A machine for gathering together the open end of a bag and applying an adhesive tape around the gathered neck includes a guide which receives the open end of the bag; a follow-up member 6 which, in response to a first sensor 4 detecting the presence of a bag, pushes the open end of the bag towards an adhesive tape 12 which is pulled by a gripper 15; a clamp 16, 17 to clamp the tape around the neck of the bag and a second sensor which detects the open end of the bag contacting the adhesive tape to control the gripper. The second sensor may operate by detecting the position of an arm controlling the follow-up member or else may comprise a pressure sensor monitoring the tension of the tape or a proximity sensor detecting the follow-up member or the bag itself. A third sensor controlling the gripper gripping the tape may also be provided. |
