Key Benefits

Fabric Presentation.

Fabric presentation consists of a bridge running across the machine.  Control of the fabric is by means of an adjustable twitch rail and opening scrolls, cut with right and left hand buttress threads to remove creases and to open up the fabric for accurate pinning.  Centralised edge guiding is available as required.

Edge Control and Pinning.

Incoming fabric is presented to the machine and pressed onto pins by belts and brushes, high speed stainless steel scrolls remove any remaining curl, prior to pinning.   Pinning of fabric and final presentation is by Erhardt & Leimer equipment, consisting of photo-electric selvedge detectors, working with a proportional speed monitor, mounted on a rack and pinion.  The greater the distance the heads have to move, the faster the speed.

Edge sensing provides accurate pinning, relative to the selvedge required and fabric under process.  Fabric density and alignment is by overfeed devices, achieved by the front feed roller and each selvedge, independently controlled by overfeed wheels.   The speed is adjustable through an electronic thyristor.  Fabric input control can be further assisted by separate drives to each chain for "Bow and Skew".

Heat Setting and Cooling.

Treatment usually commences with steam, which is used to relax fibres before entering the heat chambers, each contain infra-red panels requiring an installed power of 12 k.w.   The average power consumed is only 65% of that available.  Independent controls and infra-red scanners monitor fabric being processed, checking temperature fluctuations which in turn controls heater emissions, thus achieving control of fabric temperature to plus or minus 2 degrees Centigrade.  Rapid cool-down of panels provides protection in case of machine stoppage.  Throughput speed is controlled.   Full speed can only be obtained when correct conditions have been achieved.   This "fail-safe" reduces wastage.  Cooling is achieved by blown air from four multivane fans on each side of the fabric and is adjustable to eliminate fabric distortion.  Fume extraction follows the last heat treatment and is fan-assisted.   Fabric removal is achieved by passing fabric over a roller lifting the fabric from the pins.  It can then be rolled or layered.

The drive consists of two motors, normally synchronised to give fabric speeds of 0-50 metres per minute but can vary to remove skew.  The drive system is D.C. and control electronically all the drive system, maintaining automatically any overfeed throughout the speed range, from -15% to +35%.  The chain drive is via 2 large sprockets directly driven by two 3 h.p. motors.  Chain tension is maintained pneumatically.

Control Panel - Manual.

All manual controls for overfeed edge sensing and machine speed are housed on accessible panels on either side of the machine operator bridge.  Edge sensing is Erhardt & Leimer.  The electronic temperature and DC speed controls are located in a separate ventilated control cabinet.
