Technical Area

[0001] The present invention relates to a trousers waistband end folding and sewing machine, which enables the waistband lining and waistband fabric sewn to both sides of the upper part of the trousers to be folded inward and the sewing of the waistband in the automation system.Known State of the Art

[0002] Trousers are defined as a type of lower garment that can be worn below the waist and can be made in different lengths from below the knee to the ankle, which can be worn by men and women. In another definition, trousers are also defined as a garment consisting of two parts extending from the waist to the ankles and wrapping each leg separately. Trousers can be long or short in length, with narrow or loose legs (sailor trousers), or attached to the legs (ski trousers). The trousers can be rolled up or straight. Trousers can have pockets on the front, back or sides. There are different types according to different fabrics and fabrics such as jeans, fabric trousers, linen trousers, velvet trousers. Regardless of the form, trousers, one of the main elements of men's clothing, always consist of the same parts. These are the four major parts that make up the body of the trousers and the secondary parts called the pat part where the waistband, button or zip is sewn.

[0003] In trousers sewing, the waistband section is sewn to the upper part of the trousers. This sewing is done in two ways. In belt sewing, the waistband lining and waistband piece fabric is kept wide and folded in half from the neck and closed to wrap the upper part of the trousers on both sides and sewing is done. When it comes to the zip section on the front of the trousers, the ends are sewn and the end part of the waistband part is also closed. This process can be done with machines and by hand.

[0004] As the second method in trousers waistband sewing; two pieces of waistband lining and waistband piece are sewn on both sides of the trousers upper part. The ends of the waistband lining and waistband piece fabric are folded inwards to form a locked and closed end. These ends are sewn together on the sewing machine. This process can only be done by hand. In this case, there is a loss of time in the production and sewing department. In addition, since the process is done by hand, human error is also quite common.

[0005] As can be understood from the above, it is clearly observed that there is a need for a system that can automate the sewing of two waistband lining and waistband piece fabrics to the upper part of the trousers, after the waistband end is sewn to the upper part of the trousers, the waistband end is folded and placed inside by making an inward lock without cutting, and then sewing.

[0006] Although there are some solutions to manual folding such as JPH06105980A, it discloses a folding ruler system with plates to position and fold the fabric. The present invention has a more complex setup with adjustable beams and eccentric shafts, allowing for precise control over waistband fabric and lining, with customizable folding distances while providing greater flexibility for folding and stitching waistbands.

[0007] The trouser waistband end folding and sewing machine of the invention is defined by claim 1. Preferred embodiments are specified in dependent claims 2 to 4.

[0008] This invention, which is related to the trousers waistband end folding and sewing machine, provides the waistband lining and waistband piece fabric as two pieces on both sides of the upper part of the trousers in the waistband area sewing of the trousers from the clothing products, after the placement and longitudinal sewing of the waistband lining and waistband piece fabric on both sides of the upper part of the trousers, the waistband end is folded inward as a lock and the sewing is done by making a locked fold by making a fold at each stage of the inward folding lamellas in the automation system, and then the waistband end is taken and transported to the sewing machine and sewn, this invention related to the trousers waistband tip folding and sewing machine overcomes the disadvantages described above in its entirety, and its feature is; is an automation system that enables the ends of the waistband lining and waistband piece fabric, which are sewn to the upper part of the trousers, to be folded in a lock manner and then sewn.

[0009] The trousers are placed on the trousers waistband end folding and sewing machine as two pieces of the user's waistband lining and waistband piece fabric on both sides of the upper part of the trousers and sewn from the neck. Waistband ends can be sewn from the right and left sides as the waistband end part is not sewn. For waistband end sewing, placement is made on the right folding section or left folding section. The open ends of the waistband ends placed in the right folding section or left folding section start the folding process.

[0010] In the right folding section or the left folding section, the waistband lining and the waistband piece fabric are placed in two pieces on both sides of the upper part of the trousers and placed on the lower fixing slat and the upper fixing slat sewn from the neck. The lower fixing slat and the upper fixing slat can stand on each other at a distance determined by the user. By determining the distance between the user, the waistband end of trousers made of different thickness fabrics can be sewn. The user can increase the distance in products such as jeans with thick fabric, and decrease the distance in thin fabrics such as linen trousers.

