Panel 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.
Panel serging

Basic Level of Technology• The basic level of technology for trouser panel
serging is :1. A 2/3/4- thread overlock machine with manual
handling of fly wheel for lifting the needle.2. The operators can be skilled or semi-skilled.3. Placement of fabric on machine bed should be at
correct width position.4. Operator needs to pay more attention while
sewing to maintain required and consistent width.

Intermediate level of technology
• The 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.
Intermediate level of technology
• 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.

• 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.
Highest Level Of Technology
Highest Level Of Technology
• A 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.
Highest Level Of Technology
• The 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 Technology
• We assume: Target production-1600trousers/day• Cost of labor = Rs 3000 per month• SAM value for serging both the front panels = 0.75 min• Production = 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 0.18• Cost of Machine= $ 499/- (rs.24950/)
ROI for Basic and Highest level of Technology
• Using 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 Technology
• We assume: Target production-1600trousers/day• Cost of labor = Rs 3000 per month• SAM value for serging both the front panels = 0.30 min• Production = 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 0.07• Cost of Machine= $ 30000- (rs.1500000/)
• ROI calculations for Basic and Highest level of Technology
• Formulas to be used:• Depreciated Value(DV) = NBV/{1+DR/100}n• where NBV = Net Book Value;• DR = Depreciation rate • n = Number of years• ROI for any year= [CM Price from total machine - total
operator salary till that year] ÷ Depreciated value of total machine, expressed as a percentage
