Either the gripping device including a hold-down section placeable for cutting purposes onto the material web positioned on the blade table and fixes the material web during the cutting on the blade table, and a magnetic element which interacts magnetically with the magnetically couplable element of the cut strip for fixing the strip on the gripping device for transport into a dispensing position, and the hold-down section including a recess, through which the cutting blade can be moved to the blade table into the cutting position, or the gripping device including a hold-down section placeable for cutting purposes onto the material web which is positioned on the blade table and fixes the material web during the cutting on the blade table, and a magnetic element which interacts magnetically with the magnetically couplable element of the cut strip for fixing the strip on the gripping device for transport into a dispensing position, and at least one further hold-down element being provided which can be placed onto the material web for cutting purposes spaced apart from the hold-down section with the configuration of a clearance, it being possible for the cutting blade to be moved through the clearance to the blade table into the cutting position.

A system and method for vibratory cutting, including in the manufacture of ceramic honeycomb bodies. The apparatus includes a transducer configured to generate vibrations with respect to an axial direction. A cutting element is configured to receive and oscillate axially in response to the vibrations. The cutting element has a blade having a width, an axial length, and a thickness. A cutting plane of the blade is defined with respect to the width and the axial length. The blade has opposing side surfaces that extend parallel to the cutting plane. The thickness extends perpendicular to the cutting plane between the opposing side surfaces. A set of fluid bearings are configured to exert fluid pressure on each of the opposing side surfaces to constrain vibrations of the blade oriented in directions transverse to the cutting plane.

A system and method for shaped cutting of washable sanitary absorbent articles having a back layer of washable fabric and the like is provided, wherein the back layer is fed longitudinally along a travel direction to a cutting unit including at least one cutting tool movable transversally to the travel direction so as to cut at least one longitudinal side edge of the back layer, in combination with a longitudinal displacement thereof, along a curved profile.

A cutting device includes a tool drive, cutting tool having first and second connecting parts respectively connected to first and second followers, and guiding device, including a first guiding unit with first and second guiding modules. The first guiding module includes first and second guiding wheels, which are held each by related bearing devices rotatable in a guiding plane, peripherally adjacent to each other at a first transfer position, include an outwardly open receiving opening suitable for receiving the first follower, rotatable by the tool drive in opposite directions with the same angular velocity, and arranged so that their receiving openings lie opposite one another at the first transfer position after each revolution, so that the first follower is transferable alternately from one receiving opening into the other at the first transfer position and is further guidable alternately along the periphery of the first or second guiding wheel.

An ultrasonic cutting tool for use in an ultrasonic instrument, the tool being a blade manufactured from a tubular blank by flattening a section of the blank. The blade includes a flat section designed to be used for cutting, a tubular section, and a transition section joining the flat section to the tubular section. The tubular section is joined to or includes an attachment section for attaching the blade to an ultrasonic generator and serving as a conduit to bring a cooling fluid to the distal end or to suck particles into the hand tool.

A parting device and a parting method are provided, in particular for trimming workpieces (2), in particular solar modules. The parting device has a multi-member (12, 13, 14, 15) programmable robot (6) which is in the form of a tactile robot, in particular a force/torque-regulated robot. The robot guides a parting tool (8) which is in the form of a knife.

The present disclosure describes an ultrasonic rotary molding system that is used to form edible compositions or food products as they move along a conveyor belt. The food products are formed by an ultrasonic rotary wheel that includes one or more cutting tools that cut, and perhaps three dimensionally mold, food product strips. The system may include a movable backing plate that is located below the point where the ultrasonic rotary wheel cuts the food product strips. The movable backing plate may be spring loaded and it may exert force upwards against the conveyor belt and in turn against the food product.
