Abstract:
1. A caul for applying pressure in laminating, the caul comprising: a base portion of the caul positioned between a first corner portion of the caul and a second corner portion of the caul, wherein the base portion is configured to have a curved shape when the base portion is in a relaxed state but moves downwardly to a flatter shape when the base portion is subjected to an external pressure during lamination, and wherein the downward movement of the base portion to the flatter shape causes the first corner portion to move outwardly relative to the base portion and also causes the second corner portion to move outwardly relative to the base portion in a direction opposed to a moving direction of the first corner portion wherein the caul is configured to compact laminating materials into a first female corner portion and a second female corner portion of a corresponding female mold surface.
