Description

FIELD OF THE INVENTION

The invention relates to the pulp and paper industry and, in particular, to the field of production of hygienic paper products, namely toilet paper.

State of the art

Known toilet sanitary paper made in the form of a roll (Abstract of utility model No. 29224, published 2003.05.10).

The set of signs "toilet ... paper" analogue coincides with part of the signs of the claimed invention. The paper does not have a variable transverse size in length.

The prototype of the invention is toilet paper, which is made in the form of a paper web rolled up with a variable transverse size along the length, and the transverse size along the length of the canvas changes periodically. Separate sections of the web are oval and the web is perforated in narrow places (German Patent DE 4004075, 08/14/1991).

The set of signs “toilet paper is made in the form of a paper sheet, rolled up into a roll, with a variable transverse dimension in length, and the transverse dimension along the length of the canvas changes periodically” prototype coincides with part of the features of the claimed invention.

The disadvantage of the prototype is the complexity of manufacturing a roll with separate sections in the form of ovals.

Disclosure of invention

The objective of the invention is to reduce the cost of toilet paper. The technical results shown in the manufacture of toilet paper are as follows:

- simplification of the manufacturing process of toilet paper having a variable transverse dimension in length;

- reduction of paper losses when cutting toilet rolls having a variable transverse dimension in length from a wide roll of paper.

The technical result manifested by the use of toilet paper is as follows:

- reducing the effort to break the fabric without the use of perforation and at the same time increasing the hygiene safety of the fabric.

Toilet paper is designed to provide practical measures to preserve human health, in particular for hygienic cleaning of the excretion products of the human body.

Technical results are achieved in that the toilet paper is made in the form of a rolled paper roll with a variable transverse dimension in length, the transverse dimension along the length of the web being changed periodically, and the toilet paper is made when cutting the paper roll into smaller toilet paper rolls, and the lateral edges of the toilet paper roll are angled to each other, and the toilet paper is made without perforation of the paper web, and the toilet paper web is made with a maximum transverse dimension measuring from 0.05 to 0.2 m and with the ratio of the minimum transverse dimension to the maximum transverse dimension from the range of values from 0.1 to 0.9999.

The set of characteristics “toilet paper is made when cutting a roll of paper into smaller rolls of toilet paper, and the lateral edges of the roll of toilet paper are angled to each other, and the toilet paper is made without perforation of the paper web, and the toilet paper web is made with a maximum transverse dimension of 0.05 to 0.2 m and with the ratio of the minimum transverse dimension to the maximum transverse dimension from a range of values from 0.1 to 0.9999. ”Distinguishes the invention from the prototype.

A simplification of the manufacturing process of toilet paper having a variable transverse dimension in length is that toilet paper rolls are cut from a large wide roll of paper by cutting the roll with mechanical scissors. Each subsequent cut is carried out at an angle to the previous cut. The lateral edges of the cut toilet rolls are flat. Edges (planes) are located at an angle to each other. When the roll of paper is deployed after cutting, a web with a variable transverse dimension in length is obtained, the transverse dimension changing periodically. The edges of the resulting toilet paper are made in the form of straight lines located at an angle to each other.

For comparison: in the prototype, the oval cut of the web is carried out by curly cutting of the fully unfolded web, after which the web is rolled up and as a result, toilet paper is produced in a roll. In the manufacture of the prototype there are large losses of paper (up to 15%), which increases the cost of the final product.

Simplification of production is also achieved by rational selection of the geometric parameters of the canvas, namely the establishment of the ranges: the ratio of the minimum transverse size to the maximum transverse size (from 0.1 to 0.9999); maximum transverse canvas size (from 0.05 to 0.2 m). Going beyond these ranges (as production practice shows), in the manufacture of toilet paper, can lead to a significant increase in the cost of equipment for the manufacture of toilet paper.

The reduction of paper losses when cutting toilet rolls from a wide roll of paper is achieved by the fact that toilet rolls are cut from a large wide roll of paper by cutting the roll with plane shears. This ensures the non-waste production of toilet paper with a variable transverse size along the length of the canvas and the cost of the final product.

Reducing the effort to break the fabric without the use of perforation and at the same time increasing the hygienic safety of the fabric is achieved by rational selection of the geometric parameters of the toilet paper roll and canvas and performing it without perforation.

The toilet paper web is made with a periodically varying transverse dimension with a ratio of the minimum transverse dimension to the maximum transverse dimension from a range of values from 0.1 to 0.9999. This will allow in a wide range to control the force of separation of the web section from the roll. And besides, it will make paper for people of different ages (children, adults).

The toilet paper canvas is made with a maximum transverse size from 0.05 to 0.2 m. This will make it possible to produce paper for people of different ages (children, adults).

Brief Description of the Drawings

Figure 1 shows toilet paper in a roll.

Figure 2 shows the toilet paper sheet in expanded form. The toilet tissue paper web is made in length with a variable transverse size. Two side edges of the canvas are made in the form of curved lines.

The implementation of the invention

Toilet paper can be made in length with a variable transverse size in the following ways:

a) manually using scissors;

b) at a paper mill when cutting a roll with mechanical scissors into smaller rolls of toilet paper.

Figure 1 shows a roll of toilet paper, in which the side edges 1 and 2 are located at an angle 3 to each other. Corner 3 is formed when cutting a roll into smaller rolls of toilet paper. When deploying paper from such a roll, the length of the web will be with a variable transverse size (see figure 2). Moreover, the size will change periodically. Cross sections of the web between points 4 and 5, as well as between points 6 and 7, have the smallest tensile strength. It is along these sections that the separation of the necessary piece of toilet paper will be carried out.

It is advisable to carry out a universal toilet paper sheet for a wide range of consumers with a length of 60 m, as well as with a maximum transverse size of 0.12 m.

To ensure ease of tearing, it is advisable to perform a universal web with a ratio of the minimum transverse dimension to the maximum transverse dimension of 0.2 (this is from the range of values from 0.1 to 0.9999).

The implementation of toilet paper according to the claimed invention is much simpler than the manufacture of the prototype, and will allow you to create a cross-section along the length of the canvas with reduced tensile forces (weakened cross-sections) compared to other cross sections of the canvas without using perforation of the canvas. It is along these sections that the separation of the required quantities of pieces of toilet paper will take place.

In the prototype, two surfaces (for example, the front and the back) of toilet tissue were connected through the holes. It was through these openings that contamination (for example, microbes) could penetrate from one side of the canvas to the other.

The claimed invention achieves a reduction in the effort of breaking the web without the use of perforation, which provides a simultaneous increase in the hygienic safety of the web.

Thus, the claimed technical results are achieved.
