There’s hardly a wire and cable manufacturer without a turn-around capstan being used in their facility. Using an outer wrap belt to apply tension on the cable and inner capstan “liner” belt to protect the cable from the metal capstan sheave, it’s an integral part of the wire and cable production process.
For years, there has been one offered solution for the inner capstan liner belt. A spliced “rubber band” that can be stretched onto the capstan sheave. These belts are time-tested but offer no mechanical advantages and can sometimes be trouble points in the wire manufacturing process. Rainbow Rubber & Plastics, Inc. has developed a truly endless liner belt made of elastic urethane that offers greater wear and abrasion resistance. Removing the splice area also removes the risk of failure of the splice. Working closely with manufacturing partners, we were able to generate a 60% reduction in the consumption of capstan belting for their process across all machines.
What are Polyurethane Liners
Urethane liners are an elastic-based component used to protect the belt from the metal sheave. Urethane liners differ from other commonly used liners due to their higher abrasion resistance and significant elastic memory. This makes them a perfect solution for load conveyance and power transmission applications.
In the past, a spliced “rubber band” was the go-to solution for belt-based equipment within the wire and cable industry. This offered no mechanical advantages and was known to create points of contention during the wire manufacturing process.
Advantages of Polyurethane Liners
Unlike solutions of the past, urethane belts and liners yield prominent advantages for the wire and cable industry. The key benefits of urethane liners include the following:
Abrasion Resistance
One of the key advantages of urethane liners and urethane belts is their abrasion resistance. Urethane liners are durable and are less prone to developing grooving and cutting during their use. This heightened amount of resistance makes the belt or lining last much longer than other solutions.
Easy to Install
When it comes to urethane, installation is easy. This unique elasticity allows for easy replacement and the creation of different shapes—all due to its thermoplastic makeup.
The combination of its ease of installation and other advantages make the use of urethane belting and liners a beneficial investment for a variety of facilities within the wire and cable industry.
