When the roll paper is attached and the paper is spliced in No. 1, (1) If the arms 4a and 4b are in the operating position R, for example,
One paper roll support shaft 5a ₁5b₁Rotate and rewind
Holding the paper roll that is performing ₂5,
b₂Has come to the position L of the paper winding device.

On the other hand, the maximum width and the minimum width of the paper roll to be loaded are divided into a plurality of sections (for example, the maximum width to the intermediate width and the intermediate width to the minimum width). Depending on the web width of the range, the side ends on the web side of the pair of arms 4a, 4b are the same number as the above-mentioned number, and are spaced by a certain distance on the spindle 3 to serve as a reference in the width direction of the rotary press. The pair of arms 4 is rotated by turning the pinions 10a and 10b so as to match one of the lines on the T side and the S side that are marked on the position calculated by the machine center (hereinafter referred to as the center of the web width).
Move a and 4b. (2) At this time, since the space between the pair of arms 4a and 4b which has moved to the ruled line position corresponding to the roll width section is opened more than the roll width, the roll paper is inserted between the arms 4a and 4b. The paper tube on the side of the paper roll T side is inserted into the taper cone (chuck cone) of the paper roll support shaft 5a. At this time, the web support shaft 5a ₁ is moved by the drive device 14 so that the end on the T side of the paper roll comes to the position of the distance L ₁ set (calculated from the center of the width of the web press) from the end on the paper web side of the arm 4a. . This moving position is determined by the moving distance L ₂ from the tip of the taper cone of the paper roll support shaft 5a _{1 to} the end of the arm 4a on the paper roll side, and this moving distance L ₂ is attached to the shaft end of the pinion shaft of the drive unit 14.

_When inserted in ₁ , the support shaft 5b ₁ is pushed into the paper tube via the bearing 15 by the air cylinder 16, and the roll paper is chucked (mounted). (4) The preceding web is then consumed for printing,
When the diameter becomes equal to or less than the specified value, the turning paper supported by the take-up paper supporting device is about 150 by the turning device 6.
It rotates to move to the paster position P corresponding to the diameter of the paper roll. At this time, the diameter of the web is detected by this rotational position, and the web accelerating device 17 accelerates the web to the same peripheral speed as the web speed of the preceding web. At the same peripheral speed, the web is lowered to a fixed splicing position. Paper splicing device 26
Paper splicing is performed by. After the paper is spliced, the arms 4a and 4b are further rotated to move to a fixed operating position R where the position does not change.

[0009]

The paper feeding section of the conventional rotary press shown in FIGS. 12 to 14 has the following problems. (1) When the position of the end of the T-side arm 4a of the paper roll on the side of the paper roll is determined and mounted, the weight of the paper roll is as heavy as about 1 ton. Therefore, the main shaft 3 bends slightly, and the main shaft 3 and the arm reach the diameter of the paper roll. depending rotates back and forth 150 degrees from the paper roll support position, when rotated in the paster position, the determined position of T-arm side end of the web is shifted, moving the reel supporting shaft 5a ₁ of the T-side arm 4a The position of the T-side arm side end of the paper roll must be adjusted. (2) The T-side arm 4a and the S-side arm 4b and the turning device 6 for rotating these arms 4a, 4b must be provided. Also, the paper roll support shaft 5 of the T-side arm 4a
