    摘要: The present invention is directed to a system for thermoforming a batch of dental appliances simultaneously. An embodiment of the invention includes a vacuum plate having an upper surface and a plurality of cups for receiving dental models. A polymer sheet extends over the upper surface of the vacuum plate and over the cups. A heater cap that is movable in proximity to the cups is provided to heat the polymer sheet to be formed onto the dental models. The vacuum plate is configured to create a vacuum seal between an upper edge of the cups and the polymer sheet. A vacuum source is provided to apply a vacuum to the cups below the polymer sheet wherein the pressure contained in said cups is lower than atmospheric pressure whereby at least a portion of the polymer sheet is drawn into each of the cups and drawn over the dental models to form an aligner over each of the dental models. The invention includes the process of drawing a vacuum in a series of steps, or phases, to the cups below the polymer sheet to form the polymer effectively around the dental model.

    摘要: A thermoforming machine is provided having a load shaft end adjustment apparatus. The thermoforming machine load shaft end adjustment apparatus includes a load shaft, a backlash nut, a height adjustment nut, a collar, and at least one fastener. The load shaft has a threaded end segment and an axially extending key slot. The backlash nut is threaded onto the end segment. The height adjustment nut is threaded onto the end segment adjacent the backlash nut. The collar is configured to receive the height adjustment nut for rotation, having a key configured to be received within the key slot, and is configured to be mounted onto a platen of the thermoforming machine. At least one fastener extends between the backlash nut and the collar and is configured to secure together the backlash nut and collar with the height adjustment nut interposed there between. A method is also provided.

    摘要: An apparatus, system and method for dovetail locking mechanisms are described herein. A system for locking the dovetail of a trailer in the travel position includes a sled for locking the dovetail of a trailer in the travel position, a railing on the underside of the trailer to accommodate the sled, wherein the sled is moveably attached to the railing such that the sled can slide into a loading position clear of the dovetail or a travel position at least partially beneath the dovetail, and means for actuating the sled to the loading position and travel position. A method for locking the dovetail of a trailer includes moving the dovetail of a trailer into the travel position and sliding a sled from a loading position underneath the trailer to a travel position at least partially underneath the dovetail of the trailer.
