  "abstract": "In the case where the width of a web roll for the next job is much different from that of the web roll for the former job, the rotational position of the new web roll is moved to a position at which a web of the new roll is easily pasted to the web of the old roll and the new web roll is held at the position. A device for continuously supplying a web can continuously supply the web by adhering the web of an old web roll onto the web of the new web roll. The device includes a manual paper paster setting means for setting a manual paper paster mode and a control device for locating/stopping the rotational position of the new web roll at an adhering waiting position in response to a signal from the manual paper paster setting means.",
  "claims": [
    "1. A method for controlling a device for continuously supplying a web by adhering a web of an old web roll onto a web of a new web roll, said method comprising: moving said new web roll into proximity with said web of the old web roll; and controlling the rotational position of said new web roll about its axis said new web roll such that the leading edge of said new web roll is at an adhering waiting position in response to a signal from a manual paper pasting setting means for setting a manual paper pasting mode.",
    "2. A method for controlling a device for continuously supplying a web as claimed in claim 1, said method further comprising: switching on said manual paper pasting setting means under a condition in which an automatic paper pasting operation is likely to cause problems, including when the width of said web of said new web roll is narrower/wider than the width of said web of said old web roll.",
    "3. A method for controlling a device for continuously supplying a web as claimed in claim 1, said method further comprising: adhering the web of said old web roll onto the web of said new web roll in response to a signal from a switch for adhering the web of said old web roll onto the web of said new web roll.",
    "4. A method for controlling a device for continuously supplying a web as claimed in claim 3, said method further comprising: cutting the web being unwound from said old web roll in response to a signal from a switch for cutting the web being unwound from said old web roll.",
    "5. A method for controlling a device for continuously supplying a web as claimed in claim 1, said method further comprising: switching on said manual paper pasting setting means under a condition in which an automatic paper pasting operation is likely to cause problems, including when a material of said web of said new web roll is different from a material of said web of said old web roll.",
    "6. A device for controlling a device for continuously supplying a web by adhering a web of an old web roll onto a web of a new web roll, said device comprising: a first driving means for moving said new web roll into proximity with said web of the old web roll; a second driving means for controlling the rotational position of said new web roll about its axis such; means for setting a manual paper pasting mode; and a control device for stopping said second driving means at a rotational position of said new web roll such that the leading edge of said new web roll is at an adhering waiting position in response to a signal from said means for setting a manual paper pasting mode.",
    "7. A device for controlling a device for continuously supplying a web as claimed in claim 6, said device further comprising: a switch for adhering the web of said old web roll onto the web of said new web roll; and means for adhering the web of said old web roll onto the web of said new web roll in response to a signal from said switch.",
    "8. A control device for controlling a device for continuously supplying a web as claimed in claim 7, said control device further comprising: a switch for cutting the web being unwound from said old web roll; and means for cutting the web being unwound from said old web roll in response to a signal from said switch.",
    "9. A method for controlling a device for continuously supplying a web as claimed in one of claim 1, claim 2 and claim 5, said method further comprising: reducing the rotational speed of a printing press in response to said signal from said manual paper pasting setting means."
