The present invention concerns a method of detecting the making or breaking of contact of a sonotrode (4) which is caused to vibrate with a frequency f and a vibration amplitude A.sub.0 with a counterpart element (5). To provide a method with which contact-making or breaking of a sonotrode with a counterpart element can be particularly quickly and inexpensively detected it is proposed according to the invention that the method has the following steps: a) recording a time configuration of the vibration amplitude A.sub.0 (1) during a first measurement time interval T, and b) determining from the time configuration of the vibration amplitude A.sub.0 (1) whether making or breaking of contact occurred within the measurement time interval T.

A band saw is includes a driving wheel and a driven wheel rotatably provided at a saw housing; an endless saw band made to run around the driving wheel and the driven wheel; and a plurality of saw band guiding devices for directing and guiding cutting edges of the saw band toward a direction of a workpiece to be cut. The saw band guiding devices are constructed to be movable in directions where one of the guiding devices gets closer to and away from another of the guiding devices, wherein each of the saw band guiding devices includes vibrating means for vibrating the saw band in a cutting direction relative to the workpiece. A pressure member holder including a plurality of pressure rollers or a pressure member for pressing a back surface of the saw band is provided in each of the saw band guiding devices.

In a device for processing flat products using a processing tool which processes the product between the tool and a counter-tool, the processing tool is supported by an ultrasonic sonotrode. The processing tool performs a processing movement together with an ultrasonic sonotrode, wherein the processing movement results in a partial separation of the flat product.

An electrode assembly, a manufacturing method, an ultrasonic cutting device, a cylindrical battery including the electrode assembly, a battery pack and a vehicle including the same are provided. In the electrode assembly, two electrodes and a separator interposed therebetween are wound about an axis, at least one of the electrodes includes an uncoated portion provided at a long side end, a winding turn region of the uncoated portion is provided at one end of the electrode assembly, the winding turn region includes a cut portion and a bent portion alternately disposed along a circumferential direction of the electrode assembly, an axial height of the cut portion is smaller than an axial height of the bent portion, the bent portion includes a plurality of uncoated portion flags, and the plurality of uncoated portion flags overlap along and axial direction to define a bending surface region.

An apparatus for cutting a portion of an immobilization cast to facilitate removal of the cast from a body part of a patient may comprise a handle structure for being held by the hand of a user, a cutting device extending from the handle for cutting the cast material, with the cutting device including a blade and a blade movement device configured to cause ultrasonic movement of the blade, and a shielding structure configured for at least partially positioning between the cast and a part of the patient's body part such that a portion of the shield extends between the blade and the body part to shield the body part from the blade.

The device, which serves for processing, particularly for cutting and diffusing at least one product, particularly a food product, includes at least one blade that is connectable via at least one coupling member and an energy converter to an ultrasound source and that is fastened to a blade holder, which is connected to a drive device that is held by a framework. According to the invention the drive device includes a plurality of actuators, which are connected each on one side via a first rotary joint to the blade holder and on another side via a second rotary joint in such a way to the framework that the blade holder is held by the actuators alone and is displaceable and optionally turnable within a volume of operation.

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.

There is provided a machining apparatus in which movement of a machining point is a little, restriction on the machining operation of an articulated robot is a little and movement of a worker for the teaching operation is a little. The machining apparatus has an articulated robot which is controlled in attitude according to a teaching operation and has a catch instrument for catching a workpiece at an arm tip thereof, and a machining unit equipped at a fixed portion located within an arm reachable zone of the articulated robot, wherein the machining unit has a working tool having a profiling portion where a machining target portion of the workpiece caught by the catch instrument of the articulated robot is pressed according to the attitude control of the articular robot, and a floating mechanism that pushes the working tool in a press direction of the workpiece.

A cutting device includes a tool drive, cutting tool having first and second connecting parts respectively connected to first and second followers, and a guiding device, that includes a first guiding unit with first and second guiding modules. The first guiding module includes 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. The guiding wheels 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. The guiding wheels are 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 guidable alternately along the periphery of the a guiding wheel.

An ultrasonic weld/seal-cut system having an ultrasonic cutting horn with a flat ultrasonic booster to provide increased stiffness to the ultrasonic cutting horn (sonotrode) and allowing for wider cutting applications while minimizing deflections of the cutting horn under force. The flat booster has a small footprint but provides high stiffness to the cutting horn. The cutting horn and booster can be a unitary piece and can be manufactured, for example, by machining a solid plate of metal into the cutting horn with integrated booster.
