ABSTRACT:
A process of making a laminate and laminate formed thereby and a process of making an abrasive laminate and laminate formed thereby include providing a first moving sheet having a first side and a second side, applying active foaming material in a pre-mixed form to the first side, providing a second moving sheet having a first side and second side, the second sheet provided in a manner such that the first side of the second sheet contacts the foaming material to form an uncured laminate and maintaining the first sheet and the second sheet at a predetermined distance relative to one another during a curing period of the foaming material such that the foaming material bonds to the first sheet and the second sheet and upon curing forms a laminate.
