Jute machines
Step 1: Softening
Jute softener
Fluted rollers that crush and bend raw jute while it is sprayed with water and oil emulsion, making the fibre soft and supple.

Request this machineStep 2: Carding
Breaker card
A large cylinder with pins that tears the softened jute into finer fibres and forms a loose sliver.

Finisher card
A finer card that opens the sliver further and blends it into a more even ribbon of fibre.

Request this machineStep 3: Drawing
Drawing frame
Combines several slivers and draws them out between gill pins, so the sliver becomes even and the fibres lie parallel.

Spinning frame
Draws the sliver thinner and twists it into jute yarn on rows of flyers.

Spool winder
Winds yarn from spinning bobbins onto large spools for the warp.

How a jute mill works
The main steps from raw jute to yarn, hessian and sacking, and the type of machine that usually does each one. Spinning mills stop at the yarn.
Softening
Raw jute is opened and passed through fluted rollers while water and oil are added, so the fibre turns soft and supple.
Machines at this step: Jute softener
Carding
Carding machines split and straighten the fibres and form them into a continuous ribbon called sliver.
Machines at this step: Breaker card, Finisher card
Drawing
Several slivers are combined and drawn out so the ribbon becomes thinner and more even.
Machines at this step: Drawing frame
Winding
Yarn for the warp is wound onto spools and yarn for the weft onto cops, ready for the loom.
Machines at this step: Spool winder, Cop winder
Weaving
Looms weave the yarn into hessian, sacking and other jute cloth.
Machines at this step: Jute loom
Finishing and bag making
Cloth is pressed smooth, cut and sewn into sacks and bags, then pressed into bales for shipping.
Machines at this step: Calender, Bag sewing machine, Baling press
