Abstract
Stretch wrapping packaging material on a load includes introducing stretch wrap packaging material onto V shaped tips of projecting portions of a first grooved roller so that the packaging material spans the nonprojecting portions of the first grooved roller. The web of packaging material and the first grooved roller are transported in the direction generally parallel to the grooves. The web of packaging material spanning the nonprojecting portions of the first grooved roller is impinged with V shaped tips of projecting portions of a second grooved roller. The tips of the projecting portions of the second grooved roller are transported at a speed which is less than the speed of the tips of the projecting portions of the first grooved roller.
The tips of the projecting portions of the second grooved roller moves at a speed which stretches the web between the first and second grooved surfaces in a direction transverse to the direction in which it is transported and minimizes any stretching of the web in the direction in which the web is transported. The web is stretched between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the web is transported. The web is separated from the first and second grooved surfaces and wrapped onto a load by providing relative rotation between the load and a dispensing mechanism for the web.
The tips of the projecting portions of the second grooved roller moves at a speed which stretches the web between the first and second grooved surfaces in a direction transverse to the direction in which it is transported and minimizes any stretching of the web in the direction in which the web is transported. The web is stretched between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the web is transported. The web is separated from the first and second grooved surfaces and wrapped onto a load by providing relative rotation between the load and a dispensing mechanism for the web.
