Method For Manual Cutting Of Leather

The style of leather shoes is ever-changing, so the shapes of components are varied. There is no uniform pattern.

Before making a plan, he should first study the template carefully, explore and find the best method.

Familiar with the main parts of the template, so that when making the layout can be organized.

According to the notification of job orders, raw materials should be collected from raw materials storehouse, the area number should be checked, and the quality should be assessed.

Due to the differences in the size of the natural leather, the size of the grain, the depth of the color, the length of the fuzz, the thickness of the wool, the thickness of the leather, and so on, the leather should be collocated and divided according to the needs of the cutting, so that the leather can be set according to the "matching".

Marked disability is also known as point injury.

It is marked by the use of mercury pens, special pencils, chalks, and chalk tablets for the damage of grain, meat, hair and fur.

The surface of the meat should be marked on the corresponding part of the grain.

When marking disability, we should strive to neither expand nor reduce the area of disability, so as not to affect the quality of products or cause waste.

The leather grain is facing up and tiled on the worktable, and then the blanking sample is placed on the surface leather. According to the principle of laying and reasonable utilization of the disability principle, the plan for the next cut is determined.

The left hand presses the template, the right hand holds the pen or the pouch, and moves along the periphery of the pattern to draw clear lines.

When hand cutting, a number of help parts can be drawn together on a piece of leather, and the number of various components may also be different.

Therefore, in order to prevent errors and facilitate subsequent operation, it is necessary to indicate the size and the number of each pair of parts.

The location of the number shall be in the concealment of the parts without affecting the appearance of the product.

The number of handwriting should be correct and clear.

When the material is cut, the outer edge of the stitch should be carried out to preserve the stitch marks.

If the edges of adjacent components overlap, the center line should be cut.

If the adjacent parts overlap, the integrity of the main components should be maintained.

When the base material is cut, put the top leather grain flat on the operator's table and cut the leather with the triangle knife. The other hand grabs the bottom leather and rips it up.

The blade of the triangle knife is approximately perpendicular to the bottom leather surface, and the angle between the knife and the leather surface can not be less than 70 one 80.

The cutting edge after cutting is smooth and smooth.

Classify the cutting parts according to the number of the goods; divide the files according to the size of the sizes; after the quantity is counted, tie them up and load the material plates, and send them to the inspectors for examination.
