  • the speed can be controllable at the writing position 300, and the web 302 can be accelerated or decelerated between the reading operations to adapt to the average speed of the web.
  • the acceleration and deceleration is of course not made only to read a magnetic field mark; the reading is normally associated to an operation 308 for finishing the packages, e.g. for the cutting of the web 302 into parts 310 and transporting 312 them to forming operations (not shown), as demonstrated above.
  • At least one of the magnetic field marks for each package to be formed can be positioned not more than 20 %, preferably between 5 and 15 % of the width of the material to form a package from a longitudinal edge of the material to form the package.
  • a magnetic field mark at such spots can then be used for controlling twisting of the material when forming the package.
  • the forming of the package is normally made by forming some kind of tube which then is sealed in some way at its ends and formed into the desired shape. The tube can then be unintentionally twisted, which can jeopardize the forming of the package.
  • such a magnetic field mark can help to control any twisting of the tube to ensure forming of the package.
  • the control is further enhanced since the reading of the magnetic field marks can be made from the side of the package where the joining takes place, which can be beneficial from a packaging machine design point of view, and also from the point of view that accuracy is improved if the position of measurement is fairly close to the position of the aligned operation.
