3. The compactor machine is a tubular fabric shrinkage control
machine which can compact the fabric in length wise direction,
to provide over feed to the fabric while processing in presence of
steam, and able to control the shrinkage. In other words, this is a
process of compacting the fabric in length ways direction.

Some instructions for optimum performance:
1. Center the felt blankets on the cylinder. Ensure that all cylinders are running
parallel relative to each other. Adjust the limit switch against the edge of the felt.
2. Place the felt under tension. Upper felts tension-2 bar, Lower felt tension-1 bar.
3. raise the heated drum working temperature to 200 f| & set the speed to 11-22
yd/min(10-20 m/min)
4. Open the humidification ramp in order that felts are in a steam atmosphere.

46. Support Structure:
It consists of sturdy body sides made of painted steel, supporting
the cylinders, the mechanical part and the plant system; they are connected by means
of longitudinal and transversal cross-section. The body sides are provided with special
safety locks.
Inlet Tightener:
The inlet tightner is designed to drag the fabric to the machine with an
adequate tension. Its effect can be varied by turning the hand wheel provided.
Fabric Draw Roller:
The draw rollers receive their movement from a variable speed
motor. They deter-mine the speed of fabric.
1. The rollers are normally covered with rubber and it is most important that the
surface of the covering is always in good condition so ass to avoid slipping of the
fabric. Should this not be so then it is necessary to replace the covering.
2. The processing of fabrics treated with chemical against might involve a rapid
deterioration of the drag rolls coating.
47. Idle Cylinders:
The idle cylinders are designed to change the route of the fabric to
convey it in the right position for subsequent working.
Dancing Roller Synchronizer:
The dancing roller is constituted by a cylinder mounted
on oscillating arm, connected to a rheostat for the synchronization of the various group.
Inlet fabric Guide:
It consists of shoulders supporting a couple of adjustable spreader
rollers operated by an independent motor, and a pneumatically operated fabric centering
unit with move-able staves, controlled by border guard photocells.
Steaming Tank :
It consist of no. 1 steam delivery chamber on the fabric, made of inox
steel and complete with metering valve and on-off solenoid valve.
48. •Compacting units:
They are the real compacting units. Each unit consists of:
1. A steam heated cylinder, diameter 500 mm., made of chromium plated and
ground steel; it is complete with a rotary joint for steam feeding, a thermocouple
feeler to feel the temperature, and an effective system for the condensate
drainage. The cylinder temperature can be adjusted with the utmost (+/-2˚C)
directly from the keyboard placed on the control board, and is shown on the
display.
2. A thick Nomex – Polyester compacting felt. The double action felt centering de-
vice ensures perfect felt alignment during running. The computer controlled felt
control mechanisms automatically releases felt tension after a machine stop.
3. An adjustable position counter-roller for the fabric shrinkage control during inlet
in the compacting group.
4. An inlet element in a special non-adherent fibre (shoe) equipped with a device for
adjusting both angle of incidence and insertion length.
49. Spreader Roller
It is a spreader roller, for the selvedge unwinding and the inlet of the fabric
perfectly spread in the machine.
Scroll Roll Unit
The adjustable spreading scrolls at entry are used for open width knits and for
all fabrics that have lengthwise creases. Consists of two adjustable spiral scroll roll
driven by an independent motor.
Device for Fabric Tension Check
It consists of a cylinder combined with a special load cell sensor. It allows
synchronizing the speed between the upper and lower compacting unit, and
adjusting the fabric tension between them with the utmost precision. The
adjustment is performed directly from the keyboard placed on the control board
and is shown on the display.
50. Cooling Unit
It consists of a steel structure including a conveyer belt, the drag and tension
cylinders Of the latter, a suction chamber with a net plane for a perfect distribution of
the cooling air. The chamber is connected to a high-efficiency centrifugal electric fan.
Checking Table:
The inspection table is composed by a steel structure that supports a table that
accompanies the fabric falling from the cooling band. In this phase the operator placed
in the rolling up unit zone can carry out a check on the quality of the worked fabric and
notice possible defects.
Fabric Storage Chute for the System Non-Stop:
It consists of a j-plate for the fabric storage during the phase of roll change. It
allows removing the finished roll, and starting a new roll without stopping the system.
51. Rolling Unit
It consists of a bearing structure and a moveable trolley which supports the
rolling cylinders. The trolley sides on two rails in order to allow the perfect alignment
of a selvedge on the roll of fabric. The movement is automatically controlled and is
operated by an electromechanical actuator. The reading of the selvedge border is
performed by two photocells, whose position can be adjusted by means of a hand
wheel. The rolling cylinders are covered with vulcanized rubber for a perfect adhesion.
The roll compactedness can be adjusted by a pneumatically operated device. The
rolling unit is complete with a spreader roller, operated by an independent motor,
placed immediately before the rolling cylinders.
Steam System
It is installed in the machine. It includes a filter, an on-off valve, a pressure
gauge for displaying the line pressure and a condensate separator. It is provided with a
series of servo-operated solenoid valves to feed the different elements of the machine
and wit automatic steam traps complete with by-pass for manual drainage.
Controls
The main controls are located on the left side at the machine entry; they
include a “Touch Screen” interface and a set of buttons. The auxiliary controls are
placed on the panel at the machine exit. The emergency stop buttons are located on
the sides of the machine.
52. S) Electric Board:
The electric board is installed in the machine. It includes the electromechanical instal-
lation, electronic cards, a set of inverters and the PLC controlling the machine. It is
also equipped with protection devices, and cooling devices. All operation func-tion is
shown in the “Touch Screen” on the main control board. The machine is equipped
with a direct grounding of all the electric components and of the metal frame. The
preventive measures to ensure immunity in the presence of electromagnetic dis-
turbances have been adopted, and have been taken the necessary precautions to atte-
nuate the disturbances of an electromagnetic nature produced by the electric/
electronic system of the machine
T) Pneumatic System
It includes an on-off valve, a filter-lubrication unit, a pressure regulator and a series of
solenoid valves for the operation of the pneumatic actuators.
