The critical stacker belts on corrugators are large, expensive, and not easy to work with. A typical installation of a stacker belt will last several years, and great care is taken into consideration when Sparks Mol builds these belts.
Our segmented urethane v-guide has been battle-tested in some of the harshest and most demanding manufacturing environments imaginable. Several industries agree that this special v-guide is a savings generator. Our cast urethane process prevents the guide from peeling up prematurely from the back of a belt and leading to tracking issues. Belts that are unable to be tracked often fold over on themselves on corrugators, create jam-ups, and then ultimately will need to be replaced.
Unfortunately, the industry standard is a Thermoweld PVC welded guide that separates in a complete strip. This mode of failure does not allow the belt to maintain its orientation inside the groove of the slider bed or pulleys. We work with a wide range of corrugated and converting plants that rely on Sparks Mol to eliminate downtime with stacker belt failure.
On a recent encounter with a customer, we were advised that the replacement belt purchased elsewhere failed within a week as the v-guide delaminated from the Slip Top belt. Our cost to the customer with the upgraded v-guide was $1,800 less expensive out of the gate. The increased belt life has saved tens of thousands of dollars of downtime.
