    Abstract: A leading end of packaging material is grasped in a packaging material holder while a load is wrapped. Packaging material is dispensed from a packaging material dispenser, and relative rotation is provided between the dispenser and a load to wrap packaging material around the load. The packaging material holder may be positioned on the rotating surface of a turntable but isolated from any electrical or fluid power source of a rotatable surface of the turntable. During the wrapping cycle, the packaging material holder moves downstream along the turntable, automatically releasing the leading end of the packaging material and automatically grasping a trailing end of the packaging material. The packaging material is weakened and then severed between the packaging material holder and the load. The packaging material holder is mounted to permit it to move upstream due to force exerted by the packaging material held in the holder.

    Abstract: The present invention relates to an apparatus and method for stretch wrapping a load in an efficient manner so as to tightly and securely wrap the load at a desired tension without rupturing the packaging material. The method and apparatus compensate for variation in demand rate as the load is wrapped so as to apply the wrapping material to a load at a desired force, maintain the desired containment tension on the wrapping material on the load after wrapping, and prevent the wrapping material from rupturing during wrapping. The apparatus combines two systems, power assisted roller stretch (“PRS”) and roller stretch (“RS”) to vary the supply rate of the packaging material as the demand rate varies. The apparatus automatically switches between the two types of prestretch to achieve “high” and “low” wrapping force dependent upon the demand rate. Changes in the demand rate are sensed by monitoring changes in the payoff angle of the packaging material extending between the dispenser and the load.

    Abstract: A load portion is engaged in an infeed area and transported from the infeed area to a wrapping area with rotational, horizontal, and vertical carriers. Those carriers move the portion of the load horizontally along two horizontal degrees of freedom and one vertical degree of freedom by rotating a portion of the load about a vertical axis and translating the portion of the load along a generally linear horizontal direction and a generally linear vertical direction. The load is disengaged in the wrapping area and a stretch wrap packaging material dispenser is engaged and is transported to the wrapping area by the same rotational, horizontal, and vertical carriers to wrap the portion of the load with stretch wrap packaging material by using, once again, the same rotational, horizontal, and vertical carriers to rotate the dispenser around the load.

    Abstract: Stretch wrapping packaging material on a load includes introducing such wrapped packaging material onto tips of projecting portions of the first grooved rollers so that the packaging material spans the nonprojecting portions of the first grooved roller. The web of the packaging material on the first grooved roller are transported in the direction generally parallel to the grooves by powering the first grooved roller. The web of the packaging material spanning the nonprojecting portions of the first grooved roller is impinged by the tips of the projecting portions of an idling second grooved roller to stretch the sheet between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the sheet is transported. The web is preferably separated from second grooved surface either before or simultaneous with its separation from the first grooved roller.

    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.

    Abstract: An apparatus and method for wrapping a top and bottom of a load with packaging material is provided. The apparatus includes at least one non-driven packaging material guide is provided for use in combination with a powered conveying surface. The non-powered packaging material guide includes at least one row of non-driven wheels attached to a rail. The force applied by the packaging material as it is wrapped around the guide is supported by both the rail and the at least one row of non-driven wheels. The rail also serves to bridge any gaps between the non-driven wheels, thereby preventing capture of packaging material between the non-driven wheels. Preferably, the packaging material guide includes two rows of non-driven wheels, one on each side of the rail. Further, it is preferable that the rail connect the two rows of wheels such that the two rows of wheels form an angle of 60 degrees between them. The packaging material guide is preferably positioned above the load but may also be positioned either below the load or to the sides of the load.
