<p>1. Apparatus for the manufacture of sachet packs, in which a web (1) of packaging material is formed around a forming and filling tube (13) to give a tube (2) and the latter, after having been advanced by one sachet length each time, is severed by means of transverse seams into individual sachet packs (4), and which has an intermittently driven advancing device which comprises two continuous conveying means (20, 21) gripping the tube, and a traction means drive, of which one section of its traction means (40) runs between two wheels (43, 44) in the fixed position and loops around two drive wheels (34, 35) connected to the conveying means, characterised in that the conveying means (20, 21) together with their drive wheels (34, 35) are arranged to be adjustable relative to one another, and that one section of the traction means (40) is subdivided, by the drive wheels (34, 35), the wheels in a fixed position and deflection rollers (41, 42) associated with these drive wheels (34, 35), into three segments (45, 46, 47) which run parallel to one another and to the adjustment plane of the drive wheels.</p> |
