What Is a Bag Stitch Machine?
A Bag Stitch Machine is a specialized sewing machine for industrial use that can sew a bag with a single operation.
There are also hand-type sewing machines mainly used in the field, stationary machines that can measure the load while sewing, and convenient machines that can attach tags and labels on the workbench. There are one-thread and two-thread setting types, with the difference being in strength created by the seam allowance of the back thread.
Uses of Bag Stitch Machines
The main applications are feed and grain bags in the agricultural and livestock sector; they are used for sewing the mouths of jute bags weighing 30 kg to 50 kg and polyester material after filling.
Familiar examples include the well-known paper-made 30 kg rice bags. It is also used for coffee bean bags made of jute.
Other applications include sewing artificial lawns, free stitching of canvas, and temporary repair of tents, taking advantage of the freedom of mobility.
Principle of Bag Stitch Machine
The characteristics of sewing machines are generally divided into large hand sewing machine types and tabletop sewing machine types. Depending on the sewing capacity and application, there is a single-thread type that can also be used for back stitching with one front thread, and a double-thread type that can create a double chain for each of the front and back threads.
The hand-sewing machine type is popular for its portable convenience. When you want to inspect the contents of a loaded bag, you can close the opening again without unloading the bag. You can handle the equipment at any angle you want without the need to move the cargo.
Both single-thread and double-thread types are available. There are also high-end models on the market that are capable of sewing thick jute bags of coffee beans.
Bag Stitch Machines with a loading platform or tabletop are suitable for weighing and inspecting loads. They are attractive for sewing labels and tags at the same time. The stability of the machine makes it suitable for sewing products that require a beautiful seam allowance and for large-volume sewing work that requires accuracy.
