The Building mechanism of Speed frame
is very complicated in the view of its
mechanical drive system.
So That is Why There was a big demand of
development in building motion.
Since Builder Motion has to perform so many task:
• Reduction in RPM of Bobbin (Through Shifting of Belt)
• Up-Down Movement of the bobbin Rail
• Shortening of the traverse length to make ends taper

Knowing the basics of raw material, yarn production process and the other factors influencing quality will put the sourcing manager at the same eye level as a spinner /supplier when negotiating quality issues.
As a consequence this puts the sourcing manager in the position to pay the right price for the corresponding quality level.
This kind of know-how supports a retailer enormously in his efforts to establish a reliable supply chain which is based on mutual understanding.
Cotton is a natural fibre available easily and abundant quantity. It is a most suitable fibre for textile spinning & clothing due to it’s good spinnability & human friendly characteristics. As cotton is a natural fibre hence it’s properties also affected with several other factors which create variation in fibre properties, these variations also affect spinning processes & it’s products Quality in multi dimensions. Each fibre characteristic impact individually and collectively on spinning process or at ultimate product quality. Revolutionary changes observed in last two decade in the field of spinning machineries where processing speeds greatly increased to enhance production rate. Not only production rate of spinning machines increased but speeds of it’s downstream processes also increased simultaneously which requires better quality of yarn for smooth process and without any interruption to get the maximum efficiency. Hence now it is most important to co-relate fibre properties with respect to it’s consumer process competency. In this article we will discuss the different cotton properties and it’s impact on spinning process and product quality in present prospective and will try to minimize the impact of poor fibre properties on process or product Quality through better Mixing plan selection.
Hairiness is characterized by the quantity of freely moving fibre ends or fibre loops projecting from a yarn or textile fabric (woven, knitted or non woven fabrics).
In term of measurement Hairiness corresponds to the total length of the protruding fibres in unit length of one centimeter.
Ring spinning produces yarn in a package form called cops. Since cops from ringframes are not suitable for further processing, the winding process serves to achieve additional objectives made necessary by the requirements of the subsequent processing stages.

• There are six reserve trunks which comprises
of reserve trunk flap (3), perforated partition
wall and light barrier for minimum filling
level monitoring.
• Each trunk is filled until the set pressure is
reached.
• When the pressure is reached, the controller
identifies the trunk as full and the next trunk
is filled.
• The trunk is ready to receive the material
again only when the calculated filling level
has fallen to 75%
• If all the trunks are ready to receive material,
the system switches to next trunk after a
maximum of one min even if the changeover
pressure is not reached.

• It is a combination of one spiked roll and
two saw-tooth rolls which ensures high
degree of opening and cleaning
especially of medium grade cottons.
• These rollers work in combination with
mote knives and suction hood to remove
fine trash impurities in all types of cotton
very effectively.
• Roll 1 has two separating wings. A
carding segment is installed after the first
wing. Waste is extracted directly from
the separating wings, via suction hood
i.e. a continuous suction flow removes
all contamination produced by
separation.
• Before the second separating wing, a
guide wing is situated which can be
steplessly adjusted during production. In
this way, the quantity and composition of
the waste can be regulated.
• Roll 2 (6) runs faster than roll 1 and
receives the material. Roll 2 is equipped
with a guide wing, a carding segment, a
separating wing and a connected suction
hood (7).
• Roll 3 (8), which in turn runs faster than
roll 2, is also equipped with a guide
wing, a separating wing and a connected
suction hood (9). From here the material
is extracted to the next machine.

are held open (feed).
• Upper nipper plate Zo is lowered onto
cushion plate (Zu) so that the fibers are
clamped between them (nipping).
• Combing segment (K), mounted on rotating
cylinder (Z), sweeps saw-teeth through fiber
fringe (B) and carries away anything not held
by the nippers (rotary combing).
• The nippers open again and move toward
detaching rollers (A) (nippers forward).
• Meanwhile detaching rollers (A) have
returned part of the previously drawn-off
stock (web V) by means of a (partial) reverse
rotation, so that the web protrudes from the
back of the detaching device (web return).
• In the course of the forward movement of the
nippers the projecting fiber fringe (B) is
placed on the returned web (V) (piecing).
• The detaching rollers begin to rotate in the
forward direction again and draw the
clamped fibers out of web (W) held fast by
feed rollers (S) (inside the nippers)
(detaching).
• Before the start of the detaching operation,
top comb (F) has thrust its single row of
teeth into the fiber fringe, (passive combing
by the top comb).
• As the nipper assembly is retracted, the
nippers open for the next feeding step. The
