description

Card feeding system designed to maximise fibre density control both longitudinally and across the whole machine width, thus optimising the quality and efficiency of the following carding phase. The fibre compacting pressure is kept under tight control by means of independently adjustable pressure switches, one assembled on the top and one on the bottom chamber, both working within very narrow pressure value variation. The fibres are accurately opened and laid down so as to create a homogenous fibre lap, thanks to a specially controlled air system.

technical data

  • Working width: 1000 to 5000 mm (other options available upon request)
  • Weight range: Up to 3,000 g/square m. (other options available upon request)
  • STAINLESS STEEL inner chamber structure
  • Top chamber with fixed walls and inspection window
  • Ducting and controlled suction of the air in excess
  • Feed rollers
  • Opening roller with hardened steel pins
  • Bottom chamber with fixed walls and inspection window
  • Grooved discharge rollers, with adjustable distance
  • Pressure switch on the fibre feed channel, to control fibre feed quantity
  • Differential pressure switch assembled on the bottom chamber, to control fibre filling and the homogenous distribution of the same

details

Continuous weighing system of the delivered lap of fibres

A loading cells system is assembled for accurate and continuous weight control of the fibre lap being delivered by the feed tower.

fibre lap

The the fibre lap being delivered by the machine is perfectly homogenous, both longitudinally and crosswise on the whole working width of the machine.

Dynamic pressure control system

Thanks to a computerised air supply and pressure setting control in the top and bottom chambers, the machine allows an accurate control of the fibre density across the whole width, thus guaranteeing a perfect uniformity of the fibre lap being fed to the card.
