Specifications of Slitting Machine

Slitting machine is required to slit and rewind the positive and negative electrodes of

lithium ion cells, aluminium foils, copper foils and separator films. The active

material coated electrodes, foils and separators will be in a continuous form. As per

the requirements, different widths of these materials have to be sized. Gang shear

slitting knives are to be used to slit the materials. Electrodes and other materials

available in the roll form from unwinding part should pass through the pre-set shear

knives continuously and after slitting should be wound in take-up roll in the

rewinding part. The machine should be capable to slit the materials into maximum

three finished width and minimum one finished width in one setting. The slit

electrodes/foils/separators must be rewound on separate take up shafts at the rewind

end. The rewound materials after slitting should be free from wrinkles and burrs.

Lubricants used in the machine should be suitable for dry room conditions where

relative humidity is less than 0.5%.

1 Introduction

Vikram Sarabhai Space Centre (VSSC) is responsible for realization of Launch Vehicles of

ISRO. Realization of flight sub-assemblies which involve integration (mechanical and

electrical) and check out of all launch vehicles of ISRO are presently being carried out at

VSSC. The activities are carried out using in-house facilities located in Trivandrum, Kerala.

Based on the demand for launch services of PSLV, it is proposed to increase the launch

frequency of PSLV to 8 10 launches in a year. To meet this demand, it is proposed to

outsource the integration & testing of some of the PSLV sub-assemblies to industries

who can carry out the integration & testing activities at VSSC facilities. The mode of

operation will be GOCO-Government Owned Company Operated. All the required

facilities will be provided by the department while the identified activities have to be

carried out by the industry.

2 PSLV

Polar Satellite Launch Vehicle is a launch vehicle developed and operated by the Indian

Space Research Organization (ISRO). It was primarily developed to launch Indian Remote

Sensing (IRS) satellites into Sun Synchronous Polar Orbits (SSPO). It has proven its worth in

launching variety of satellites into SSPO. Further, it has demonstrated its capability for Geo-

Transfer missions and used to launch small-medium sized payload satellites into

Geostationary Transfer Orbit (GTO) and planar orbits having different inclinations. PSLV

has the capability to launch 1750 kg in SSPO at 622 km and 1425 kg in sub GTO mission

(280 x 21000 km).

With the repeated successful missions over the years PSLV has proven to be versatile and a

reliable operational launch vehicle of ISRO. PSLV has a full-fledged end-to-end launch

service management and has launched numerous foreign and Indian satellites including

several dedicated commercial launches. PSLV has proven its worth in launching a variety of

satellites equipped to perform wide range of applications viz. communication, geographical

survey, navigation, inter planetary missions etc. PSLV has successfully launched

Chandrayaan, Mangalyaan and Astrosat missions, which demonstrated Indias capability and

placed the country among leading space faring nations of the world.

Currently PSLV has three operational variants as described below.

Versions of PSLV

Designation Variant Description

PSLV Generic Core vehicle with six numbers of S9 strap-on boosters

PSLV XL XL Core vehicle with six numbers of S12

PSLV CA Core Alone Core vehicle without any strap-on boosters



PSLV is a four stage vehicle with alternate solid and liquid propulsion modules. It has a total

length of 44 metres and lift off weight of approximately 300 tones. The first stage employs

solid-fuel rocket booster (S 139) and six strap-on motors (depending on the variant). The

second stage is powered by Vikas engine which uses Earth storable liquid propellants. The

third stage uses solid propellant. The fourth stage has a twin engine configuration with liquid

propellants. The Satellite or payload is mounted over a Payload Adaptor and is covered using

Payload Fairing which protects the spacecraft and Vehicle Equipment Bay during the

vehicles ascent phase through the atmosphere.

2.1 Sub-Assemblies of PSLV

The following are some of the major sub-assemblies of PSLV that are currently being

realized by VSSC.
