Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of weftless belt production, and particularly relates to a weftless belt equal-length slitting device. Background Art
[0002] Lapless tape is a continuous fiber composite material, usually made of alkali-free glass fiber yarn or similar high-strength fiber material impregnated with a specific resin (such as high-temperature resistant thermosetting unsaturated polyester resin). These fibers are arranged in parallel in the tape material without warp and weft interweaving, hence the name "lapless tape". It has good mechanical properties, such as high strength, high modulus and low elongation, and is widely used in electrical insulation, structural reinforcement and other fields. Lapless tape equal-length slitting device is a device specifically used to accurately cut continuous length lapless tape into equal-length segments. This type of device ensures that the length of the lapless tape cut each time is consistent to meet the requirements of dimensional accuracy in different applications.
[0003] The existing equal-length slitting device for non-weft tapes uses a slitting knife to cut. However, it cannot effectively limit the non-weft tape on both sides during the slitting process. The non-weft tape is easily offset during slitting, resulting in inaccurate cut length. The lack of lateral constraints may cause the cutting position to be non-vertical and the edge to be uneven, affecting the use effect and aesthetics of the non-weft tape. Utility Model Content
