Description

Technical Field

[0001] The invention relates to the technical field of paper bobbin manufacturing, in particular to a method for manufacturing a paper conical bobbin. Background Art

[0002] The bobbin, also called the weft tube, is mainly used on the shuttle of the shuttle loom. The bobbin used is different for different shuttles. The material is generally plastic, with no core shuttle bobbin, and the bobbin specifications are relatively many. In addition, the shuttle length is generally different, the bobbin length is also different, and the same length of shuttle has different sets and different bobs. Users should choose the bobbin according to the shuttle used. There are many types of bobbins now, including wooden and paper bobbins. Among them, the manufacturing technology of paper tubes is becoming more and more mature, its manufacturing quality is constantly improving, the cost is low, and it is increasingly widely used.
