摘要： A method for producing a retreaded tire 2 includes a step of shaving a tread 104 from a tire 102, a step of attaching a tag member 30 to a formed surface BD made by shaving the tread 104, and a step of reconstructing a new tread 4. The formed surface BD is located radially outward of a maximum width position of the tire 2. The tag member 30 is located radially inward of an end of a belt 14. An initial vulcanization time t10 of a rubber composition for a protector 34 of the tag member 30 is shorter than an initial vulcanization time t10 of a rubber composition for the new tread 4.

摘要： The present invention relates to a pre-vulcanized annular crown of an extra-large tire, and a preparation method and an application thereof. The annular crown includes shoulder extending edges, which extend from both sides of the crown to the central direction of the tire along shoulders, where the shoulder extending edges are provided with a structure of pattern blocks and pattern grooves, which extend from a tread to sidewalls and are suitable for the extra-large tire, and outer contour lines of sections of the shoulders and the shoulder extending edges are concave inwards. Pattern grooves in original shoulders can be completely removed when an old tire body is ground, and the crown structure and functional advantages of the extra-large tire which is retreaded can be fully given.

摘要： A method of retreading a tire. The method includes the steps of applying a primer to an inner surface of a circumferential tread and applying the primer to an outer surface of a tire casing; applying an adhesive to the primer disposed on the inner surface and the primer disposed on the outer surface; applying the circumferential tread to the tire casing so the inner surface contacts the outer surface and a bondline edge forms circumferentially about the tire casing proximate to a shoulder area of the tire casing; and coupling a moisture reservoir to the circumferential tread proximate to the bondline edge.

摘要： A machine for retreading tires includes a rotatable hub that includes a moveable conical element, and an expandable rim disposed around the rotatable hub. The expandable rim includes a plurality of shoes. Each shoe of the plurality of shoes may have a base portion and a rim portion. The base portion may have a two-piece construction that allows for replacement of a worn interface that may include a channel and a ramp. A method for assembling an expandable rim for use in a tire retreading machine, and a method for servicing a machine having an expandable rim are also disclosed.

摘要： 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.

摘要： Mould for moulding a tread of a tire, this tread having a thickness of material to be worn away and a tread surface intended to come into contact with the road surface when the tire is running, this mould having a moulding surface intended to mould the tread surface of the tread, and having a moulding element formed of a blade and a bar, the blade being attached to the moulding surface to mould a sipe in the tread, the bar, borne by the blade to form an enlarged part of maximum width D, being intended to mould a channel in the tread, this channel itself being intended to form a new groove when the tread becomes part worn. Each blade is delimited by two lateral faces forming between them a mean angle of between 6° degrees and 18°. The blade width decreasing from the mould surface when new, as far as the connection with the bar, the blade width meets the bar being at least equal to between 0.2 and 0.4 times the maximum width D.
