[0002] Knitted socks are a necessary commodity in daily life. After going through the production processes of knitting, sewing, shaping, etc., knitted socks need to be packaged before they can be circulated in the market. In the process of knitted sock packaging, paper cards of different sizes are used according to the thickness and width of the knitted socks. The paper cards are folded vertically once and horizontally twice to wrap single or multiple packages of knitted socks, and then the paper cards are taped together. This process is called waist sealing. The knitted socks after waist sealing are then bagged. Therefore, the waist seal of knitted socks is an important part of knitted sock packaging and determines the quality of knitted sock packaging.
