Sewing method and apparatus to increase 3D object strength
10920351 · 2021-02-16 · ·

An addition to additive manufacturing sews a number of printed substrate sheets together using industrial sewing machine technology. Portions of the final 3D object that will be solid are sewn together into bundles of the object with a needle protruding through the top of the bundle via a sewing machine with a looping mechanism connecting the thread loops under each bundle of printed substrate sheet layers. This will result in many well connected stack bundles that are then stacked in alignment to form the final stack. During heat and compression, the stitch thread may bunch together and become entangled with the cooled plastic of the final solid 3D object. Removal of the excess substrate may proceed as usual, since the sewing is applied only in the solid portions of the final object. The end result will be a part with much higher strength in the Z axis.

Multi-layered grip
10925271 · 2021-02-23 ·

Disclosed are grips and methods of making grips for use with the handle of an article, and in particular for use with fishing poles and golf clubs. Grips preferably include a multi-layered gripping member and an inner sleeve or mounting body. The gripping member can include an outer layer with a fabric layer coated and preferably saturated by polyurethane. The outer layer can be bonded to an inner layer to form the gripping member which is then attached to the sleeve. The sleeve can be ground from a starting block of material or may be injection molded. Also disclosed are handles including a connector configured to couple to a portion of a fishing pole. Such handles may include a multiple layers and can be selectively removed from the article. Methods are also provided for selectively coupling exchangeable handles to articles including fishing poles.

METHOD FOR MANUFACTURING DECORATIVE LAYER OF VEHICLE INTERIOR TRIM AND VEHICLE INTERIOR TRIM
20210213892 · 2021-07-15 ·

A method for manufacturing a vehicle interior trim decorative layer. The method includes: a die cutting step during which at least two parts to be sewn are die cut from a flat film, each of the at least two parts to be sewn having an outer surface and an inner surface opposite to the outer surface; a gluing step during which an adhesion agent is applied, by means of a roller coating machine, on the inner surface of each part to be sewn, and a sewing step during which all parts to be sewn are sewn together along a sewing line by means of a sewing machine so as to form a 3D shaped decorative layer. The decorative layer can be used with a substrate to form a vehicle interior trim. The method enables manufacturing of a 3D shaped decorative layer using a roller coating machine.
