Abstract
A cushioning conversion machine for converting stock material into a continuous strip of a cushioning product. The machine includes a stock-preparing assembly which prepares the stock material; a stock-shaping assembly which shapes the prepared stock material into a continuous strip having a pillow-like portion and at least one tab portion projecting therefrom; and a tab-connecting assembly which connects the tab portion of the continuous strip whereby the pillow-like portion will maintain its pillow-like geometry.
Claims11
A method for producing a cushioning product, said method comprising the steps of providing a multilayer stock material, and converting the multilayer stock material into a strip of dunnage;
- wherein the converting step includes feeding the stock material through a shaping member having converging sidewalls so as to cause the layers of stock material to be folded on itself to form a relatively narrow cushioning strip, feeding the folded portion of the narrow cushioning strip through a pair of cooperating rollers which engage the narrow cushioning strip, one of the rollers having a central annular recess on its periphery and the other having a central annular raised portion on its periphery projecting into the recess in the other roller to form a generally U-shaped passage between the rollers for the narrow cushioning strip.