[0011] In the waistband end section placed on the lower fixing slat and the upper fixing slat, the lower fixing slat goes down. In this case, a gap is opened between the lower fixing slat and the upper fixing slat in the range determined by the user. Here, a gap is created between the two waistband fabrics. In the next step, the clamping slat from the top descends downwards. The clamping slat clamps the upper waistband fabric to the upper fixing slat and makes the fabric end ready for the next folding process.

[0012] In the next stage, the bottom folding slat is in operation. The lower waistband end fabric, which is clamped and fixed to the base by the lower fixing slat, is folded inwards and placed inwards. In this case, the lower folding slat folds the lower waistband end fabric inwards between the two waistband fabrics with the forward movement provided by the lower folding eccentric shaft.

[0013] In the next stage, the upper folding slat operates. The upper waistband end fabric, which is fixed by the clamping slat to the upper fixing slat by clamping, is folded inwards and locked folding is provided while it is placed inwards. At the end of the waistband, the lower waistband fabric and the upper waistband fabric are folded locked within each other. In this case, the upper folding slat folds the upper waistband end fabric inwardly between the two waistband fabrics with the downward and forward movement provided by the upper folding eccentric shaft.

[0014] In the right folding section or the left folding section, the width of the lower fixing slat is greater than that of the upper fixing slat. Due to the fabric thickness of the folded fabric during the folding process, the width of the upper fixing slat is kept less in order to ensure fold alignment.

[0015] After the folding is completed, the clamping pin, the lower folding pin and the upper folding pin are pulled into place and the lower fixing pin and the upper fixing pin are brought together to release the folded waistband end. On the folded waistband end, the transport slat comes from the sewing section. When the transport slat arrives, the lower fixing slat and the upper fixing slat are pulled backwards by the piston movement of the trolley on the rail. In this case, the folded waistband end remains on the carriage slat. The carriage carries the folded waistband end to the sewing section.

[0016] In the sewing section, the folded waistband end is sewn with the known method of the technique. After sewing, the user can repeat the process in the right folding section or in the left folding section for sewing the waistband end at the other end of the trousers. In this way, the process of folding and sewing the trousers waistband end can be provided by an automation process. Automation increases the production speed. Human error is prevented by bringing a standard to the folding and sewing process. Faster production and error-free production reduces the cost. In addition, the sewing process can be done with only one user, so the number of employees is reduced.Description Of Figures

[0031] In the right folding section(3) or the left folding section(4), the width of the lower holding beam(7) is greater than that of the upper holding beam(8). Due to the fabric thickness of the folded fabric during the folding process, the width of the upper holding beam(8) is kept less in order to ensure fold alignment.

[0032] After the folding is completed, the compression beam(9), the lower folding beam(10) and the upper folding beam(11) are pulled into place and the lower holding beam(7) and the upper holding beam(8) come together to release the folded waistband end. On the folded end of the waistband, the transport beam(6) comes from the sewing section.

[0033] When the transport beam(6) arrives, the lower holding beam(7) and the upper holding beam(8) are pulled backwards by the piston(14) movement of the carriage(16) on the rail(15). In this case, the folded waistband end remains on the transport beam(6). The transport beam(6) carries the folded waistband end to the sewing section(5).

[0034] In the sewing section(5) the folded waistband end is sewn by the known method of the technique. After sewing, the user can repeat the process in the right folding section(3) or in the left folding section(4) to sew the waistband end at the other end of the trousers.

[0035] The lower holding beam(7) and the upper holding beam(8) developed by the invention can be combined into a single piece in the form of a U-shaped slat, so that it can also operate as two slats standing at a fixed interval.

[0036] Instead of the lower folding eccentric shaft(12) and the upper folding eccentric shaft(13) developed with the invention, other piston designs known and used in the art can be used.
