Buffing Machines

Innova

Through-feed buffing machine

After the years of experience matured with the SELECTA, it was still difficult to manage short and small sized leathers in their passage from the buffing machine to the dedusting one, because these leathers always fell on the exit conveyor and folded themselves. To solve this problem we have manufactured the INNOVA, a machine with the same characteristics than the SELECTA except for the frame that is no longer at 90° but is inclined at 45°. This solution permitted to reduce the distance between the buffing roller and the exit conveyor so that the leathers exit perfectly laid out from the buffing machine.
Among the strong points of Innova we have:

The finer and evenly cutting of the fibres;
The reduced distance between the cutting point and the leather exit point that grants a linear passage of the leather from the buffing roller to the exit conveyor with the leather being perfectly laid out and with less tensioning compared to any other machine. This difference is more noticeable with the short leathers as croupons and sheep and goat skins.

Indicative Technical Data

Configuration of Innova and Ariosa T4

Main Features
  • Steel basement structure to give lifetime stability;
  • Buffing roller manufactured with techniques that ensure the perfect balance
  • Buffing roller predisposed for air or water cooling
  • 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
