点があつた。(Prior Art) FIG. 1 shows a first comparative example of the conventional art, in which a base paper 5 is made into a plate in a plate-making section 2, and is gradually fed by a feed roller 3, and its leading end is clamped by a clamper 4 of a plate cylinder 1. The plate cylinder 1 is wound by rotating at a very low speed in the direction of the arrow, but in order to do so, the plate cylinder 1 must be rotated uniformly at about 1 rpm. However, in general, the plate cylinder is connected to an interlocking mechanism such as a cam, and the load fluctuates greatly during one rotation, making it difficult to obtain a uniform and accurate ultra-low speed.If uneven rotation occurs, the load increases on the base paper and plate making This method had the disadvantage of causing a decline in quality and damage to the base paper.

手段（図示なし）を有している。(Structure) FIG. 3 shows an embodiment of the present invention. Plate making department 20
A base paper feed roller 2 is installed in the base paper conveyance path between the plate cylinder 21 and the plate cylinder 21.
2 and a base paper discharge roller 23 having a one-way clutch are disposed, and an opening/closing guide plate 25 is provided between both rollers 22 and 23, with one end pivotally connected to a pin 24 so as to be able to rotate downward. 26 is the plate cylinder 21
The clamp unit 27 is a clamp detection sensor that detects when the leading end of the base paper 28 is inserted into the clamp unit 26 and is clamped. Upon detection by the clamp detection sensor 27, a clutch (not shown) connected to the base paper discharge roller 23 is activated. Cutting, base paper ejection roller 23
It is now possible to stop the 29 is a base paper drive motor. In response to the output of the detection means, the drive of the discharge roller 23 is stopped, and the drive of the base paper feed roller 22 is continued for a predetermined period of time, thereby forming a slack in the base paper between the base paper discharge roller 23 and the base paper feed roller 22. After the predetermined period of time has elapsed, the plate cylinder 21 is rotated, and the base paper discharge roller 23 having the one-way clutch is rotated loosely, thereby winding up the slack base paper (not shown).

い。 Next, the effect will be explained. After the base paper 28 is made into a plate in the plate making section 20, it is sent to the base paper feed roller 22 and further advances. At this time, the guide plate 25 is in the horizontal position indicated by the solid line and is closed. The base paper 28 passes over this opening/closing guide plate 25 and passes through the base paper ejection roller 23.
The tip is inserted into the clamp portion 26 and clamped. The clamp detection sensor 27 detects this, and a clutch (not shown) connected to the base paper discharge roller 23 is disengaged, and the base paper discharge roller 23 stops. At the same time, the opening/closing guide 25 is opened downward to the position indicated by the two-dot chain line by a solenoid or the like. When the base paper feed roller 22 is driven in this state for a predetermined period of time, the base paper 28 forms a downward slack as shown by a two-dot chain line. When the plate making is completed after a predetermined period of time has elapsed, the base paper drive motor 29 stops, and the rotation of the base paper feed roller 22 stops. In this state, the plate cylinder 21 clamps the leading end of the base paper 28 to the clamp portion 26 and rotates in the direction of the arrow. At this time, the stationary base paper ejection roller 23 applies tension to the base paper using a built-in one-way clutch and rotates loosely in the base paper transport direction, so that the slack base paper 28 is given appropriate tension. Meanwhile, it is smoothly pulled out from the base paper discharge roller 23 and wound around the plate cylinder 21.
When the base paper feed roller 22 is disposed so as to feed the base paper 28 diagonally downward, it is easy to create downward slack.

る。(Effects) According to the present invention, there is a plate cylinder that rotates after clamping the leading edge of the base paper to wrap the base paper around its circumferential surface, a base paper feed roller that sends out the base paper that has been made in the plate making section, and a base paper feed roller that sends out the base paper that has been made in the plate making section. a base paper discharge roller having a one-way clutch for discharging the base paper, a detection means for detecting that the leading edge of the base paper has reached a clamp position of the stopped plate cylinder, a means for driving the base paper feed roller and the base paper discharge roller, and the base paper means for stopping the driving of the ejecting roller; stopping the driving of the ejecting roller in response to the output of the detecting means; and continuing driving the base paper feed roller for a predetermined period of time, thereby creating a space between the base paper ejection roller and the base paper feed roller. The method is simple because it has a control means for forming slack in the base paper, rotating the plate cylinder after the predetermined time has elapsed, and winding up the slack base paper by rotating the base paper ejection roller having the one-way clutch in a slack manner. This structure makes it possible to securely wrap the base paper around the printing cylinder while giving appropriate tension to the base paper, making the entire device compact and inexpensive to manufacture.
