2 Self justing hin tensioner ROLL-RING is simple yet innovtive hin tensioner me from speilly formulte polymer. The unique esign is se upon simple toothe ring tht n e fitte to horizontl, vertil or igonl rives in mtter of seons, simply y pling it in-etween the two strns of hin. When the rive is in use, the ROLL-RING eforms to n elliptil shpe, ue to ompression etween the strns n ompletely sors ny slk in the system. ROLL-RING performs the jo of tensioner n mper in one, n is ielly suite to pplitions where mintenne is iffiult or impossile. TECHNICAL DETAILS BENEFITS The ROLL-RING hin tensioner provies ost effetive, time sving instlltion n mintenne. The vntges over other types of hin tensioners re: Free stning - no sprokets, olts, pltes, rilling or ostly instlltion require. The ROLL-RING is esily instlle where spe limittions prohiit the use of onventionl hin tensioners. The ROLL-RING is fitte in mtter of seons. It is rey for use without ny tools, tensioning equipment or ny further lignment or justment. It is fully effetive in vertil n igonl rives. The ROLL-RING works utomtilly, is mintenne free n self luriting. It n e use in usty n irty environments. The ROLL-RING is tensioner n mper in one, thus reuing noise levels. ROLL-RING lso works in reverse moe. ROLL-RING hin tensioners provie tensioning using: Stti tensioning fore from the elsti ring Dynmi tensioning fore from the mping of the working mteril ROLL-RING provies s muh tensioning s possile t low hin spees, n hs reserves of tensioning n mping pility for higher hin spees.

Its opertion is stonishingly simple. All funtions re integrte into single omponent. ROLL-RING utilises the hollow spe of the ssoite hin rive system giving greter flexiility to esigners n speifiers.

3 Self justing hin tensioner CASE STUDY: CHOCOLATE PRODUCTION A mjor hoolte mnufturer ws experiening serious prolems with short hin life on min proution line n lso h hin tensioning prolems, ue to the inessiility of the hin rives. Firstly, the short hin life (4-5 weeks) ws overome when the Renol Engineer reommene hnge to Renol rn, nikel plte hins, whih hs le to new hin life of twelve months so fr, n t time of going to press, the new Renol hins re still fitte. Seonly, the owntime use y the filure of the previous hins ws extene, fter the fitting of hin justers, ue to the nee for regulr justment of the hin tensioners. With time sensitive mintenne poliy, the hoolte mnufturer looke for solution to spee up the tensioning of the replement hin n ROLL-RING provie tht simple solution. The new Renol hins h to e juste to e ner their iel entres when fitte, n when the mximum ompression ws rehe the ROLL-RING ws fitte y hn within seons. No further justments hve h to e rrie out ue to the flexiility of the ROLL-RING esign n ll future hin extension will e utomtilly tken up uring the hins' life. With lrge reution in equipment owntime for tensioning justment, the hoolte mnufturer now enjoys signifint time svings, ost svings n pee of min. Sving of mintenne time for tension justments Simple instlltion Effetive mpening Unique solution THE NEW PRINCIPLE The priniple of the ROLL-RING hin tensioner is se on two simple phenomen: INSTALLATION AND MAINTENANCE ROLL-RING hin tensioners re mintenne free n n e fitte to wie vriety of hin rives with no instlltion own time. The requirement is tht: There is working spe with gp etween the hin strns whih is smller thn the imeter of the hin tensioner. There is suffiient gp etween the hin rive sprokets. We reommen tht the hin tensioner is positione etween two hin strns suh tht there is t lest one hin pith etween the ROLL-RING n the smllest sproket. The ROLL-RING n lso e positione just s effetively outsie this reommene re, s long s it is suffiiently prestresse. In this se, prtil tril n error is reommene. ROLL-RING hin tensioners n e use in line within the sme hin strn, or prllel with eh other in multi-strn hin rives. Plese note tht triplex hin rives only require two ROLL-RINGS positione on the outer strns.
