    Weld on Strip Lagging is available from CCI's stock and is easily installed on drum pulleys either in our facilities or in the field. We stock 72" long strips with retainers in diameters from 10" to 48". Not only do we have standard 60 durometer SBR available, but we can provide special compounds like; 40 durometer rubber, MSHA, EPDM and SOF (Static Conductive Oil & Fire resistant).

    A unique and proven method of increasing conveyor and elevator performance. Designed for direct application to the drive pulley, this product can transform any belt system into a high-performance, low-maintenance operation. In addition to providing outstanding increases in the coefficient of friction (traction) between the belt and pulley, it serves to protect the pulley face and belt cover from damage and provides a self-cleaning action to prevent material build-up on the pulley.

    A combination of elastomer compounds and product design features is consistently superior to conventional vulcanized, cold bond or bolted-on pulley laggings. Unique factory bonding system eliminates lagging separation thus making Weld on Strip Lagging ideal for severe service conditions with dual or high horsepower drives or using steel cable conveyor belts.

Meets OSHA standards for grain and fertilizer handling.

 

Proper installation will provide the full service life and performance that make Weld on Strip Lagging products an exceptional investment.

  Weld on Strip Lagging provides specially compounded elastomer padding vulcanized under high pressure to heavy-gauge steel plates which are shaped to conform to each pulley face. The plates slide in and out of special retainers which have been securely welded or bolted to the pulley face.

  1. Exclusive elastomer compounding provides a lagging pad with exceptional drive-pulley traction, abuse resistance, and extra long service life. The elastomer retains its integrity under the most severe operating conditions.
  3. 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 life.
  2. Factory hot-vulcanization under 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 lagging.
  4. Rust-resistant metal retainers are permanently welded or bolted to the pulley face to securely hold the lagging pads in place. When properly installed, lagging cannot shift or pull free from the effects of impact, trapped material, or belt or product
movement.

How To Order

PRE-INSTALLED ON NEW PULLEYS
Conveyor and elevator pulleys can be readily obtained with Weld on Strip Lagging pre-installed. Simply specify Weld on Strip Lagging when ordering. Or the pulley may be purchased separately and Weld on Strip Lagging installed on site.

FOR ON-SITE INSTALLATION ON NEW OR USED PULLEYS
Determine which method of application is to be used:
A.) “Butt seam” method using 72" pads which makes maximum use of all material; however, pieces 4" or shorter should be discarded. The number of 72" pads required for butt seam application for most common pulley diameters can be obtained from Table 1 below. However, Weld on Strip Lagging can be factory formed to any diameter and installation accomplished using published installation procedures. For pulley face widths not shown, use the next larger width, or use the formula to calculate requirements.
B.) “Full width” method with pads cut to exact pulley face width, no butt seams.

NOTE: This table utilizes all lengths over 4 inches long by butting them end-to-end in a random pattern.

FIGURE 1 Formula for selecting the number of 72" pads required for any pulley diameter and face width (butt seam application).

Butt Seam Method

Instead of using the table, the number of 72" pads required for any pulley may be calculated using the following simple procedure

Example: 36" diameter x 38" face pulley
1. Divide the pulley diameter by 2 to determine the number of rows of pads needed to go around the pulley.
1.
36" diameter/2 = 18
 rows of pads
2. Multiply the number of rows of pads by the pulley face width.
2.
18 x 38" = 684"
  
3. Divide by 72" to determine the quantity of full-length pads needed. Round up to the next full length.
3.
684"/72"
 = 9.5 or 10
full length pads required.

Full Width Method

When no butt seams are desired, the number of 72" pads required will depend entirely on the pulley and the quantity of face-width pad lengths which can be cut from one 72" pad. In the example shown at left, 18 pads would be needed.
