Some FIBC designs use circular top or bottom panels that are joined to a tubular bag body, filling spout, or discharge component. Unlike standard length cutting, big-circle processing must also control the circular profile, center position, and material allowance around the edge.
The DYCBJ-1350 FIBC Cutting Machine provides a big-circle cutting range of 800–1260 mm for producing round top and bottom panels for different jumbo bag structures.
The circle diameter should not be determined from bag-body width alone. The bag structure, seam allowance, spout position, and subsequent sewing method must also be considered. Buyers should provide the required finished diameter, cutting diameter, and information about any center opening.
The PDF specifies a cutting accuracy of ±2 mm but does not provide a separate circularity or diameter tolerance. Trial cutting with the actual PP woven fabric is therefore required before batch production.
The machine uses pneumatic roll loading and handles fabric rolls with a maximum diameter of 1100 mm. Before the fabric enters the cutting section, automatic web guiding adjusts its lateral position. The listed correction distance is 300 mm.
Correct roll installation and alignment help retain sufficient material allowance around the large-circle layout. Continuous web deviation may affect the position of the circular profile across the 1350 mm-wide base fabric.
In addition to big-circle cutting, the DYCBJ-1350 can process square FIBC bottom panels and U-panel fabric. It also provides circular-hole and corner cutting within a 200–600 mm range.
Cold or hot cross-cutting is available, while forward-folding and forward-and-reverse-folding modules are optional. These functions should be configured according to the bag design rather than treated as one combined processing step.

This FIBC Cutting Machine is mainly used for cutting round top panels, round bottom panels, square bottom panels, and U-panel fabric for PP woven FIBCs and jumbo bags. The 800–1260 mm big-circle range covers different circular bag structures, while the 200–600 mm hole-cutting function can prepare drawing-defined filling or discharge openings. Final diameter, seam allowance, and opening position should follow the buyer’s bag drawing and approved trial sample.
The PDF’s 15–18 pieces/min rating applies to a reference cutting length of L=1000 mm and should not be interpreted directly as the big-circle cutting speed. Circle diameter, edge treatment, opening requirements, and material condition affect the actual cycle, which should be verified through product-specific trials.
The specified big-circle cutting range is 800–1260 mm. Diameters outside this range require confirmation of another machine or a customized solution.
Not necessarily. ±2 mm is the specified cutting accuracy, while the PDF does not state a separate circularity tolerance. Circular panels should be verified by trial cutting and measurement.
No. The supplied information also lists square FIBC bottom panels and U-panel fabric, along with cross-cutting, circular-hole cutting, and corner cutting functions.
