How to repair the thread of the industrial sewing machine sewing to the no load place?

Parts with cut lines. There is no cover of cloth behind the gap. The wire is in direct contact with the machine parts.

Check whether the needle is in good condition, see if the hook has burrs, and see if the needle plate hole is smooth. Then look at the machine to feed the cloth teeth. Whether it has become a sharp tool for cutting the thread!

The empty seam is broken, and there is no cover of the cloth).

Changed presser feet. (The movement of the presser foot is limited, and when going downhill, it is directly slipped, and the needle hook and thread are not fully matched) Maybe your product has exceeded the thickness that the machine can bear. Or let the hook pull the loop back a little.

Any sewing machine is inseparable from the four elements! Needle hook cloth!

What is going on with the sewing machine running empty line, hello dear, first, the reason for the empty needle of the sewing machine: Sun He 1, the thread end will be clamped off if it is stuck in the shuttle bed; 2. The needle is incomplete and bent, resulting in broken thread; 3. There are burrs in the needle plate holes; 4. The lockstitch sewing machine looks at the tip of the shuttle. Second, the solution of the empty needle of the sewing machine:

1. Wrap a circle on the needle when threading; 2. Replace the damaged needle. The method of coil stitching is very different from ordinary hand sewing. In the simplest hand-stitching of the Zelu school, the sewer ties a thread in the small eye at the end of the needle, and then threads the needle and thread completely through the two pieces of fabric, from one side to the other, and back to the original side.

There are many reasons for the thread breakage of the sewing machine, and the common faults are the line, the presser foot is not adjusted well, the gap between the shuttle bed and the needle tip is too large, the thread will be broken if it is not synchronized, the thread will be broken if the fabric is too thick or too thin, and the needle hole of the bur will be broken if the needle hole is too sharp.

The solution to the presser foot is not adjusted: when there is no foot in the pressure adjustment team, there is friction between the side of the presser foot and the needle, and the presser foot should be shaken from side to side to see if it will touch the needle when adjusting the presser foot.

The gap between the shuttle bed and the needle tip is too large: the distance between the shuttle hook and the needle groove should be millimeters, and it is easy to break the needle if it is less than millimeter.

The solution to the fabric is too thick: tighten the screws on top of the presser foot to make it have a certain amount of pressure. The fabric is too thin, and the presser foot can break the fabric when sewing.
