Industrial Sewing
Machine
Mechanical Engineering Research &
Development Organisation, Ludhiana, Regional Centre of the
central Mechanical Engineering Research Institute, Durgapur
has Developed a 2 needle 5 thread safety stitch Industrial
Sewing Machine of capable running at 5500 stitches/minute.
The machine is ideally suitable for wowing
all types of closing seams of different garments and hosiery
goods. The following type of operations can be performed simultaneously
and continually with this machine.
i. Stitching
'Closing seams' with double chain lock stitch, type 401.
ii. Edge
trimming for equal margin from seam.
iii. Over
edging 'Trimmed edges' with three threads over lock stitch
type 504.
Areas of Applications:
The machine is ideally suitable for wowing all types of
closing seams of different garments and hosiery goods.
Advantages:
The machine can be easily converted into
1 needle, 3 thread overlock machine for only seaming operation
or 1 needle 2-thread machine for only hemming operation. Most
of the critical components of these machines have been kept
same to achieve standardisation and reduce cost of production.
Apart from the design of the machine,
the development of complete production tooling for the commercial
manufacture is one of the unique features of the development
of this machine.
Stage of Development:
Fully developed and available commercially.
Inputs required:
C.I. Body of the machine, M.S. rods, S.S. wooden stand,
etc. are some of the raw materials required.
Plant and Machinery Required :
Cylindrical grinder, centreless grinders,
horizontal internal grinder, vertical internal grinder, surface
grinder, honing machine, face grinding and lapping, capstan
lathe, horizontal milling machine, vertical milling machine
radial drill, turnet drilling machine, generator set 100 KV,
painting plant, electroplating plant, and heat treatment plant
etc.
Economic Data:
Plant & Machinery ( Rs.) will cost around 25 lakhs
approximately.
