Description

Technical Field

[0001] The utility model relates to the field of non-woven fabrics, and more specifically, to a non-woven fabric slitting device. Background Art

[0002] Common non-woven fabrics are made of polyester fiber as the main raw material, and other fibers are added. Non-woven fabrics have the same advantages as ordinary cloth, such as softness, lightness, and good breathability, because it is a kind of fabric that does not need to be spun and woven. It is just that the textile short fibers or filaments are oriented or randomly arranged to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is not made of yarns interwoven and knitted together one by one, but the fibers are directly bonded together by physical methods.

[0003] At present, when non-woven fabrics are cut by slitting machines, the fabric in transit is rolled and cut by fixedly arranged cutters. If laser cutting is used, the cut edges can be smoother, but the power consumption is high and it is not convenient to adjust the cut width. If mechanical structures are used for cutting, burrs are likely to appear on the cut seams. Utility Model Content
