Furthermore, sewing machine assemblies for stitching/sewing items known in the art are commonly known to include sewing machines operatively connected with mechanical gadgets such as folders for feeding and folding the items to be stitched/sewed during the sewing operation for obtaining various aesthetic patterns. Such sewing machine assemblies are of course operable in connectivity with electrical means for automated operation.
However, it has been observed over the years that stitching operations need to be performed in varying combinations of rotational directions to obtain aesthetic patterns of varieties with precision and strength. For example, during sewing operation, various combinations of say vertical and/or horizontal steps of stitching are required to be implemented to obtain varieties of stitching patterns with precision and strength, on the item to be stitched, so that the final product is appealing and has broad market value as well as longevity. Furthermore, high production efficiency and succinct operation are coveted to ensure such varieties and broad market value as well as longevity. Unfortunately, sewing machine assemblies known

in the art are far from being satisfactory, so far as their adaptability to performance of sewing operation in various combinations of rotational directions during sewing is concerned.
Research is on for a considerable period of time to design sewing machine assemblies which are adaptable to performance of sewing operation in various combinations of rotational directions during sewing. Research is on to decipher a methodology for performing such sewing operation as well. Actually such assembly and method of its operation can be implemented by succinct sewing operation and high production efficiency. These ensure broad market value as well as longevity and public acceptance of aesthetic patterns on stitched products. Significant achievement in that view of the matter is yet to be achieved.
Accordingly there was along felt need to design a sewing machine assembly for stitching/sewing items which are adaptable to performance of sewing operation in various combinations of rotational directions during sewing whereby aesthetic patterns of variety, strength and precision on stitched products are obtained and obviously, succinct operation, high production efficiency, broad market value as well as longevity and public acceptance of aesthetic patterns on stitched products are ensured. There was a long felt need to decipher a methodology for such stitching/sewing operation as well.
The present invention meets the aforesaid long felt needs.

The sewing machine assembly in accordance with the present invention is preferably adapted to be run in the usual way in an automated mode by conventional electrical means.
Preferably, the folder means in accordance with the present invention include front folder, rear folder and supplier between front folder and rear folder. More preferably, the folder means include a mounting plate, a guide plate and extending channels. The folder is adapted to shift the item to be stitched longitudinally and/or laterally and/or angularly simultaneously with sewing operation. More preferably, the folder shifts the sewing item through an angle of 90° as and when required during the course of sewing operation to obtain the desired aesthetic pattern.
The method of stitching an item according to the present invention, by applying the sewing machine assembly as described hereinbefore broadly includes stitching the sewing item at one place in a particular direction which is first step, followed by applying the folder means to shift the position of said item in the desired direction(s) and repeating the first step. Thereafter, all these steps are repeated till the desired aesthetic pattern is obtained. Thus, desired aesthetic patterns of varieties are obtained with precision and strength ensuring longevity, by various combinations of rotational steps of stitching. The rotational steps may be longitudinal and/or lateral and/or angularl simultaneously with sewing operation. More preferably, the folder shifts the sewing item through an angle of 90° as and when required during the course of sewing operation to obtain the desired aesthetic pattern. The item to be stitched may be jeans/apparel.

To illustrate how the present invention is effective in achieving its objectives, the following non-limiting comparative example is provided below which is based on results obtained from trial performance.
COMPARATIVE EXAMPLE :
A jeans/apparel was stitched applying a conventional sewing machine assembly and a stitched product P1 was obtained. Several such products (all named P1 for convenience) were obtained for comparison by running the operation several times.
A sewing machine assembly was designed according to the present invention by operatively connecting a sewing machine with the folder means. A jeans/apparel was fed by virtue of the folder means. The jeans/apparel was stitched at one place in a particular direction, this being the first step of stitching. Then the direction of the whole jeans/apparel was moved with the help of the folder to angle of 90° and the first step repeated. The whole process comprising of these two steps was repeated several times. The stitched product P2 was obtained. Several such products (all named P2 for convenience) were obtained for comparison by running the operation several times.
It was found that P2 were far more aesthetically appealing, more strong ensuring longevity and also had high market value and more public acceptability than PI. Not only that, cost of production of P2 was found to be reasonably less. Furthermore, the pattern in P2 could not be obtained by running the conventional sewing machine assembly despite repeated efforts. Also, succinct operation and high productivity were noticed in running the sewing machine according to the present invention and the number of products(P2) were also high from the same number of operations.
The aforesaid comparative example illustrate by way of example how effectively the present invention achieves its objects. The surprising technical advancement and economic significance achieved by the present invention was hitherto not conceived or achieved by persons skilled in the art from existing knowledge.

By way of example the sewing operation according to the present invention is done as follows as will be understood by persons skilled in the art:
a)The power switch is turned on. The foot lifter pedal is depressed and the work is pressed under the pressure foot. Thereafter, the foot lifter pedal is released. The machine starts running when the treadle is stepped down.
b)After sewing the work, the work is moved to the thread trimmer to make blank stitches and the thread is cut with it.
c) The upper thread tension is adjusted by turning the tension nut. Then, the lower thread tension is adjusted by turning the tension nut.
d) The pressure foot pressure by turning is adjusted by turning wing nut so that the pressure is not just enough to feed the work positively and keep the work from slipping. If the machine is being used with the puller attached , depending on works, the puller pressure can be adjusted as appropriate to the work by turning the pressure adjust screw. Further, the actual stitch length will vary depending on the type and thickness of material being used.
