Abstract:
A system and method for arrow fletching by bonding vanes to a vinyl wrap allows for efficient, accurate fletching of arrows. The vanes are placed into a number of slits positioned on a jig plate. The jig plate in a holder is placed into a heat press, thereby bonding the vanes to the vinyl wrapping and creating a fletched arrow wrap. Once the fletched arrow wraps are cooled they are placed in a fletching jig, with an adhesive coating on the backside of the wrap exposed by removing a paper backing. The shaft of each arrow is rolled over the adhesive coating such that the wrap becomes affixed to the shaft of the arrow, thereby fletching the shaft.
Abstract:
A rotary die system that includes first and second axially aligned, coacting rotary dies positioned adjacent one another. Each die includes a working surface having a plurality of recesses defined therein. The recesses in the first die are each configured to align with a recess in the second die to form a product cavity upon coaction of the first and second dies. The product cavity is configured to receive a product. Each recess in at least one of the first or second dies includes a pin therein that is configured to puncture a film that at least partially surrounds the product.

The disclosure provides a hollow foam duct with an insert for improved connectability. The insert provides tactile and/or audible feedback to a user connecting a foam duct to, for example, an HVAC unit in an automobile. A method for making a foam duct is also disclosed.
Abstract:
A dunnage platform is in the general shape of a rectangular slab with legs extending form one side. The dunnage platform is made from an expanded polystyrene core. A chemical combination process is used to chemically combine portion of the core proximal to its surface with high impact polystyrene. In a first of two parts of the combination process, the core is placed in a forming mold with one of its two sides and two thirds of its thickness extending therefrom. A heated sheet of high impact polystyrene is brought into contact with the portion of the core extending from the mold. In a similar manner, the other of the two sides of the core is made to extend from the forming mold for contact with a heated sheet of high impact polystyrene.
Abstract:
High-efficiency thermal insulation products and methods for use thereof for insulating cylindrically-shaped and other non-planar objects such as pipes, tanks, and the like. One method includes heating a substantially gas-tight enclosure to render the gas-tight enclosure pliable, wrapping the inner surface of the gas-tight enclosure about at least a portion of a non-planar surface, and cooling the gas-tight enclosure to render the gas-tight enclosure substantially unpliable about the non-planar surface. The gas-tight enclosure may include a sealed interior portion having a pressure that is not greater than about 500 mbar at a temperature of about 20° C. before the heating step and/or after the cooling step. A ratio of a thickness of the gas-tight enclosure to a radius of curvature of the portion of the non-planar surface may be at least about 1 to 8.

Disclosed herein are a printed circuit board and a method of manufacturing the same. According to an exemplary embodiment of the present invention, the printed circuit board includes: a first insulating layer in which a metal layer is embedded; a warpage prevention layer stacked on the first insulating layer; second insulating layers stacked on both surfaces of the first insulating layer; a via formed on the second insulating layer to be connected to the metal layer; and a solder resist layer stacked on the second insulating layer.
Abstract:
A method for creating a vacuum setup for processing a semi-finished fiber composite into a cured fiber composite component is provided. The semi-finished fiber composite is positioned on a molding surface of a tool so that a non-planar surface of the semi-finished fiber composite faces away from the molding surface, covering the non-planar surface of the semi-finished fiber composite by applying an air-tight film and sealing the film with respect to the molding surface of the tool. Application of the film is performed using a plunger formed from a flexible material and having a plunger surface on which the film is retained.
Abstract:
Methods and apparatus are for decorating bowling balls. A spherical bowling ball inner core has opposing first and second hemispheres. Pressure is applied to adhere a first portion of a conformable decorative first film of material onto the first hemisphere. A combination of pressure and vacuum is applied to adhere a second portion of the first film of material onto the first hemisphere. Pressure is applied to adhere a first portion of a conformable decorative second film of material onto the second hemisphere. A combination of pressure and vacuum is applied to adhere a second portion of the second film of material onto the second hemisphere. Thereafter the bowling ball inner core is covered with a transparent outer cover.
Abstract:
Feedstock is delivered perpendicular to the line of applied glue in an automated gluing machine, thereby simplifying operation and better accommodating other in-line factory or assembly processes. The machine comprises an input nip for receiving the head end and the tail end of a sheet stock in overlapping registration, with the tail end being longer than the head end. A clamp mechanism holds the overlapping sheet stock in position while a glue applicator applies glue to one side of the tail end. An output nip holds the glued side of the tail end against the head end, and apparatus is provided for ejecting the sheet stock once the tail end has been glued to the head end. The glued stock may be ejected back toward the operator or away from the operator and through the machine, enabling the machine to be placed in-line with other machines for a continuous directional or linear flow.
