Abstract
Abstract An improved padding press adapted for convenient and relatively rapid padding of continuously variable sizes of paper, is disclosed. The padding press includes a base which incorporates a blower assembly for forced movement of heated air. A support board assembly, including a main support board, is slideably positioned on a top surface of the base and is adapted to occupy at least one predetermined fixed position thereon. An adjusting board is removably attachable to the base into a position wherein the adjusting board is substantially perpendicular to the main support board. The adjusting board has a pair of adjustably mounted guide rails adapted for receiving continuously variable sizes of paper. A clamping board is attachable to the support board assembly through a pair of cords and a clamping bracket assembly. Each cord is attached to the support board assembly through a rotatable and lockable spindle so that the tension of the cord is adjustable. The clamping bracket assembly is adapted to require a small physical force on the part of the operator to be locked into a clamping position wherein the clamping board applies a clamping pressure on a stack of paper positioned between the clamping board and the main support board. The support board assembly is adapted to be slid out of its predetermined fixed position to expose a glued edge of the stack of paper to heated air blown by the blower assembly.
