A method and a device for manufacturing a rubber coated cord, comprising:

a rubber coated cord including a preceding cord is manufactured by causing the preceding cord to pass through a preceding head while filling the preceding head with unvulcanized rubber extruded from a rubber extruder, and a rubber coated cord including a next cord is manufactured by setting a leading edge portion of the next cord in a state where the leading edge portion of the next cord has passed through the next head in advance, manufacturing a predetermined length of the rubber coated cord including the preceding cord, and subsequently causing the next cord including a leading edge portion side range bonded to a trailing edge portion of the rubber coated cord including the preceding cord to pass through the next head while switching from the preceding head to the next head.

The present application relates to an elastomeric article, such as a glove, comprising: (i) an elastomeric film comprising one or more film layers, and including an external surface and an internal surface, (ii) an antimicrobial agent that is effective against both beneficial and harmful microorganisms on the external surface of the elastomeric film, and (iii) a skin-protective agent selected from a probiotic, a prebiotic, or a combination thereof on the internal surface of the elastomeric film; wherein the inner surface of the film is free of an antimicrobially-effective amount of an antimicrobial agent that is effective against both beneficial and harmful microorganisms. The elastomeric articles may further comprise a barrier film layer that provides separation between the antimicrobial agent and the skin-protective agent. Also described are methods for the manufacture of such articles.

A method of forming a shoe upper includes obtaining a mold defining a shoe component, spraying a polymer formulation onto the mold to form a sprayed polymer formulation layer, curing the sprayed polymer formulation layer to form a polymer film, removing the film from the mold, and incorporating the film into the shoe upper.

Systems and methods are disclosed that include an operation chamber, a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to a profile formed by cutting a piece of tubing, and a mechanical motion module. The plasma generator generates a plasma treatment and applies the plasma treatment via the at least one plasma head to the profile to activate material on an end surface of the profile, within a lumen of the profile, or a combination thereof. Once the material of the profile is activated by the plasma treatment, the mechanical motion module manipulates the profile to close the lumen of the profile to aseptically seal the profile.

A balloon (10) extending generally axially from an opening (14) at a first end. The balloon comprises an elastomeric film (11) having a first thickness and a plurality of intersecting ribs (12) of a second, greater thickness formed on the film. The ribs are adapted so as to be angled with respect to the axis (13) of the balloon and any axis perpendicular thereto. Such a balloon has increased tear resistance, and can be manufactured with conventional dipping techniques without compromising the integrity of the film. The ribs may comprise a plurality of helices. There is also a former for making such a balloon and a method of using such a former to make such a balloon.

According to the present invention, devolatilization of a synthetic resin formed from a polymer or synthetic rubber can be improved and the synthetic resin can be foamed at a low temperature by injecting a devolatilization agent through a devolatilization agent injection nozzle provided in a downstream end segment cylinder of a cylinder assembly. In a vented twin-screw kneading extrusion apparatus and extrusion method according to the present invention, a devolatilization agent, which is injected through a downstream end devolatilization agent injection nozzle provided on a downstream end segment cylinder constituted by a segment cylinder positioned on a downstream end of a cylinder assembly, is dispersed in molten resin in the downstream end segment cylinder and kneaded by a downstream end kneading portion such that the molten resin is foamed by the devolatilization agent and then extruded.
