摘要:
A method for manufacturing a self-sealing sealant layer (10) to a pneumatic tire (1) for a vehicle, wherein the vulcanized tire (1) is positioned to a tire rotator device (40) such that the rotational axis (12) of the tire is horizontal and the tire (1) is rotated around said horizontal axis (12), a sealant material is heated to a temperature of 70 - 200 °C, the adhesive sealant strip material (105) is extruded downwards on to an innerliner (11) of the tire by an applicator head (5), the applicator head (5) is extruding the strip material, the applicator head (5) is moved in a traverse direction so that the strips (105) form a substantially continuous sealant layer (10) on a puncture resistivity area (20), a number of revolves of the tire (1) is adapted to a width of the strip (105) so that tire (1) is rotated to form the sealant layer (10). The invention concerns also a corresponding tire.
摘要:
A device (100) for driving antiskid studs (800, 911, 912) into holes (920) of a tread (930) of a pneumatic tire (900). The device (100) comprises a tire holder (210) for holding a pneumatic tire (900) and a studding tool (300). The studding tool comprises a primary and a secondary studding heads (400, 500) both studding heads comprising a mouth (410, 510) for injecting a stud (911, 912) out of the studding head (400, 500) into one of the holes (920) in a direction (D410, D510), a bore (420, 520) for guiding the stud (911, 912), the bore (420, 520) ending at the mouth (410, 420), and a pusher (430, 530) movable in said bore (420, 520) for pushing the stud (911, 912) out from the bore (420, 520). The studding tool (300) and/or the tire holder (210) moves relative to each other at least in a direction that has a non-zero component in an axial direction (AX).
摘要:
A method for making a blind hole in a prefabricated tire and a method for inserting studs into such a blind hole. The steps are arranging available a prefabricated tire comprising tread blocks forming the tread of the tire, and thereafter machining a blind hole into a tread block of the tire so that the blind hole has a first cross section at a first depth and a second cross section at a second depth wherein the second depth is greater than the first depth, wherein the second cross section is greater than the first cross section.
摘要:
A method of inserting an insert (200) - particularly a fragile insert, such as an insert comprising electronic components - to a tread (120) of a tire (100) to be protected against gripping and impact forces during its insertion. The insert (200) being housed, at least partially, in a sleeve (550) upon and during its installation to a tire tread (120). Thus, the sleeve (550) provides protection for the insert (200) against gripping and/or impact forces during the insertion of the insert (200) into the tread (120) a tire (100).
