What is handbag out of line?

Handbag special is a work of designing the shape of
handbag components with paper lattice as materials according to the original
board of handbag (or design drawing and photographic drawing), and marking
various marks on the paper lattice components to indicate the handbag making
method.

Handbag special mainly refers to the work of manual
paper making, design, product development, computer special and so on. Handbag
special mainly refers to a professional term of handbag factory, and it has the
same meaning as the paper pattern of clothes in the garment factory. In other
words, the designer of the bag outlet lattice will provide the corresponding
design drawings and physical version according to the needs of customers. In
the operation of dividing different controls with paper, it will usually be a
plane presentation, and the leather will be continuously opened according to
the shape of the paper lattice, and then the sewing, table top and other
related processes, You can meet the expectations of customers and make a
finished handbag you really want.

·Special order

First out of the main case, then out of the secondary
case. The paper grid that can determine the shape or size of other paper grids
is called the main grid. The secondary grid is a paper grid whose shape or size
depends on other paper grids.

For ordinary handbags, the width is the main grid and
the circumference is the secondary grid; The back frame is the main case of the
front frame; The front bag width is the main grid of the front bag
circumference; The side pocket width is the main grid of the side pocket
circumference.

The special order of general handbags is: back, front,
large bottom, zipper, front, front, side and side. According to the out of grid
order, measure the paper grid with the paper grid to figure out the shape of
each paper grid, make triangular notches and holes according to the structure
of the handbag, and write various text marks on the paper grid until the paper
grid is finished.

Note that the length of a paper outlet should be added
to the paper outlet according to different needs.

·Inspection method of paper lattice

Inspection method for shape and size of paper grid:

Fold the paper grid in half along the coordinate axis,
and the shape triangular notch shall coincide, otherwise it is unqualified.

Shape and size inspection of paper grid:

Compare the paper grid before enlargement with the
actual handbag, and the coincidence degree shall not exceed the maximum
allowable error value.

Inspection of triangular notch of paper grid:

It mainly tests whether the triangular gap has made
its four functions completely; Whether the size of triangular notch is
consistent.

Matching degree inspection between paper grids:

Measure the paper grid with the paper grid and check
whether it conforms to the structural law.

·Mark on the paper grid of handbag

Paper mouth of paper grid:

The paper mouth is in the paper grid. The paper mouth
is extra long and can not be seen from the surface of the handbag. It is used
for edge connection. The more sticky things, the longer the paper mouth.

Triangular notch of paper grid:

The triangular notch in the handbag paper grid
indicates the mark of the handbag making method. It is the inspection standard
of whether the single piece paper grid is correct or not. It is the inspection
standard between paper grids and whether the complete set is matched or not. It
is the inspection standard of the turning method and its turning technology.
For different handbags, due to different structures, different paper lattice
shapes and different paper mouth lengths, the position and number of triangular
notches must be different. But the triangular notch of the paper grid is the
same size.

Hole position of paper grid:

The triangular notch of the paper grid is a symbol
marked on the edge of the paper grid to indicate the structure of the handbag.
For complex handbags, on large components, one or several bags are also
designed to avoid the monotony of their shape and increase the practicability
of handbags. To determine the position of a bag inside the paper mouth of the
component, the punching position is required. You can’t make a triangular gap.
Determine the position of various hardware and plastic ornaments, also
expressed by hole position. Generally, the hole position of the paper grid
shall be surrounded by a pen, and its purpose shall be marked.

Text mark of paper grid:

The text mark on the paper grid, including the article
number of this handbag. Name and quantity of paper grid. The material cutting
method is marked with transverse grain or straight grain. Indicate the maximum
length and width of this paper grid. The maximum data width is multiplied by
the maximum data length. For the function of the hole position and the three
notches in the part, it is generally necessary to circle it with a pen and mark
its purpose.

Handbag is a special technical work with high accuracy
requirements. In terms of raw materials and structure, we should pay attention
to the following items when measuring the length at ordinary times:

For the requirements of the measured object, it should
be mainly placed on the desktop, and in terms of measuring the main length of
its natural state, it is absolutely not allowed to tension and pull the
physical material, because many of the main handbag raw materials mainly have
the function of scalability, otherwise the length in measurement will be longer
than the physical material.

When measuring the distance between two parallel
lines, we should ensure that the two parallel lines should be generally
perpendicular to the steel ruler, and can be fixed on a parallel line at the
starting point of the steel ruler, while at the other end, it can be moved on
the other parallel line, and the last shortest scale is a distance between the
two parallel lines, so it will be relatively short in terms of vertical line
segments.

The line position at the steel ruler and the starting
point should coincide very high. If the line position can not be seen in the
rubber bone bag, we should start at the beginning of the bone center, and the
end point at the steel ruler to the bone center or the opposite line position
shall prevail.
