    • The present invention provides a thread feeding device of a decorative stitching sewing machine. The thread feeding device feeds a needle thread, an upper looper thread, and a lower looper thread in the amounts required for sewing one stitch such that the position of a stitch looping point of the threads changes. The thread feeding device includes: a thread accumulator 500 having thread accumulating elements 13a to 13d and 14a to 14d which measure the thread accumulation amounts of predetermined lengths of the needle thread, the upper looper thread, and the lower looper thread, and thread accumulation amount control elements 15 to 18 which adjust the amounts of the threads required for sewing one stitch in an increasable and decreasable manner within the range of thread accumulation amounts of predetermined lengths at the time of fabric feeding, and which release the threads to a stitch forming device when a stitch is formed; a thread feed drive mechanism 600 which drives each of the elements; and a thread feed control unit having a program which dives the thread accumulation amount control elements for each stitch to feed the threads in an increasable and decreasable manner so as to increase or decrease the threads within the range of a total thread feeding amount that is maintained constant, including a fabric feeding amount, a fabric thickness and an overlocking width, thereby to change the position of the stitch looping point of the needle thread, the upper looper thread, and the lower looper thread, thus controlling the decorative stitching according to a stitching decoration pattern.

    • Duvet inserts are provided with at least two chamfered or beveled corners to prevent overhanging of the corners. Additional drag caused by the overhanging corners and frequent handling of duvet inserts by the corners causes migration of fillers contained therein and this is mitigated by the chamfered corners. Again, sectional barriers, preferably by stitching zigzag, waves or triangle wave stitches along the periphery of duvet inserts are capable of minimizing migration of fillers. Furthermore, quilted or line stitches on at least two corners can also be provided to contain the fillers. Duvet inserts of the present disclosure are durable and chamfered corners provide a neat and tailored look thereby enhancing bed presentation and also avert accidents such as tripping over the overhanging portion.
    • 羽绒被镶嵌件具有至少两个倒角或斜角,以防止角部突出。 由拐角引起的额外的阻力和由角落频繁地处理羽绒被插入物引起的填充物中的填料的迁移,并且这被斜角所减轻。 同样,优选通过沿着羽绒被插入物的周边缝合锯齿形,波浪形或三角形波迹线的截面屏障能够最小化填料的迁移。 此外,还可以提供至少两个角上的绗缝或线缝以容纳填料。 本公开的羽绒被插入件是耐用的,并且倒角提供了整齐和定制的外观,从而增强了床呈现,并且还避免了诸如在悬垂部分上跳动的事故。

    • A hidden seam rehemming method for jeans, comprising steps as follows: (a) cutting down a part with desired length including the hem from the jean to be shortened, and cutting down the hem with a first seam allowance from the cut-down part; (b) taking out threads from the hem and unfolding the hem such that three rows of needle holes in the hem appear; (c) sewing the unfolded hem with a remaining part of the jean along the upmost row of needle holes in such way that the outside surface of the unfolded hem contacts the outside surface of the remaining part; (d). folding the first seam allowance of the hem and a second allowance of the remaining part toward the inside surface of the jean; (e). pressing the first and the second seam allowances with nail or iron such that the seam allowances lie against the inside surface of the jean; (f). folding the hem along original fold marks thereof such that the three rows of needle holes are superposed again and sewing it from the outside surface along the joint seam between the hem and the remaining part.
    • 一种用于牛仔裤的隐藏缝制方法,包括以下步骤:(a)将包括来自牛仔裤的下摆的期望长度的部分切割成缩短,并且从切割部分以第一缝隙限制下摆; (b)从下摆线取出螺纹,展开折边,使下摆中的三排针孔出现; (c)沿着最上排的针孔将剩下的一部分牛仔裤缝合在展开的褶边上,使得展开的折边的外表面与剩余部分的外表面接触; (d)。 折叠下摆的第一缝隙余量,剩余部分的第二容限朝向牛仔裤的内表面; (e)。 用钉子或熨斗按压第一和第二接缝配额,使得接缝余量位于牛仔裤的内表面上; (F)。 沿着其折叠标记折叠折边,使得三排针孔再次重叠并且沿着下摆和其余部分之间的接缝从外表面缝合。
