Patent number: 11717995Abstract: An automated manufacturing method and system and in-mold coated plastic article produced thereby are provided. The system includes a compression mold and a plurality of program-controlled manipulators. An automatic sprayer supported on a first manipulator sprays at least a portion of a mold surface with an in-mold coating composition. An end effector supported on a second manipulator picks up a heated blank of moldable plastic sheet material from an oven and places the heated blank between upper and lower mold halves of the mold. An inner portion of the heated blank is forced into an article-defining cavity of the mold and into contact with at least a portion of the in-mold coating composition. The in-mold coating composition and the inner portion of the heated blank cure and bond to one another so as to form the coated plastic article.Type: GrantFiled: March 21, 2022Date of Patent: August 8, 2023Assignee: Global IP Holdings, LLCInventors: Christopher A.

Patent number: 10723168Abstract: Embodiments of the present invention provide a stair layout template that reduces the opportunity for errors when constructing a set of stairs. Embodiments also provide a method for using the template to construct a set of stairs. The template indicates to the builder where a particular set of marks are to be made on the insides (the sides where the tread modules are attached) of both stringers. These marks include the cut marks for the bottom and top ends of the stringers and the “screw set points” that indicate where the tread modules will be attached to the stringers. The template is reversible, with the mirrored markings on both sides, so that the process for one stringer is the mirror image of the other stringer.Type: GrantFiled: January 25, 2018Date of Patent: July 28, 2020Inventors: Steven A. Mitchell, Paul E. Sanders, Jonathan D. Mitchell

Patent number: 10618203Abstract: A method of making a trimmed, laminated trim component is provided. A heated plastic composite sheet is pressed against a heated laminated sheet to bond a plastic cushioning layer of the laminated sheet to the plastic composite sheet. The step of pressing compresses a portion of the laminated sheet spaced inwardly from an outer periphery of the laminated sheet to locally compact and thin the cushioning layer at the portion to form a compressed portion of the cushioning layer. Unwanted portions of the laminated sheet are trimmed.Type: GrantFiled: July 20, 2015Date of Patent: April 14, 2020Assignee: Global IP Holdings, LLCInventors: Darius J Preisler, Christopher A.

Publication number: 20190389102Abstract: A method of making a trim component having an edge-wrapped, fibrous decorative covering is provided. A fibrous decorative covering overlies and is in contact with an outer surface of a composite sheet. The composite sheet is pressed against an interior portion of the covering to bond the interior portion to the composite sheet while maintaining at least one exterior edge portion of the covering unbonded to the composite sheet. A molten polymer compatible with the polymeric material of the composite sheet is injected in accordance with a predetermined set of process parameters which are high enough to integrally form at least one structural component via polymeric interfusion at the inner surface of the composite sheet but low enough to avoid damaging the covering. The at least one unbonded, exterior edge portion is folded over the composite sheet to form the trim component.Type: ApplicationFiled: June 21, 2018Publication date: December 26, 2019Applicant: Global IP Holdings, LLCInventors: Christopher A.
