Impianto pilota di spalmatura in continuo
Sistema modulare, intercambiabile, dotato di accessori completi, per
spalmatura da bobina a bobina, su fascia 250 mm. Gruppi di spalmatura
installabili: racla rotante, Meyer bar, coltello, lama d'aria; è anche previsto
un modulo di stampa flessografica ad 1 colore ed un gruppo di taglio a lamette,
con avvolgimento su 2 alberi. Consente di spalmare adesivi a solvente, ad acqua,
in hot melt.
It includes: Single unwinding unit, with mechanical brakes and manual
alignment set-up, by means of a pneumatic expansion shaft. Meyer-bar, with
coat width control edges and possibility to vary the feeding roll contact
angle by changing film feeding roll position. Alternatively you can install
a knife-over-roll coating module, for substrates requiring high viscosities.
This unit has a precise micrometric control of thickness and two side nylon
edges to control the coating width. Alternatively we can supply an air-knife
coating unit, suitable for high speed coating. 2 meter long drying oven,
electrically heated, with two independent heat regulations; materials lay on
free turning steel rolls. Driving and laminating unit, including a calender
with driving chrome treated cylinder and a free silicone rubber coated
cylinder. Additional unwinding unit, similar to 1) for liners or second
substrate feeding. Blade slitting unit, suitable for cutting 250 mm rolls
down to lower widths. A two frictioned driving shafts rewinder, allowing the
rewinding tension adjustment of coated materials and their collection on
both shafts, with two special rolls eliminating surface irregularities. We
can supply also a hot-melt coating device, based on a slot die applicator,
for the application of hot melt adhesives, eventually combined with the
application of water/solvent release agents. We can supply also a flexo-printing
unit for multi colours printing. We can easily make custom modifications to
the standard model.
