Abstract

PURPOSE:To prevent adhesion faces from becoming protuberant even when slippage occurs when reinforcing members are put together for adhesion by a method wherein nonadhesion faces are formed on both sides in the breadthwise direction on the opposite faces of two tape-like reinforcing members for bonding the front end of running paper and a traction member together, and the adhesion faces are formed to parts at the center, excluding the nonadhesion faces. CONSTITUTION:Two tape-like reinforcing members 100 are for bonding the front end of running paper and a traction member together, and nonadhesion faces 112 are formed on both sides in the breadthwise direction on the opposite faces of the tape-like reinforcing members 100. The width (b) of the nonadhesion faces 112 is desirably to be 10-20% of the entire width (a) of the reinforcing member 100. As occasion demands, the nonadhesion faces 112 are formed only to parts where the reinforcing members 100 are to be stuck together. Therefore, the adhesion faces are not protuberant even though relative slippage occurs between the reinforcing members when the reinforcing members are put together for adhesion.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running paper reinforcing member for joining a towing member and a leading end portion of a running paper to reinforce the leading end portion of the running paper when the web is passed through a rotary press.

[0002]

2. Description of the Related Art With the remarkable increase in the number of pages of newspapers in recent years, the number of bends in the movement path of the pulling member for guiding the running paper to convey it to the folding section is increasing, and the distance is also increasing. For this reason, a large tension is applied to a portion of the leading end of the running paper that is joined to the traction member, and the running paper is broken. In particular, for a GS paper pulling member that needs to change the direction of the running paper, the bending of the moving path is complicated, and the running paper is more likely to break. Therefore, even if the number of pages of the newspaper increases, the path for guiding the running paper to the folding part is complicatedly bent, and even if it is long, the tip of the running paper will not break. In order to meet this demand, the applicant of the present invention discloses a new running paper reinforcing method and device in order to meet this demand. Is proposed.

According to the invention of the above-mentioned Japanese Patent Laid-Open No. 4-341456, the tip of the reinforcing tape is attached to both sides of the paper guide which pulls and conveys the running paper, and the rear portion of this tape is most tensioned at the tip of the running paper. It is attached from both sides to the part that is covered by the reinforcement. Therefore, the running paper can be sufficiently reinforced, the towing member is bent in a complicated manner, and the leading end portion of the running paper is not broken even when the running paper travels on a long moving path.

[0004]

In this case, commercially available kraft tape, vinyl tape, nylon tape, paper tape, etc. are used as the reinforcing member for joining the leading end portion of the running paper with the pulling member. . However, all of these tapes have adhesive applied over the entire width of the tape, so in order to prevent the adhesive surface from sticking out when two tapes are stacked and attached. The tape stacks of must be matched exactly.

That is, if the tapes are not superposed as much as possible and the two tapes are misaligned with each other, the adhesive surface will stick out. If the paper is threaded with the adhesive surface protruding, the adhesive adheres to the turn bar and the guide roller, which causes a great resistance when the traveling paper is conveyed, which hinders the smooth conveyance of the traveling paper. However, there is a problem that a paper break occurs at a place where the adhesive is attached. On the other hand, to overlap the two tapes so that the adhesive surfaces do not shift,
Since the precision of the reinforcing device must be increased, the cost of the device becomes very high.

The present invention has been made in order to solve the above-mentioned problems, and provides a running paper reinforcing member for preventing the adhesive surface from protruding even if two opposing tapes are misaligned during superposition. For the purpose of provision.

[0007]

In order to achieve the above object, a reinforcing member for a running paper according to the present invention is two tape-like reinforcing members for joining a pulling member and a leading end portion of the running paper. Of the tape-shaped reinforcing member, non-adhesive surfaces are formed on both sides in the width direction of the opposing surfaces, and an adhesive surface is formed in the central strip portion excluding the non-adhesive surface, preferably the non-adhesive surface. Are 10% to 20% of the total width of the reinforcing member. Further, if necessary, the non-adhesive surface is formed only in the portions where the tape-shaped reinforcing members are stuck together.

[0008]

According to the running paper reinforcing member of the present invention, since no adhesive surface is formed on both sides in the width direction of the tape-like reinforcing member, even if the tapes are misaligned and overlapped, the central strip portion is formed. The adhesive surface of does not protrude from the side of the reinforcing member.

The turn bar 9 is fixed at an angle of 45 degrees with respect to the paper flow, and one turn bar 9 is positioned above the other turn bar 10 by the diameter of the bar.

A first guide rail 13 is provided on the side of the drag roller 1 on the side frame H side. The first guide rail 13 reaches the running paper cutting unit 50 through a paper feeding unit and a printing unit (not shown), and is continuously provided from here to the folding unit 60 (see FIG. 3). A second guide rail 14 is installed from the running paper cutting unit 50 to the folding unit 60 so as to correspond to the side of the GS paper 2b closer to the HS paper (see FIG. 3).

These first and second guide rails 13,
As shown in FIG. 4, 14 has a box shape in which openings 13a and 14a are formed in the central longitudinal direction of one side surface. A plurality of rolling members 15 are provided inside the box-shaped guide rails 13 and 14, and the rolling members 15 further include guide rails 1 as shown in FIGS.

