Designed for direct application to thedrive pulley, this product can transform any beltsystem into a high-performance, low-maintenanceoperation. In addition to providing outstandingincreases in the coefficient of friction (traction)between the belt and pulley, it serves to protect thepulley face and belt cover from damage and providesa self-cleaning action to prevent material build-up onthe s combination of elastomer compoundsand product design features is consistently superiorto conventional vulcanized, cold bond or bolted-onpulley laggings.

2 Unique factory bonding systemeliminates lagging separation thus making Slide-Lag ideal for severe service conditions with dual or highhorsepower drives or using steel cable conveyor MSHA approved SOF compound provides anadded margin of safety for potentially hazardousoperations in underground mining and meets OSHA standards for grain and fertilizer industry operations require the superior performancefeatures provided by Slide-Lag . Slide-Lag provides cost savings underground where space and time requirements are always 2 The Slide-Lag specially compounded elastomer padding vulcanized under high pressure to heavy-gaugesteel plates which are shaped to conform to each pulley face. The plates slide in and out of specialretainers which have been securely welded or bolted to the pulley four special features make Slide-Lag products the most unique and reliable system for lagging all conveyor and elevatorpulleys.

3 Slide-Lag can be installed on the job, usually without removing either the belt or pulleys from the system. Eventualreplacement of worn or damaged pads is even quicker and easier, since the retainers are already in Economy of Readily Available Slide-Lag Slide-Lag is inventoried in standard factory producedlengths by authorized HOLZ stocking offers system owners new economies byeliminating the need for in-plant stocks of laggingand/or extra lagged pulleys. Owners may alsoeconomize by installing the lagging themselves, usingeither of the following methods of application:1.) The "butt seam" method, which utilizes all material cut from full pad lengths. The ends of each cut piece are butted together. Butt seam application is usually the most economical approach to use. 2.) The "full width" method, in which each pad row is provided with full face width pads that have no butt seams (except on pulleys over 72" wide, where a butt seam is used at the pulley center line).

4 Absence of butt seams is attractive, but offers no performance advantage over the less costly butt seam application instructions are available for eithermethod.

Exclusive elastomer compoundingprovides a lagging pad with exceptional drive-pulley traction, abuse resistance, and extra long service life. The elastomer retains its integrity under the most severeoperating Factory hot-vulcanizationunder pressure assures the best possible bond of Rubber to backing plate. No lagging failures from loss of adhesion and separation the most common problems associated with conventional Steel backing plates are precision formed at the factory to fit the curved surface provided by each individual pulley diameter. Insures proper pad stability and long Rust-resistant metal retainersare permanently welded or bolted to the pulley face to securely holdthe lagging pads in place.

5 When properly installed, lagging cannot shift or pull free from the effects of impact, trapped material, or belt or product movement. SUPERIOR TRACTIONS lide-Lag 's Rubber compounding and tread-likesurface which combines double chevron grooves andshallow slits on individual pads promote belt driveand maximum traction. Slide-Lag has provensuperior to all other lagging methods in a wide varietyof applications throughout the world. This isparticularly true where drive-pulley slippage has beena problem. LONGER LIFEThe retainers which form an integral part of theHOLZ Slide-Lag installation method provide astrong, virtually unbreakable bond between thelagging and pulley face. This exclusive featureeliminates costly lagging failures from separation andloss of adhesion, and insures years of trouble-freeperformance. Pads are locked in place to preventlateral movement using simple procedures outlined inSlide-Lag installation instructions.

6 ABUSE RESISTANCES lide-Lag is fabricated from top quality, abrasion-resistant elastomers to a maximum practical thicknesscapable of withstanding the most severe operatingconditions. Consequently, failures from Rubber tearingor gouging are dramatically reduced, andmaintenance costs are kept at a minimum. EASY INSTALLATIONS lide-Lag can normally be installed without removingthe pulleys from operating position or opening thebelt splice. Simply release belt tension to allow pulleyrotation, attach retainers, slide and lock pads inplace, tighten belt and resume operation. Slide-Lag will effectively replace other types of lagging using theKeep costly pulleys out of the graveyard specify HOLZ Slide-Lag . Slide-Lag minimizes downtimeSLIDE-LAG lowers maintenance costsPage 4same clean-up procedures that are always required toremove other types of old lagging. However, onceSlide-Lag is installed, future clean-up problems forlagging replacement are eliminated.

7 When orderingnew equipment, specify Slide-Lag replaceable laggingfor pre-installation prior to delivery. QUICK REPLACEMENTR eplacing Slide-Lag is even more convenient andeasier to do, since the retainers are already inposition. High costs generated by pulley removal forshipment to a Rubber fabricator just to have laggingreplaced are permanently erased. If scheduledmaintenance time is limited, pads can be replaced afew at a time during the brief shutdowns that alwaysoccur during day-to-day operation. SELF-CLEANINGS lide-Lag 's unique combination of double chevrongrooves, shallow slits and individual pads results in a kneading or flexing action that actively resists material build-up. Foreign material works its way tothe edges of the pulley through the channels betweenthe pads where it falls away. This continuous, built-in,self-cleaning action keeps matieral build-up problemsdown, and associated belt tracking troubles virtually instructions in Holz Bulletin PL 105 makeinstallation quick and Slide-Lag EDGE-CROWN to create a crown on a flat-face drive pulleyStandard conveyor engineering usually calls for acrowned surface on all drive pulleys.

Eliminating erratic lateral belt movement isimportant in preventing damage to the belt caused bycontact with the Edge-Crown transforms a flat-face pulley intoa crowned configuration. Edge-Crown laggingcreates a barrel-shaped crown that eliminates the highbelt stress, scrubbing, and resultant wear associatedwith center crowned pulley designs.
