The method of building and transferring a tread belt structure on a portable and collapsible building drummounted coaxially on a building machinewith a rotatable shaftis disclosed. The method includes the steps of forming the annular tread belton the building drum, transferring the building drumwith the tread beltfrom the rotatable shaftonto a pivoting transfer device, pivoting the transfer deviceabout 90&#xb0; rendering the tread beltand axis of the building drumperpendicular to a horizontal plane, collapsing the building drum, separating the annular tread beltfrom the building drum, removing the tread belt, expanding the tire building drum, pivoting the building druminto coaxial alignment with the rotatable shaft, moving the building drumonto the shaft. The tread belthas one or more elastomeric components applied while hot and the equipment provides means for weighing the tread belt

Method and apparatus for building and transferring a tread belt structure

A method of making a tire mold segment with a porous metal tread surface for a tire mold wherein an annular segmental tire model of refractory material is formed with tire model segments which are used to shape and form each tire mold segment from powdered metal by applying heat and pressure to sinter the powdered metal as it is shaped by the tire model segment. Blades may be mounted in the tire model segments for transfer to the tire mold segments for molding slits a tire tread.
