Abstract: Disclosed is an automated method (54) which includes directing rays from a source (34) to a tube (38) disposed between relatively movable first and second sealing plates (20, 32), capturing an image (70) of at least a portion of the tube (38) by an image capturing device (26), and transferring the captured image (70) to a processing device (24). The method (54) also includes determining a plurality of 26 tube parameters by the processing device (24) based on the captured image (70), using an image processing technique and determining a plurality of sealing parameters from a database (44) by the processing device (24) based on the determined plurality of tube parameters. Additionally, the method (54) includes controlling the drive unit (22) and a heater (36) by the processing device (24) influenced by the determined plurality of sealing parameters, to respectively compress the tube (36)and perform heat sealing of the tube (38).
