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 system—e.g. over time—for continuous image improvement are also disclosed.

A packaging apparatus includes a first holding unit configured to hold a peripheral edge portion of a film on a front side; a second holding unit configured to hold the peripheral edge portion on a rear side; a lifting unit configured to press an article to be packaged to the film; a folding unit configured to fold the peripheral edge portion on the rear side into an underside of the article to be packaged; and an extruding unit configured to extrude the article to be packaged to the front side. The first holding unit moves to decrease tension of the held film after the peripheral edge portion on the rear side starts to be folded into the underside of the article to be packaged before the extruding unit starts to extrude the article to be packaged from the rear side to the front side.

A flap folding unit is provided, comprising at least one flap folding device having a disc-like member being configured to be arranged in a first position to urge passing front flaps of an associated cardboard case to fold, and in a second position to allow unfolded rear flaps of the associated cardboard case to pass the disc-like member.

An apparatus for realising a biodegradable packaging of a product for preparation of beverages includes a first feeder group and a second feeder group. The first feeder group is of a first film made of a biodegradable material, in particular a film of polylactic acid (PLA), and a first rotary carousel, configured, together with a series of work stations associated to the first carousel, to realise a pod made of PLA, containing internally thereof a product for preparation of a beverage. The second feeder group is of a second film made of a biodegradable material, in particular a film of Ecoralene, and a second rotary carousel, configured, together with a series of work stations associated to the second carousel, to realise an Ecoralene cladding of the pod to obtain a biodegradable packaging of a product for preparation of a beverage.

A cardboard box production device includes: a stocker that holds a plurality of vertically stacked folded original boxes in a cardboard box having the top and bottom thereof open; a expansion provided upstream in a conveyance direction that is substantially orthogonal to the stacking direction of the original boxes, moving one side surface of an original box away from a first side on the stocker side towards a second side, and expanding the one side surface such that openings are formed at the top and bottom; a folding-in device that folds in the bottom of an open box opened upstream in the conveyance direction; a feeding device that feeds boxes from the upstream side in the conveyance direction to the downstream side; a conveyance belt; and an adhesion device that applies an adhesive tape to the bottom of the box in the conveyance area of the conveyance belt.

A method for controlling the processing of varying shipment sets of one or more item(s) in an automated packaging system for packaging said varying shipment sets in custom-sized boxes made from cardboard blanks, said packaging system comprising a plurality of processing stations performing different operations on said shipment sets, said operations including transporting said shipments sets to and through said stations, said method comprising: acquiring information about one or more physical properties of a shipment set or the item(s) forming the shipment set, determining based on said information if the shipment set needs or allows a specific treatment in or on the transport to and through one or more of said processing stations within said packaging system, and configuring said one or more of said processing stations with instructions for said specific treatment of said shipment set.

An object is to provide an automatic filling and packaging device which enhances the efficiency of packaging work and which suppresses the occurrence of defective products to achieve satisfactory yield.

In an automatic filling and packaging device, a locating means, a pair of upper gusset nails, a pair of intermediate gusset nails, a pair of lower gusset nails, and a blade-equipped sealing device are formed into a unit as a unit main body, and the unit main body and the pusher member are formed to be able to freely move close to and apart from each other. In this way, as compared with a conventional automatic filling and packaging device, it is possible to reduce the total time in which one article to be packaged is filled into one packaging bag and then the opening end portion thereof is sealed, with the result that it is possible to enhance the efficiency of packaging work.

An apparatus for the preparation of comestible-containing sandwich products comprises a sandwich product assembly station and corresponding means for the fabrication and assembly of a sandwich product in the vertical direction. The apparatus includes an extruder nozzle, wafer trays and corresponding components for the location of wafers on opposite sides of the extruded product, an indexing wheel for receiving the assembled sandwich product, and sandwich transporting means for moving the sandwich to a wrapping assembly and from there to a discharge end, wherein all of the components of the apparatus are mounted in cantilevered fashion on a vertical support or base member. Each element is powered individually by a servo motor or actuator and controlled by a controller allowing the variability of throughput for each station.
