A secondary shredder can include a rotor assembly that employs a modular rotor design. Each rotor of the rotor assembly can include a number of blades that are symmetrical around a horizontal and a vertical axis. Each rotor can include a number of radial extensions forming gaps into which the blades insert. The blades can be secured within the gaps by wedges that apply an inward force against the blades when the wedges are secured into the gaps. The radial extensions and blades can include keyways into which keys insert to prevent the blades from escaping the gaps. The secondary shredder may also include a stationary knife assembly that includes multiple stationary knives that are positioned on the same side of the rotor assembly.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

A bicycle tire repair device has a main body which has a first end forming a working end useful for repairing and fluidly connecting with a tire to be repaired and a second end forming an air inlet end useful for connecting with an object that outputs air. The main body defines a channel between the first and the second ends for allowing the air from the object to flow to the second end. The first end includes a tire repair needle connected therewith.

A mold heating device for heating a tire mold (M) for a green tire (T) includes an upper ring member (11) and a lower ring member (12) arranged so as to face one other in a specific direction with the space in which the tire mold (M) is disposed therebetween. A plurality of nonmagnetic members (13) are disposed at a plurality of positions aligned in the circumferential direction of the ring members (11, 12) with spaces therebetween so as to connect the upper ring member (11) and the lower ring member (12). Ferromagnetic non-conductive members (14) are provided on the inner surfaces of the nonmagnetic members (13), and a coil (15) is supported by the nonmagnetic members (13) with the ferromagnetic non-conductive members (14) therebetween so as to surround the space where the tire mold (M) is disposed from the outside in the direction perpendicular to the specific direction.

The invention relates especially to a self-adhesive film 1 for fixing an elastomer patch 10 during a vulcanization of an elastomer component. The elastomer component can in particular be a motor vehicle tire 40 or a cavity lining 120. The film 1 can comprise a supporting layer 2 and an adhesive layer 3. The adhesive layer 2 can have a predetermined manufacturing adhesiveness at room temperature and ambient pressure and a predetermined peel strength at a vulcanization pressure and a vulcanization temperature.

The present application discloses a sealant container and a tire repair and inflation device using the sealant container. The sealant container comprises: a container body having an internal space for storing sealant and a container mouth with an inner wall; and a core component installed onto the container mouth and extending toward the internal space after installation. The core component has an outer end, an inner end, and a first channel between the outer end and the inner end inside the core component for passage of gas, wherein the outer end is provided with an interface, and the inner end is provided with at least one openable outlet to communicate with the internal space when the outlet is opened; and wherein the inner wall further defines a second channel for passage of sealant. The sealant container has a simplified structure and good sealing performance.

Apparatus for introducing air and/or sealant into a tire includes a container for the sealant having an inlet and an outlet, wherein the outlet is connectable to the inlet end of a hose whose outlet end is connectable to the tire to be filled and includes a pressure generation means which can be selectively connected to the inlet of the container or to the inlet end of a hose whose outlet end can be connected to the tire to be filled. The same hose is provided for the connection between pressure generation means and the tire to be filled, on the one hand, and between the outlet of the container and the tire to be filled, on the other hand, with respective couplings being provided at the pressure generation means, the inlet of the container, and the outlet of the container and at the inlet end of the hose which selectively enable the inlet end of the hose to be connected directly to the pressure generation means or the inlet of the container to be connected to the pressure generation means and the inlet end of the hose to be connected to the outlet of the container.

A portable compressor for a tire repair kit comprises an adaptor mobile or removable from a force transmitting use position, the adaptor having an upper edge projecting with respect to an outer side wall of the compressor and defining a seat for a container of sealing fluid, the upper edge being spaced in use from a surface on which the compressor rests; and being configured to define a side support by means of a force transmission to the compressor to oppose an excessive inclination of the container of sealing fluid during the injection of sealing fluid by means of pressurized air.

A topping sheet forming method includes: feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yams; cutting off the weft yarns at a predetermined widthwise position to divide the textile original fabric into a plurality of narrow textile original fabrics; and topping at least one surface of the narrow textile original fabric with unvulcanized rubber.

A topping sheet forming method includes: a feeding and division step of feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yams, and cutting off the weft yarns in predetermined widthwise positions to divide the textile original fabric into a plurality of narrow textile original fabrics; a calender step of topping, with unvulcanized rubber, at least one surface of one narrow textile original fabric out of the divided narrow textile original fabrics; and a wind-up step of winding up the other narrow textile original fabrics out of the divided narrow textile original fabrics.
