METHOD OF MANUFACTURING LATEX RUBBER ARTICLES
20230145646 · 2023-05-11 ·

A method of manufacturing a latex rubber article comprises providing a former wherein at least a part of the former comprises a mould surface that forms the shape of the latex rubber article, and applying liquid latex to the mould surface using an applicator that is configured to apply the liquid latex to an applicator area that is smaller than the mould surface. The method further comprises providing relative movement between the applicator and the former to produce a latex coating that covers the mould surface, curing the latex coating on the former to form the latex rubber article, and removing the latex rubber article from the former.

Fluid Transfer Assembly, A Fluid Transfer System, and a Related Method

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.

Stripping of a dip-moulded glove from a former

Glove stripping apparatuses for fully stripping a partially stripped elastomeric dip-moulded glove from a dip-moulding former comprises a gripper having first and second gripping members movable relative to each other, an abutment, an open space, and an actuation system. Also, production lines for producing elastomeric dip-moulded gloves, methods for fully stripping gloves from dip-moulding formers, and production line processes.

MOUNTING AND DEMOLDING DEVICE
20170320244 · 2017-11-09 ·

A demolding device for use in an imprint machine, in which machine a foil is intermittently passed in a feed direction over a press region where a stamp is pressed against the foil for imprinting a surface pattern. The demolding device includes a carrier, a pressing roller mounted in the carrier, and a demolding roller mounted parallel to the pressing roller in the carrier, wherein the carrier is configured to slide over the press region against the feed direction while rolling the foil under the pressing roller and over the demolding roller for detaching the foil from the stamp after imprinting of the pattern.

Stripping of a dip-moulded glove from a former

A glove stripping apparatus (15) for fully stripping a partially stripped elastomeric dip-moulded glove (2) from a hand-shaped dip-moulding former (4) comprises a gripping device (25) relatively movable with respect to a downwardly hanging cuff end portion (10), a gripping actuator (32), a stripping actuator (35) and a controller for controlling the operation of the actuators. The relative movement of the gripping device and the downwardly hanging cuff end portion is driven by the stripping actuator. The gripping device has first and second gripping members (24, 26) movable relative to each other by the gripping actuator. The gripping members provide opposed gripping surfaces (34, 36) for gripping the cuff end portion. The first gripping member and the second gripping member initially provide a horizontally extending gap between the gripping surfaces which receives the cuff end portion. The gripping members are moved to reduce the gap (40′) until the cuff end portion is restrained between the gripping surfaces with a beaded cuff end (3) of the glove being below the gap. The gripping members are moved downwardly (46) together towards the beaded cuff end so that the cuff end portion moves upwards relative to the gap until the beaded cuff end (3) is caught by the gap (40′). The downward movement is then continued until the glove is fully stripped from the dip-moulding former.

MOLD PART USED FOR INJECTION MOLDING OF THERMOPLASTIC RESIN AND INJECTION MOLDING METHOD OF THERMOPLASTIC RESIN

Provided is a mold part which does not generate periodic irregularities (scale pattern) which appear in the direction orthogonal to the drawing direction (MD) of the mold part having a surface which slides parallel to a molded article when the molded article is removed from the mold after injection molding during injection molding of a thermoplastic resin (in particular, a thermoplastic fluoropolymer), an injection molding method using the same, and a molded article in which periodic irregularities (scale pattern) (which appear in the direction orthogonal to the drawing direction (MD) of the mold part) do not appear. The mold part is used for injection molding of a thermoplastic resin, and includes a surface which slides substantially parallel to a molded article when the molded article is removed from the mold after injection molding, wherein the average tilt angle in the sliding direction (MD) is 1.5° or higher.
