Abstract

A molded fiber part production line includes a forming station, a part transfer system, a press station, and a removal system. The forming station includes a slurry tank, a forming mold, and a mold actuation system. The part transfer system includes a part transfer feature and a conveyance mechanism. The press station includes a core mold, a cavity mold compatible with the core mold, and a press actuation system. The removal system includes a removal feature defining a plurality of part vacuum channels and a plurality of trim vacuum channels. The removal system also includes a conveyance mechanism for moving the removal feature from a position in engagement with at least one of the core mold and the cavity mold to another position.

Description

[0001] Cross References to Related Applications [0002] This application was filed as a PCT International Patent Application on May 6, 2020 and claims U.S. Provisional Patent Application Serial No. 62 / 844,044 entitled "IMPROVED PRODUCTION LINE FOR PRODUCTING MOLDED FIBER PRODUCTS," filed May 6, 2019 priority, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Pollution from single-use plastic containers and packaging materials is now a recognized worldwide problem. Replacing single-use packaging with biodegradable and compostable materials is recommended as a way to reduce plastic pollution. However, for a new environmentally friendly alternative to be successful, it must be cost- and performance-competitive with the existing plastic technology it replaces. [0004] As a brief background, molded pulp (also known as molded fiber) has been used since the 1930s to make containers, trays, and other packaging. Pulp can be ...
