Cushioning conversion machine and method

摘要

A cushioning conversion machine (20) comprising a conversion assembly (30) which converts a sheet-like stock material (22) into a three dimensional cushioning product (32) and a stock supply assembly (550) which supplies the stock material (22) to the conversion assembly (30);
the conversion assembly (30) including a forming assembly (52) which inwardly turns lateral regions of the stock material (22) as the stock material travels therethrough in a downstream direction;
the stock supply assembly (550) including a stock-dispensing device (570) which dispenses the multi-ply stock material (22) from a continuous sheet thereof and a constant-entry device (580) which determines an entry point of the stock material (22) upstream of the conversion assembly (30);
the constant-entry device (580) also temporarily functioning as a force dampening device during a high-tension situation and then automatically returning to its normal operating position once the high tension situation is resolved.
