RobaPUR 2 MOD

The RobaPUR 2 MOD adhesive adhesive melter is designed for processing different hot melt adhesives hot melt adhesives in block, granular, and cushion form. Particularly developed for demand-depending melting (Melt-on-Demand), it is suitable for processing almost all commercially available PUR adhesives as well as for PSA, EVA, and APAO hot melt adhesives.

The overall design of the RobaPUR 2 MOD is tailored to flexible production with short retrofit times. Switching between reactive and thermoplastic adhesives as well as color changes are quick and easy – without major cleaning effort. The innovative magazine and melting concept enables a significant increase in the melting rate to up to 10 kg/h. Depending on the pump selection, the adhesive melter can achieve delivery capacities of 9 – 12 kg/h. In highly dynamic processes (SpineCoat applications, adhesive binding in perfect binder soft covers 200 – 2000 T/h), up to 50 kg/h are possible.

  • Melt-on-Demand (MOD) technology ensures comprehensive protection of the adhesive characteristics of the melted material.
  • Processing of most commercially available PUR hot melt adhesives without additional inert gas flushing and active cooling.
  • Adhesive viscosities (depending on variant and pump type): 500 - 120,000 mPas
  • Adhesives with and without inliner
  • Self-calibrating level sensor for precise filling level monitoring
  • Consistent thermal separation between heating zones and magazine for high operating safety
  • Non-stuck coating for reduced and quick adhesive changes with different color (PUR applications in the woodworking industry)
  • TRM standard graphic panel for language-independent operation
  • Integrated AS IK 40 or AS IK 10 application control

The RobaPUR 2 MOD is available in three variants with different pump configurations. With that, the adhesive melter can be tailored optimally to customer- and process-specific requirements.

1-block magazine

The 1-block magazine is suitable for simple applications with low adhesive flow.

  • Magazine for 2...2.5 kg block.
  • Basin filling: Gerotor pump GPR 12, max. 9 kg/h, viscosities from 2,500 to 120,000 mPas
  • Nozzle application: Gear pump ZPR 12, max. 12 kg/h, viscosities from 500 to 120,000 mPas
  • For adhesives without inliner

2-block magazine

The 2-block magazine is recommended for applications with high adhesive flow. Compared to the 1-block magazine, significantly less refilling intervals are required and the process performance is improved with increased production due to higher magazine filling.

1-block magazine with press

The 1-block magazine with press is available for highly dynamic processes. It was specially developed for the use in clocked PUR applications of the bookbinding industry.

  • Magazine for 2...2.5 kg block.
  • Basin filling: Gerotor pump GPR 12, max. 9 kg/h, viscosities from 2,500 to 120,000 mPas
  • PUR spine nozzle application: Gear pump ZP3 S, max. 50 kg/h, viscosities from 500 to 10,000 mPas
  • For PUR hot melt adhesives with inliner

Thanks to the high melting rate and different configurations, the RobaPUR 2 MOD can be used in different applications and processes:

  • Packaging industry ISC 200
  • Graphical industry ISC 300
  • Textile industry ISC 590
  • Wood industry ISC 690
  • Construction supply industry ISC 790
  • Automotive industry ISC 820

Typical areas of application of the RobaPUR 2 MOD are basin filling, manual application using a hand applicator, as well as bead and surface application with nozzle systems.

RobaPUR 20 MOD

RobaPUR 20 MOD is a special solution for careful melting PUR hot melts.

The patented MOD (melt-on-demand) technology melts only the necessary amount of adhesive. This sealed air tight system keeps the adhesive in perfect condition with minimal change in viscosity and prevents moisture curing as well as harmful vapors.

The device is especially suitable for variable operating conditions with pauses in format or product changes.

  • Suitable for processing adhesive blocks from 20L drums, with or without liner
  • Up to two precision gear pumps for volumetric support
  • Refill without interrupting production
  • Cooled melting grill
RobaPUR 35 MOD SpineCoat

The RobaPUR 35 MOD SpineCoat adhesive melter is specially designed for the melting and pumping of reactive polyurethane hotmelt adhesives.

The RobaPUR 35 MOD SpineCoat adhesive melter is designed to be used with the SpineCoat coating nozzle for book adhesive lines. The adhesive is pumped by a gear pump powered by a very dynamic servo drive. The technology assures accurate volume control along the entire length of the application.

  • Melt-on-Demand (MOD) technology for a protective adhesive processing
  • Active melt grill cooling
  • Active dry air preparation
  • Easy operation
  • Integrated application control and volume control
  • Adhesive viscosity: 1,000...12,000 mPas
  • Feed pump: Gear pump ZP 3 S
MultiMelt

MultiMelt is a versatile melting tank for handling many types of EVA, PSA, APAO reactive adhesives such as PUR.

The easy-to-clean design makes it fast to switch between different adhesive bases with minimal downtime.

  • 1 and 2 gear pump versions
  • Short turnaround time
  • Convenient and easy to access
  • Energy-efficient design

MultiMelt Buffer

The MultiMelt unit can be used as a buffer tank (intermediate tank) when combined with a drum melter or any other premelter.

  • Capacity: 40 Liter
RobaPress

RobaPress is a ‘Melt on Demand’ system used to melt blocks of PUR hot melt.

The 2–3 kg blocks of PUR are in airtight containers and melted gently depending on demand. This produces no waste.
RobaPress is suitable as a premelter for edge–banding machines, spine binding systems and other PUR roller application systems.

  • Integrated buffer prevents burn through
  • Easy operation and maintenance
