Calendering :

Calendering is a process similar to ironing of fabric.  After damping the damped fabric passes through pairs of heavy rollers rendering threads in fabric flattened and improve the quality and appearance.

   
   
         


Lapping :


Lapping is the process in which Hessian fabrics are folded into the required size used in "Bale press" operation on the lapping machine.


Cutting
 :

Cutting is the process where the sacking cloth is cut to the required length for making bags for different size such as A-Twill bags and B-twill bags of 100 kg capacity.

   

 

   


Hemming :

In Hemming process, the raw edges of sacking cloth cut pieces are shown by folding it with sewing machine.

Herackele Sewing :

In Herackele sewing the sides of sacking cloth cut pieces are shown to make a complete bag.

Bailing :

Bags or Bale processing cloths are pressed compactly according to buyers need.
