TRADITIONAL PREPARATION
Carding
is, within all the textile operations, one of the most demanding
on the fibres.
By using a proper type of preparation, it is possible to reduce,
as much as possible, the stress involved.
More over, the processing of blends of different fibre types
and/or colours requires operations of homogenisation over
large quantities.
The different steps of this part of the process call for specific
equipments.
|
> LOADING AND PRE-OPENING
- The Bale Tipper
(BAS) is designed for removing bindings and wrappings from
bales and for the easy loading of one or up to three bales, in
side-by-side arrangement, onto a conveyor or a machine.
- The Feed Table
(TBL) is used for the regular forwarding of bales towards
a bale breaker by means of an endless metallic or antistatic Transilon
conveyor.
- The Volumetric
Bale Breaker (CHV) is a textile fibre opening and blending
machine designed for the regular feed of an opening machine. It
has the required robustness for opening of compressed bales at
the beginning of a preparation line.
- The Wide Bale Breaker
with metallic Lattice (OBT) is a highly productive machine
which is capable of opening, simultaneously, several compressed
bales, assuring the mixing of the various bales in course of the
process.
> OPENING, CLEANING AND BLENDING
The Intermittent
Beater "SHAKER" (SHA) is designed for cleaning (de-dusting),
opening and blending the textile fibres. The Shaker can process
cotton wastes, hairs, jute as well as wool and synthetics.
>
OPENING AND BLENDING
- The Fearnought
Picker (LPC) is a high production machine for perfectly preparing
the textile fibres for blending and carding, thanks to its 3 carding
group arrangement on the swift and its delivery doffer.
- The Picker
(PIC) is mainly designed for opening synthetic fibres. It
is perfectly suitable for long fibre opening in the semi-worsted
process.
>
BLENDING, STORAGE AND HOMOGENISATION
- The Mobile
Bin Emptier (VID) can be used to serve several storage bins.
Its purpose is to perfect the blending process by taking vertical
slices from the pile of fibres laid down in horizontal lays.
- The Automatic
Self -Emptying Blending Bin (CVA) with fixed emptier and conveying
bottom lattice can be simultaneously filled and emptied in continuous
duty. It is recommended for small size blends and can also be
used for the continuous feed of cards and carding sets.
>
OILING DEVICES
- The Oiling
Table (TBE) and Oiling Tube (TUE) are designed for
the addition of water, oil or anti-static emulsions to the fibres.
- The Oiling
Preparation and Storage Units (ENS) are fitted with metering
pumps for the accurate and even distribution of the flow of oiling
product on the fibres.
>
METAL DETECTOR
The Metal
Particles Detector and Remover (DMX) reduces, to a great extend,
the risk of having a metallic foreign body running through the
card with all the damages it causes to the card clothing. Ferrous
as well as non-ferrous metallic bodies are detected and removed
without having to stop the line.
>
PNEUMATIC CONVEYING
To go from
one operation to the next, HDB can supply the complete inventory
of pneumatic conveying equipment :
- Fans
(VLR)
- Pipe
switches (EMB)
- Condensers
(CDR)
- straight
or elbow tubes,
as well as
fixed or telescopic cyclones or auto-gyrators for
the fibre distribution into the storage bins.
>
CENTRALIZED CONTROL
The Video
Synoptic ensures the centralized control of the complete preparation
process with visualization of the circuits on a screen. All the
machines and circuits are controlled with the help of a computer.
