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.
