Abstract:
1. A folding machine with a collect run mode, having a cutting cylinder equipped with cutting blades for cutting a paper web to give cut paper, a folding cylinder provided next to the cutting cylinder and provided with an odd number of pins for holding the cut paper positioned at equal distances along the direction of the peripheral surface of the folding cylinder surface and an odd number of folding blades are provided with ends projecting slightly from a surface of the folding cylinder surface positioned at a central part of the held cutting paper, and positioned at equal distances along the direction of the peripheral surface of the folding cylinder surface, a jaw cylinder next to the folding cylinder provided with a jaw mechanism for holding and supporting a central part of the cut paper made to project by a folding blade, and being capable of switching between a straight run where the jaw cylinder sequentially supports the cut paper and the cut paper is folded and a collect run where two pieces of the cut paper are sequentially overlaid by the folding cylinder and the jaw cylinder sequentially supports and then folds the two overlaid pieces of cut paper, said folding machine with collect run mode comprising: folding cylinder fixed cam means having a folding cylinder fixed cam of a cam shape for making the pins of the folding cylinder perform a straight run delivery operation; folding cylinder rotating cam means having a folding cylinder rotating cam that rotates separately from the rotation of the folding cylinder, and is provided with covering sections capable of covering a cam shape capable of carrying out a straight run delivery operation of the folding cylinder cam by rotational displacement; jaw cylinder fixed cam means having ajar cylinder fixed cam of a cam shape for making the jaw mechanism of the jaw cylinder perform a straight run delivery operation; jaw cylinder rotating cam means having a jaw cylinder rotating cam that rotates separately from the rotation of the jaw cylinder, and is provided with covering sections capable of covering a cam shape capable of carrying out a straight run delivery operation of the jaw cylinder cam by rotational displacement; drive transmission means capable of providing rotational drive simultaneously to the folding cylinder rotating cain means and the jaw cylinder rotating cam means in order to cause the covering sections of the folding cylinder rotating cam means to rotate at a predetermined rotational speed ratio with respect to rotation of the folding cylinder, and cause the covering sections of the jaw cylinder rotating cam means to rotate at a predetermined rotational speed ratio with respect to rotation of the jaw cylinder; and switching means for switching drive transmission over between the folding cylinder rotating cam means and the jaw cylinder rotating cam means, wherein an all of the jaw mechanisms operate at the same frequency without exception during collect run mode.
