Description

[Detailed description of the invention]

[0001]

The present invention relates to an insulating tape, a shielding tape, a semiconductive tape, a convergence tape, a waterproof tape, an adhesive tape and the like which are continuously wound or attached to a power / communication cable or an electric device. The present invention relates to a long-sized wound object such as a tape.

[0002]

2. Description of the Related Art In general, tapes 1 such as an insulating tape, a shielding tape, a semiconductive tape, a convergence tape, a waterproof tape, an adhesive tape and the like which are continuously wound or affixed to a power / communication cable or an electric device are generally used. For example, a 1000 mm wide wide roll is cut into a specified width by a cutting machine such as a slitter and wound around a cylindrical core 2 having the same width as the cut width, and a record disc-shaped roll as shown in the perspective view of FIG. Used in

[0003] When the length of the tapes of these record-shaped rolls is increased, the outer diameter of the roll becomes very large.

However, a taping machine which winds or attaches these record disc-shaped tapes to an electric power / communication cable or an electric device has a limited space for attaching the record disc-shaped roll, and therefore has a limited space. Limit outer diameter.

[0005] These record-shaped rolls are attached to a feeder of a taping machine in several turns. First, the first turn is wound around a tape winding object, and at the end of the winding, the next turn is connected to the next turn. Because it is wound by repeating the intermittent work of winding the next one, when switching tapes, the production speed of the power / communication cable and electrical equipment production line must be reduced each time, and in some cases, it must be stopped. In addition, there has been a great difficulty that the productivity of the production line for power / communication cables and electric devices is significantly reduced.

In order to overcome the limitation of the length of the record-shaped roll by the outer diameter, the tape 1 is placed on the cylindrical core 2 wider than the width of the tape as shown in the perspective view of FIG. There has been proposed a traverse-shaped scroll wound while repeatedly traversing from right to left and from right to left.

[0007] The traverse-shaped scroll has a tape length considerably longer than that of a record disc-shaped scroll, and the productivity of a power / communication cable or electric device manufacturing line is considerably improved. Because the tapes are suddenly turned in opposite directions at both ends of the core, the tapes are wrinkled at both ends of the core, and there is a space between the tapes, so that the volume of the scroll is fully utilized. There was a drawback that not.

[0008]

SUMMARY OF THE INVENTION The object of the present invention is to change the winding method of a roll of tape so that it is not necessary to replace or connect the roll during use, and to use a power / communication cable or an electric device. It is an object of the present invention to provide a long-winding object of a very long length, which is capable of significantly improving the productivity of the manufacturing equipment, making full use of the winding volume, and having no wrinkles in the tape.

[0009]

According to the present invention, a continuous long tape having a width of X (mm) has a width of about NX (mm) [where N is an integer]. On the cylindrical core, first, the terminal is fixed to the left end X ₁ (or right end X _n ) position and wound Y times, and X _{2 to} X _n-1 (or X _{n-1 to} X ₂ ) Are sequentially traversed within one turn and wound around Y times, and are traversed within one turn on the right end X _n (or left end X ₁ ) position and wound 2 Y times, and the right end (or left end is wound). ) To the left end (or
State to the right), further left (or from the right) the right end (or, M stages sequentially repeated Y times winding to left) on the X ₁ to X _n position (where, M is an integer) of stacked Characterized by being continuously wound.

[0010] The cylindrical core used for the long wound object of the present invention can be paper or plastic, but is not limited thereto, and is a cylindrical object having a circular cross section. The shape is such that a circular or square hole is cut out at the center of the cross section. The width of the cylindrical core is width N
(Mm) is determined by the number X of the positions of the core around which the tapes (mm) are wound (in this case, NX), but NX (m
m) may be slightly wider than m).

The tapes that can be used for the long rolled object of the present invention are tapes obtained by cutting a relatively thin, wide-width roll to a specified width in a length direction with a cutting machine such as a slitter. Examples include, but are not limited to, an insulating tape, a shielding tape, a semiconductive tape, a convergence tape, a water blocking tape, an adhesive tape, and the like that are continuously wound or attached to a communication cable or an electric device. If the tapes are too thick, the tapes are likely to wrinkle when wrapped Y times around the cylindrical core and traversed within one round to the right (or left) position. desirable.

The long wound object of the present invention has a width X (m
tapes are in the cylindrical core having a width of about NX (mm) of m), since the stacked each M stage in Y of turns on each position of the X ₁ to X _n, the tape across roll volume Packed, the scroll volume is fully utilized, and the tape is continuously wound.

In the long wound object of the present invention, the number of windings Y wound around each of the positions X _{1 to} X _n on the cylindrical winding core is determined by the thickness, flexibility, elongation, and thickness of the tape itself. The number of windings Y is determined by the wrinkling state at the time of traverse. However, the number of times that wrinkles do not occur during traverse must be selected. Further, the total number of windings MY (outer diameter of the scroll), which is the sum of the number of windings Y and the number of stacks M, is determined based on the space of the taping machine.

The long wound object of the present invention has the same outer diameter as that of a record disc-shaped wound material, and simply increases the width of the cylindrical core by N times, thereby increasing the length of the tapes by N times. Because it is possible, during taping work with a taping machine, there is no need to reduce or stop the line speed of the manufacturing equipment for power and communication cables and electrical equipment during production as in the past,
It significantly improves their productivity.
