Method of winding and packaging wide wallpaper

Abstract

The invention relates to a method of winding and packaging wide wallpaper, which is wound around a roll on a winding and rotary device, followed by packaging wallpaper in containers for transportation or storage. In the first embodiment of the invention, in the presented process, winding of the wallpaper (3) is carried out onto a winding and rotation mechanism, made in the form of a finished hollow closed cylindrical tube (1) of flexible material, equipped with a valve (2) for supplying and discharging air from it. At the same time, the valve (2) is fixed on one of the tube bases (4). Along the length of the pumped cylindrical tube (1) is fixed the edge of the wallpaper (3) and wound it on the tube (1) until a roll of the required length is obtained. In the second embodiment of the invention, the tube for wallpaper winding is formed from a part of a whole piece of wallpaper material (6) separated from the edge (7) in the form of a fold along the width of the wallpaper. The selected part of the wallpaper material, corresponding to the diameter of the tube (9) being created, is laid in width in two layers and fastened along the perimeter of the formed sides. The valve (10) is installed on one of the bases of the cylindrical tube (9) formed when air is pumped. The rest of the whole piece of wallpaper is wound on the tube (9) until a roll of the required length is obtained. Further, in both embodiments of the described method, the air is released from the tube through the valve to form a flat rectangular structure in the form of wallpaper layers with a tube placed inside. The resulting structure is laid into several layers for packaging in containers and subsequent storage and transportation. Flexible materials such as paper, vinyl, PVC, polyethylene and others are used as material for the manufacture of the tube.

(14) The methods are implemented as follows.

(15) According to the method of winding and packaging wide wallpaper made of flexible material, in accordance with the first embodiment (FIGS. 1, 2, 3, 4), depending on the parameters of the wallpaper to be packed, a tube 1 made in the form of a cylinder (FIG. 1) is selected, having a length corresponding to the width of the wallpaper. Through valve 2, placed, for example, in one of the bases of the tube, air is pumped into the tube to form a rigid cylindrical shape capable of holding the wallpaper wound on it in a vertical position during the process of hanging it on the walls.

(16) The cylindrical tube is placed on an auxiliary working device, convenient for subsequent actions, and the edge of the wallpaper width is fixed on the tube along its length so that the wallpaper roll is parallel to the tube. Then, carefully turning the tube, the wallpaper web 3 is evenly wound on it (FIG. 2), tracking the achievement of the smooth surface of its winding.

(17) As a result, a fully wound roll of wallpaper is obtained, the width and length of which is determined by the required dimensions, corresponding to the dimensions of the wall surface to be papered.

(18) Further, from the tube 1 with a wallpaper roll wound on it through the valve 2, air contained in it is released until a flat rectangular product is obtained (FIG. 3), formed by the wallpaper 3 with a flat tube 1 inside it, represented along the length on both sides by segments of flattened bases 4.

(19) The resulting rectangular product is laid in layers on each other (FIG. 4) and then hermetically packed in a container of suitable size for subsequent transportation or storage. At the same time, the dimensions of the layers, and therefore their number, correlate with the dimensions of the inner volume of the selected container.

(20) According to the method of winding and packaging wide wallpaper made of flexible material, in accordance with the second embodiment (FIG. 5, 6, 7, 8), the structure of the tube for the selected wallpaper to be packaged is formed from the material of the wallpaper, shown in the form of a single roll 5 with a part of the spread out web 6 (FIG. 5). From the part of the spread out web 6, bending it along the width of the wallpaper from the edge 7 towards the roll 5, a segment 8 (FIG. 6) is isolated to form a tube. When forming the tube, the wallpaper material of the segment 8 is laid into 2 layers and the layers are fastened along the perimeter of the sides. As a result, a tube 9 is obtained from the wallpaper material and a valve 10 is installed on one of its short sides (FIG. 7).

(21) Then, as in the first embodiment, air is pumped through the valve 10 inside the tube 9 to form it in a rigid cylindrical shape. Gently turning the tube, the wallpaper web of the roll 5 is evenly wound on it (FIG. 8), monitoring the achievement of a smooth surface of its winding.

(22) As a result, a fully wound roll of wallpaper is obtained, the width and length of which is determined by the required dimensions, corresponding to the dimensions of the wall surface to be papered.

