The present disclosure relates to systems and methods relating to the application of composite radius filler materials. An example material feed system includes a material container configured to contain a composite material and a material feed actuator. The material feed system also includes a nozzle coupled to the material container and a workpiece sensor configured to provide information about a workpiece. The material feed system also includes a controller. The controller is configured to receive, from the workpiece sensor, workpiece information. The workpiece information is indicative of at least one surface of the workpiece. The controller is also configured to, based on the workpiece information, cause the material feed actuator to apply a force to the composite material contained in the material container so as to extrude at least a portion of the composite material out of the nozzle and onto a surface of the workpiece.

An extrusion device (100) for forming as a thin strip a product based on a rubber mixture includes: a rotating roller (112) with a groove (112R) in the form of a continuous helix made on the outer surface (112a) of the roller, the groove including several striations (112Ra) arranged one beside the other in the direction of movement of the mixture, and the striations being spaced apart from one another so as to create a thread of predetermined pitch; and a vault bearing, on its inner surface oriented towards the roller, projecting threads so as to delimit with the surface of the roller a chamber for plasticizing the mixture The roller and the vault are assembled such that thread crests created by the helix and the crests of projecting threads on the vault are substantially in contact with one another.

A system for making a tire tread includes an extruder, a roller die having a first axis of rotation, and a conveyor that receives a round strip (or noodle) of green rubber from the extruder and feeds the strip of green rubber to the roller die. The system further includes a drum having a second axis of rotation, wherein the roller die is configured to apply the strip of green rubber to the drum. The system also includes a controller, wherein the controller is configured to control a translation of the roller die in a first direction parallel to the first axis of rotation. The controller is configured to control a roller die rotation speed and a drum rotation speed, and the controller varies at least one of the roller die rotation speed and the drum rotation speed during translation of the roller die.

A system for additively manufacturing a composite part is disclosed. The system may include a vat configured to hold a supply of resin, and a build surface disposed inside the vat. The system may also include a print head configured to discharge a matrix-coated continuous reinforcement onto the build surface, and an energy source configured to expose resin on a surface of the matrix-coated continuous reinforcement to a cure energy.

A toy building block base comprises a flexible elongate body strip having a first major surface along a length of the strip that includes either an array of projections extending from the first major surface or an array of recesses set into the first major surface. The projections or recesses form a mating arrangement for co-operant toy building blocks. An opposite, second major surface has an adhesive by which the body strip can be attached to a support surface. The body strip includes no more than four projections or recesses across its width and has a length of at least 200 mm. The entire body strip is made from a homogenous flexible plastics material.

A process for producing tyres including building a green tyre having two bead structures. Each bead structure includes a bead filler. The bead filler or another rigid component of the green tyre includes a final elastomeric compound produced by the following: feeding elastomeric polymer and reinforcement filler to a first batch mixing device; mixing and dispersing the reinforcement filler in the elastomeric polymer and unloading the obtained elastomeric compound; feeding the obtained elastomeric compound, along with at least 5 phr of reinforcement resin, to a continuous mixing device of intermeshing and co-rotating twin-screw or multi-screw type or of planetary type; mixing the reinforcement resin in the elastomeric compound and unloading the obtained elastomeric compound; and feeding the obtained elastomeric compound along with the components capable of facilitating the cross-linking to a second batch mixing device and mixing to obtain the final elastomeric compound. The first and second batch mixing device have two counterrotating rotors.
