Title:
METHOD FOR MANUFACTURING FOLDED TEA BAG STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/057907
Kind Code:
A1
Abstract:
A method for manufacturing a folded tea bag structure, comprising a stacking step (112) and a crimping step (113). The stacking step (112) causes a sheet (1) having a folded line to be in a stacked shape and to join two opposite side edges of the sheet together; and the crimping step stretches the sheet (1) into a hollow cylindrical shape, and folds and presses the sheet (1) along the folded line (21) into a cylindrical folded structure having two open ends (101, 102). After the folded tea bag structure (10) is formed, one end of the folded tea bag structure (10) is closed; and then after tea leaves are filled, the other end of the folded tea bag structure (10) is closed. Such an arrangement in conjunction with a mechanical device can complete the production process in an automated or semi-automated manner, increasing manufacturing efficiency.
