Abstract:
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.
