ABSTRACT:
Successive layers of stretch film are wrapped around a load stacked on a motor driven rotatable turntable, the film being supplied as the leading end of a web pulled off a rotatable non-driven roll, and rotation of the roll being initially positively restricted by a spring biased brake. Tension in the web is successively increased to automatically increase stretch in the web in stages during succeeding revolutions. An anchoring member is automatically projected to hold the pallet immovable on the table during wrapping.
