The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).

A system for cutting a three-dimensional portion from a foodstuff includes a conveyor for carrying a foodstuff to be portioned, a scanner located adjacent to the conveyor for scanning the foodstuff, a computer coupled to the scanner for receiving scan information to determine one or more cutting paths for the foodstuff, and a cutter for portioning the foodstuff according to the determined cutting path(s). The computer performs generally four steps: (i) receiving scan information from the scanner; (ii) building a three-dimensional map of the foodstuff based on the received scan information; (iii) fitting at least one desired shape, which is stored in the memory of the computer, onto the built three-dimensional map; and (iv) determining one or more cutting paths for portioning the foodstuff to produce one or more portioned foodstuffs corresponding to the at least one desired shape.

Proposed is an ultrasonic bread cutter, in which high-frequency electrical energy is converted into mechanical energy by an ultrasonic unit and bread is cut by ultrasonic vibration of a cutting knife. The ultrasonic bread cutter according to an embodiment includes the ultrasonic unit configured to convert high-frequency electrical energy into the mechanical energy; and the cutting knife configured to cut bread by transmitting the mechanical vibration of the mechanical energy to the bread while passing through the bread.

The handpiece-type high-frequency vibration apparatus includes a roughly cylindrical housing 10 configuring a handpiece, a holding member 11, a tool 12, a controller 20 and an excitation device 21. In a non-contact state before the tool 12 is brought into contact with an object, the controller 20 drives the excitation device 21 so as to vibrate the tool 12 at an added frequency fp for which a predetermined frequency fs is added to a first resonance frequency fr1 of the tool 12. In a cutting state where the tool 12 is in contact with the object by a load that enables cutting of the object by the tool 12, the controller 20 controls drive of the excitation device 21 such that a third resonance frequency fr3 of the tool 12 increases and coincides with the added frequency fp, and increases a vibration frequency of the tool 12.

A tool for pressing a foamed material onto a substrate, a manufacturing apparatus thereof, and a method for manufacturing a laminated structure of a heat-retaining container are disclosed. The tool comprises a body, a blade portion extending in a lengthwise direction from the body, and a press portion extending in the lengthwise direction from the body and configured for pressing the foamed material onto the substrate. The tool may be used to press a foamed material sheet onto a paper substrate and form a tear line on the foamed material sheet at the same time to simplify the manufacturing process of the laminated structure of a heat-retaining container.

A manufacturing method of a multilayer syringe barrel is provided and includes: a finish cutting a remaining gate of a nozzle portion of a multilayer syringe barrel that is injection-molded from a nozzle tip, with a cutting blade of an ultrasonic cutting apparatus including a mechanism for suppressing abnormal vibration; and irradiating a laser beam to a corner portion of the nozzle portion, the corner portion being formed during the finish cutting.

The technology as disclosed herein includes a method and apparatus for deboning a meat item, and more particular for deboning a poultry item including performing an initial shoulder cut for removing boneless breast meat from the poultry carcass or frame. The method and apparatus disclosed and claimed herein is a combination of a robotic arm including an ultrasonic knife implement and a vision system for varying the cut path based on the shape and size of the poultry item. The combination as claimed including the ultrasonic knife can perform a meat cut while penetrating the meat with less force than the typical penetration that occurs when using a traditional knife.

An ultrasonic vibration assisted machining device is applied to a cutting tool and includes a vibrating component and a spinning component. The vibrating component includes a main body including a first end surface, a second end surface and a central axis. The vibrating component is configured to receive electrical power and generate a vibration with a vibrating frequency in the central axis direction according to the electrical power. The spinning component includes a first surface connected to the second end surface of the vibrating component. The area of the first surface is greater than that of the second end surface. The spinning component generates a spinning motion centered on the central axis according to the vibration with the vibrating frequency generated by the vibrating component. Wherein, the spinning component transmits the vibration and the spinning motion to the cutting tool.

A multifunctional shaft apparatus includes a shaft base, a spindle, a tool holder, an ultrasonic vibration assembly, a laser light source and a mirror assembly. The spindle is disposed in the shaft base. The spindle has a laser channel extending along the spindle. The tool holder is disposed on the spindle. The tool holder has a hollow passage, an inner space and a recessed portion. The hollow passage is communicated with the laser channel. An inner wall of the hollow passage has at least one through hole communicated with the inner space, and the recessed portion is disposed on a bottom surface of the tool holder. The bottom surface has a light outlet. The ultrasonic vibration assembly includes a vibration member disposed in the recessed portion. The mirror assembly is disposed in the tool holder and is configured to reflect the laser light beam generated by the laser light source.

This disclosure relates to apparatuses and methods for processing and grading food articles. For example, provided herein is a system for grading a portioned food article, in which the system includes: a first conveyor; a first receiving conveyor and a second receiving conveyor, defining a space therebetween; at least one spray-removal robot; and a third receiving conveyor. The spray-removal robot may include at least one valve with a nozzle, in which the valve ejects fluid through the nozzle to impact a food article being moved on the first conveyor toward the third receiving conveyor, such that at least one portion of the food article is moved by the impact through the space between the first receiving conveyor and the second receiving conveyor, and such that at least one portion of the food article is moved by the first receiving conveyor and the second receiving conveyor to the third receiving conveyor.
