What features do I need in a sofa sewing machine?

In the twenty-first century, mankind continues to progress, people's lives and requirements continue to improve, the manufacturing industry is faced with rising labour costs, sofa belongs to the labour-intensive industries, the impact is more severe, high-efficiency industrial sewing industry is the vast majority of sofa factories astute choice. Most sofas are leather sofas, whether it is the leather belt is PU leather, the material is more expensive, can not be wrong (clothing industry if sewing problems, can remove the line to re-sew, leather sewing there will be pinholes, unless the original hole can be according to the original hole of a needle to sew back, or can only be scrapped, so high-end sofa factories on the requirements of the sofa sewing machine are relatively high.
Most of the industrial sewing machines used in sofa factories are thick material sewing machines, long arm sewing machines, thick thread sewing machines, which generally have the following functions:
I. Three-synchronous integrated feeding function: the needle, presser foot and feeding teeth drag the leather forward together to ensure that the upper and lower layers of leather of the sofa cover are not shifted;

2. Automatic presser foot lifting function: the presser foot of the thick material sewing machine will be lifted automatically when releasing the leather material, which saves time and effort;

3. Automatic backstitch function: In order to prevent the thread from falling out at the beginning and end of the sewing machine, there are at least 3 backstitches at the beginning and end of the sewing machine;

4. Automatic thread cutting function: cut off the top thread and low thread automatically after sewing, saving time and labour, but these functions are only limited to the sofa cover sewing machine with thick material, the sewing machine with extra thick thread for pressing the big thread is seldom with this function (the thread is too thick, the blade can not cut it);

5. Automatic needle stop function: When the sofa cover is turned halfway, the needle stops at the lower needle position to fix the leather and prevent the needle from being shifted, resulting in inconsistent stitch length. After sewing, the sofa sewing machine needle stops at the upper needle position, and the operator can take out the sofa cover directly;

6. Straight sewing auxiliary function: when stitching operation needs to be equipped with a pneumatic gauge to ensure that the seam is straight and the distance between the seam and the edge remains consistent. Pressing the line needs to be fitted with a centre presser foot to ensure that the bright line and the seam allowance of the pieced seams remain consistent;

7. The sash traction function: this function is generally thick thread double needle sewing to be dedicated. In order to increase the firmness of the seams or increase the sense of three-dimensional, double-needle sewing in the leather below the increase of a sash, play the role of reinforcing rib;

8. The second clamping function: this function is extra thick thread sewing machine/pressure big line sewing machine special, sofa cover over-sewing parts often by 3 to 6 layers of leather superposition, the thickness of the instantaneous increase of 3 times, a single clamping device can not be the bottom line up, this time you need a second clamping device to the bottom line up;

9. Automatic thread dragging functions: this function is special for extra thick thread sewing machines/pressure big thread sewing machines, and only high-end sofa factories with very high requirements on sewing quality will use it. During the sewing process, the lower the thread roll of the bobbin, the smaller the tension will be, which will affect the effect of the bobbin winding of the thick thread sewing machine, so it needs a kind of bobbin balancing device to ensure that the tension from the thread roll is always the same.
