发明名称 Method and apparatus for forming an article having a securely-attached string
摘要 A method and apparatus is disclosed for forming an article such as a tampon having a securely attached string. The method includes intermittently feeding filler members into one end of a hollow tube which is open at both ends. A sheet of heat sealable material is advanced towards the tube and folded so as to cylindrically wrap about the tube. The abutting edges of the material are fused together to form a cylindrical casing into which the filler members enter upon exiting the tube. Apertures are then transversely formed in the casing between the adjacent filler members and a string is inserted through the apertures. The casing is then heated and compressed against the string to form a permanent bond. After the bond is formed, the casing is severed to form individual articles which are sealed at both ends and have a string attached to one of the ends.
