A bundle breaker includes upstream and downstream breaking supports, platens over the breaking supports and actuators for moving the platens toward and away from the breaking supports. Each of the platens includes a plurality of air bladders each having a bottom contact surface facing one of the breaking supports. The actuators move the platens to selectively clamp a log between the bottom contact surfaces of the air bladders and the breaking supports. A third actuator shifts an input end of the downstream breaking support relative to an output end of the upstream breaking support from a first position to a second position to break a first portion of the log from a second portion of the log.

A method where a propeller is set into locomotion relative to a medium at least partially surrounding the propeller. An actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and the propeller converts its rotational movement into locomotion relative to the medium. The aspect ratio of at least one cross-section of the propeller is three or more. Also a helical or modifiedly helical propeller for converting rotational movement of the propeller into locomotion of the propeller relative to a medium at least partially surrounding the propeller, where the aspect ratio of at least one cross section of the propeller is three or more. And a method of producing a propeller, including the step of providing a plate extending along the helical axis, where the aspect ratio of at least one cross section of the plate is three or more.

A label cutter including a blade having a curved cutting edge configured and arranged to move towards a platen in order to cut a label material placed between them. The label cutter has a force applicator arranged and configured to apply a force to a portion of the blade in the direction of the platen. The label cutter includes an actuator operatively coupled to the force applicator and operable to cause the force applicator to move. The force applicator is moveable in order to, in use, apply a force to consecutive portions of the blade in the direction of the platen so as to provide a rolling engagement between the blade and the platen. A label issuing device including a label cutter is also provided.

In one embodiment, systems and methods include using an ultrasonic cutter tool to cut a seal. The system comprises an ultrasonic cutter tool disposed onto a railing system coupled to a platform, wherein the ultrasonic cutter tool is configured to translate along the railing system. The system further comprises a power source electrically coupled to the ultrasonic cutter tool, and an alignment mold disposed parallel to the railing system and offset by a distance. The system further comprises one or more roller bearing carriages coupled to the railing system, wherein each of the one or more roller bearing carriages comprises a set of roller bearings, wherein each set of roller bearings is disposed over the alignment mold, wherein each set of roller bearings is configured to translate along the alignment mold as each of the one or more roller bearing carriages translates along the railing system.

An automated pizza cutter with a blade and a pizza resting on a working surface. Horizontal, vertical and/or rotational relative movement between the blade and the pizza is effected by different embodiments. The working surface can be moved rotationally relative to the blade, and the blade may be moved horizontally and/or vertically relative to the working surface. In one embodiment, a rotatably driven table supports a pizza while a blade disposed above the table is configured to move vertically and horizontally. A programmable user interface allows operation of the cutter. After the cutting process is completed, a blade cleaner wipes the blade of debris, which eliminates cross contamination between different types of pizzas.

A stamping machine for labels and covers includes a servomotor as a driving element. The servomotor can be directly or indirectly connected to a spindle which causes the stamp to move forward in a linear manner.

A cutting device includes an upper cutting portion and a lower cutting portion. The upper cutting portion includes an upper head portion movable in a first and a second direction, an upper holder connected to the upper head portion, and an upper cutting wheel connected to the upper holder. The upper holder includes an upper body portion connected to the upper head portion, an upper cutting wheel fixing portion rotatable with respect to the upper body portion, and an upper magnetic portion disposed on sides of the upper cutting wheel fixing portion including a magnetic substance. The lower cutting portion includes a lower head portion movable in the first and the second direction, a lower holder connected to the lower head portion, a lower cutting wheel connected to the lower holder, and an upper holder rotation inducing portion connected to the lower head portion including a magnetic substance.

A cutting device and a method for cutting paper are provided. The cutting device includes a cutting blade and a counter-member. The cutting device is further provided with a first guide and a second guide extending in or parallel to the driving direction for linearly guiding a holder that holds the cutting blade. Each of the guides includes a guide body. The guide bodies of the first guide and the second guide, when released, are arranged to be rotatable relative to the frame about a first adjustment axis and a second adjustment axis, respectively. Each guide body includes an eccentric section that moves eccentrically about the respective adjustment axis and that is arranged to convert the rotational movement of the guides about the respective adjustment axes into a linear movement of the holder in the adjustment direction.

The invention relates to an apparatus comprising a separating tool and comprising a counterpressure plate for producing contour geometries in adhesive-containing composite materials, wherein the separating tool can be moved in translational tool stroke directions between an inoperative position and a parting position normal to the counterpressure plate, and also to a method for producing contour geometries in adhesive-containing composite materials by means of an apparatus of this kind. The separating tool and the counterpressure plate can be actuated relative to one another by means of at least one actuator in at least one excitation direction with a ramp function and/or with a jump function. Each of these excitation directions lies in a parallel plane to a cutting edge plane of the separating tool. The present invention permits reliable separation of a stamped grid from laminate sections which remain on a carrier film.
