Abstract
Tags and thread are assembled together for the manufacture of tagged articles such as infusion packets in which each tag is attached to the packet by a length of thread. The thread is held in a looped form between the tag and the packet before use. For the assembly of the tags and thread and to increase the length of thread attaching each tag, means are provided for forming a doubled-over loop that can be trapped between the tag and the packet.
Claims14
Apparatus for producing an assembly of tags and thread with a web in which the tags are located at spaced intervals along the length of the web with a length of attaching thread between each successive pair of tags having a length greater than the spacing between the tags, the apparatus comprising means for forming the thread between the tags into loops, means engageable with the thread loops so formed for doubling over said loops, and for locating the doubled loops at least partially against the tags and means for bringing the web and tags together with said loops between them to hold the loops releasably in said doubled form.
A method of assembling a series of tags at spaced intervals along the length of a web with an attaching thread for securing each tag to the web, in which the thread is formed into loops between the tags whereby the thread between the tags has a length greater than the tag spacing, and said loops are doubled over and are located at least partially between the tags and the web to hold them releasably in said doubled form.
