A method of forming a composite panel includes providing an initial composite material, heating the initial composite material, molding the initial composite material to form a preliminary composite panel having a main body connected to an outer edge and a laminate layer secured to the outer edge, and folding an exterior edge portion of the outer edge over an interior edge portion to provide an external folded edge having the laminate layer on at least a portion of an outer surface.

Assembly and method for sealing a bundle of wires

A sealing assembly for sealing a bundle of wires includes a first sheet formed of a sealant material, a second sheet disposed above the first sheet, and a third sheet disposed above the second sheet formed of the sealant material. The second sheet includes a thermally conductive material. When the bundle of wires is overlaid on the assembly in a first direction, and the assembly is wrapped in a second direction that is generally perpendicular to the first to thereby surround the wires, the second sheet facilitates enhanced thermal energy distribution of applied heat throughout the assembly to thereby more uniformly melt the sealant material and thereby fill voids between the wires.

11046065 · 2021-06-29 · ·

Embodiments provide a lamination machine and lamination process for laminating a membrane to a three-dimensional (3D) target surface of an article, such as a footwear article, glove, clothing article, backpack, or other article. The lamination machine may include an inflatable former that is permeable to air. The inflatable former may have a shape that generally corresponds to a shape of the target surface. The membrane and target surface may be arranged on the former, with a heat-activated adhesive disposed between the membrane and the target surface. The lamination machine may further include a pump to pump heated compressed air into the former. The heated compressed air may inflate the former to press the membrane against the target surface and to activate the adhesive to bond the membrane to the target surface.

SYSTEMS AND METHODS FOR IN SITU MANUFACTURING OF MINIMALLY TOOLED STRINGERS
20210179293 · 2021-06-17 · ·

Provided are systems and apparatuses for manufacturing aircraft support structures. An example robotic end effector comprises a rotatable reel with a flat strip of material wound around the reel. The end effector further includes a forming shoe including a forming surface contacting the strip of material. A first end of the forming surface corresponds to a start shape and a second end of the forming surface corresponds to an end shape. As the strip of material passes from the first end of the forming surface to the second end of the forming surface, the strip of material transitions from the first shape to the end shape and is deposited as a formed stringer ply onto an application surface. The forming shoe may further include a vacuum system to suction air through a plurality of ports along the forming surface to urge the strip of material against the forming surface.

APPARATUS AND METHOD FOR PRESSING A WORKPIECE
20210260814 · 2021-08-26 · ·

An apparatus for pressing a multi-layered skateboard deck having a variation in thickness is provided. The apparatus includes a mold assembly, a first liner, and a second liner. The mold assembly includes a first mold having a first surface and a second mold having a second surface. The first surface and the second surface are configured to collectively define a mold cavity configured to receive the multi-layered skateboard deck. The first liner is disposed adjacent to the first surface and the second liner is disposed adjacent to the second surface. The mold assembly is configured to apply a load when the multi-layered skateboard deck is disposed in the mold cavity. At least one of the first liner or the second liner is configured to deform in response to the applied load such that the multi-layered skateboard deck is compressed with a substantially uniform pressure.

CONSTRUCTION OF TUBULAR ASSEMBLIES

A method and apparatus for constructing a tubular assembly 40 comprising an inner portion (24) and a further portion (23) surrounding the inner portion. The inner portion (24) comprises reinforcement (37) and the further portion (23) being formed from a strip (50) of material comprising two opposed longitudinal marginal side portions (53). The apparatus comprises an assembly station (220) comprising a wall (253). The apparatus comprises means for advancing the inner portion (21) along a first path (231) extending passed the wall (253), and means for advancing the strip (50) along a second path (232) and causing the strip to encircle the wall (253) and thereby wrap about and surround the inner portion (21). The apparatus further comprises means (321) for introducing resinous binder into the reinforcement (37) as the strip (50) is being wrapped about the inner portion (21).

METHOD AND INSTALLATION FOR JOINING A COVER LAYER TO AN OBJECT
20210162675 · 2021-06-03 ·

A cover layer is joined to an object by a pressing force and mechanical vibration. The cover layer has a cover layer contact surface, and the object has an object contact surface, and the cover layer contact surface and the object contact surface face each other. At least one of the cover layer and the object include a joining material. The cover layer contact surface is brought into contact with the object contact surface, and a sonotrode presses the cover layer against the object and applies mechanical vibration to an outer surface of the cover layer for a time sufficient for activating the joining material. Cover layer and object are conveyed relative to the sonotrode in a continuous manner in a conveying direction throughout the steps of arranging, of bringing into contact, of pressing and of applying vibration.

Method that forms pattern on fabric member and fixes pattern on trim

A method can be used to attach a fabric member to a trim while forming a pattern in the fabric member. A trim has trim grooves formed in one side of the trim and a fabric member has a foam formed in one side of a skin material of the fabric member. A bonding member is coated to an outer surface of the foam and the fabric member is heated where the bonding member is coated. The heated fabric member is placed on the side of the trim where the trim grooves are formed. The fabric member is fixed to the trim by inserting edges of the fabric member into the trim grooves using insertion blades while pattern protrusions formed in a compression jig form a pattern by pressing the skin material of the fabric member.
