GK35 Heavy Duty Bag Closing Machine

The GK35 Heavy Duty Bag Closing Machine is a specialised sewing unit designed to seal bulk bags containing commodities such as flour, grain, fertilizer and chemicals. It is available in several models - GK35‑2C, GK35‑6A, GK35‑6B, GK35‑8 and GK35‑8A - each featuring a single or double needle configuration with two or four threads respectively. All versions share an adjustable stitch length from 6.5 mm to 11 mm (standard setting 8 mm) and a maximum spindle speed of up to 2000 RPM, depending on material and operation. The machine dimensions are 500 × 500 × 325 mm and the weight ranges from 35 kg to 37 kg, packed in a carton.

The standard needle used is the 80800 series, size 200‑250 #, which is common for heavy‑duty bag sealing in the textile industry. Typical industrial installations employ a column and belt conveyor to feed bags, and the GK35 can be fitted with foot‑switch or photoswitch start‑stop controls as well as nibbler‑knife or air‑cylinder guillotine thread cutters. In the sector, a typical stitch length tolerance of ±0.2 mm and a standard thread tension range of 2‑5 N are required to achieve reliable seams on high‑density materials. Because the machine contains no electric components, it meets standard ex‑proof requirements for hazardous environments.
