19 to 22 are schematic block diagrams for explaining the operation of such a conventional sheet material feeding device,
23 to 27 are views for explaining the problems of this conventional device.

As shown in FIG. 19, the conventional sheet material feeding device has a sheet material feeding portion 110 for feeding the sheet material through a guide roller 141 and a switching mechanism 120 for switching the original material. There is. Sheet material supply unit 1
10 is provided with a turret 111 capable of turning around a fulcrum 112. At both ends of the turret 111, a support shaft 113a that supports the original fabric 114a and a support shaft 113b that supports the original fabric 114b are provided. Here, the original fabric 114b is a new original fabric, and an adhesive tape 118 is provided at the tip thereof. Further, the turret 111 has rollers 115a for guiding the sheet material,

41, the switching mechanism 120
Is at a position that does not hinder the turning of the turret 111 (outside the area A indicated by the broken line). When the remaining amount of the original fabric 114a becomes small, a new original fabric 114b starts to rotate and the sheet material 11
The traveling speed of 7a and the peripheral speed of the original fabric 114b are matched. Next, as shown in FIG. 20, the switching mechanism 120
The arm 121 of is brought close to the sheet material 117a. next,
As shown in FIG. 21, the press roller arm 124
2 is moved closer to the sheet material 117a and the sheet material 117a is pressed against the original fabric 114b by the press roller 125.
As shown in FIG. 2, the adhesive tape 118 of the new original fabric 114b and the sheet material 117a are bonded together, and then the sheet material 117a is cut by the cutter 127.

[0006]

However, when the original fabric is switched in the above-mentioned conventional apparatus, as shown in FIG. 23, the sheet material 117 from the new original fabric 114b is obtained.
A double portion 119 that overlaps with the rear end of the sheet material 117a of the original fabric 114a was always formed at the front end portion of b. this is,
Since the cut end of the sheet material 117a cut by the sawtooth cutter 127 as shown in FIG. 24 has a sawtooth shape as shown in the plan view of FIG. 25, the adhesive tape 118 is provided at the rear end of the sheet material 117a. Because it cannot be attached. Further, the cutting position by the cutter 127 needs to be separated from the press roller 125 in order not to damage the new original fabric 114b.
When the sheet material is cut at a position away from 25, since the rear end portion of the sheet material 117a located on the downstream side of the press roller 125 is long, a large sway occurs at the rear end portion of the sheet material 117a. This is because it becomes difficult to place the rear end of the 117a at a predetermined position on the adhesive tape 118.

When such a double portion 119 is formed, the double portion 1 is formed when the sheet material passes between the nip rollers 130 and 131 in the subsequent step, as shown in FIG.
There is a problem that slippage occurs between 19 and the new sheet material 117b, the driving force of the rollers escapes, and the conveyance of the sheet material is disturbed. Also, in the air floating dryer 132 as shown in FIG.
9 disturbs the flow of the air 133 to cause irregular shaking of the sheet material. Further, when the sheet material is paper of a printing machine, there is a problem that the tension of the sheet material is disturbed and the print quality is deteriorated.

Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to continuously supply the sheet material from the original fabric without stopping even when switching the original fabric. It is an object of the present invention to provide a sheet material supply device that can be performed by using a sheet material and that does not have a portion where sheet materials overlap each other at a connection point.

Next, as shown in FIG. 8, the cylinder 2
6, the perforation cutter 27 is brought into contact with the old sheet material 17a running on the roller 15a, and the perforation is made on the old sheet material 17a. Here, the initial position of the teeth before the perforated cutter 27 is brought into contact with the old sheet material 17a is a predetermined fixed position. Further, when the perforated cutter 27 is brought into contact with the old sheet material 17a for a certain period of time or more, perforations are formed at a plurality of locations, so the perforated cutter 27 contacts the sheet material 17a for a moment and then immediately releases it. Further, the timing of perforating the old sheet material 17a by the perforation cutter 27 is the position (or angle) α where the adhesive tape 18 is provided on the new original fabric 14b and the new original fabric 1
It is controlled by a control unit (not shown) based on the peripheral speed of 4b. That is, the time when the perforation position of the old sheet material 17a reaches the press roller 25, and the central position of the adhesive tape 18 (which is also the tip position of the new sheet material 17b of the new material 14b) are directly under the press roller 25. It is controlled so that the time to arrive at is the same.

Since the adhesive force between and is much stronger, the back surface of the adhesive tape 18 is separated from the new original fabric 17b as shown in FIG.

Also, at this time, the pressing portion 29 causes the pedestal 16
The timing at which the sheet material 17a is pressed against a is determined by the distance from the perforation cutter 27 to the press roller 25 (at this distance, the initial position of the teeth of the perforation cutter 27 (position γ in FIG. 8) comes into contact with the press roller 25). Position (including the length of the circumference up to position δ in FIG. 8) and the first sheet material 1
7a and the traveling speed of 7a. That is, the position of the perforations is immediately before contact with the adhesive tape 18,
The pressing portion 29 operates at the moment when it comes to a position as close as possible to the press roller 25. This is to minimize the swaying of the rear end of the sheet material that occurs after the sheet material is cut and to accurately place the rear end of the old sheet material 17a on the adhesive tape 18.
