BASIC EQUIPMENT:

Pleating machine for minipleat provided with:

• Marking roller group composed by marking shaped steel blades and elastomer anvil.
• Dragging roller group completely covered with elastomer.
• Roller group for pleat heights from 20 up to 180 m/m, by increasing 1 m/m each time from 20 to 60 m/m, 2 mm each time from 60 to 120 m/m and 4 mm each time from 120 to 180 m/m. The change of pleat height is made by substituting a gear on the marking roller. This substitution allows the changing of speed ratio between marking and packing rollers.
  • I.e. by assembling a 48 teeth gear, on marking roller, a 48 m/m pleat height is obtained.
• Pressure control on marking rollers by thickness gauge with micrometric screw adjustment ; successively it is possible to verify through a dial gauge on request.
• Paper sliding cylinders: light adjustment during the assembly phase with the exception of the bottom roller, by different and well defined positions according to the cooling of hot-melt adhesive.
• Speed adjustment of the collection layer by inverter with its potentiometer.
• Adjustment of the vertical and horizontal positions of the collection layer by manually controlled screws.
• Folds marking system composed by an automatic pneumatic control airbrush and an electronic impulse counter.
• Pleat distance is constant thanks to the application of Hot-Melt bands on both sides of the pleated filter element.
• Electronic control speed variator.
• Reel holder for reels max Ø 1000 m/m characterized by idle unwinding with loop control through photocell.
• On request fast reel substitution system.
• Longitudinal cutting group composed by 3 couples of blades of whom n° 2 hatched and n° 1 continuous.
• Conveyor belt composed by an electro-welded metal frame and by a conveyor motorized layer, with adjustable speed synchronous to the speed of the pleating machine; the group is assembled on adjustable feet for the correct levelling of the machine to the paper outlet table.
• N° 2 Hot-Melt dispensers composed by a melting and a pumping units: gear pump; continuous current engine; PTFE coated ant adherent tank and new technology without melting fumes, 18 litres, fast unloading, melting capacity with EVA adhesives from 1200 mps at 160°C of 13 kg/h, with sequential heating; automatic protection against over temperature; temperature adjustment of the manifold tank; 99 programs to be memorized, distribution program of glue by drops, starting and final correction program of the glue distribution, glue distribution control by encoder and timer; no. 2 dispensing guns at 21 modules, axle base 30 m/m, with no. 4 solenoid valves, filter and connection; no. 8 thermo regulated tubes; n° 1 encoder.
• Hot-melt nozzles assembled on adjustable holder in height and depth.
• Manual cut of filter packs.

TECHNICAL DATA:

• Working width: 930 m/m about
• Adjustable speed by inverter from 80 up to 250 pleats/minute, according to the pleat height: indicatively, with a 50 mm pleat height, speed is about 80 pleats/minute, whereas with a pleat height of 25 mm, speed increases up to 250 pleats/minute.
• Pneumatic installation: 6 bar.
• Electric installation: 380 V, 3 phases, 50 Hz, auxiliary voltage 24 V.
• Installed power: 1,5 Kw about (hot-melt dispensers excluded).
• In conformity with CEE Directives 89/392, 91/368, 93/44, 93/68.
• Technical annexes: declaration of conformity according to the "Machine regulation" 89/392-CE in force, manual of instructions and maintenance complete with electric and pneumatic diagrams, CE marking according to the "Machine regulation" 89/392-CE in force.
