Basic Principles of Using Small Fasteners
The fastening operation of a slitting warp machine is similar to braiding hair, requiring precise calculation of the position of each warp yarn. The function of the small fasteners is to fix the warp yarn density, ensuring uniform tension during weaving. The calculation needs to consider the total number of warp yarns, the strip width, and the machine model. Typically, the number of fasteners per centimeter = total number of warp yarns ÷ (strip width × number of strips).
Three Steps to Master Threading Calculation
Measure Strip Parameters: Measure the actual width of the working strip using a ruler (unit: cm).
Confirm Total Warp Count: Check the process sheet or directly count the number of warp beams on the bobbins.
Calculate using the formula: Number of threads per strip = Number of warp yarns ÷ (Strip width × 0.8), where 0.8 is a common correction factor.
Practical Tips to Improve Efficiency
Use colored marking tape to distinguish different strips and avoid threading errors.
Thread the middle thread first and then expand to both sides to reduce cumulative errors.
Regularly check the wear of steel buckles; replace them promptly if deformation exceeds 0.1mm.
New workers can use a mobile calculator app for assistance; input parameters and the app will automatically generate results.
