Bag closing systems - Import export

The high-performance sewing machine from STATEC BINDER stands for precise and reliable bag sealing of woven PP, paper or PE bags. Two different variants can be used for sewing the bags. On the one hand there is the straight-line bag infeed, in which the bag is fed to the sewing head by means of a belt drive and then sewn at the upper end. The second variant is the bag edge folding, in which the bag is folded at the upper end when it is pulled in and then sewn. In order to change from one system to the other, it is only necessary to replace a simple device. The bag to be sewn is fed to the sewing machine via one of the two variants mentioned above. Depending on the sewing speed and performance, the stitch length is between 7 and 12 mm. A cutter at the end cuts the thread. The sewing head is driven by a motor with frequency converter. A big advantage over the drive via belt pulleys is a more precise adjustment of the speed.

The patented bag closing system “Over Tape Bag Sealer” from STATEC BINDER seals woven polypropylene (PP) bags airtight. A woven PP tape is used for a reliable and secure closure. If necessary, the bags can also be sewn. Both pillow bags and gusset bags can be securely closed. This sealing technology facilitates the handling of dusty and odour-intensive products of the food and feed industry. During operation, the filled bags are transported to and from the bag closing system via a conveyor belt. A sensor detects the position of the bag and automatically puts it into the trimming area. After cutting the top edge of the bag a woven PP tape is applied over the open edge of the bag to seal it with hot air. The hot air to seal the bag airtight and odourless is produced by a heating unit in the machine.
