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.

A method of packaging easel includes attaching an easel packaging fixture to a rotatable turntable of a stretch wrapping apparatus that includes a tower and a carriage movable along the tower. An easel bundle is positioned on the easel packaging fixture. Each easel bundle includes one or more easels with a lower portion inserted into a bottom cap and an upper portion inserted into a top cap. The turntable is rotated, causing rotation of the easel packaging fixture and the easel bundle with respect to the stretch wrapping apparatus. As the easel packaging fixture rotates, a wrapping material from the carriage of the stretch wrapping apparatus wraps around the easel bundle. The carriage moves along the length of the tower to wrap a length of the easel bundle.

A delivery system generates a pick sheet containing a plurality of SKUs based upon an order. A loaded pallet is imaged to identify the SKUs on the loaded pallet, which are compared to the order prior to the loaded pallet leaving the distribution center. The loaded pallet may be imaged while being wrapped with stretch wrap. At the point of delivery, the loaded pallet may be imaged again and analyzed to compare with the pick sheet.

A device for applying top sheets on palletised loads, including at least one support for at least one palletised load, of the feeding means of top sheets (C) to be applied on the palletised loads, suitable to unwind at least one film reel (B) from which a plurality of such sheets (C) can be obtained, and at least one applicator member suitable to place, one by one, the top sheets (C) obtained from the reel (B), over the top of respective palletised loads. The applicator member includes at least one robotic arm, having at least one operating end, and at least one winding and unwinding member, associated with such operating end; the winding and unwinding member is able to wrap the sheet (C), taken from the reel (B), on a wrapping surface to take a substantially tube-shaped configuration, and then to unwind it over the top of the palletised load.

Control of a wrapping apparatus is facilitated by enabling an operator to input a load containment force requirement and/or a minimum number of layers of packaging material to be applied to a load, with a wrap control system automatically determining wrap force and other parameters required to meet user input requirements and/or parameters to minimize the expertise required of an operator and to provide more consistent and reliable wrapping of loads. In addition, a wrapping apparatus may be controlled to apply at least a minimum number of layers of packaging material to a load throughout a contiguous region thereof.

A plant for packing bottles or similar containers includes an operating unit carrying out a rapid assembly that includes a portable pack made by three straps: a first one applied on the lower half of the body of the bottles, a second one applied at the neck of the bottles, both arranged on planes perpendicular to the vertical axes of the bottles, and a third one applied loosely and perpendicularly to the other two straps and laying on a vertical plane passing through the center of gravity of the pack.

Devices and method for accurately measuring the length of film feeding into a pre-stretch carriage from a supply roll and the length of film exiting after the pre-stretch carriage in order to accurately determine the actual percentage of film stretch occurring during the wrap cycle are provided. A first idler roller mounted on the frame of a pre-stretch carriage before the pre-stretching rollers and second idler roller mounted to the frame after the pre-stretching rollers are included. Optical rotary encoders are driven directly by idler roller shafts as stretch film passes around the shafts during film application. Systems including internet of things (HOT) devices can be fitted or retro fitted to a wide variety of stretch wrapping machines.

Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector systeme.g. over timefor continuous image improvement are also disclosed.

A device and corresponding systems and methods are provided for wrapping an object resting on an object conveyor defining an object path, the object conveyor conveying the object in a forward direction along the object path, the device comprising: an orbital wrapping mechanism configured to travel in an elliptical path around the object path and to deposit a stretch wrapping material; a wrapping material conveyor configured for cooperation with the object conveyor, the wrapping material conveyor positioned beneath the object conveyor such that when the orbital wrapping mechanism travels along the elliptical path, the orbital wrapping mechanism deposits the stretch wrapping material around both at least a portion of the object and at least a portion of the wrapping material conveyor, the wrapping material conveyor having at least one bearing surface in contact with the stretch wrapping material and movable in a forward direction such that the stretch wrapping material is conveyed along with the object in the forward direction.

A wrapping machine with rotary platform for wrapping products with one band includes a base, a rotary platform defining a supporting plane and mounted on the base to rotate about a rotation axis perpendicular to the supporting plane, and supporting rollers interposed between the base and platform and distributed around the rotation axis. The machine also includes a guiding upright parallel to the rotation axis, a supporting slide movable along the guiding upright for receiving and retaining a reel of band, an intermediate disc mounted between and coupled to the base and platform to rotate about the rotation axis, the supporting rollers being mounted on the intermediate disc and in contact with the base and platform, and a transmission system for rotating the platform and intermediate disc about the rotation axis.
