A method and system for softening a high-density leather finished roll good and other stiff high density roll goods may include adjusting a first horizontal distance between a first impact grid and a first tunnel opening and adjusting a second horizontal distance between a second impact grid and a second tunnel opening based on the stiffness of the roll good. The method also may include introducing the roll good in a first direction through the air tunnel until the roll good hits the second impact grid, and introducing the roll good in an opposite direction through the air tunnel until the roll good hits the first impact grid. The method may further include passing the roll good through a cooling chamber.

FINISH CURING METHOD AND SYSTEM FOR LEATHER-BASED SUBSTRATES
A method and system for finish curing a leather-based substrate includes applying a base coat onto a surface of a substrate to form a coated substrate and passing the coated substrate through a first heating zone to heat the base coat. The method also includes passing the coated substrate through a second heating zone that emits infrared electromagnetic waves at a frequency corresponding to strong absorption by water to remove a desired amount of moisture from the base coat, and passing the coated substrate through a third heating zone to completely cure the base coat on the coated substrate.
F26B 3/30 - Drying solid materials or objects by processes involving the application of heat by radiation, e.g. from the sun from infrared-emitting elements
