Patent number: 10227152Abstract: A method, apparatus and program product monitor a wrap force during a wrap cycle to dynamically control the dispense rate of a packaging material dispenser to meet a desired containment force to be applied to a load. A conversion may be performed between wrap force and containment force for the monitored wrap force or a containment force parameter to facilitate the performance of a comparison between the monitored wrap force and a containment force parameter associated with the desired containment force to be applied to the load. A wrap force parameter may also be dynamically adjusted, and in some instances, the dynamic adjustment may be responsive to monitored wrap force, and may be used to meet a load containment force requirement for a load. In other instances, the dynamic adjustment may be responsive to monitored packaging material breaks to reduce the occurrence of packaging material breaks.Type: GrantFiled: January 14, 2015Date of Patent: March 12, 2019Assignee: Lantech.com, LLCInventors: Patrick R.

Patent number: 10053253Abstract: A method, apparatus and program product utilize a graphical interface to facilitate operator interaction with a load wrapping apparatus, particularly in connection with setting up a wrap profile. The graphical interface may incorporate a graphical depiction of a load, along with graphical depictions of both the number of layers of packaging material and the wrap force associated with a given wrap profile, with the graphical depictions of each of the number of layers of packaging material and the wrap force being capable of being dynamically updated in response to changes made by an operator to a wrap profile. The graphical depictions therefore provide a visual interface to assist an operator who may have limited expertise in setting up a load wrapping apparatus.Type: GrantFiled: October 7, 2015Date of Patent: August 21, 2018Assignee: Lantech.com, LLCInventors: Patrick R.

Patent number: 10005580Abstract: A wrapping apparatus and method utilize a corner rotation angle-based wrap control that controls the rate at which packaging material is dispensed based on the rotational position of one or more corners of the load during relative rotation established between the load and a packaging material dispenser.
