Abstract: There is provided a film dispenser including a pre-stretch assembly, a dancer bar and a dancer bar control assembly. In response to a variation of a film feed requirement, the dancer bar is movable over a displacement range between a first position and at least one second position. The dancer bar is in the first position when a tension in the material web is below a threshold and in the at least one second position when the tension in the material web is equal to or above the threshold. The dancer bar control assembly is connected to the pre-stretch assembly and the dancer bar and is configured to bias the dancer bar with a constant force over the displacement range, monitor a displacement of the dancer bar and generate a speed command based thereon, and send the speed command to a motor to adjust the film delivery speed.

Abstract: There is provided a method for wrapping a load comprising an upper portion defining an upper peripheral surface and a lower portion defining a lower peripheral surface. The method includes configuring a first material dispenser including a first material web in a first starting position and a second material dispenser including a second material web in a second starting position. The method includes and providing a rotation between the load and the material dispensers, such that, upon the rotation, the first material dispenser wraps the upper peripheral surface of the load with the first material web and the second material dispenser wraps the lower peripheral surface of the load with the second material web. The first material dispenser wraps the upper peripheral surface of the load simultaneously while the second material dispenser wraps the lower peripheral surface of the load during at least a portion of a wrapping cycle.

Abstract: A wrapping apparatus, its components, and corresponding methods for wrapping a load in packaging material are described herein. The apparatus has a packaging material dispenser having a frame and a plurality of packaging material supplies. The apparatus also has a load press for wrapping an upper surface of the load, where the load press has a central press section and a peripheral press section which can disengage the upper surface to allow wrapping of at least a part thereof. The apparatus also has an enclosure to prevent access during operation, as well as a packaging material seeking assembly which seeks out the packaging material to be wrapped. The apparatus and methods described allow for an automatic wrapping of a load which minimizes operator intervention, and further allow for the automatic resupply of packaging material.

Abstract: The method and apparatus are for making a knot with first and second rope-shaped end portions of flexible material wrapped around an article. The method comprises steps of (a) guiding the end portions along a predetermined path; (b) (i) nipping the first end portion at a first point of the predetermined path, (ii) nipping the second end portion at a second point of the predetermined path, and (iii) nipping the second end portion at a third point of the predetermined path; (c) cutting the second end portion between the second and third points to obtain a free end thereof; (d) moving the end portions to obtain a loop; (e) releasing the first end portion from the guiding of step (a) to obtain a free end thereof; and (f) inserting the free ends into the loop to form and tighten the knot.

Abstract: Apparatus and method for handling and cutting a flexible material that is wrapped around a load by means of a delivering device. The apparatus includes a clamp and cutter assembly having a trigger activated mechanism, and a trigger and roping assembly. The apparatus also includes a moving device for moving the trigger and roping assembly between active and retracted positions. In use, as the trigger and roping assembly is moved into its active position, the trigger engages with the trigger activated mechanism to move the clamp and cutter assembly to its open position, while the roper turns a portion of flexible material into a rope. As the trigger and roping assembly is retracted from its active position, the trigger disengages with the trigger activated mechanism to move the clamp and the cutter assembly in its closed position, thereby cutting the rope and holding a free end thereof.
