ABSTRACT:
A machine for making infusion bags and packaging them in respective envelopes, e.g. tea bag packages, and formed with the usual rotary head having radial arms for displacing the infusion bags after they are filled, is provided with a device for drawing the envelope strip from a roll thereof, folding it into a V as flanks of unequal length, cutting individual V-shaped sections from the folded strip to form wedges, and a pincer arrangement in which an inner pincer has a pair of fingers which grip each infusion bag, withdraw it from the respective radial arm and hold it until another pincer arrangement swings a respective wedge into a position in which its flanks straddle the bag and are engaged by an outer pair of fingers of the pincer assembly. The assembly of the bag and wedge are returned to the pincers of the arm.
