RU2393305C1 - Method for manufacturing cloth of stretch ceiling with ornament - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: cloth is made of at least two sections joined to each other and made of polyvinyl chloride film. Edges of adjacent sections are matched to each other, folding them with their face side inside, and are joined along edge by a welding seam. Sections joined to each other are made with an ornament. Gasket tape is arranged between sections from polyvinyl chloride film without ornament, with width that is not less than size of joined sections and protruding inside sections. At the moment of welding gasket tape is serially removed stepwise from inner side along welding seam until it is fully removed.

EFFECT: high quality cloth.

Description

The invention relates to the field of construction, in particular to the production of suspended ceilings made from separate sections with a pattern applied to them.

Stretch ceilings are one of the most striking examples of the breakthrough of new technologies in our lives. They are applicable in offices, apartments, pools. Stretch ceilings began to be used as decorative decoration even on yachts, and this is not a complete list of territories conquered by stretch ceilings. Currently, as a material for suspended ceilings, high-quality polyvinyl chloride film (PVC) is widely used, specially formulated for these purposes.

The use of a single web with a pattern made in any way does not create any problems in the manufacture of suspended ceilings.

However, it often becomes necessary to use a canvas with a pattern consisting of several sections interconnected. And here already there are problems associated with its manufacture.

Closest to the claimed invention is a method of manufacturing a stretch ceiling fabric selected by the applicant as a prototype, made of at least two sections of PVC polymer film connected in series, the edges of adjacent sections of the fabric are combined with each other and folded with their front side inward, connecting along the edge with a weld (see patent RU No. 2273703 of 08.09.2004).

This method does not provide for the manufacture of a stretch ceiling from individual sections with a pattern applied to them.

The technical task of the proposed solution is to develop a method of manufacturing a stretch ceiling from interconnected sections with a pattern.

The problem is solved in that in the known method of manufacturing a stretch ceiling canvas made of at least two successively interconnected sections of polyvinyl chloride film, the edges of adjacent sections of which are combined with each other, folding them with the front side inward, and connected along the edge welded seam, according to the invention, the interconnected sections of polyvinyl chloride film are made with a pattern, between them place a cushion strip of film without a pattern, the width is not less than the size connected portions and protruding inside the latter, and at the time of welding sequentially in order of the step pad strips are removed from the inner side along the weld to its complete elimination.

Placing a cushion strip of polyvinyl chloride film without a pattern between the front sides of the areas with a pattern provides a high-quality weld. In this case, the size of the strip in width is chosen not less than the size of the connected sections.

Step-by-step sequential removal of the cushion strip at the time of welding until it is completely eliminated ensures a high-quality seam.

As a result of the patent research, no similar technical solutions known from the prior art that are characterized by the claimed combination of features have been identified, which allows us to conclude that the proposed invention meets the patentability conditions of “novelty” and “inventive step”.

The domestic industry has all the means (material, equipment and technology) necessary for the manufacture of stretch fabric according to the proposed method and its wide use in construction.

The essence of the method is as follows.

The stretch ceiling canvas is made of at least two sections of polyvinyl chloride film with a pattern connected in series, the edges of adjacent sections of the fabric are combined with each other, folding them with the front side inward, and a spacer strip of PVC film without pattern is placed between the sections, across the width not less than the size of the connected sections and protruding inward of the latter, and at the time of welding, sequentially remove the cushion strip from the inside along the weld th joint to its complete elimination.

The method is as follows.

A rolled polyvinyl chloride film with a pattern printed on it is unwound and cut to obtain at least two sections of the required size.

Sections of the film are folded with the front side of the pattern inward. The edges of adjacent sections are combined with each other. For ease of maintenance, the free ends of the sections are rolled up.

Between the sections place a cushion strip of polyvinyl chloride film without a pattern; the strip protrudes inside the connected sections. Its width is not less than the size of the connected sections.

The edge of the sections of the film with the cushion strip is fixed by the press of a high-frequency welding machine to the table. As a welding machine, any high frequency machine known in the art can be used.

When lowering the electrode, the HF current is supplied and the strips are welded. If the length of the sections of the strips is greater than the size of the electrode of the machine, then at the place of welding, the welded strips are pulled in a stepwise order.

As welding is done, the cushion strip is successively manually removed sequentially from the inside until it is completely removed from the seam.

Thus, the invention allows to make a high-quality image of a stretch ceiling canvas with a pattern of individual sections.

Using a canvas consisting of several sections allows you to reduce the cost of the finished product, as well as diversify the range of products through the use of compositions with a pattern. It should be noted that when using such a fabric, the strength of the stretch ceiling is not inferior, and sometimes even exceeds the strength of the whole ceiling.
