[Industrial application fields]
The present invention relates to a finishing method for finishing a beautiful corrugated sheet with a large number of pleats in the length direction in a state in which a sewn curtain is suspended, and a finishing apparatus for use in the finishing.
[0002]
[Prior art]
As a curtain, a corrugated curtain with folds and folds, which are formed by alternately forming ridges and valleys with arc-shaped cross sections and lengthening in the length direction and fixed by heat treatment, is known. An example of the method to do is described in Japanese Patent Publication No. 4-23025. According to this method, the first pattern paper and the second pattern paper matching the size of the curtain fabric are overlapped, and a plurality of cylindrical bodies are alternately pressed on both sides to form a corrugated cross-sectional corrugation. Is fixed by steaming, the obtained corrugated paper pattern is stretched, a curtain cloth is sandwiched between the two paper patterns, and the corrugated paper pattern is made into a corrugated form by the elasticity of the paper pattern together with the curtain cloth. After that, put it in the treatment kettle and deaerate it to remove air, then supply steam, cool the inside of the treatment kettle under reduced pressure, and then repeat the steaming and vacuum cooling to pleat the curtain fabric. do.
[0003]
In addition, as disclosed in Japanese Patent No. 2860763, the present applicant can form a corrugated pleat in a lower part other than the top part with the sewed curtain suspended, and does not require a conventional high-pressure treatment pot and vacuum pump. There is provided a curtain finishing method and apparatus suitable for implementation in the final finishing step of curtain manufacture, which saves installation space by miniaturizing the apparatus.
[0004]
[Problems to be solved by the invention]
However, the method of the above Japanese Patent Publication No. 4-23025 requires a high-pressure treatment kettle and a vacuum pump for treating curtain fabric sandwiched between patterns by high-pressure steaming, and is used for molding two patterns. Space, a large space that allows the pattern to be stretched when the curtain is sandwiched between the two sheets, a space for installing the high-pressure treatment kettle and the vacuum pump, and the entire apparatus becomes large. The curtain fabric is sandwiched between the pattern papers, and this is transported to a high-pressure treatment kettle and treated with steam heat.When treated with steam heat, the steam is supplied after degassing the treat kettle, and then cooled under reduced pressure. Further, steaming and cooling under reduced pressure are repeated, so the productivity is low and it is not suitable for mass production.
[0005]
On the other hand, it is known that one or more stitches are formed on the top of the curtain by sewing at regular intervals, and a hook for hanging the curtain is attached to the rear side of the stitch fold forming portion. It is difficult to carry out steam treatment by sandwiching only the part below the top of the curtain with the above-mentioned pattern paper, and also treat the curtain place before sewing with the above-mentioned pattern paper and treating it with steam. If the sewing pleats are formed at regular intervals by sewing, the corrugated folds formed by the pattern may disappear.
[0006]
As a patent No. 2860763, we have also developed a device that can form corrugated pleats in the lower part other than the top part with the sewn curtain suspended, but it takes time to finish the curtain and makes a lot of curtains. Since a sewing company that manufactures it is necessary to install a plurality of devices, it is required to provide a finishing method for finishing the curtain more efficiently.
[0007]
The present invention provides a curtain finishing method and apparatus suitable for carrying out in the final finishing process of curtain production, which can further improve curtain productivity.
[0008]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a means for suspending a curtain having one or more stitches on the top at predetermined intervals, and a portion below the stitches of the curtain is bent in a zigzag cross section. And zigzag vertical pleats formed by the vertical pleat forming means, and a steam injection nozzle for injecting superheated steam onto the curtain on at least one of the front side and the back side of the curtain. The above-mentioned steam injection nozzle for injecting superheated steam is arranged at the position that becomes the bottom of the part, injecting superheated steam into the bottom of the curtain, sandwiching the curtain fabric facing the steam injection nozzle, and The curtain finishing apparatus is characterized in that the curtain is finished in a corrugated shape by having a pleat fixing portion for suction. The curtain is finished by injecting superheated steam, but this part is used as the bottom of the curtain to improve the productivity of the curtain. This device can further improve curtain productivity.
[0012]
Further, the steam injection nozzle because it is disposed in the skirt portion position when the curtain is suspended, it is not necessary to take the configuration of a device for moving, can be the moving parts of the apparatus compact. When finishing the skirt and its vicinity, move the means that suspends the curtain, or make sure that the steam injection nozzle can move only a small range while it is placed near the skirt. Can finish the curtain. As for the arrangement in the vicinity of the skirt, it can be arranged on a beam member installed on a column or the like for hanging the curtain, or it can be configured as a device placed on the floor as a separate body.
[0013]
In addition, by performing steaming heat treatment by sandwiching the curtain between the steam spray nozzle and the pleat fixing portion, the curtain can be more reliably finished even with curtain fabric that is difficult to steam.
