In the sack production line, this machine has the task of weaving the sack with the threads produced in the extruder. Some of the threads are placed in the machine as warp and some as weft, and by passing them through, the weaving process is done.

The woven product in this machine is round or tubular, which of course can be made into a layer by cutting one side. Garbage sack has the ability to easily form a bag by cutting the desired size and sewing the bottom, that's why it is the most widely used type of weaving machine in the bag weaving industry.

The circular weavers are divided according to characteristics such as the width of the sack they can produce, the number of shuttles, weaving speed, etc.
