Roba Press

Roba Press

Roba Press 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.

The block melter is used to fill glue tanks on edge banding machines, automatic book binding machines, etc., with PUR hotmelt. The appliance serves to melt polyurethane hotmelt which must not come into contact with the ambient air during storage and conditioning for processing.

After the appliance is switched on, it is heated to the defined readiness temperature. If the fill level in the glue tank is too low, the block melter is heated to the programmed operating temperature. As soon as this higher temperature is reached, the cover slide opens and the pressing cylinder presses the PUR block onto the melting grate. The contact pressing and melting process lasts until the glue tank is full again. In the interest of gentle handling of the PUR adhesive the appliance’s temperature is reduced to the readiness value again as soon as the glue tank is full. The pressing cylinder stops immediately after filling and the cover slide closes again to ensure that no ambient air reaches the block of PUR

RobaPress is suitable as a premelter for edge–banding machines, spine binding systems and other PUR roller application systems.
