12-4) does not come into contact with the web on the suction drum (5).

The second suction hole (5-2) of the winding drum (5) is vacuumed so that even if the web on the unwinding roll (8) side becomes loose, the tensile strength of the winding web (4b) is maintained. There is.

In this state, the tape feeder 04 is run from the origin (a) to the origin (b) shown in FIG. 10, and is memorized by the attached photoelectric switch (12-18).

Next, raise the suction drum (5) until the web (A line, that is, the web contacts the bottom surface of the suction box (6). Of course, for overwork, the chain wheel (5-28 ) is considered to have a safety device using a torque limiter, and in addition to stopping at the web line (4b), the interlocking shaft (5-2
It can also be stopped by a signal from the rotary encoder (43 pulses) in the 13DIJ. As shown in the figure, the suction box (6) is vacuumed and the web (4E) is attracted to the motor (5-
13) to run the cutter and cut the web.

Stop paquining the Saxian drum (5), take out the empty spool (7), and load a new roll.

Leave the web end of the new rewind roll (8) hanging slightly longer.

The Sakushi drum (5) is lowered, and after a while it begins to rotate.

Since a vacuum is applied to the first suction chamber (5-1), a vacuum sensor (not shown, but installed in a fixed pipe) is activated at the same time as the suction is heated, and its signal is used to activate the lifting motor (5-1). 30) is stopped, and the Saxian drum (5) is also placed at the R point to stop its descent.

The clockwise rotation of the saccillin drum (5) continues;
When the first suction hole is closed by the front web, the vacuum sensor is activated and its signal causes the motor (5
-13) stops, rotates in the opposite direction, and continues to rise until the sheet cutter (12-4) comes into contact with the web in response to a pulse signal from the rotary encoder (aS) and stops at a position where it can cut appropriately.

In addition, the position where the rotational movement is stopped is also determined by adjusting the thoracic rotation motor (S) so as to secure the relative position shown in Fig.
-19) Set the pulse and stop.

When the above conditions are set, the tape feeder αtIζ, which was stopped at the origin axis), runs to the origin ω, and during this time, the new web (4d) is cut with the sheet cutter (12-4), and the photoelectric switch (12 As described above, the width dimension and cross-sectional position are detected by -18), and the computer is instructed to calculate the amount of wrap between the old and new webs, as well as the travel distance.

This will be explained using an example shown in FIG.

C is the center line of the tape cutter (11-4), B is the distance from the origin to C, D is the distance from the origin (1) to the origin (2), Xi, Yl, Zl are the old positions, X2゜Y
2. Z2. is the positional relationship of the new web, and M is the amount of overlap between the new and old webs, that is, the length that the adhesive tape (llb) actually runs and adheres.

As mentioned above, the tape feeder ano, which was at the origin I, travels to the origin J and stops. During this time, the cross-sectional positions Q) and (A) are detected by the photoelectric switch (12-8), and the width dimension Y2 of the new web (44) is read.

The old web (4) being wound up on the take-up roll (3)
The width dimension in a) is already stored in the computer by the above-mentioned means, and based on these data, the computer calculates the amount of wrap M and instructs the means by which the tape feeder 0δ travels and its distance.

The base (11m) is as shown in the figure (feed roller (12m)
-16) and (12-17) and sent together with the double-sided adhesive tape (6). Adhesive tape (llb)
It is assumed that the tip of is always at the origin I. Since the air cylinder (12-9) of the tape feeder DJ is operating, the guide roller (12-6) on the right side of the tape feeder (field) presses and holds the base (11a), and the guide roller (12-6) on the left side presses and holds the base (11a). 6) is a double-sided adhesive tape (provided) is held under pressure. In this state, tape feeder 0

In this state, the feed roller (12-15) is rolled to the position of the old web (brown, already cut end face (1)). At this time, the base (lh) is lifted up by the right guide roller (12-6). As shown in FIG.
) is glued to the new web (4d).

At the same time, the sheet cutter (12-4) disposed along the rolling roller (12) cuts the tip of the new web (12-4) along the edge of the adhesive tape (llb).

Since the adhesive tape (llb) has already been cut at the part w1 (1), the compaction roller (12-5) is stopped at position (1) and raised by the air cylinder (12-9). Then, the double-sided adhesive tape (4) is also lifted up and separated from the already bonded tape (Ilb).

A new web with only the difference E between Xl and X2 shown in Figure 10 (4
Although the portion d) is not cut by the sheet cutter (12-4), it will be substantially cut if the value of E is minimized. Alternatively, if the sheet cutter (12-4) is not disc-shaped and is fixed to the main body of the tape feeder 0 so that it does not rotate, and the blade at the lower end is formed long into a knife-shape along the adhesive tape, a new The web (4) is completely cut from beginning to end.

These controls are attached to the tape feeder (2),
The entire process can be carried out by the detection of the traveling photoelectric switch (12-18) and the arithmetic processing by a computer that combines the signal and the pulse of the rotary encoder (12-19).

At this position, the air cylinder (12-9) of the tape feeder (2) is released, and the tape feeder (2) moves up the bracket (12-7) and waits. Base (lla) (yo holder (12)
-10). The tip of the new web (4co) was cut by the sheet cutter (12-9) and was absorbed into the first 3-hole (5-1), but it is released and falls downward.

The Saxian drum (5) stops turning its chest approximately 45 degrees.

The drum lift motor (5-30) causes the saccharging drum (5) to raise the web (brown line, i.e., the line formed by the old web), and the adhesive tape joins the new and old webs by its contact pressure.

The drum (5) is lowered to the web (4b) line, and rotated approximately 60 degrees #1 so that the center of the compaction roller matches the joining point.
Further, the drum (5) rises to the web (browning in).

The rolling pressure roller (5-11) is pressurized by the spring (5-9) and rolls on the joint portion of the web to strengthen the adhesive force.

The rewind box (6) adsorbs the spliced web, but there is a separate case to take up the slack of the web on the unwinding side.
It is slowly moved by a geared motor (not shown), but is stopped before the web breaks due to a signal from a vacuum sensor (not shown).

With the above steps, the joining of the old and new webs is completed, and the machine starts the winding operation again.

This invention is not limited to the embodiments described above, and other embodiments may be implemented within the scope of the invention as set forth in the claims.
