1Panel Serging A serger is a machine that creates the finished
seam you see on the seams of ready made garments such as side seams
in trousers, jeans, sweat shirts and tee shirts. Due to industrial
influences, you will hear people refer to what home sewers have
come to know as serging by many different terms, Overlock and
Merrow (named after the Merrow Sewing Machine Company) are just a
few.

3Basic Level of TechnologyThe basic level of technology for
trouser panel serging is :A 2/3/4- thread overlock machine with
manual handling of fly wheel for lifting the needle.The operators
can be skilled or semi-skilled.Placement of fabric on machine bed
should be at correct width position.Operator needs to pay more
attention while sewing to maintain required and consistent
width.

Intermediate level of technologyThe intermediate level of
technology for trouser panel serging is:A 2/3/4- thread overlock
machine with motor driven system for lifting the needle.It reduces
work content for operator and fatigue as the speed of machine is
higher and no manual handling of fly wheel for lifting
needle.9/30/20159
Intermediate level of technologyThe operators can be skilled or
semi-skilled.Placement of fabric on machine bed should be at
correct width position.Operator needs to pay more attention while
sewing to maintain required and consistent width.

Highest Level Of Technology
Automatic Serging Machine:An automatic single head or double
head work station with or without computer programming.An automatic
machine with or without knee lining.The machine performed serging
according to the material used.Flexible cloth guide can easily be
adjusted in height according to the material to be used.
9/30/201515
Highest Level Of TechnologyA dust extractor is equipped as
standard in the upper looper arm section where dust is likely to
gather.it helps prevent dust from accumulating inside the cloth
chip cover.The machine comes with an air-blow table,which issues a
jet of air from its air nozzles at three locations to contribute to
smoother handling of material.
9/30/201516
Highest Level Of TechnologyThe operator simply places the fabric
on the machine, and starts the machine.
The operators can be semi skilled, no need of skilled
operators.

ROI for Basic and Highest level of Technology
The decision of which machine to purchase depends on the size of
orders that a manufacturer gets and the kind of labor that is
available.
The higher we move up in the levels of technology for any
operation, greater is the productivity and consistency of
quality.

Basic Level of TechnologyWe assume: Target
production-1600trousers/dayCost of labor = Rs 3000 per monthSAM
value for serging both the front panels = 0.75 minProduction = 640
trousers per day (shift of 480 mins.)Labor cost per day = 3000/ 26
= Rs 115.40 (month of 26 working days)Labor cost per trouser =
115.40/ 640 = Rs 0.18Cost of Machine= $ 499/- (rs.24950/)
9/30/201522
ROI for Basic and Highest level of TechnologyUsing advanced
machinery also results in deskilling of labor; more is the
automation, lesser is the skill required by an operator.
Keeping all this in mind, we can calculate the ROI for the
highest level of technology and find out how effective it is for an
industry

Highest Level of TechnologyWe assume: Target
production-1600trousers/dayCost of labor = Rs 3000 per monthSAM
value for serging both the front panels = 0.30 minProduction = 1600
trousers per day (shift of 480 mins.)Labor cost per day = 3000/ 26
= Rs 115.40 (month of 26 working days)Labor cost per trouser =
115.40/ 1600 = Rs 0.07Cost of Machine= $ 30000- (rs.1500000/)
