ABSTRACT:
An apparatus with a rotary wheel for applying, to a flattened tube of thermally weldable filter paper forming dual-use filter sachets having multiple bags or pouches defined serially by transverse thermal welds in machines for continuously producing the filter sachets, labels spaced relative to the transverse median line of the alternate transverse thermal welds, as well as a longitudinal thread transversely on the labels and thermally weldable stickers or tabs across these alternate transverse therman welds. The rotary wheel had a plurality of equidistantly spaced heads comprising heating elements as well as pickup and infeed elements for the labels, the thread and the tabs, and further a plurality of devices with pincer elements interposed between the heads designed to fold the thread in a loop. Pressure pad elements cooperate in counter-rotation of the heads.
