‘Tabs’ derives from the term tableaucurtains, curtains which were often drawn back and up to reveal a scene,and dates as far back as the 1880s.Audiences over the decades have cometo expect to be greeted by the glow ofthe tab warmers - lights gentlyilluminating the plush rich red velvetcurtains adorning a proscenium arch, in anticipation of the evening’sentertainment. Indeed, most venues willhave a curtain to mask the stage when a performance is not in progress, butthere are many other requirements andfunctions for today’s theatrical curtain.

A curtain can be used to enhance dramaand spectacle, or perhaps its primaryfunction might be for fire safety. Somedrapes are required in a venue to define a physical boundary, for example using a curved track to circumnavigate a spaceto form a perimeter, common in drama ordance studios. Perhaps a curtain mightserve to reduce echo and reverb,improving the audio experience, or maybeit offers a blackout solution. But for somany venues, the requirement for itscurtain and subsequently its track system,is multi-functional - a workhorse systemfulfilling many roles.

The requirements of a track system will initself define which particular model orsolution will best suit the application.Primary considerations are the size and theweight of the curtain: it might not even becurtain that is required to track, but rather

a set-piece or video screen. Size andweight will instantly rule out, or rule in,particular track systems.

accommodate heavy straight curtains ofalmost any length. In its medium-dutyrange is Besteel, suitable for medium orlight-weight straight curtains. Both canbe suspended or ceiling-mounted, orsupplied with a pipe-backbone.

For architectural solutions Models 113Specifine and 220 Trak-Eze are intendedfor straight curtains and have theadvantage of being recessed, surface-mounted, or suspended, with the cordwithin the track. These systems are lowprofile tracks but also offer high loadcapabilities.

If you need to bend it like Beckham, thenthe versatility of the Model 140 Rig-I-Flexand Model 132 Flex-I-trac series allowsfor both curved and straight systems.These tracks can be easily curved in thefield or can be supplied factory curved tocustomer specification. These can becord operated up to 18m in length andwalk-along operated to almost anylength.

The Model 500 Patriarc is one of ADC’sheavy duty curtain track system butdespite its size, it is one of the quietestand easiest operating tracks in the ADCrange.

ADC offers multiple-stop, low voltage andvariable speed control options for all theirmachines right up to colour touch screenoperator interfaces. ADC’s LS-1 and LS-2LogiStop multiple-stop controllers canprovide up to 20 easily programmablepositions. The Model LS-1 is DMXableand the preset stops can be easilyassigned to the lighting desk.www.automaticdevices.com

Studio Rail is an extruded aluminium walkalong rail that has beendesigned mainly as an overhead studio rail system but is equallysuitable for curtains. “The great thing with this system is that wemanufacture a wide range of friction braked carriages that are perfectfor carrying lights, screens or even scenery, so it is extremelyversatile,” says Laurence Dyer of Doughty UK. Available in two sizesand finishes, natural aluminium or black anodised. www.doughty-engineering.co.uk

GerrietsGerriets is known for its stage machinery products as well as fabricsand soft goods for theatres and opera houses around the world. Itsmetal workshop in Umkirch, Germany, features CNC millingmachines and other metal fabrication facilities, and the companyworks closely with engineers and project managers to custom-buildtrack systems, and modify Gerriets products, to meet specificrequirements.

Gerriets’ track systems cover a variety of applications, from theTRUMPF walk-along track for loads of 60kg, through to CARGO XL,which is capable of carrying loads of up to 1200kg.

Another product of note is Gerriets’ STRATUS Festoon system, a vertically motorised curtain system which can work with a range offabrics. This system was recently installed at the Fondation LouisVuitton, a cultural centre in Paris designed by architect Frank Gehryto resemble a glass cloud. The building’s form is provided by 12curving glass-paneled sails, with a complex 15m x 14m Gerriets’track designed to follow the contour of the façade.

sOver 1.5km of Gerriets’ FENCE ScissorTracks have been installed in the last decadein venues across the world, including theBolshoi in Moscow. FENCE tracks allow forthe designed fullness of a curtain to bemaintained during both its opening andclosing.

