Portnevsky Lecalo: what is and how to do it

You might think that modern drawing programs replaced the template, what is The tool is less convenient for drawing patterns and drawings than a computer. However, this is not the case, no large enterprise that manufactures products on the basis of templates still can do without the patterns.

Why is it needed?

This tool is used in the manufacture of parts that have in their form areas with bends, spirals, parabolas and other complex elements.

It is most often used in mass production of clothes and shoes, but it can be used in any other area where it is necessary to build a complex drawing or a correct curve (for example, in construction or in the construction of roads).

The most qualitative is the factory-made data sheet. What Copying the desired silhouette through copying paper in comparison with the accuracy of computer calculations and cutting it with a laser? The tools so produced are used to build drawings with high accuracy. Can be made of metal or plastic. Factory production of templates is more expensive than home, but the quality of finished patterns is much higher.

The tailor's pattern. What?

For high-quality production of clothing you must have a set of quality templates. It should include patterns:

1. Details of the upper part of the clothes.
2. Details of the lining, if it is provided in the finished product.
3. On the heater.
4. On duplicating materials.
5. Milling (used to apply structural elements).

This is a necessary minimum for the production of quality clothing. For tailor's work, you can make a drawing with your own hands or purchase a finished one. The material must be strong enough that you can use the tool more than once.

What is different about the pattern from the pattern

Pattern of the product is made of thin paper: tracing paper or graph paper. As a rule, it is used only once, after which it is thrown away. In addition, it has less accuracy than the pattern. This is due to the fact that the inaccuracy of the pattern can be corrected on the dummy or on the person for whom the thing is sewn.

The patterns are used mainly in large industries, where there is no such possibility. They are developed using mathematical calculations and taking into account knowledge of the structure of the human body. These tools allow you to create quality items without fitting.

How to make a template

To work at home, you can draw a loop with your own hands. This makes sense if the item is made repeatedly, for example, for an adult whose dimensions do not change, or when making soft toys for children. The manufacturing process has the following stages:

1. Removal of measurements.
2. Construction of an accurate pattern according to the specified measures.
3. Copying it to dense material.
4. Cutting.

If it is necessary to obtain a universal pattern, you can make it using geometric constructions. For example, draw two circles of different sizes and connect them with tangent lines.

When using a universal tool, it is sufficient to map out three points that need to be connected, pick up a suitable template and connect them along a curve.

The following materials can be used to make the pattern:

1. Cardboard or heavy paper (the simplest version).
2. Polyethylene.
3. Plastic.
4. Rubber cloth oilcloth.

The latter option is good because this material is available (sold in pharmacies), while it is durable, does not tear, does not crumple, easily folds, durable. The curves from this material can be conveniently drawn around due to hard edges.

It's hard to believe, looking at the tailor's templar, what is A simple invention is of great importance in modern production. However, despite the external simplicity, this is a very useful tool.