The reinforcing device is a tape reel 21 around which the tapes 100, 100, which are the reinforcing members of the present invention, are wound.
21, adhesive rolls 23, 23, and this adhesive roll 2
Cylinders 24, 24 for rocking 3, 23, and tape 1
The cutters 25 and 25 for cutting 00 and 100 and the pressure bonding rolls 26 and 26 are arranged above and below the GS paper 2b with the side passage path near the HS paper 2a in between.

Next, an embodiment of the reinforcing member for running paper according to the present invention will be described. FIG. 6 shows a partial plan view of an embodiment in which the reinforcing member is a long tape. In the tape 100 of this embodiment, the adhesive surface 111 is formed by applying an adhesive or the like to the central band portion of the tape body 110 in the longitudinal direction. Further, both sides of the adhesive surface of the central band portion, that is, both sides in the width direction of the tape body 110 are non-adhesive surfaces 112 to which no adhesive is applied. This non-adhesive surface 11
No. 2 is a case where it is formed without applying an adhesive, a case where an adhesive is applied to the entire surface of the tape and then a thin tape for a mask is attached only on both sides, or an adhesive is applied to the entire surface of the tape. In addition, various forming methods can be adopted, such as attaching a masking tape to the entire surface and then peeling off only the mask portion of the central band portion.

Here, the non-adhesive surface 1 of the tape 100
The width b of 12 is 10% of the width a of the tape body 110.
-20%. This width b is determined by the tape sticking accuracy of the sticking rolls 23, 23 in the above-mentioned reinforcing device. That is, the tape 1 is applied to both sides of the paper guide 18 and the running paper 2 by the application rolls 23.
The width is slightly larger than the maximum value of the relative displacement in the tape width direction between the two tapes that occurs when 00 and 100 are stacked and attached.

Usually, the width b of the non-adhesive surface 112 is 10%.
If it is smaller than 100%, the adhesive surface 111 may stick out to cause the same adverse effect as in the conventional tape. If it is larger than 10%, the width b of the non-adhesive surface 112 becomes unnecessarily large.
The entire tape is too wide.

The relative displacement in the width direction between the two tapes 100, 100 generated by the reinforcing device currently used is 4
mm to 8 mm, while overall tape width is 40 mm
Therefore, the width b of the non-adhesive surface 112 of the tape 100 is 4 mm to 8 mm.

A description will be given of a case where the running paper is reinforced by the above-described reinforcing device using such a running paper reinforcing member, that is, a case where the paper guide 18 and the leading end portion of the running paper 2 are joined. The tape reels 21 and 21 have the above-described tape 10 whose both sides in the width direction are non-adhesive surfaces.
0,100 is wound, and the tip of the roll is an adhesive roll 23,
Has reached 23.

Here, the paper guide 18 is projected from the guide rail 14 and overhangs between the adhesive rolls 23, 23. When the adhesive rolls 23, 23 are closed, two paper guides 18 are provided on both sides of the paper guide 18. The tapes 100, 100 are attached facing each other. Next, the paper guide 18 is returned to the position of the pressure rolls 26, 26 and the tapes 100, 10
0 is crimped. At the same time, the adhesive rolls 23, 23 are opened and the rear parts of the two tapes 100, 100 are opened (state of FIG. 7).

Next, when the running paper 2 advances and its leading end is located between the adhesive rolls 23, 23, the adhesive roll 2
3, 23 are closed, and the two tapes 100, 100 are affixed to both surfaces of the front end portion of the running paper 2 so as to face each other (state indicated by a chain line in FIG. 7). After that, the two tapes 100, 100 are slightly advanced, and then cut by the cutters 25, 25. As a result, the paper guide 18 and the leading end of the running paper 2 are joined together while being reinforced by the two tapes 100, 100.

At this time, it is assumed that a relative displacement occurs between the two tapes 100, 100, and that one side of the side edges of the tapes sticks out at the portions where the tapes are stuck together, as shown in FIG. Also, the protruding portion is the non-adhesive surface 11
Since it is 2, the adhesive will not adhere to the turn bars 9 and 10 even if the paper is threaded in this state.

The tape sticking length of the paper guide 18, the tape sticking length of the running paper 2, and the paper guide 18
If the distance between the running paper 2 and the running paper 2 is clear and the tape sticking control can be performed with high accuracy, the tape 100
It is not necessary to form the non-adhesive surface 112 at the portion where the paper guide 18 and the running paper 2 are attached. That is, as shown in FIG. 9, the paper guide 18 of the tape 100, 100
Non-adhesive surface 112 only when the non-adhesive surface is located between the paper guide 18 and the traveling paper 2 side (for example, the state shown in FIG. 9 is included).
May be formed.

Further, the shape of the reinforcing member can be various shapes such as a sheet shape depending on the reinforcing device or the reinforcing method, and is not limited to the tape shape.

[0027]

As described above, according to the running paper reinforcing member of the present invention, since non-adhesive surfaces are formed on both side edges in the width direction, when the reinforcing members are laminated and attached, the reinforcing member is provided. The adhesive surface does not protrude even if a relative displacement occurs. Therefore, the adhesive is not attached to the turn bar or the like, and the traveling paper can be smoothly conveyed through the paper. Further, since it is not necessary to increase the accuracy of superimposing the reinforcing members in the reinforcing device, the cost of the running paper reinforcing device is not increased.