New to Gerriets’ range is its CUE-TRACK 2system which works on a continuous chainto ensure accurate positioning at fixed orvariable speeds. CUE-TRACK 2 is often usedfor main curtains with a tight stacking area,and in blackout and room dividing systems.It is very compact in size and can bemounted horizontally, vertically or in angularpositions. www.gerriets.com

Hall StageEstablished in 1898 by George Hall, HallStage makes steel curtain tracking systemsfor any application, and for any material.Having originally started as a chandlerysupplier for canal boats and transport ships’rigging, Hall may have been well known toearly stage crews, who were often recruitedfrom among mariners for their knowledge ofrope-work and rigging.

Today, as well as track fabrication, thecompany offers bespoke design services,installation, maintenance and certification ofgeneral stage engineering systems.

The track pictured in Hall stage’s 1920scatalogue is the predecessor to the modernday T70. T70 falls in the heavy duty end ofthe range, and is aimed at large venues orsystems where heavy or long curtains arerequired. Current projects include filmproductions underway at Pinewood andShepperton Studios. Market demand in the1950s led to the lighter Anglia track, today’sT60 system, which can be manufactured tomeet any configuration.

Estimates suggest that over 1000 miles ofT60 and T70 track has been manufacturedand installed over the past 50 years, and thecompany continues to maintain systems builtin the 1930s and still in use today.

Recent developments include the newChaindrive system which motorises heavydrapes, scenery and screens, and a currentproject sees a T70 Chaindrive installed tomove a 500kg LED screen.

sinstallation has always been a key priority;today Stage-Track offers a range of products.

The clue’s in the name - Easy Track is aimedtowards schools, colleges and Village Hallsas well as TV studios. The maximum tracklength is 25m in motorised systems, but canbe longer when made-to-order, or as walk-along; 10kg or 20kg runners are available.Easy Track Lite is a lighter version of EasyTrack but uses the same components and issuitable for light-duty back-drops, andapplications.

Other tracks include the ST-A, ST-B, and ST-Cranges. ST-A is aimed at small and domesticapplications with a maximum track length of10m when motorised, longer in walk-along.ST-B is targeted for general stage use andcyclorama applications. It has a maximumtrack length of 24m when motorised andagain longer as a walkalong. Similar to ST-Bbut with reinforced sections, ST-C is used forheavy loads. It has a maximum track lengthof 24m when motorised.www.stagetrack.co.uk

Triple ECelebrating its 30th anniversary this year,Triple E entered the market in 1984, winningthe ABTT Theatre Show’s Product of the YearAward for its Loose Pin Hinge - and it hasgone on to win three more ABTT awards inthe years since.

Triple E’s I-beam track systems, Unitrack andUnibeam, were introduced in 1988. TodayTriple E manufactures eight ranges: Unitrack,Unibeam, Chainbeam, Chaintrack, Erail,Unicyc, 3Way and 2Way, with an ethos ofsimple design, rugged construction andease of installation. And it’s a case of horsesfor courses - each range offers advantagesin particular circumstances, such as simplewalk-along systems for space dividing, ormotorised systems used for example to varyvenue acoustics.

Unitrack has a simple one bolt and fourspigot joining system which along with ball

raced runners and nylon pulley, offerssmooth and silent operation. Most solutionscan be serviced with standard parts butsystems can also be custom designed. Theaddition of a TDrive motor allows for a fullymotorised system.

Unibeam is an aluminium extruded blackanodised track system and shares manycomponents of Unitrack. Stock length is6.1m, and it can be curved to a minimumradius of 2m. The symmetrical design allowsfor Unibeam to be rigged either way up.

Erail is a compact aluminium track suitablefor medium- to heavy-weight curtains: it canbe operated manually or by motors.

New in the Triple E stable is its range oftrack-mounted plug-and-play motors, theTDrive and the SDrive, which can be used onboth straight and curved systems. TheTDrive is primarily intended for Unitrack andUnibeam and the SDrive is designed forErail.

This year, Triple E launched its new DMAXcontrol box which allows all of its motors tobe controlled via DMX.

Of course, in addition to its ‘standard’ range,Triple E also undertakes many customdesign engineering projects. www.3-eee.com
