Abstract
A device and method for extending the useful life of a carrying fabric in a dryer by maintaining the edges of the fabric at a temperature below that at which thermal degradation occurs. This is achieved by applying a cooling liquid to the edges of the carrying fabric so that thermal energy can be transferred from the fabric to the liquid and thus maintain the edges of the fabric at moderate temperatures.
Claims18
A device for extending the useful life of a carrying fabric in a dryer by maintaining the edges of said carrying fabric at a temperature that minimizes significant thermal degradation, said device comprising application means for applying a cooling liquid to said edges of said carrying fabric, said application means comprising at least one nozzle positioned along each edge of said carrying fabric proximate to said dryer such that said nozzle sprays said cooling liquid on to said edge of said fabric.
A method for extending the useful life of a carrying fabric in a dryer by maintaining the edges of said carrying fabric at a temperature that minimizes significant thermal degradation, said method comprising applying a cooling liquid to said edges of said carrying fabric, said cooling liquid being applied by a nozzle along each edge of said carrying fabric proximate to said dryer such that said nozzles prays said cooling liquid onto said edge of said fabric.
