The greatest test of courage on earth is to bear defeat without losing

of fibre properties which can influence
the quality of the yarn. A textile fibre is a peculiar object.
Fibre
properties vary very much within the lot. Optimal conditions can be obtained
only through the
mastery of the rawmaterial. Therefore fibre testing is very
very important.

THEORY OF
CARDING
Reading without thinking is like eating without digesting
High production card would not have been
possible without the Metallic card clothing. Moreover
the demand for high
production and high quality from carding machine put wire manufacturers under
pressure
to improve their design continuously to meet the requirements.
Modern metallic wire is designed for
optimum carding performance during the
processing of many tonnes of fibre at the highest proudction
rates possible,
and with the least amount of maintenance.

With the use of more sophisticated, high production

more and more complicated Pneumatic controls are necessitated. To have minimum
breakdowns and reliable performance with minimum failure, in other words, to
have good quality products,
the compressed air supplied to the machine
should be of the highest order, both in QUALITY and QUANTITY.
