11826945 · 2023-11-28 · ·

Systems and processes for thermoforming an article and for preparing an article for thermoforming are disclosed. The system for thermoforming can include one or more heating stations and a cooling station. The system for thermoforming can further include an article movement mechanism that can couple to an article and rotate the article inside a heating chamber, inside a cooling chamber, or both. The system for preparing an article for thermoforming can include a vessel that comprises a port, and a negative pressure generation system coupled to the port. The system for preparing an article for thermoforming can further include a compression material that forms an interior portion for receiving an article. The negative pressure generation system can cause the compression material to expand to allow for insertion of the article into the interior portion of the compression material.

Thermoplastic forming tool
11518115 · 2022-12-06 · ·

A thermoplastic forming tool includes a wand that includes a handle, a tip, and a conduit coupling the handle to the tip. The tip includes a heating element, a forming shoe, and a forming shoe support. During use, heat from the heating element heats the forming shoe to a temperature at or above the glass transition temperature of a thermoplastic polymer. The thermoplastic forming tool may be used to apply a thermoplastic material to a surface.

Method for hot-forming a thermoplastic material and implementation facility

A method for shaping a preform made from thermoplastic material, and a facility for implementing the method, comprising the following steps: a) providing a preform made from thermoplastic material having a surface; b) supplying thermal energy to the preform by radiation in such a way as to make it ductile; and c) shaping the ductile preform inside a forming mould. Step b) further involves simultaneously spraying a gaseous fluid onto the surface of the preform in order to preserve the surface.

ARTICLES OF WEAR AND PROCESSES FOR MAKING THE SAME

Processes and systems for thermoforming articles of wear are disclosed. The process can include utilizing a negative pressure generation system to seal an article in a forming material thereby compressing the forming material onto the outer surface of the article. The process can also include exposing the sealed article to an increased temperature followed by exposure to a decrease temperature, while maintaining the compressive force of the forming material on the outer surface of the article. A positive pressure can also be applied to the sealed article while undergoing the heating and/or cooling steps, which can facilitate the removal of bubbles from the article during thermoforming as well as apply additional compressive force to the outer surface of the article.

THREE-DIMENSIONALLY THERMO-MOLDED FOOTWEAR

Articles of footwear including a thermo-molded upper having a skin composed of one or more low melting point thermoplastic polymers. The skin may include at least one of: a base layer composed of a low melting point thermoplastic polymer and a grid layer including a yarn composed of a low melting point thermoplastic polymer. The uppers may be formed by placing a skin and an inflatable bladder into a mold cavity and heating the mold to a predetermined temperature. The inflatable bladder may be inflated such that the skin is pressed against an interior surface of the heated mold cavity to cause the skin to take on the shape of the internal surface of the mold cavity, thereby forming an upper for an article of footwear.

Assembly for manufacturing fillable containers and a packaging line comprising such manufacturing assembly and a corresponding method

An assembly for manufacturing containers by thermoforming, which includes a magazine of thermoplastic sheet-like blanks, a feeding station for feeding the blanks, a heating station for heating the blanks, and a station for thermoforming containers starting from the blanks. The feeding station includes a closed-loop path and at least two conveyor elements, which move, following each other, along the path between a loading position, in which the conveyor element faces the blank magazine, and an unloading position, in which the conveyor element faces the heating station. The heating station includes a heating carousel, wherein, in the active condition, the conveyor element in the unloading position moves with a substantially linear motion with a speed that is substantially equal to a peripheral speed of the heating carousel.

SHAPED OPTICAL FILMS AND METHODS OF SHAPING OPTICAL FILMS

An optical film includes a plurality of polymeric layers shaped along orthogonal first and second directions. A first curve being an intersection of the optical film with a first plane orthogonal to the second direction and to a reference plane has a best-fit first circular arc subtending a first angle at a center of curvature of the first circular arc of greater than 180 degrees where the optical film has a maximum projected area in the reference plane. A second curve being an intersection of the optical film with a second plane orthogonal to the first direction and to the reference plane has a best-fit second circular arc subtending a second angle at a center of curvature of the second circular arc of at least 30 degrees. Reflectance and transmittance of the optical film are described.

Flat flexible hose for transporting fluids
20220275885 · 2022-09-01 ·

A flat flexible hose for transporting a fluid, for example water, is adapted to move between an inoperative position having a flattened configuration and an operative position, in which the hose expands radially under pressure from the fluid. The hose has a first inner layer defining an axis, a second covering layer, and a reinforcement textile layer therebetween. The first and second layers are made of a first and respectively a second thermoplastic elastomeric material adapted to adhere to each other. The reinforcement textile layer is made of rigid textile yarns which at least partially have a respective first and second predetermined inclination opposite to each other so that the length of the hose remains unchanged both in the inoperative and the operative positions. The reinforcement textile layer is a knitted layer with tricot chain stitches with rows of stitches and courses of stitches made of chain stitches.
