Abstract
A machine includes a lower and an upper molds to support and to move two pad members toward and away from each other. A heating device includes two heating members for heating the pad members, and a sending device may send the heating members toward and away from the pad members to locate the heating members between the pad members and to allow the pad members to be heated by the heating members, and to disengage the heating members away from the pad members after the pad members have been heated by the heating members. Each of the pad members includes one or more hollow chambers for cushioning purposes.
