PURPOSE:To form lateral adhesion parts accurately at specified intervals even in the case where intervals of the lateral adhesion parts are varied when sealed bag-like packaged articles are produced continuously by forming vertical adhesion parts continuously on a belt-like film material with a hot roll and forming the lateral adhesion parts at predetermined intervals with a hot press and a cooling press. CONSTITUTION:The longitudinal size of an article 4 to be packaged is converted into the number of pulses by an electronic type control unit 26, while the number of rotations of a hot roll, 11 is converted into the number of pulses by a pulse generator 18 and these numbers of pulses are compared with each other by a comparator 27, whereby a rotation start signal is sent to a rotational speed variable setter 28 from which an operation signal based on an operation condition sent from the electronic type control unit 26 is given to a rotation controller 22 for a hot press 13. Further, on the basis of rotation start timing instruction data sent from the electronic type control unit 26 to the rotational speed variable setter 28, the same operation signal as the operation condition of the hot press 13 is given to a rotation controller 25 for a cooling press 15. |
