The toilet paper roll 13 does not have a perfect polar pore 12 formed at its center because it is shaped so as to naturally close the central polar pore 12 that is a space by the paper towel 11 '. Insert a dedicated thin core rod (diameter about 1 cm) whose end is elastic by a spring etc. into the incomplete pole hole 12 from the pointed one end side and use this core rod in the toilet paper holder Since it is necessary to do, the thick mounting support rod (diameter about 2.5 cm) of the ordinary holder installed in general households etc. can not be used and a special shaped core rod is required, and a special shaped core rod etc. is required High cost due to There is a problem that becomes
After using the toilet paper 11, a core rod with a special shape remains, and one core rod is put in each bag containing several rolls, so the core rod is discarded every time several rolls are used. There was a problem that it had to be.

好ましい。Means for Solving the Problems In the apparatus for manufacturing a coreless toilet paper roll according to the present invention, a rigid winding shaft having an expandable outer diameter is provided on the central upper surfaces of two drums arranged in parallel, and a riding roll is provided on the upper surface of the winding shaft. It is an apparatus for producing a coreless toilet paper roll having a feature of being provided with. Then, a spray nozzle is provided toward the stretchable hard winding shaft, and when the toilet paper is started to be wound around this winding shaft, it is wound while spraying the adhesive solution from the spray nozzle to the toilet paper. It is preferable to form the tubular portion of the toilet paper in which the toilet paper members are temporarily attached at the center of the paper roll.

ツトペーパーロールが造れる。Effect The coreless toilet paper roll manufacturing apparatus of the present invention is a coreless toilet in which a rigid winding shaft having an outer diameter that can be expanded and contracted is provided on the central upper surface of two drums arranged in parallel, and a riding roll is provided on the upper surface of the winding shaft. Since it is a device that manufactures rolls of scroll paper, toilet toilet paper is supplied to a stretchable and rigid winding shaft whose outer diameter is expanded to a large diameter, and two toilet drums are rotated to rotate the toilets around the circumference of the winding shaft. The binding paper is tightly wound around the winding shaft while being pressed by the riding roll. An uncore toilet toilet having a relatively large hole at the center thereof, which is approximately the same as the outer diameter of the winding shaft, by reducing the outer diameter of the winding shaft from the roll-shaped toilet paper tightly wound around the winding shaft to remove the winding shaft. Can make paper rolls. In addition, since the paper cylinder core is not used at the time of production and it can be attached to a normal holder at the time of use, the cost can be made low by not using the specially shaped core rod, and the length of the tightly wound portion is the same volume (bulk) and a long toilet tray. You can make coreless toilet paper rolls wrapped with paper.

つことができる。In the manufacturing apparatus of this embodiment, a thin aqueous solution (adhesive solution) having a polyvinyl alcohol (PVA) concentration of about 0.5% is applied to the toilet paper 4 from the spring nozzle 6 at the beginning of winding the toilet paper 4 on the winding shaft 1. The toilet paper 4 is temporarily sprayed by the PVA aqueous solution sprayed over a length of about 50 cm, and the toilet paper cylinder 7 is formed by temporarily attaching the toilet paper to each other. The shape retention of the peripheral portion of the large hole 9 of 8 is further improved. Further, if a heater is provided inside the winding shaft 1 or a heater is provided outside the winding shaft 1 to heat the winding shaft 1, the sprayed adhesive liquid will be dried a little quickly, and the toilet paper Since it is weakly temporarily attached, when the winding shaft 1 is drawn out from the toilet paper roll 8 by reducing the diameter, the toilet paper tubular portion 7 formed at the beginning of winding of the toilet paper roll 8 creates a coreless toilet. The shape of the paper roll can be kept better.

ペーパーロールの形状を更に良く保つことができる。EFFECT OF THE INVENTION In the apparatus for manufacturing a coreless toilet paper roll of the present invention, a rigid winding shaft having an expandable and contractable outer diameter is provided on the central upper surface of two drums arranged in parallel, and a riding roll is provided on the upper surface of the winding shaft. Since it is a manufacturing device for coreless toilet paper rolls, the toilet paper is wound tightly into a roll shape while pressing it with a riding roll on a hard winding shaft with an expanded outer diameter, and the outer diameter is reduced to pull out the winding shaft. Allows you to easily make a coreless toilet paper roll with a large hole in the center, and uses a specially shaped core rod because it does not use a paper tube core during production and it can be attached to a normal holder as it is when used. You can make the cost cheaper because you don't. The effect of being able to make a toilet paper roll wound with a long toilet tape in the same volume (bulk) as it is tightly wound and not to deform the coreless toilet paper roll in the form of a roll having large holes There is. Furthermore, since it has no core, there is an effect that nothing remains after use. Further, in a manufacturing apparatus in which a spray nozzle is provided toward the winding shaft, an adhesive liquid is sprayed from the spray nozzle at the beginning of the winding to form a cylindrical toilet paper roll at the beginning of the winding. The shape of can be better maintained.
