Problems solved by technology

[0008] Unlike cardboard, plastic foam packaging can be made on demand on demand, but the process is very slow (its speed is typically about 9 meters per minute, compared with about 20 meters per minute for some converters that make paper dunnage comparison), and its speed is limited by the nature of the foam pack being made
Plus, plastic is increasingly expensive and increasingly seen as harmful to the environment

Embodiment Construction

[0068] The present invention provides a dunnage conversion machine and method for forming sheet stock material into packable dunnage products, as well as a stock supply assembly and output chute for the dunnage conversion machine and corresponding method.

[0069] Packable dunnage

[0070] The present invention provides a packable dunnage product, a dunnage converter for converting a sheet stock material into a packable dunnage product, and a packable dunnage product for making a packable dunnage product that is relatively thicker and looser than the stock material. The corresponding method for the litter product. In particular, the present invention provides a multi-ply dunnage product having sufficient flexibility and thickness to be used as a protective layer or wrap. At least one ply of the dunnage product comprises a randomly creased web or sheet. Randomly creasing at least one sheet provides cushioning properties to the dunnage package. The crumpled sheet or sheets ar...

Abstract

A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

Description

[0001] This application claims U.S. Provisional Patent Application 60 / 974,532, filed September 24, 2007, U.S. Provisional Patent Application 61 / 035,701, filed March 11, 2008, and U.S. Provisional Patent Application 61 / 076,365, these provisional patent applications are hereby incorporated by reference. technical field [0002] The present invention relates to a dunnage conversion machine, and more particularly to a stock supply assembly and output chute for a dunnage conversion machine and a corresponding method, and to a method for converting sheet stock material into packable dunnage products A dunnage conversion machine and method thereof. Background technique [0003] Dunnage conversion machines are used to convert raw materials into dunnage products that can be used to package items and thereby minimize or prevent damage to the items during shipment. A dunnage conversion machine (also referred to as a dunnage converter) includes a conversion assembly that converts raw ...
