In this machine, a continuously moving tubular web is cut to form tubular pieces of equal size which in each case contain two portions of tea, these pieces being passed with the aid of a continuously rotating transport wheel 10 to various work stations in which first of all the bag bottom is formed and then the tubular piece 15, folded in a W shape by drawing the bag bottom into the interior of the transport wheel, is sealed by folding the head to give a double-chamber bag, there extending at the level of the circumferential plane of the transport wheel 10 a cover 20 which, together with a pair of arms 21, 22 fastened pivotably on the transport wheel, ensures precise fixing and positioning of the tubular piece during the entire production process, and at the same time the open ends of the tubular piece are bound in such a manner that the tea is at no time able to scatter into the tabs 15c, 15d provided for forming the head fold (Fig. 2). …<IMAGE>… |