(23) Further, from the tube 9 with a roll of wallpaper wound on it through the valve 10, air contained in it is released until a flat rectangular product is obtained (FIG. 9), formed by the wallpaper roll 5 with a flat tube 9 inside it.

(24) The resulting rectangular product is laid in layers on each other (FIG. 10) and then hermetically packed in a container of suitable size for subsequent transportation or storage. At the same time, the dimensions of the layers, and therefore their number, correlate with the dimensions of the inner volume of the selected container.

(25) It should be noted that in both embodiments of the method, different materials, for example, vinyl, PVC, polyethylene and other flexible materials, can be used for the wallpaper wound around a cylindrical tube. Moreover, paper can also be used as the wallpaper material for the first embodiment of the process.

(26) If desired, a consumer who has bought wide wallpaper can unpack the purchased roll of packed wallpaper and, having carried out all the packing procedures in the reverse order, ultimately get the opportunity to independently carry out the wallpaper hanging procedure.

(27) Example of a Specific Implementation of the Method

(28) When developing the above-described embodiments of the method of winding and packaging wide wallpaper, an experimental test was carried out for the possibility of their implementation.

(29) Embodiment 1. Standard fabric wallpaper with a width of 2.7 m and a length of 5.0 m, wound in the form of a roll was used to conduct the experiment.

(30) To wind such a wallpaper roll on a tube, a sample was purchased in the form of a hollow closed cylindrical product, the length of which was 2.75 m and corresponded to the width of the wallpaper, and its diameter was equal to 0.3 m. Such a tube further in the process of the experiment made it possible to confidently put it vertically with the wallpaper.

(31) Through a Lightblue Spiral valve [4], installed on one of the bases of the cylindrical tube, air was pumped into it using a Intex 68605 pump [5] until a rigid cylindrical shape ensuring a stable vertical position of the pumped tube, was formed.

(32) The pumped tube was placed along its length on an auxiliary device and the edge of the wallpaper was fixed on its cylindrical surface parallel to the axis using double-sided adhesive tape. With the subsequent rotation of the tube parallel to its axis, wallpaper was evenly wrapped around it so that a certain cylindrical structure was formed.

(33) Then, opening the valve, air was released from the tube until a flat structure, consisting of layers of wallpaper and a flat tube placed in its center between the wallpaper, was obtained.

(34) Given its full length, the resulting product was laid in serpentine layers of 0.4 m on each other, so that a compact structure of a 0.3 m high, 0.4 m long and 0.4 m wide was formed. This structure was packed in a cardboard box of 0.5 m0.4 m0.3 m in size for storage.

(35) Thus, this method ensures a convenient solution to the problem of winding and packaging wide wallpaper, which can be effectively used for various economic purposes.

(36) Embodiment 2. In the course of this experiment, standard fabric wallpaper of a width of 2.7 m and a length of 6.0 m, wound in the form of a roll was used, as in the first embodiment. From the edge of the roll, which is in a horizontal position, along its width, a part of the web of a length of 0.95 in was unwound, providing for, when forming a cylinder, the obtaining of a diameter of 0.3 m.

(37) The unwound part of the wallpaper length web was folded across the width and stitched along the edge of the sides, forming a closed rectangular volume. A Lightblue Spiral [4] valve was hermetically sealed in the middle of one of the short sides of the rectangle. Air was pumped into it through the valve using a Intex 68605 pump [5] until a rigid cylindrical tube with a diameter of 0.3 m and a length of 2.7 m was formed.

(38) The pumped tube, together with the rest of the wallpaper roll coupled with it, was placed lengthwise on an auxiliary device. With the subsequent rotation of the tube parallel to its axis, the roll wallpaper was uniformly wound on it so that a certain cylindrical structure was formed.

(39) Then, opening the valve, air was released from the tube to obtain a flat structure consisting of layers of fabric wallpaper and a flat tube of the same material placed in its center between the wallpaper.

(40) As in the first embodiment, the resulting product was laid in serpentine layers 0.4 m in size on each other, so that a compact structure 0.3 m high, 0.4 m long and 0.4 m wide was formed. This structure was packed in a cardboard box of 0.5 m0.4 m0.3 m in size for storage.

(41) Thus, this method ensures a convenient solution to the problem of winding and packaging wide wallpaper, which does not require additional devices and can be effectively used for various economic purposes.
