10124515 · 2018-11-13 · ·

A pillow is provided that includes a foam core and a gel insert molded to each side of the foam core. Methods of producing a pillow are further provided and include a step of providing a foam molding system having a top mold defining a plurality of air ports and a bottom mold defining a plurality of air ports. A vacuum is applied to the plurality of air ports in both the top mold and bottom mold, and a gel insert is then positioned against each of the plurality of air ports. A foam precursor is subsequently dispensed into the bottom mold atop the gel insert, and the top mold is secured to the bottom mold. The foam precursor then expands within the foam molding system and bonds with the two gel inserts to produce a pillow having a gel insert molded to each side of the pillow.

Wire-reinforced tubing and method of making the same

An apparatus for and method of manufacturing an improved wire-reinforced plastic tubing for medical and other applications is disclosed. A plurality of spaced-apart wire segments may be wound onto successive portions of a long segment of plastic tubing which portions are supported for rotation to wind coil wire thereon by rotating the plastic tubing while a supply of coil wire is wound onto the plastic tubing. When multiple winding segments have been wound on the long segment of plastic tubing, the segments may be separated into individual wire-reinforced tubing products each having one or more wire windings thereupon.

The negative mold includes a support structure and a plurality of foam blocks, which are mounted to the support structure in such a manner, that a common surface contour of the plurality of foam blocks defines an outer surface of the component, which is to be casted. Each foam block of the plurality of foam blocks is taken from a predetermined number of different types of foam blocks, each type of foam block is defined by a predetermined foam block size and foam block shape. A method for producing such a negative mold is also described.

Method for making a hollow object
10112357 · 2018-10-30 · ·

Method for manufacturing a hollow object from a material comprising threads mechanically linked to one another to form a first shell. The method comprises a reference step that involves shaping the first shell on a support, a first step, subsequent to the reference step, that involves covering the first shell with a sealed membrane and obtaining a pressure difference on opposite sides of the membrane, the pressure on the side of a surface of the membrane in contact with the first shell being less than the pressure on the side of a free surface of the membrane, and a second step, simultaneous with and/or following the first subsequent step, that involves causing a change of state and/or the bonding of some or all of the threads forming the first shell.

APPAREL AND SPORTING EQUIPMENT WITH AN UV RADIATION CURABLE MATERIAL AND METHOD OF MANUFACTURING THEREOF

An article of apparel or sporting equipment, such as garments and footwear incorporates a molded component formed of a UV radiation curable material. In the case of an article of footwear, the UV radiation curable material may be formed into an outsole. The method of manufacturing such articles include placing an ultraviolet radiation curable material in contact with a molding surface; conforming the UV radiation curable material to a shape of the molding surface, forming a molded component; and removing the molded component from the molding surface, such that the component maintains the shape of the molding surface. The molded component may be exposed to ultraviolet radiation in an amount and for a duration that is sufficient to partially cure or fully cure the UV radiation curable material.

ARTICLES AND COMPONENTS WITH UV RADIATION CURABLE ELASTOMERIC MATERIALS AND METHODS OF MAKING THE SAME
20180305581 · 2018-10-25 · ·

20180244001 · 2018-08-30 ·

A template made of plexiglass or similar material is inserted into a cover for a protective helmet so that the cover is stretched and once the template is inserted the assembled combination of the cover and the template is oval-shaped. The oval-shaped assembly is placed on top of the bottom plate of a heat press. A layer with a decal or sticker is placed on top of the oval-shaped assembly. A heat press cover sheet is then placed on top of the oval-shaped assembly so that it also becomes into contact with the top plate of the heat press when the heat press is closed. The heat press may be set to a temperature of at least 350 degrees Fahrenheit and it can be set in a closed position for at least 10 seconds in order to transfer sufficient heat so that the decal or sticker is applied or affixed to the cover surface.
