An apparatus for wrapping a load may include a film dispenser for dispensing a film web including a film dispensing drive. The apparatus may also include a rotational drive system for providing relative rotation between the load and the dispenser during a wrapping cycle. The apparatus may further include a controller configured to operatively couple the film dispensing drive and the rotational drive system such that, for any portion of a revolution of the film dispenser relative to the load during the wrapping cycle, the film dispenser dispenses a selected length of the film web corresponding to the portion of the revolution.

Electronic control of metered film dispensing in a wrapping apparatus

A method, apparatus and program product are provided that utilize wrap profiles that specify controlled wrap cycle interruptions to handle specialized load requirements for loads to be wrapped by a stretch wrapping machine. Also provided is a method of creating wrap profiles, and a plurality of wrap profiles are stored in a database.

Load wrapping apparatus wrap profiles with controlled wrap cycle interruptions

A method, apparatus and program product utilize a torque control algorithm constrained by a speed window to control the dispense rate of a packaging material dispenser when wrapping a non-cylindrical load with packaging material. In particular, a dispenser motor of the packaging material dispenser that is controlled by a VFD may be driven to maintain a substantially constant torque, while also constrained to operate within a speed window that is based at least in part on a rate of relative rotation between the packaging material dispenser and the load.

Stretch wrapping machine with variable frequency drive torque control

A control system for a wrapping apparatus may include a packaging material dispenser configured to dispense packaging material for wrapping a load. The control system may also include at least one sensor assembly configured to generate a signal based on instantaneous demand for packaging material at the load. The control system may further include a controller configured to control operation of the packaging material dispenser based at least in part on the signal.

Demand based wrapping

A method for generating data with a wrapping machine during wrapping of a load includes measuring a length of packaging material dispensed during wrapping of the load with a sensing assembly on the wrapping machine. The method further includes obtaining a value indicative of a weight of the packaging material per unit of length and determining a weight of the packaging material dispensed on the wrapped load based on the measured length and the obtained value without removing the packaging material from the load. The determined weight of the packaging material is displayed on a display device.

Machine generated wrap data

Various methods are provided for determining and displaying wrapping data generated by a wrapping machine during wrapping of a load with a packaging material, e.g., to determine numbers of layers of packaging material applied to a load, a containment force applied to a load, and/or whether a load meets a predetermined minimum required containment force standard for the load.

A load having top and bottom caps is stretch wrapped at a wrapping station having turntable and a dispenser for dispensing stretch wrap packaging material, and a corner board placer for placing a corner board having tapered top and bottom edges on each corner of the load. With the load positioned on the turntable, the corner board placer is controlled by a controller to perform the steps of forming an acute angle between first and second portions of the corner board, and moving the corner board toward the corner until the first and second portions have been inserted between the top and bottom caps. The controller then causes the corner board placer to perform the steps of opening the corner board to substantially form a right angle, and simultaneously placing the first and second portions of the corner board proximate respective sides of the load by moving the corner board toward the corner in a direction oblique to the respective sides while maintaining the first and second portions generally parallel with the respective sides. A restrainer is provided for holding each corner board in place to allow subsequent corner board placement on another corner of the load. The turntable is rotated to wrap the load with the corner board placed on the corners of the load.
