An autoclave suitable for use for heating articles such as tires is described. The autoclave includes an elongated chamber having an interior section and an annular duct surrounding the interior section, wherein the annular duct is separated from the interior section by a dividing wall; said autoclave further including a heat source for heating the air, a fan for circulating the air in the chamber, and an air deflector mounted in a distal end of the chamber. The air deflector is positioned to redirect the airflow towards the interior portion of the chamber to eliminate air recirculation zones and improve the temperature uniformity.

The present invention is directed to a method of retreading a pneumatic tire, comprising the steps of: A) mixing a tire retread cushion laminate of to form a cushion compound, the tire retread cushion laminate comprising a first rubber layer, a second rubber layer, and an intermediate rubber layer disposed between the first and second rubber layers such that the first and second rubber layers do not meet; the first rubber layer comprising a sulfur donor and substantially devoid of vulcanization accelerators; the second rubber layer comprising a vulcanization accelerator and substantially devoid of sulfur donors; the intermediate rubber layer being substantially devoid of sulfur donors or vulcanization accelerators; B) applying the cushion compound to a tire carcass; and C) applying a tread portion to the cushion compound.

A rubber track T has a plurality of guide lugs arranged in two rows, one row being on each lateral edge. The guide lugs of the first row are circumferentially offset from the guide lugs of the second row. The track T is molded on an axially separating mold core D that is designed to form the radially inner guide lugs without requiring a radially collapsible core.

Track design

A pneumatic tire wheel assembly for tracked vehicles has a unique rim assembly for dual wheel mounting. The rim assembly has a pair of annular rims connected by a plurality of laterally extending spokes or . The spokes or enable mud and debris to pass preventing the accumulation of debris, mud, or snow between the wheel and the track.

This invention relates to an annular elastic track for use in vehicles for civil engineering, construction works and agricultural works. The track has a plurality of spaced rubber tread lugs , each having a first lateral end portion B, a middle portion M and a second lateral end portion C, each portion B, M and C being oriented perpendicular to the circumferential direction wherein the middle portion M is projected forward relative to the lateral end portions B and C.
