ABSTRACT:
The invention comprises a method for manufacturing a laminated pad in a cost-efficient manner. In one embodiment, the method comprises the steps of applying strips of adhesive to a first substrate and mounting the first substrate to a second substrate. Next, adhesive is applied to the entire width of a third substrate which is in turn mounted to the laminated first and second substrates to create a laminated sheet. The laminated sheet can be slit and then die cut into individual laminated pads. The pads which result from this process have a base pad, an intermediate layer which is adhered to the base pad and a top layer in which only a portion of the top layer is mounted to the intermediate layer.
