Configuration Selecta and Ariosa T3

Main features
  • Steel basement structure to give lifetime stability;
  • Buffing roller manufactured with techniques that ensure perfect balance;
  • Buffing roller predisposed for the air or water cooling systems;
  • Rubber transport roller having a range of rubber types and hardness to be chosen in cooperation with the customer in order to suit any type of buffing operation;
  • Independent adjustment of the thickness on the left and right sides of the machine allowing to give more pressure on one side or the other;
  • Manually operated holding blade (standard) or automatically operated through a photocell (optional) to buff the leather till its final edge;
  • All motors are controlled by inverter and all the speeds are visualized onto dedicated displays;
  • Leather exit conveyor with widening belts to be connected to the dedusting machine;
Optional accessories on request
  • Spreader, feeding conveyor for soft leathers;
  • Manually controlled buffing increment device to increase the buffing action onto specific areas of the leather;
  • Motorized holding roller to ease the feeding of soft leathers;
  • Pneumatic holding blade automatically controlled by a photocell to buff the leathers even in the final part;
  • Ionizing bar to reduce electrostatic charges;
  • Variable speed of buffing roller. Essential  for specific  processes like nubuck, snuffing, recovery of previously finished leathers etc..
  • Water cooling system closed circuit of the buffing roller with stainless steel tank and radiator for a greater save of buffing paper and a longer duration of the rubber transport roller. The water cooling system allows to avoid vibrations that creates the “chatter marks” prevents the buffing paper from melting while processing greased leathers and avoids alterations of the colours of splits and suedes;
  • Water cooling system with stainless steel tank and chiller is normally used in tropical countries or when the machines are working in a continuous loop
  • Leather exit conveyor with divaricated belts and with bar-leather-straightening device, or with helical- rotating-roller, or helical-rotating-roller and discs widening conveyor (only for models 3200 and 3400);
  • Aspiration under exit conveyor (up to 2100 model)
  • Rubber sleeve changing device;
  • 4.0 version controlled by PLC and touch screen control panel for the automation of several machine’s functions;
  • Remote assistance and troubleshooting;
  • Motorised adjustment of the working thickness
