The functions of the scissors on a ribbon weaving machine are mainly as follows:
- Cutting the Ribbon
- The scissors on the ribbon weaving machine are used to accurately cut the ribbon according to the set length or quantity. This enables the ribbon to be made into finished or semi-finished products with specific sizes, which is convenient for subsequent processing and use. For example, in garment production, the ribbon needs to be cut into appropriate lengths to be used as decorations for collars and cuffs or as belts. In the production of luggage, the ribbon is cut into specified lengths for making handles and straps.
- The scissors can also trim the excess parts of the ribbon, such as the burrs on the edge of the ribbon or the locally excessive parts caused by uneven tension during the ribbon production process, to ensure the overall neatness of the ribbon.
- Shaping the Ribbon
- By changing the knife molds of different shapes or adopting specific cutting methods, the scissors can cut the ribbon into various shapes. Straight knife cutting can produce ribbons with smooth edges; oblique knife cutting can make the edges of the ribbon inclined for special design requirements; and swallowtail cutting can make the end of the ribbon in a swallowtail shape, which enhances the decoration and uniqueness of the ribbon. This is often used in the processing of gift wrapping ribbons and clothing decoration ribbons to add a unique visual effect to the products.
- Edge Sealing
- The scissors of some ribbon weaving machines use technologies such as ultrasonic or thermal cutting to seal the cut edge of the ribbon while cutting it. The high-frequency vibration friction or thermal effect of ultrasonic waves melts and re-solidifies the fibers at the cut edge of the ribbon instantaneously, forming a sealed edge. This prevents the fibers at the cut edge of the ribbon from loosening and unraveling, improving the durability and stability of the ribbon. For example, in the application of ribbons for outdoor products, the ribbons with edge-sealed treatment can better resist the influence of the external environment and have a longer service life.
- Improving Production Efficiency
- The scissors of automatic ribbon weaving machines can work in coordination with the control system of the equipment to achieve functions such as automatic feeding and automatic cutting. This reduces manual operation links and labor intensity, and improves the degree of automation and production efficiency of ribbon production. For example, in large-scale ribbon production factories, multiple ribbon weaving machines with automatic scissors can operate simultaneously, which can quickly and efficiently complete the production of a large number of ribbons to meet market demand.
