The present disclosure relates to a food processing apparatus with a scanner with a scanning unit for determining properties of a food product, in particular a food bar, with at least two substantially parallel separately drivable conveyor tracks for supplying the food products to the scanner, and with a control unit for controlling the drive of the conveyor tracks. According to the disclosure, the control unit is adapted to separately control the drive of the conveyor tracks to convey at least one food product of a first conveyor track and at least one food product of a further conveyor track sequentially through a scanning area of the scanner. The disclosure further relates to a method for scanning food products.

Knife assemblies and methods therefor that are adapted to be used with a cutting apparatus capable of producing a variety of shaped food products having large amplitudes, for example, sliced, shredded, and strip-cut food products. The knife assembly includes a primary blade having a corrugated shape to produce a large-amplitude food product slice having a periodic shape, and at least one tab blade assembled with or formed from the primary blade to cut a food product slice into strips.

Improved orthodontic appliances, as well as related systems and methods, are provided. In one aspect, an orthodontic appliance can include a shell having a plurality of cavities shaped to receive a patient's teeth. The shell can include an exterior layer and an interior layer having a stiffness less than a stiffness of the exterior layer. A discontinuity can be formed in the exterior layer.

Aligners and orthodontic systems are provided. In some embodiments, an aligner includes a polymeric shell including a plurality of tooth-receiving cavities, an interior layer, and an exterior layer. The exterior layer can comprise a discontinuity formed therein. When the aligner is worn on a patient's teeth, the interior layer can interact with the discontinuity to impart one or more forces to facilitate repositioning of the patient's teeth.

Methods for fabricating layered appliances are provided. In some embodiments, a method includes generating a digital model of a polymeric shell including a plurality of tooth-receiving cavities shaped to receive and reposition a patient's teeth from a first arrangement toward a second arrangement. The polymeric shell can include an interior layer having a first stiffness, and an exterior layer having a second stiffness greater than the first stiffness. The exterior layer can include a discontinuity formed therein. The method can further include transmitting the digital model to a fabrication system configured to fabricate the polymeric shell based on the digital model.

A cutting machine is employed to cut a window blind which includes a first support stem, a second support stem, and multiple slats. The cutting machine contains: a base, a cutting mount, a rotary cutting disc, a slidable cutter, a switch unit, and a positioning mechanism. The cutting mount includes a first through hole and a second through hole. The rotary cutting disc is configured to rotatably cut the window blind from the first through hole to the second through hole. The slidable cutter is configured to slidably cut the window blind from the second through hole to the first through hole. The switch unit includes a separation portion which moves upwardly and downwardly and has a cutting plate proximate to the slidable cutter. The positioning mechanism is configured to fix the window blind based on a desired cut length of the window blind.
