Abstract
A strip of stretch-wrap material having flat, double thickness hems at opposite margins thereof is disclosed. The hemmed strip is formed on apparatus including a first roller having a width less than the width of stock material fed into the machine, whereby opposite margins of the stock material project beyond opposite ends of the roller, and a second roller for guiding the strip at an acute angle from the first roller for causing the opposite marginal portions to fold. The strip is maintained under tension by a take-up roller or other means, and guide bars are provided for further folding the marginal portions past 90.degree. angles so that they continue to be folded inwardly against the main body of the strip.
