Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for through-thread threads. Background Technology

[0002] The warp thread is one of the components used in jacquard machines to control the warp yarns. During operation, it is often subjected to friction, causing wear and tear. It needs to be replaced to prevent breakage and affect processing. Generally, the warp thread is cut to the appropriate length before installation. However, it is easy to cut too much or too little, making it difficult to cut to the appropriate length. The length needs to be measured and marked in advance to achieve the correct size. During the cutting process, the warp thread is prone to moving around, causing the cutting to be skewed. Therefore, a warp thread cutting device is proposed. Utility Model Content
