Abstract: A molten thermoplastic circulation system that is used in conjunction with thermoplastic melter kettles. The molten circulation system includes a vertical material transfer tube that is coupled to a melter kettle and includes an auger. The vertical material transfer tube is coupled to the top and bottom of a melter kettle so as to transfer molten thermoplastic between the bottom and top of the melter kettle. The vertical material transfer tube is at least partially surrounded by a heat chamber through which a heated fluid such as hot combustion gases or heated oil can flow. In use molten thermoplastic material that is heated at a higher temperature at the bottom of a melter kettle near the combustion chamber is transferred through the vertical material transfer tube to the top of the melter kettle to improve melting efficiency.

Abstract: A temporary tape removal apparatus that includes: a chassis having fixed and guiding wheels; a boom arm extending outward from the chassis and being movable between up and down and side to side positions; a spool assembly including a rotatable spool for winding used temporary tape thereon mounted on the boom arm; and controllable drive means to rotate the rotatable spool. Using the apparatus to remove lane marking tape from pavements involves moving the temporary tape removal apparatus along a pavement having a length of lane marking tape thereon, and pulling the lane marking tape off the pavement by winding the tape onto the spool. Single lines of tape can be removed and multiple lines of tape can simultaneously be removed. The removed tape is spooled on disposable cores for disposal.

Abstract: An auxiliary heating means for improving the melting efficiency of melter kettles used to melt thermoplastic pavement marking materials. The auxiliary heating means includes a tube assembly through which thermoplastic material received from the bottom of the melter kettle is transferred to the top of the melter kettle. The tube assembly comprises an odd number of tubes having augers therein. The tube assembly is coupled to a side portion of the melter kettle and located within a heat chamber through which hot combustion gases from a combustion chamber at the bottom of the melter kettle flow and transfer heat into the tube assembly. The heat chamber comprises an extended portion of a heat chamber that surrounds the melter kettle.

Abstract: A thermoplastic melter kettle having a heat dome chamber from which combustion gases are exhausted through a conduit that connects between a top of the heat dome chamber and the top of the melter kettle. An adjustable venting arrangement coupled to the conduit allows for adjustment of the flow of exhaust gases through the conduit.

Abstract: An auxiliary heat exchanger that is used in conjunction with thermoplastic melter kettles. The auxiliary heat exchanger receives molten thermoplastic material from the bottom of a melter kettle, transports the molten thermoplastic material though the auxiliary heat exchanger and feeds the molten thermoplastic material into the top of the melter kettle thereby mixing hotter molten thermoplastic material from the bottom of the melter kettle into cooler thermoplastic material near the top of the melter kettle. The auxiliary heat exchanger includes an oil bath chamber and parallel heat transfer tubes that are arranged in a serpentine configuration and include motor drive augers to transport molten thermoplastic material through the auxiliary heat exchanger.
