<p>Respective secondary thrusters (70, 71) are added to the primary horizontal thruster (7) and primary vertical thruster (12) of a guiding device of the known type and the guide channel (6) is provided with dimensions such that the steps of guiding and feeding the capsule (C) are performed with minor successive displacements of the said capsule (C). The primary vertical thruster (12) operates, in a position distant from the sleeve (13) of the capping machine so as to allow discarding and free removal of the defective capsules (C) which have a double lid (C2) or the capsule parts which reach this thruster. The last section (206) of the guide channel (6) inside which the secondary vertical thruster (71) operates, has a width slightly smaller than that of the upstream section (106) of the said channel so as to retain firmly the end of the defective capsule (C) having lids (C2) on opposite ends of a base (C1). Such a defective capsule (C), which is arranged horizontally or inclined by the primary horizontal thruster (7), is then acted on by the tip (112) of the primary vertical thruster (12) and by a face (171) of the secondary vertical thruster (71) which discard this defective capsule (C) from the bottom of the guide channel (6). On the other hand, a capsule (C) correctly fitted with a lid (C2) and oriented vertically by the primary vertical thruster (12) remains inside the guide channel (6), is then displaced inside the latter by the secondary horizontal thruster (70) and then a leading face (271) of the secondary vertical thruster (71) acts on this capsule and accompanies the said capsule (C) during the complete stroke for insertion inside the sleeve (13) of the capping machine.</p> |
