  • Patent number: 10882225
    Abstract: A system for the continuous extrusion, molding, and curing of tread for tires. An elongated strip of rubber material can be molded and cured shortly after extrusion such that the material retains much of the heat energy of extrusion and does not have to be stored. A plurality of discrete mold assemblies are conveyed adjacent to each other. As the mold assemblies are advanced sequentially, the uncured and unmolded strip of rubber material are extruded and positioned onto the mold assemblies. While the rubber strip advances, individual portions are sequentially molded and cured by passing through a mold press and then a curing press. A plug assembly is used to prevent the backflow of rubber material during the molding and curing.

  • Patent number: 10493711
    Abstract: A system for the continuous extrusion, molding, and curing of tread rubber is provided. A plurality of discrete mold sectors are arranged adjacent to each other along a longitudinal axis between an in-feed and an out-feed of a mold sector transport mechanism that extends through a heated press. As the mold sectors are continuously advanced along a process direction in steps, rubber material is extruded and placed onto at least one of the mold sectors near the in-feed end such that an elongated strip of rubber material extends over multiple mold sectors along the longitudinal axis. As the strip of rubber material exits the press, the mold sectors are sequentially removed from the rubber material and returned to the in-feed. An extruder outlet positioned near the in-feed can be moved towards or away from the mold sectors to supply rubber material and prevent backflow.

  • Patent number: 9821524
    Abstract: A method for manufacturing a raw blank of a tyre includes using a calender to produce a ply. The calender includes two rollers with a gap situated therebetween. A ply that includes a first rubber material is formed in the gap of the calender, with a bead of the first rubber material being formed upstream of the gap. The bead and the gap of the calender are fed with a second rubber material, different from the first rubber material, to form at least one insert in the ply.

  • Publication number: 20170246788
    Abstract: A nozzle is provided for controlling the flow of extruded material, such as e.g., rubber material, from an extrusion machine. Movable pins are positioned into the path of material flow through an internal cavity. The pins are arranged across the path of flow upstream of the extrusion die. By moving the pins in and out, the flow of material through the cavity can be controlled at different locations across the width of the path of flow to the die. Manual and automatic controls can be provided for determining the position of the pins and thereby controlling the flow.

  • Patent number: 6586190
    Abstract: A parallel high throughput method and kit for the discovery of small molecule interactors of target proteins, in particular, target proteins expressed from entire genomes or subsets thereof. The target module is prepared by binding selectively a target protein, modified to allow its detection, to a surrogate ligand that is linked to an individually detectable bead. Sets of target modules are mixed together in each chamber of a multi-chamber container. A test compound or collection of test compounds is added to each chamber, and the interaction of a compound with each target module is observed. A compound that is specific for a particular target protein will displace that protein from its target module. The identity of the target module so disrupted is determined by identifying the particular bead to which the displaced target protein was attached.
