併縫機及其布邊裁切傳動裝置 Sewing machine and its edge cutting transmission device

本發明係有關一種併縫機,尤指一種併縫機及其布邊裁切傳動裝置。 The invention relates to a parallel sewing machine, in particular to a parallel sewing machine and a cloth edge cutting transmission device thereof.

併縫相較於一般車縫來說算是較為鮮少,其主要是將兩塊布料相互搭接後再進行車縫,兩塊布料疊合的寬度必須與縫紉機縫合的寬度相當,才能確保縫線縫紉於疊合的區域,而布料疊合的寬度往往需透過作業員於布料送入壓布腳之前進行調整;然而,這種操作方式需仰賴作業員的縫紉經驗及熟練度,且市面上縫紉機台種類繁多,對應不同機種勢必要有不同的調整方式;因此,即便是縫紉經驗豐富的作業員都無法準確地將布料疊合的寬度調整與縫紉寬度相當。 The seam is relatively rare compared to the general sewing. The main reason is that the two fabrics are overlapped and then sewn. The width of the two fabrics must be the same as the width of the sewing machine to ensure the stitching. Sewing in the overlapping area, and the width of the fabric overlap is often adjusted by the operator before the cloth is fed into the presser foot; however, this operation depends on the sewing experience and proficiency of the operator, and the sewing machine on the market There are many different types of machines, and different adjustment methods are necessary for different types of machines; therefore, even a worker with experienced sewing experience cannot accurately adjust the width of the fabric overlap to the sewing width.
