Gluing machine RAFFAELLO

THE COMPLETE OFFER FOR ANY NEEDS

The machine allows to glue and to bind multiple typologies of cardboards and bookbinding materials, having a wide range of products such as binders, covers, photographic albums, etc. Using cold or hot glue with glue heater tank and recirculating pump, mixer and viscometer (OPTIONAL), sheet weight from 80 to 250 g/sm.

It is available with an induction space of 75, 105 and 120 cm and in the semiautomatic or automatic (only coupled with the complete line) version.

The machine is equipped with a stainless steel high diameter double roll system that provides the glue spread on the sheet surface uniformly while it is supported by two chromate-plated (or Teflon coated, depending on the version) parallel rolls. They are equipped with an automatic transmission chain tension adjustment. All the pinions have been oversized and quenched; the transmission chain is nickel plated. These solutions allows a lower wear and a longer duration.
The glue rolls can be reconditioned and easily extracted from the machine: in this way it is possible to extend the machine life, amortizing so the purchase even for low annual production.
The rolls rotation is made with a mixed toothed belt-gears system with an automatic recover of the belt tightening and the alternation with steel and fibreglass reinforced nylon toothed gears. In this way we have at the same time a longer duration and the noise reduction during machine working.

The glue pump it is made in Italy, it has an aluminium frame and the sliding inside elements made of stainless steel, it is equipped with anti-stall pneumatic system, it does not need lubricated air and allows the no-load working condition with suffer. It can be reconditioned with the specific spare kit.
The feeding and the return pipes are made of PVC with internal steel spiral with an high thickness.
The glue distributor is made with a square stainless steel pipe with machined and TIG welded tap joints.
4 or 5 taps are present (depending on the machine version) for a better glue feeding adjustment.
