The REAL Carding Area Flats Cleaning Arrangement

- Active Flat Area The flats to be presented clean for every cycle is done by a unique aluminium extruded oscillating stripper with stationary
comb arrangement. Additional proven Philipson brush arrangement in the front ensures effective cleaning of flats.
The actual carding action takes place between revolving flats
and the cylinder. Card LC636 has 101 total flats out of which 36
Flats are in working position occupying 142 degrees of cylinder

Delivery Zone Energy Saving

Effective web transfer is ensured by saw tooth take-off roller and a pair of smooth web detaching delivery roller. The web is
collected by a pair of conveyor aprons, and the condensed web will pass through a pair of scanning rollers. Advanced timing Electrical System
belt drive ensures the machine’s quiet running even at higher delivery speed. Clearer brush located above the redirecting
roller strips the fiber from the redirecting roller during initial web piecing. The card LC636 has been designed and developed for lesser
energy consumption. The dynamically balanced carding
elements and energy efficient drives help in lesser power
utilization.

Electronically Controlled
Cylinder Brake System
The cylinder stoppages is carried out by Electronically
Controlled Cylinder Brake System. This helps in reduction
of machine downtime where cylinder stoppage is done for
carrying out any maintenance activity.
