  • Publication number: 20040123936
    Abstract: A method and apparatus for partial depth-wise cure of a tire inner liner are disclosed. The method comprising forming a layer of uncured rubber, that layer having a first surface and an opposite surface, applying pressure to the layer of rubber, heating the layer of rubber from the first surface to more fully cure the layer on that surface than on the opposite surface, cooling the layer of rubber and releasing the pressure applied to the layer of rubber after the layer has cooled.

  • Patent number: 5313745
    Abstract: A method and apparatus (10) for grinding the edge of a precured tread (100) is described. The method for removing material from and shaping an edge of a precured tread comprises the steps of:a) placing the edge of the tread in a V-shaped groove of a grinding wheel;b) rotating the grinding wheel while it is in contact with the tread edge; andc) moving the tread and grinding wheel relative to one another, the movement being in a direction causing the edge of the tread to be ground to move through the groove in the grinding wheel. The preferred method comprises mounting a winged tread on an apparatus (10) capable of grinding the wing tip of the tread, the apparatus (10) buffing the tread wing (108) such that the wing tip (110) is ground along axially inner and outer surfaces (112,114) a radial distance of at least 5 mm about the circumferential extent of the wing, wherein the inner and outer surfaces (112,114) of the wing tip are ground to form two surfaces that intersect.

  • Patent number: 4808257
    Abstract: A tread splicer (10) including two rows (60,64) of splicing blade assemblies (68) mounted with the blades (76) of one row (60) tilted toward and overlapping the blades (76) of the other row (64). Each of the blade assemblies (68) is operable independently to control the pressure applied to selected portions of the tread ends. Guide rollers (54,56,58) on the tread splicer (10) provide stitching of the tread (14) as well as positioning of the blades (76) relative to the tread (14) and tire building machine drum (18).
