Abstract
An apparatus for preparing and feeding materials used to make a filter bag for infusion products includes a revolving wheel having mechanisms arranged in succession thereon that are used for: forming filter bag pick-up tags and arranging them in order; feeding a continuous thread and forming first loops in the thread at regular intervals; delimiting separate faces on the tags and folding them onto each other so that the loops are held therebetween; joining the faces of each tag to each other; associating a web of filter paper to the edge of the revolving wheel and positioning it above the continuous thread and the tags connected to the thread; pushing a portion of the thread through the filter paper so as to form a second loop extending outward from the wheel.
