Problems solved by technology

For example, there is a method in which the left and right sides of the front fly fabric N are folded back using the stitches n1 and n2 as creases, and a top stitch formed near each crease is formed. Sewing requirements, but the existing sewing machine can not carry out the sewing
[0007] Therefore, the formation of the decorative line must be performed by other sewing machines or by hand sewing, and the sewing of the front placket cannot be efficiently performed.

[0121] Next, a first embodiment of the sewing machine according to the present invention will be described in detail with reference to the drawings. In this embodiment, a sewing machine suitable for sewing the front fly material N to the body material K on the front side will be described.

[0122] [sewing process]

[0123] First, based on figure 1 (A)~ figure 1 (I) The sewing process at the time of sewing the front fly fabric N to the body fabric K will be described.

[0124] First, prepare the front body fabric K ( figure 1 (A)), place the front placket fabric N on the chest of the body fabric K ( figure 1 (B)).

[0125] Next, form the first and second stitches n1, n2 ( figure 1 (C)). In addition, in figure 1 In (C), it is shown that the lower ends of the first and second stitches n1 and n2 are close to each other, but actually the first stitch n1 and the second stitch n2 are formed in parallel with a slight gap between them. In addition, after forming the fir...

Abstract

The present invention carries out the sewing of the colorful front placket. The sewing machine includes a cloth presser that holds the cloth of the clothing body and the front placket cloth, a cloth moving mechanism that arbitrarily moves the cloth presser along a plane on which the cloth of the cloth body is placed, and a sewing needle vertical movement mechanism that moves the cloth presser A cutting mechanism for forming a slit in a fixed direction in a cloth body and a front placket fabric held by the cloth presser, and a control device for controlling the cloth presser, The cloth moving mechanism, the needle up and down moving mechanism and the cutter mechanism, the control device controls the cloth moving mechanism and the needle up and down moving mechanism to form a first stitch and a second stitch, controls the cutter mechanism, The sewing machine is provided with a first folding back mechanism that folds back the front placket cloth along the first stitch and a second folding back mechanism that folds the front placket cloth along the second stitch .

Description

technical field [0001] The present invention relates to a sewing machine for sewing a front fly. Background technique [0002] Existing sewing machine 1000 for sewing the front door such as Figure 22 As shown, it is equipped with: a sewing needle up and down movement mechanism 1100, which forms two stitches from the collar downward for the front placket fabric N arranged on the chest of the body fabric K; A slit along the stitches is formed between them; and a cloth presser foot mechanism 1300, which presses the body cloth K and the front door cloth N from above, and makes the body cloth K and the front door The flap N is moved (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2005-110963 [0004] In addition, the sewing of the front placket has the following processes: Figure 23 (A), Figure 23 As shown in (B), the front placket fabric N is arranged on the chest of the body fabric K; two stitches n1, n2 ( Figure 23 ...
