Bag Sewing Machines

High Speed Bag Closers and Bag Sewing Machines

Use a high-speed bag closer as a part of an automated bagging system. Pedestal mounted and portable bag sewing machines are also available.

Quickly close open mouth style bags (paper, plastic, polywoven, BOPP) in a bagging system. Bag sewing machines can be mounted over a conveyor or can be handheld for manually stitching or sewing shut sacks filled with products like feed, corn, nuts, rice, aggregate, and more.

An industrial high-speed bag closer on a conveyor usually sews bags shut at rates up to 20 bags per minute. A handheld bag sewing machine can close up to 8 bags per minute. Bag sewing machines can also be incorporated into larger packaging systems and combined with an automatic bag placer, bag top reformer, automatic tag placer, open mouth baggers, conveyors, or bag palletizing robots.

High-Speed Bag Closer Systems

High-speed bag closer system automatically closes 50 lb. open mouth bags.

These industrial bag sewing machines are incorporated into larger bagging operations and can sew up to 20 bags per minute. They sew shut multi-walled paper, woven, BOPP, and laminated woven polypropylene open mouth bags at medium to high speeds. The industrial sewing pedestals are manufactured to work with popular types of sewing heads from companies like Fischbein, Newlong Industrial, and Union Special. Start-Stop and thread / tape cutter photo eyes are standard and all pedestals are factory tested prior to shipping. Additional options include thread cutter controls, thread break detection kits, and high-speed power infeeds.

For fully automated bagging systems, we also recommend using an automatic bag top reformer. The bag top reformer is placed after the bagging machine and before the sewing pedestal. It automatically reforms the bag tops of flat, pillow type bags that can stand upright by themselves on a conveyor. The automatic bag top reformer can also be used with side gusseted bags. However, the fingers on the reformer will pull the gussets outward rather than inward.

Automatic tag placers are also used in automatic sewing bag closing systems. They can place and apply 3"x5", 3"x6", or 4"x6" tags that are sewn into each bag. Variable tag positioning is available through controller times.
