Zero Tangent Modular Belt Curve

Pack Air recognizes that often equipment placement and space restrictions do not allow for a conveyor with a side flexing table top or modular chain, because of the tangent (straight running) sections that are required before and after the curves. These tangents are required in order to properly drive the chain and allow it to “relax” for proper tracking before the chain enters the return carry way. Unfortunately, these tangent sections add to the overall conveyor length and can dramatically limit your floor space.

In these types of applications Fabric Belt Curves have historically been one of the only options available. The disadvantage with Fabric Belt Curves are their inherent design issues. Such as oily drive chains on the edge of the belts that make it difficult to keep the belts clean, point loading at belt grommets that can cause tears in the belt, or other styles that rely on pinching the belt between friction rollers that can cut through the belt if the tension is not properly adjusted.

When maintenance is required on Fabric Belt Curves, it can be very difficult and time consuming to replace the belts. So much so, that some end users have purchased an entire backup conveyor because it was quicker to replace the entire unit than it was to try and replace the belt on the line. They would then replace the belt during off-line maintenance to have that conveyor ready as the next backup.

We realized that the use of the Fabric Belt Curves was an ongoing problem and it was time to come up with an innovative solution, so we worked with one of our modular plastic chain suppliers to develop a chain that would offer an alternative solution to this problem.

Zero Tangent Modular Belt Curves have fewer moving parts and offer a simple plastic modular belt construction which makes for a cleaner design that is more maintenance friendly than fabric belts. The plastic modular belts will only follow the specific radiused path that the chain was manufactured for and it can be made in 30, 45, 90, 180 degree, or special degree of angle sections to fit your specific application. The belt is available in a variety of widths and radii for use in a wide range of product handling needs.

Applications include mild steel frame construction for paper, poly wrapped bundles, cases and other dry goods, and stainless steel construction suitable for wet or corrosive environments, bakery or direct food contact.
