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.

1 .- 7 . (canceled) 
     
     
         8 . A method of winding and packaging a sheet of wide wallpaper having at least an edge and a dimension corresponding to the vertical dimension of a wall onto which it is to be affixed, for storage, transportation and use, comprising:
 providing a cylindrically shaped winding core having a longitudinal axis, the winding core comprising an inflated tube of flexible material having a length substantially the same as the vertical dimension of the sheet of wide wallpaper and comprising a first end and a second end, the winding core shaped for rotating the winding core about its longitudinal axis;   providing a first end cap and a second end cap each sealingly connected to one of the first end of the tube and the second end of the tube so as to create an airtight-hollow cylinder with end caps, the airtight-hollow cylinder laying substantially flat when not inflated;   providing at least one valve, extending through at least one of the first end cap and second end cap, into the airtight-hollow cylinder, for the alternative inflation and deflation of the airtight-hollow cylinder;   inflating the airtight-hollow cylinder by inserting gas therein, through the valve;   affixing the edge of the wallpaper to the winding core;   rotating the winding core so that the sheet of wide wallpaper is uniformly wound thereon forming a roll consisting of successive layers of wide wallpaper overlapped one over another, thereon:   deflating the airtight-hollow cylinder by releasing gas through the valve until the airtight-hollow cylinder is flattened, forming a flattened structure in the form of wallpaper layers having a flattened tube inside;   serpentine-folding the resulting flat structure along planes perpendicular to the longitudinal axis to form a compact package and laying, in several layers folds, for packaging in containers for transportation or storage; and   subsequently unfolding the compact package and positioning the unfolded package at a wall and reinflating the flattened structure to again form a winding core in vertical orientation against the wall and unrolling the wallpaper laterally along the wall in one piece for application without an external support.   
     
     
         9 . A method according to  claim 8 , wherein the edge of the wallpaper is fixed along the length of the tube using means to affix, such as double-sided adhesive tape, adhesive, or spaced mechanical fasteners along the length of the tube. 
     
     
         10 . A method according to  claims 8 or 9 , wherein the valve is installed on one of the end caps of the cylindrical tube. 
     
     
         11 . A method according to any one of  claims 8-10 , wherein the material used for the tube manufacture include vinyl, PVC, polyethylene or a laminate thereof and other flexible materials. 
     
     
         12 . A method according to  claim 8 , wherein the compact package has a height not exceeding about 0.30 m and a footprint not exceeding about 0.40 m×0.40 m. 
     
     
         13 . A method according to  claim 8 , wherein the container for shipping is rectangular shipping box. 
     
     
         14 . A method of installing a wide wallpaper sheet, shipped as a serpentine-folded flattened roll around a deflated inflatable tube within a package, comprising.
 (i) placing the package at a wall;   (ii) re-inflating the tube in situ to restore a cylindrical core in a vertical orientation against the wall; and   (iii) unrolling the wallpaper laterally along the wall in one piece for application without an external support frame.
