In conjunction with direct doffer drive, the brake provides complete control during start and stop r: • • • • sequences by maintaining sliver formation. Also improves level of safety. Improved flat design - with high section modules to eliminate transverse distortion giving improved carding performance. Integral drafting system - 2 over 3 drawbox drafting arrangement reducing the number of trailing hooks offering potential to reduce number of drawframe passes in carded yarns, and in combed yarns, a significant reduction of comber waste. Improved card cleaning - total suction card cleaning system feeding to central filtration plant. Increased number of card cleaning points leading to cleaner sliver and reduced dust and fly liberation. Optional card auto leveller - high performance system providing stepless correction response proportional to sliver throughput speed. Corrects for long, medium and short term irregularities down to less than half a metre. The Hollingsworth Model 2000 Card having a rigid subframe, is delivered fully assembled significantly reducing installation time. Enclosures are interlocked with the machine drive for safety and are capable of being removed easily for servicing. Element stability, and close tolerances combined with Hollingsworth high quality clothing ensure the best possible carding performance. disc brake is interlocked with the machine . enclosures to give a high level of safety. With brake pads which can be replaced easily, the air reservoir in the feed line provides for braking in the event of an air supply failure. The brake disc is firmly secured to the cylinder weldment and has a large surface area for rapid heat dissipation. The card operator control panel, located on the right of the delivery end carries the shift/production data control unit, main control buttons and where applicable, controls for the Masterleveler autolevelling system. A graphic display with mode and fault indication is also carried on the control panel. Fault detection includes; feed malfunction, metal detection, sliver breakage, material over doffer and, in conjunction with the data control unit, operation of the measured length function. Rigidly mounted on the card frame, the highly efficient, rapid response pneumatic cylinder lJ CARD CLEANING SYSTEM The total suction system for the Model 2000 Card incorporates extraction from the following points within the card: • • • • • • • • Takerin / Rear blockshaft Undercard Coiler head Doffer - web area Flatstrip / Trashmaster Drafting zone Autoleveller Cylinder / Doffer pressure relief Note: Flatstrip may be collected separately. Contaminated air from each zone is fed by ducts which merge at the discharge point to a common line feeding to the central filtration plant. Direction of discharge may be upward or downward to suit either overhead or under floor main conveying ductwork. Under the card, a full width conveyor transports fallen waste to a rear extraction mouthpiece, effectively ensuring a 'dead air' zone with no adverse effect on carding performance. Rigid, smooth pipework and bends are used from each point to provide minimum air flow resistance and all ductwork and suction hoods are specially formed to avoid snagging points, from coated anti-corrosion steel sheet. A damper is incorporated in the discharge duct to facilitate balancing of the system. Located on the left hand side of the card, all cleaning ductwork is designed to be dismantled easily to provide unimpeded service access to all relevant maintenance areas. The total suction air cleaning system operates on a continuous extraction basis to achieve perfect card cleanliness and ensure environmental dust levels are controlled within all legislative standards. One important aspect of any card specification is the card clothing; from detailed research, Hollingsworth have developed a wide range of wires for each carding element. From this extensive portfolio, the most suitable clothing can be selected to ensure optimum carding performance. Combined with the experience and resources of the Hollingsworth group, individual carding features can be selected to provide the most suitable parameters for the fibre to be processed. The range of Hollingsworth features include: added advantage of reduced waste and dust emission. Dofmaster - single roll doffing arrangement capable of stripping fibre at high speed. Crush master - optional 3 roll doffer stripping system for customers who insist on crushing facilities. Pre-Carding surface - KDS1000 providing additional carding power while offering protection to the cylinder/flat clothing. Takerin Type 'B' undercasing with extension, supplied as standard with option for LCP1000 complete with carding plate and mote knife. Trashmaster - post carding attachment capable of extracting micro-dust, short fibre and fused synthetic fibre - fitted with integral carding surface. Carding by individual flats or Cardmaster, the latter require the minimum of maintenance and have the KDStOOO post carding surface - recommended in lieu of Trashmaster when processing synthetic fibres. Fabricated sheet steel cylinder and doffer with internal flanges to prevent distortion of the outer shell when rotating, and to provide a true base for the card wire. Precision ground and clothed prior to delivery, the main card elements require no further attention on initial installation. l.- Rigid fabricated main card chassis and cylinder bends provide a distortion free base on which all carding elements are mounted. This type of construction enables the card to be delivered fully assembled significantly reducing installation time.
