Butyl extruding

• Suitable for coating rectangular and shaped spacer frames as well as for spacer frames with muntin bars
• Automatic and speed-dependent adjustment of the hold-down rollers as well as nozzle opening and closing
• Specially designed hold-down rollers for radius-shaped spacers
• Processing of different spacer heights by adjusting the nozzle height
• Infinitely adjustable pressure, temperature and coating speed

Precise coating

• Convenient and fast refilling of the sealant into the vertically tilted material cylinder with a quick-change attachment
• Automatic evacuating system and low-level indicator
• Timer for preheating the sealant material with a weekly program sequence
• Short heat-up cycle thanks to optimized heating circuits
• Low energy consumption in standard operation, low-noise operation

• Stepless automatic nozzle adjustment for spacer width from 5–24 mm (0.20–0.94 in), 12 pre-adjustable spacer widths possible
• Interruption-free, long-term operation using 200-liter butyl drum pump system
• Frame transport system incorporating servo motors as well as application speed control for reliable application also on the corner sections
• Positioning stops and frame guiding for speedy precise, high-repetition application
• Gentle turning of spacer frames with stepless adjustable rotating speed, dependent on spacer frame dimension
• Double gripper system, automatic outer gripper activation for safe support and fast rotation of larger frames
• Sealant feeding to nozzles using a temperature-controlled pipe system with controlled heating circuits for gentle material treatment
