Abstract
A machine for making filter bags for infusion products includes a first carousel for continuous rotary movement about a first axis and having first operating stations movable therewith, each first operating station configured to operate on a corresponding piece of filter material fed along an angular stretch of the first carousel, to lift two chambers to a position side by side. A second carousel positioned alongside the first carousel and rotating continuously about a second axis parallel to the first axis has a plurality of joining elements positioned along, and continuously movable with, the second carousel. Each joining element is connected to corresponding control devices for actuating, in a synchronized fashion, a succession of movements of the joining element to intercept free ends of erect filter material, positioned on an operating station and joining them, towards one of the two chambers containing a dose of product.
