Definitions
- the present invention relates to a method of making paper lampshades.
- the present invention relates to a method in which the paper from which the lampshades are formed is folded in such a way that it assumes a spatial structure.
- EP 0 144 526 A1 discloses a method for press treatment of fabrics.
- a device with two rotating rollers is used, which rotate in opposite directions at different speeds and are spaced apart from one another.
- the tissue to be treated moves along the two rollers, being guided through a delimiting device which is arranged between the two rollers. Due to the different rotational speeds of the two rollers, the fabric is creased, which leads to a uniform "zigzag" folding of the fabric.
- EP 0 529 766 AI discloses a method for pleating garments.
- the piece of clothing is folded, rolled up, twisted and then clamped in a holding device.
- This holding device is then inserted into a heat treatment device and the garment is simultaneously heat treated and pleated with a saturated current.
- the object of the invention is to fold a paper in such a way that a spatial structure is formed which makes it possible to use the folded paper as a lampshade.
- the present invention provides a method for producing paper lamp shades, which has the following steps: a) wrapping at least part of an outer surface of a cylinder with the paper;
- the method for producing paper lamp screens comprises the following steps:
- FIG. 2 shows a schematic representation of the course of the folding pattern which is achieved by using the method according to the invention.
- FIG. 3 shows a paper lampshade which was produced in accordance with the method according to the invention.
- FIGS. 1 a and 1 b show the first method step in which a paper 100, from which the paper lampshade is produced, is wound around part or all of the outer surface 102 of a cylinder 104. It is obvious that the paper 100 can also be wrapped around the cylinder 102 several times, if this is desired, thereby causing the paper to overlap.
- FIG. 1c is a thread 106 wrapped around the paper 100.
- the wrapping of the paper 100 with the thread 106 can be carried out, for example, by rotating the cylinder 104, as indicated by the arrow in FIG. 1c. This rotation can be done either by an electric motor or by hand.
- the paper 100 wrapped with the thread 106 is pushed together in a direction along the cylinder 104, as is shown by the arrow in FIG. 1d. If desired, the paper 100 can additionally be twisted when pushed together. By pushing the paper together, it is folded so that it assumes a spatial structure.
- the third process step is repeated one or more times.
- the collapsed paper 100 is removed from the cylinder 104.
- a further method step is added (not shown) in which the collapsed, folded paper is pulled apart after removal from the cylinder 104 or is smoothed so that the desired paper lamp shade is created.
- the method according to the invention can comprise further steps according to a further exemplary embodiment.
- the paper 100 is rolled. Depending on the desired shape of the lampshade to be produced, the paper can also be folded after the flexing.
- the folded paper 100 is dried on the cylinder 104. This can be done by adding heat depending on the desired stiffness of the resulting lampshade.
- the paper can be washed and treated with fixatives before it dries.
- fixatives include e.g. Steam or water glass.
- the thread 106 is removed so that the folded paper 100 can be removed from the cylinder 104.
- the papers used can be pretreated before the lampshade is manufactured.
- This pretreatment includes, for example, the gluing of several sheets of paper, the gluing of paper bags and the cutting and / or punching of the papers.
- a treatment can also take place during the manufacture of the lampshade, during which the lampshade is colored or gold-plated, for example.
- the fold pattern produced by the method according to the invention has different sections.
- the method according to the invention produces a folding pattern in which a pointed section 200 and an arcuate section 202 are lined up alternately. These sections 200 and 202 can have different heights and radii.
- the pointed sections 200 arise when they are pushed together on the side of the paper facing the lateral surface 102 at the sections of the paper where the latter is in contact with the thread 106.
- the arcuate sections 202 arise when the paper 100 is pushed together on the side of the paper facing away from the lateral surface 102 when the paper 100 is pushed together.
- the respective course of the folding pattern more precisely the distances of the tip sections 200 from one another, depends on the winding density of the thread 106. This winding density is variable, so that different distances between the tip portions 202 of the folded pattern can arise on a single paper.
- the cylinders 104 used are made of plastic or metal, for example.
- the paper 100 it is not necessary for the paper 100 to be in a specific shape or thickness.
- the paper 100 used can be cut to a predetermined shape and / or folded in a predetermined shape before being applied to the cylinder 104.
- the shape of the cut and / or the folding depends on the desired shape of the lampshade. It is obvious that these measures enable the production of paper lampshades with more complex shapes.
- FIG. 3 shows a lighting fixture 300 with a lampshade 310 produced by the manufacturing method according to the invention.
- the lighting fixture 300 comprises a lampshade 310 and a support frame 320, which comprises two essentially V-support arms 321, 322 which, starting from a foot part 325, extend upwards at an acute angle. Near their free ends, the two support arms 321, 322 have holding elements 323, 324, which grip corner areas of the paper lampshade 310 in order to open it.
- the spherical shape of the paper lampshade 310 due to the manufacturing method according to the invention is brought about by folding the paper along two opposing outer edges of the later screen.
