The cutting machine includes at least one feed path for elongated products, wherein the elongated products move forward along a direction substantially parallel to the longitudinal extension thereof. The cutting machine includes a rotating unit adapted to rotate around a rotation axis, carrying at least one first disc-shaped cutting blade and one second disc-shaped cutting blade. The rotation of the rotating unit causes an orbital movement of the first disc-shaped cutting blade and of the second disc-shaped cutting blade along trajectories intersecting the product feed path. The first disc-shaped cutting blade and the second disc-shaped cutting blade are offset from each other in a direction parallel to the product feed path. The first disc-shaped cutting blade and the second disc-shaped cutting blade are also angularly offset from each other with respect to the rotation axis of the rotating unit.

A cutting machine head and a cutting machine are provided in the present invention. The cutting machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. The cutter holder is mounted on the fixing plate. The machine head lifting mechanism is connected to the cutter holder, and is used to drive the cutter holder to move up and down on the fixing plate. The cutting component includes at least two cutter head assemblies mounted on the cutter holder. The machine head rotating mechanism is connected to the cutter head assemblies for driving the cutter head assemblies to rotate. The rotating angle of each cutter head assembly of the cutting machine head can be controlled. The machine head rotating mechanism controls the cutter head assembly to rotate when the machine head is cutting, and the resulting cutting line has no flaws, which can ensure the integrity of the cutting pattern.

A blade storage array is detachably mountable with a tissue log cutting saw. The saw has a cutting arm with a tool holder receptacle adapted and configured to hold a circular saw blade for the saw. The array has a plurality of storage units. Each storage unit is adapted and configured to store a circular saw blade for the saw. Each storage unit has a tool holder receptacle adapted and configured to hold a circular saw blade. Each storage unit is adapted and configured to move perpendicularly to the saw blade center axis.

A combination printer and cutting device for printing upon and cutting a web of media or tag stock into individual units. The device may cut vinyl, plastic, or RFID stock material as it moves through the printer in both back and forth directions. The device comprises a printer and a cutting apparatus that is further comprised of a carriage assembly and a movable cutter assembly. The cutter assembly is easily interchangeable and comprises a cutting element such as a wheel blade, and a pressure adjusting element for adjusting the amount of pressure applied by the cutting element to the stock material. Alternatively, the cutter assembly may be manufactured with a predetermined pressure load, but still permit an operator to adjust the depth of cut. The cutting apparatus is adaptable for use with both new and existing printers.

According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

A slicing machine cuts slices of cutting material. The slicing machine has: a machine housing holding a motor and circular blade driven by the motor; a product feed, which feeds the cutting material to the circular blade; a stop plate; and a slidably arranged carriage, which feeds the cutting material to the blade. The blade is mounted directly on a bearing shaft arranged in the drive motor for the circular blade. The drive motor includes at a stator and rotor, which is detachable from the stator. The stator is in the machine housing. The machine housing has an insertion opening where, in the assembled state, the stator is arranged and through which the rotor is at least partially inserted into the stator. The slicing machine has an attachment device comprising at least one fastener that is configured to fasten the rotor and the stator to the machine housing.

A quick-change cutting assembly includes a base having a support surface for supporting a cutting blade, a clamping arm having a clamping surface, a spring interposed between the base and the clamping arm, and a pivot defining a pivot axis between the spring and the clamping surface that couples the clamping arm to the base. The spring biases the clamping surface toward the support surface and a cutting blade therebetween. The clamping arm is pivotable between a closed position where the clamping surface is parallel to the support surface and an open position removed from the closed position where the clamping surface is spaced further from the support surface. The cutting assembly further includes a locking pin transverse the direction of biasing action of the spring that connects the clamping arm to the base to prevent the clamping arm from pivoting relative to the base when in the closed position.

A cutting apparatus includes a mount flange having a mount land that has a surface for holding a cutting blade as a consumable part, a changing apparatus for changing cutting blades, and a moving unit for moving the changing apparatus between a changing position for changing cutting blades and a retracted position. The changing apparatus includes a rotational shaft, a first holder for holding a used cutting blade, the first holder having a first holding surface facing in an outward direction from the rotational shaft perpendicularly to the rotational shaft, and a second holder for holding a replacement cutting blade, the second holder being disposed in a position angularly spaced a predetermined angle from the first holder around the rotational shaft, the second holder having a second holding surface facing in an outward direction from the rotational shaft perpendicularly to the rotational shaft.

A cutting apparatus includes a blade changing apparatus for changing a cutting blade mounted on a spindle of a first cutting unit and changing a cutting blade mounted on a spindle of a second cutting unit. The blade changing apparatus includes a nut mounting and demounting unit for mounting and demounting a nut in each of the first and second cutting units and a blade mounting and demounting unit for mounting and demounting the cutting blade in each of the first and second cutting units. The nut mounting and demounting unit includes a rotating shaft, a first nut rotating portion fixed to one end of the rotating shaft, a second nut rotating portion fixed to the other end of the rotating shaft, a motor, and a power transmitting unit connected to the motor and the rotating shaft.
