2 HISTORY Webster For over 00 years, Webster Industries, Inc., has provided conveying solutions to a diverse range of markets with our extensive variety of products and industry expertise. Towner K. Webster founded Webster in 876 in Chicago, Illinois, with his Common Sense elevator bucket. In 907, Webster relocated to Tiffin, Ohio, where our corporate headquarters is located today. Throughout the past century, Webster has evolved from producing elevator buckets to being the world s leading manufacturer of engineered class chains, commercial castings and vibrating conveyors. Webster s reputation for high-quality products is rooted in a tradition of manufacturing excellence that is based on American materials, American labor and American pride. LOCATIONS Our Tiffin headquarters has more than 0,000 square feet of manufacturing space, including a malleable iron foundry, punch press operations, heat-treat facility, machine shop, fabrication department, chain assembly area, an in-plant laboratory and testing facilities. Our two warehousing and assembly locations, located in Meridian, Mississippi, and Portland, Oregon, allow for quick access to over $7 million of inventory, and our three manufacturing facilities stock over 250,000 feet of chain to quickly meet our customers needs. VERTICAL INTEGRATION While many companies are relying increasingly on outsourcing for production needs, Webster Industries has invested in building, maintaining and growing a vertically integrated manufacturing system. With full services under one roof at our Tiffin, Ohio, headquarters, Webster offers superior product design, consistent product quality, and the best delivery time in the industry.

In hole other sizing, words, used we in use manufacturing the highest the quality pitch solution holes of which our drives chains, value are two to our of customers. those processes. Two such processes are utilized in manufacturing the pitch holes of our chains. One is burnishing and the other is perfect hole sizing. Burnishing is a unique cold-forming process where a graduated mandrel Burnishing is a unique cold forming process used by Webster where a graduated (punch) is used to punch the sidebar pitch holes. First, the punch pierces the mandrel (punch) is used to punch the sidebar pitch holes. First the punch pierces sidebar material, producing a heavy tapered slug. The punch rubs the metal the sidebar material producing a heavy tapered slug, (Fig. ). The mandrel rubs surface of the pitch hole with sufficient force to cause plastic flowing of the the metal surface of the pitch hole with sufficient force to cause plastic flowing of metal. This rubbing or smearing (burnishing) action of the metal fills the breakout or tapered portion of the hole that was produced during the initial piercing the metal.

4 Welded Steel Mill s Welded steel mill chains are designed for rugged, abrasive and demanding environments. The design allows for operating conditions that are less than desirable. Their rugged welded construction permits high speeds, minimal lubrication and easy modification for application specific attachments. MATERIAL Sidebars and barrels are medium carbon steel. Pins are medium carbon alloy steel and are thru hardened for maximum chain life. Pins can be induction hardened for even more wear resistance. The WH chains also have thru hardened sidebars and barrels for greater strength and wear resistance. All parts can be furnished with additional heat treatment on request or as the operating environment requires. ASSEMBLY Welded steel mill chains are riveted construction with cottered connecting pins. Cottered construction is available on request. INTERCHANGEABILITY Welded steel mill chains are interchangeable with other standard makes of corresponding sizes and numbers. APPLICATION Welded steel mill chains are used in wood yards, paper mills, OSB plants, grain systems and ethanol processing. They provide long life with very low maintenance. OPERATION Maximum chain speed depends upon size of sprockets. For Conveyor Service see Table 2, Section A. General Dimensions No. Style Average Pitch Inches Approx.

Light Rugged Thin Wall Solid Weld RIGID TWO-PIECE WELDED CONSTRUCTION The Webster barrel wraps around the pin, which reduces flexing. This minimizes fatigue failures and increases pin life. Stress Stress Load Bearing Construction IMPACT RESISTANCE The structure of the Webster two-piece welded barrel can take more vertical load impact without weakening the barrel or causing barrel deformation, which in turn eliminates binding between the barrel and the pin

26 Vibrating Conveyors WEBSTER CONVEYORS Webster vibrating conveyors have been the leader in servicing sawmills and other forest product applications for over 40 years. Our conveyors are utilized extensively to effectively convey bark, chips, edgings, sawdust, slabs and trim blocks. Webster conveyors are designed to provide spill- and jam-free operation of the long and irregularly shaped sizes of waste common to the forest products industry. The smooth, continuous trough of our conveyors handles this waste with minimal operational maintenance, providing years of reliable service. In addition, Webster conveyors can be fitted with screens to remove small particles from the waste stream; fiberglass or stainless steel section to allow for metal detection or removal; oversize pans, which are designed to catch or turn materials effectively; and transition chutes and spouts to seamlessly feed waste into other conveyors, chippers or hogs. Webster s vibrating conveyors are available in two models, flat spring and coil spring, and both are effective solutions for the tough demands of the forest products industry. FS SERIES VIBRATING CONVEYORS FS series conveyors are a cost-effective solution to many conveying applications. FS series conveyors are available in three models, FSL, FSM, and FSH, and all designs incorporate standardized sectional construction. FS conveyors utilize a plastic composite flat spring, which acts both as the spring and a guide arm in the conveyor. These heavy duty flat springs are glass-filament reinforced, which allows for continuous, maintenance-free conveyor operation. In addition, Webster conveyors utilize a positive connected eccentric drive, making them simple, yet rugged, conveyors. Webster models FSL and FSM are designed for light- to medium-duty applications when lower-capacity, smaller-size material handling is required. Usual applications include sawdust, chips and trim blocks. The FSH model is a more robust design, and is capable of handling larger volumes and material sizes. FSH conveyors are often used in handling edgings and slabs, as well as collecting material from other conveyors. The FSH model is also used for screening and metal detection before material is fed into a chipper. FS series conveyors are designed for simple, efficient field assembly. Each model is designed and manufactured in preassembled sections with jig fixtures. The pans come with bolt flanges between sections to allow for more efficient installation and replacement. The drive sections have been assembled with a timed and tested positive eccentric drive (P000 FSL, P5000 FSM, and P8000N/P8000W FSH). FS series conveyors feature fabricated steel pans (standard) and a natural frequency spring system tuned to the conveyor requirements. In addition, Webster can produce custom pan sizes, as needed, to suit any application. 26

27 Vibrating Conveyors COILWEB SERIES VIBRATING CONVEYORS Webster CoilWeb vibrating conveyors are heavy duty systems that are configured with a broad range of capabilities for the most demanding applications. The CoilWeb and CoilWeb -LS models are configured with coil reactor springs with rocker arms and a coil-spring drive, tested and tuned for the application. The CoilWeb series utilizes the natural frequency principle to efficiently move waste material and minimize power requirements. CoilWeb conveyors come configured as the standard unbalanced design, balanced, or a combination of balanced and isolated for vibration-sensitive locations. The CoilWeb series features the use of a coil spring drive connected to the pan. The incorporation of the drive spring substantially lowers the starting and full-load torque requirements in the conveyor. This results in a dramatic horsepower reduction over a positive connected drive. In addition, the coil spring drive allows for much longer conveyor lengths on a single drive. CoilWeb conveyors are offered with standard pan sizes and capacities. However, Webster has the capability to build custom sizes to suit each application
