The system comprises a hopper attached below a table for holding two stacks of the slide mounts. A pick-off station removes the slide mounts from the slide mount stack. The slide mount is moved to a slide mounting station and then sealed underneath a ultrasonic welding head. The hopper includes a carousel that rotates either stack into a predetermined position underneath the pick-off station. The motorized hopper used in conjunction with the pick-off mechanism and hold-down apparatus eliminate the previous problems associated with slide mount jamming. The ultrasonic welding head vibrates the top half of the slide mount creating a friction between the internal faces of the top and bottom halves of the slide mount. This friction heats adhesive inside the slide mount sealing the top and bottom halves of the slide mount together. The ultrasonic welding head allows slide mounts to be sealed without using a high temperature heat source keeping photographic slides from being destroyed in the event that the slide mount becomes jammed during the sealing process.
