摘要
Filter bags containing a substance from which to prepare an infusion are fashioned from tubular blanks of filter paper having an elongated appearance, each one filled with measured and separate quantities of the substance distributed along its length, which are doubled up and made secure, then provided with a label attached by a length of thread. A machine for automating the manufacture of such bags includes a wheel carrying grippers with radial arms, around which the thread is drawn peripherally as the grippers are indexed in turn through a station where the blank is folded double initially, a forming station at which the two joined ends are folded together to effect a closure, a cutting station at which the thread is divided into single lengths, a feed station supplying the labels, and a fastening station at which the length of thread is knotted both to the label and to the closure.
