4. Introduction.
After the cutting department the fabrics
come to the sawing department.then the
bulk is start to sawing.in the sawing
department the garments going though
production system and then the saems and
stiching.
6. Garment production system
1. Make though
system
In this system an
operator makes right
through one garment
at one time.
7. Garment production system
2. Coventional bundle system
Sewing machines are arranged in lines.
The work flows from the central (store) area to the first machine,
from the first machine back to the store, and then on to the next
machine, and so forth.
A distributor stationed at the store is responsible for receiving and
dispatching the work.
The work in progress is in the form of bundles.
These bundles may be put on to a tray, a box, or a bag, or the
garment parts may be wrapped and tied.
8. Garment production system
3. Clump system
A worker collects a clump of materials from the worktable and carries
out the first operation.
After he has completed his part of the work, he returns it to the
table.
A worker for the second operation then continues the work and so
on.
The process is ' collection - work -return' continues until the whole
garment has been assembled.
9. Garment production system
4. Progressive bunddle system
Each operator receives a bundle, does his work, reties the bundle and
passes it to the next operator.
There is a storage facility such as rack, bin or table for storing the
inter-process work between each operation.
The work is routed by means of tickets.
This system is the most widely used system in the garment industry
today. It is used in shirt factories, jeans factories, jacket factories, etc.
10. Garment production system
5. Flexible flow system
A section of sewing operators, each with a supply of work in a rack at the side, work at
an engineered work place.
The machines are laid out in such a way that a flow of work can be planned using the
correct number of operators in sequence.
For style A garments, the work distributed after operation 1 can be distributed to the
two operators performing operation 2. On completion, the work from both workers is
then sent to operator 3. After operation 3, the work is continued by the two operators
performing operation 4 and so on.
When a new style is to be loaded on to the system, the number of operators needed
for each operation must be planned in detail to ensure a balanced output.
11. Garment production system
6. Straight line system
The manufacturing process is broken down into several
operations, which take the same time to complete.
Groups of operators are required to handle only individual
garments.
The garment parts pass from one operator to the next, until the
garment has been completely made up by one group of operators.
The central distribution unit may be a fixed table or a a conveyor
belt (its speed will be set to suit the cycle time).
12. Garment production system
7. Synchro flow system
Garment parts of the same size and color are processed
separately.
Different garment parts can be processed simultaneously for
assembling.
At the same time, collars, sleeves, cuffs, pockets, etc., from
other lines also go down a central line.
The different garment parts are then processed together to
form completed garments.
13. Garment production system
8. Unit production system
A unit production system (UPS) is a computer-controlled production line.
It is a type of line layout that uses an overhead transport system to move individual
units from work-station to work station for assembly.
All the parts for a single garment are advanced through the production line together by
means of a hanging carrier that travels along an overhead conveyor.
Production operations are completed without removing the parts from the carrier.
Automated materials handling replaces the traditional system of bundling, tying and
untying, and manually moving garment parts.
Electronic data can be collected from workstations, which provides payroll and
inventory data, immediate tracking of styles, and costing and performance data for
prompt decision.
14. Garment production system
9. Modular manufacturing system
Modular manufacturing groups operators into teams, or
modules.
The team works on one/a few garment at a time instead of
a bundle of garments.
The operators stand /sit at their stations and rotate to
different machines as they work, becoming familiar with
multiple steps in producing the garment.
15. SEAM AND STICHES
SEAM
What is a seam ?
A seam is a line where two or more fabrics are joined.
16. Seams and stiches
Types of seams
• Superimposed seams
• Lap seams
• Bound seams
• Flat seams
• Edge finishing seams
