A method for producing a foamed extrudate comprises a device containing a main melting device and an auxiliary melting device. A first melt is generated in the main melting device, a second melt is generated in the auxiliary melting device from a meltable starting material. At least one reactive additive is added to the meltable starting material, wherein the at least one reactive additive being selected from the group consisting of a chemical blowing agent and an active nucleating agent is mixed in the auxiliary melting device with the second melt, so that an additive-containing second melt is obtained in the auxiliary melting device which is added to the first melt.

An extrusion apparatus intended for the manufacture of a coextruded profiled element P for tyres, produced from rubber compounds of various compositions, comprises a profiling device (30) arranged at the outlet of at least two flow channels (34, 35) for rubbery compounds of different composition. The said channels receive the compounds from positive-displacement contrarotating twin-screw extruders (10, 20), the screw flights interpenetrating and having conjugated profiles.

In particular embodiments, a process for producing bulked continuous carpet filament from recycled polymer utilizes two vacuum pumps (140A, 140B) in combination with a single extruder (100). In various embodiments, the dual vacuum arrangement (e.g., at least two vacuum pumps (140A, 140B)) operably coupled to the single extruder (e.g., MRS extruder (100)) may be configured to remove one or more impurities from recycled polymer as the recycled polymer passes through the extruder.

The invention relates to a method for producing fiber-reinforced composite parts by means of vacuum infusion of a reactive resin mixture, characterized in that the steps of production of the reactive resin mixture and injection into the cavity are carried out in an infusion device in immediate temporal succession.

A device and a method for producing reaction plastics, including a first metering device with a first metering unit and a second metering unit, each of which is suitable for receiving and dispensing a first mixing component in a metered manner, a second metering device which is suitable for receiving and dispensing a second mixing component in a metered manner, and a mixing device which is suitable for receiving and mixing the first mixing component dispensed by the first metering unit and/or the second metering unit of the first metering device and the second mixing component dispensed by the second metering device. For this purpose the first metering unit and the second metering unit are connected to the mixing device such that prior to beginning the mixing process, the first mixing component can be brought to an operating state required for the mixing process, in particular an operating pressure, by guiding the first mixing component from the first metering unit to the second metering unit via the mixing device.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A pad for preventing tire skidding and a manufacturing method thereof, and is to provide a pad for preventing tire skidding and a manufacturing method thereof configured by a friction member formed by mixing a raw material rubber containing butadiene rubber and a functional additive; an adhesive layer coated with an adhesive on one side of the friction member so that the friction member is able to be adhered to a vehicle tire; and a mesh net embedded in the friction member or a mesh net connected to a piezoelectric element. The pad is provided with an adhesive layer coated with an adhesive and can be easily attached and used onto a vehicle tire, and is made of a large amount of butadiene rubber to increase the friction force against the ground.

In the field of tire production, systems and methods utilize a feed belt (150) for directing a rubber mixture from an initial mixing installation (20) toward at least one of two mixing and cooling installations (100, 100′). It is possible to selectively carry out monopassage and multipassage rubber production sequences in a common rubber production facility. A tire is formed according to the methods described.
