<p><P>PROBLEM TO BE SOLVED: To provide a continuous packaging machine capable of performing a packaging operation based on a sealing time by positively changing a packaging material feeding velocity, thereby capable of sealing the packaging material causing difficulty in sealing in a conventional manner, and to provide a paper feed control method and device for the continuous packaging machine. <P>SOLUTION: The paper feed velocity Vf for feeding the packaging material in the midst of a lateral sealing operation is set on the basis of a lateral sealing time Ts for the lateral sealing operation in one packaging cycle. The feed velocity Vf set for the lateral sealing time Ts is maintained with reference to a packaging material composed of the same raw material, even if the length of a bag is changed. For example, when forming a header on the continuous packaging bag, by changing the paper feed velocity within the remaining time of the one cycle, it is unnecessary to make a length required for the header longer, thus, the packaging material feeding velocity is reduced and the paper feed amount in one cycle is secured. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
