Footwear component tooling for use with microwave energy
11033080 · 2021-06-15 · ·

The utilization of heat in the manufacturing of footwear may be accomplished through microwave energy. The microwave energy is conveyed to the footwear components through a microwave transparent window of a tool. The microwave transparent tool window forms as least a portion of a part-contacting surface of the tool. Another surface of the tool is formed from a microwave reflecting material, such as aluminum. The footwear component(s) are exposed to microwave energy while within the tool such that the microwave energy passes through the tool window to cause a dielectric heating of one or more materials within a tool cavity of the tool.

Elastomer adhesive with rapid tack development
10975275 · 2021-04-13 · ·

An adhesive composition having two distinct reaction mechanisms, a first being the reaction between a tri-functional isocyanate and an active hydrogen compound and a second begin the free radical initiation of an acrylic monomer. This adhesive develops tack strength through the first reaction allowing two substrates to remain in position relative to one another while the free radical cure of the acrylic monomer takes place to fully bond the substrates together, for example when adhering a rubber liner to the inside of a metallic tank.

BLOW MOLDING METHOD, COMPOSITE PREFORM, COMPOSITE CONTAINER, INNER LABEL MEMBER, AND PLASTIC MEMBER

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.
