages at the same time the automatic opening of the nozzles (width adjustment) and the positioning of the pre-extrusion guides, according to the selected spacer width value. The injection capacity (grams of butyl rubber per linear metre) can be set directly. Art. MB is able to apply butyl rubber on shaped profiles or Georgian bar frames, with exceptional accuracy and simplicity of operation. Preproduction heating can be pre-set to automatically turn on.

Art. DF

Desiccant Filler

The Spacer Processing range of Forel is completed by the Desiccant Filler Art. DF. Consisting of a turret holding a frame-pressing vice, and two special drilling and filling heads, this solution can process frames of any form, whether rectangular or shaped. Art. DF can also be fitted with an automatic frame loading/unloading system; in this way, the desiccant loader can be automatically fed and the butyl application unit can be topped up immediately afterwards.

Art. CA

Cork Pads Applicator

The Art. CA automatic cork pads applicator further optimize the IG unit production process. The solution is equipped with 4 or 5 applicator heads, automatically positioned according to the height of the glass pane and the varying needs of the operator. Each movable head is fed from a material reel, which is easily and rapidly replaced. The material unwound from the reel is cut and applied to the moving glass. The operator uses software to set the distance between the applied pads.

Art. SQ

Quality Control Scanner

The Art. SQ scanner performs real-time quality control on the glass by detecting defects, indentations or microfractures, and displaying them on the monitor, alerting the operator immediately. A combination of innovative software and technology allows this scanner to detect accurate information as the glass is moving along the insulated glass production line conveyor or on a glass processing line conveyor. This solution is equipped with a dedicated software that produces images with a resolution of up to 400 dpi (0.0635 mm). The defects detected by the scanner can be categorized by the user according to the type and size of defect, and can be achieved for future reference and analysis.
