Abstract: A sculptured drum for a retread process that has an inner radial section with a central axis that extends in an axial direction. The sculptured drum has a plurality of support members that extend outward from a drum outer surface in a radial direction and that are located outward from the inner radial section in the radial direction. A tread that has a plurality of grooves is supported by the sculptured drum during a brushing process and pass across the sculptured drum such that some but not all of the grooves have one of the support members disposed therein. The support members when disposed within the grooves do not completely fill the grooves, and when disposed within the grooves engage a lower surface of the tread.

Abstract: A tread extension device (10) is provided that has first (12) and second (14) tread extensions for holding a tread during brushing operations. A first connecting device (28) connects the first tread extension (12) to a first longitudinal end (18) of the tread, and engages both the first tread extension (12) and the first longitudinal end (18) of the tread. A second connecting device (30) is included that connects the second tread extension (14) to the second longitudinal end of the tread. The second connecting device (30) engages both the second tread extension and the second longitudinal end of the tread. The tread is able to be brushed in both a first direction and a second direction along its underside.

Abstract: Embodiments include a mud flap having a barrier section configured to intercept and deflect matter discharged from the tire when rotating during vehicle operation. The barrier section including a plurality of horizontal louvers, each horizontal louver forming an elongate member having a length extending primarily in a direction of the mud flap width, where the plurality of horizontal louvers are spaced apart in the direction of the mud flap height in the form of an array, where the plurality of horizontal louvers are configured to intercept and deflect matter of a minimum size traveling along any linear trajectory path from the outer circumference of the tire/wheel assembly towards the front side of the mud flap while substantially maximizing the spacing between adjacent louvers to minimize aerodynamic drag. Other embodiments provide a method of using the mud flap.

Abstract: A fairing for a back end of a trailer is provided that has a leading airflow surface oriented within an angular range from 5 degrees to 14 degrees to a surface of the trailer to which the fairing is attached. The angular range is oriented so that its arms extend rearward from a vertex of the angular range in a longitudinal direction of the trailer. A tailing airflow surface is present that engages the leading airflow surface at meeting location. The tailing airflow surface is curved, and a common tangent line of the tailing airflow surface and the leading airflow surface is at the meeting location. A frame engages the surface of the trailer to which the fairing is configured to be attached.

Abstract: A system for the continuous extrusion, molding, and curing of tread rubber is provided. A plurality of discrete mold sectors are arranged adjacent to each other along a longitudinal axis between an in-feed and an out-feed of a mold sector transport mechanism that extends through a heated press. As the mold sectors are continuously advanced along a process direction in steps, rubber material is extruded and placed onto at least one of the mold sectors near the in-feed end such that an elongated strip of rubber material extends over multiple mold sectors along the longitudinal axis. As the strip of rubber material exits the press, the mold sectors are sequentially removed from the rubber material and returned to the in-feed. An extruder outlet positioned near the in-feed can be moved towards or away from the mold sectors to supply rubber material and prevent backflow.

Abstract: The subject invention includes methods and apparatus for joining treads. Such methods include the step of providing a first tread portion and a second tread portion for forming a joined tread, each tread portion comprising a section of tire tread extending lengthwise from a terminal end. Additional steps include providing a first fixture configured to retain the first tread portion and a second fixture configured to retain the second tread portion and securing the first tread portion into the first fixture and securing the second tread portion into the second fixture, each of the first and second fixtures being arranged within the first and second fixtures such that the terminal end of each tread portion is in communication with a joining side of each fixture. The methods further include directing the terminal ends towards each other and into forceful engagement with an elastomeric joining material arranged between the terminal ends.

Abstract: A tread support device (10) for a retread process is provided that has a first support roller (12) that rotates about a first support roller axis. A second support roller (16) is present that rotates about a second support roller axis. A third support roller (20) is also included that rotates about a third support roller axis. The first support roller (10), the second support roller (12), and the third support roller (20) all support a tread (24). Also in the tread support device (10), the first support roller axis, the second support roller axis, and the third support roller axis are arranged with respect to one another so as to be located on a circumference of a circle (32).
