ABSTRACT:
A process and apparatus are described for producing drawstring packets. The packets are produced by forming thread loops (L) with tags (T) attached to their ends and placing the packet web material (W) onto the portions of a the loops further from the tags. After securing the loops in their shaped form temporarily to one face of the web, the tags and the remaining portions of thread are placed on the other face of the web to be attached there releasably. In subsequent processing the secured loop portions lie inside the packets and the tags outside. The process allows relatively precise location of the loops so that packets can be produced with the loops in a peripheral channel (P) sealed from the contents of the packets but able to move to contract the package when the ends of the loop are pulled.
