Provided is a dip molding emulsion including, at least: an elastomer that contains a (meth)acrylonitrile-derived structural unit, an unsaturated carboxylic acid-derived structural unit, and a butadiene-derived structural unit in a polymer main chain; an epoxy crosslinking agent; water; and a pH modifier, in which dip molding composition the elastomer contains the (meth)acrylonitrile-derived structural unit in an amount of 20% by weight to 40% by weight, the unsaturated carboxylic acid-derived structural unit in an amount of 1% by weight to 10% by weight, and the butadiene-derived structural unit in an amount of 50% by weight to 75% by weight, and the epoxy crosslinking agent includes an epoxy crosslinking agent containing an epoxy compound having three or more epoxy groups in one molecule and has a dissolution rate in water of 10% to 70% as determined by a specific measurement method.

An automatic splicing apparatus and methods thereof are provided herein for splicing together two ends of a sheet of tire material on a tire building drum. The apparatus comprises a frame, a splicer foot assembly, and a splicer roller assembly. The frame is configured to support the apparatus relative to the drum. The splicer foot assembly and the splicer roller assembly are independently longitudinally translatable relative to the frame. The splicer foot assembly includes a splicer foot having forward lower preparation rollers and rearward lower splicer rollers, and upper preparation rollers configured to operate in coordination with the forward lower preparation rollers to pull the two ends of the sheet of tire material together over the splicer foot. The splicer roller assembly includes upper splicer rollers configured to act in coordination with the rearward lower splicer rollers to splice the two ends together.

A flexible sheet for neurostimulation is described having a flexible non-conductive substrate matrix in which electrodes are embedded along a lower surface. Electrically conductive wires extend from the electrodes through the flexible substrate to another exterior surface of the substrate. Methods of making the flexible sheet and making a device using the flexible sheet are also disclosed.

A cover for a cushion includes a first panel, a second panel, and a primary receptacle defined between the first panel and the second panel. The primary receptacle may receive a primary cushioning element, such as a pillow, a pillow insert, or a fill material. At least one of the first panel and the second panel includes a secondary cushioning element. The secondary cushioning element may be defined from a compressible, resilient elastomeric material that defines a plurality of thin interconnected walls that in turn define an array of open cells or columns. Each cell or column may have a hexagonal shape, imparting the array of open cells or columns with a honeycomb appearance. Methods for assembling a primary cushioning element with such a cover are also disclosed.

A multilayer core molding method for molding a multilayer core of a golf ball includes an upstream process; and a downstream process, wherein the intermediate molded body includes: an inner core; and an unvulcanized or semi-vulcanized first outer core material, and the downstream process molding apparatus includes: a first downstream process mold including a substantially hemispherical first downstream process mold cavity surface; a second downstream process mold including a substantially hemispherical second downstream process mold cavity surface; and an intermediate plate including a substantially hemispherical intermediate plate cavity surface, and a substantially hemispherical intermediate plate projecting surface, and wherein the downstream process includes: a second outer core arrangement step; an intermediate molded body arrangement; and a preparatory molding step.

Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.

The present invention relates to a method of shaping material having a plurality of interstices (such as a network of voids) and shaped products formed by the method. In preferred embodiments the material is a foam such as a polyurethane foam. The shaping method allows such materials to be shaped using contour-shaping machining methods including computer numerical control (CNC) milling, which is provided by way of example only. To be contrasted with methods of manufacturing a shaped material (such as by the polymerisation of a solution or emulsion of monomers), in several aspects the present invention contemplates the shaping of existing (preformed) materials having a plurality of interstices, such as a network of voids.

Described herein is a method for preparing a molded rubber product comprising a printed label that is integrally molded into the molded rubber product as part of the normal molding process in order to ensure the label becomes an integral part of the final molded rubber product. The printable label may be composed of a rubber based reflective sheeting.
