Title:
METHOD AND DEVICE FOR GLUING LONGITUDINAL SEAM ON CYLINDRICAL BAG BODY, AND FILTERING BAG
Document Type and Number:
WIPO Patent Application WO/2019/137417
Kind Code:
A1
Abstract:
A dust removal filtering bag with a glued longitudinal seam and a method for processing a longitudinal seam on a cylindrical body of the dust removal filtering bag. A glue is applied on mutual contact surfaces where two sides of a filtering cloth are overlapped and bonded together for gluing to form a cylindrical bag body. Furthermore, a matching device is provided. By means of a combined processing approach of gluing and sewing, the problem of cloth seam dust leakage at a longitudinal seam on a cylindrical bag body and needle hole dust leakage caused by sewing can be solved while manufacturing the cylindrical bag body, thereby improving the dust removal performance of a dust removal filtering bag.
