The first moveable die head is configured to receive a first moveable die comprising a first body length and a second die head is adapted to receive a second die comprising a second body length. At least one of the moveable die or the stationary die comprises an elongated die.

A process and system provides for atraumatic preparation of morcelized Tissue Particles (MTPs), such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The MTPs may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.

A carton sizing system (1) that has a frame (2), a controller (4), one or more cutters (51) movably mounted to the frame (2) and operatively connected to the controller (4), one or more markers (61) movably mounted to the frame (2) and operatively connected to the controller (4). The carton sizing system (1) also has a measuring system (7) that is operatively connected to the controller (4) and configured to determine, in use, the footprint of an open top carton and to determine the height of one or more objects contained within the carton. The controller (4) is configured to position the one or more cutters (51) based on the determined footprint and to cut vertical edges of the carton based on the determined height and also to position the one or more markers (61) based on the determined footprint and eight and to score or crease vertical walls of the carton between the vertical edges to at least partially define foldable panels.

A cutting mechanism is provided for a dunnage conversion machine 10 that selectively cuts dunnage sheet stock drawable through the cutting mechanism. The cutting mechanism includes a frame and a pair of opposed cutting blades through which the sheet stock is drawable. The cutting blades include a driven blade and a biased blade, each supported relative to the frame for movement into and out of contact with one another. The driven blade is movable towards the biased blade to cut the sheet stock. The biased blade is biased against movement away from the driven blade to allow for self-adjustability to counter wear of one or both of the opposed blades. Contact of the opposed blades with one another causes the biased blade to be deflected away from the driven blade.

An anti-stuck driving device comprises: a movable blade, a movable blade driving unit, and a controller. The movable blade driving unit comprises a transmission assembly, a motor configured to drive the transmission assembly, and a connecting element connected between the transmission assembly and the motor. The transmission assembly links the movable blade moving back and forth linearly. The controller connects to the motor. When the movable blade is stuck, the controller controls the motor to drive the connecting element to rotate in reverse to separate the transmission assembly and the connecting element, and release a resistance of the transmission assembly. The present invention also discloses a printer using the anti-stuck driving device with malfunction repairing.

Size-reduction units, size-reduction machines, and methods capable of producing size-reduced products from a variety of solid and semisolid materials. A size-reduction unit includes a circular cutter adapted and arranged to cut a product into strips, a rotating cross-cutter adapted and arranged to receive the strips from the circular cutter, and a stripper plate. The cross-cutter has knives with cutting edges that are adapted and arranged to cut the strips into a size-reduced product, and the stripper plate defines a shear edge in proximity to the cutting edge of each knife of the cross-cutter as its cutting edge encounter the shear edge during rotation of the cross-cutter. The cross-cutter has a helical fluted shape comprising flutes between adjacent pairs of the knives.

A cutter mechanism for a printer is provided. The cutter mechanism comprises a rotary cutter and a straight blade assembly. The rotary cutter may be mounted for rotation about a rotation axis and for translation across at least a portion of a width of a paper path perpendicular to the rotation axis. The straight blade assembly may be mounted for rotation about a shaft and adapted to cooperate with the rotary cutter. The straight blade assembly comprises a straight blade extending across the width of the paper path. A printer mechanism cover is mounted coaxially on the shaft so as to be movable between a closed position and an open position. A portion of the cover may impact the straight blade assembly when the cover is moved from the closed position to the open position, causing the straight blade to be moved away from the rotary cutter.

A cutter unit includes a first frame, a fixed blade, a movable blade, a movable blade drive mechanism and a pressure mechanism. The fixed blade has a first cutting edge portion. One end portion of the movable blade has one end configured to cut a cut item in cooperation with the first cutting edge portion. The second cutting edge portion and the first cutting edge portion contacting with each other at a first point and a second point. Another end portion of the movable blade has a contacting portion in contact with the first frame at a third point. The first point, the second point and the third point define an imaginary triangle. The pressure member presses the movable blade at a pressure contact position so that the movable blade presses against the fixed blade. The pressure contact position is positioned substantially within the imaginary triangle.

A sheet processor subjecting a sheet having been conveyed forward to processing along a direction perpendicular to a conveyance direction of the sheet, includes: a processing unit performing the processing; and a receiving unit receiving the processing unit therein in a state capable of perfecting the processing on the sheet, and the processing unit includes a first processing tool 4A and a second processing tool 4B disposed to vertically oppose each other with a conveyance surface of the sheet disposed therebetween, and the receiving unit includes at least one receiver that removably receives the first processing tool 4A and the second processing tool 4B in the state capable of performing the processing on the sheet, with arbitrarily selected one of the first processing tool 4A and the second processing tool 4B disposed above the conveyance surface, and with arbitrarily selected another of the first processing tool 4A and the second processing tool 4B disposed below the conveyance surface.

A carton sizing system that has a frame, a controller, one or more cutters movably mounted to the frame and operatively connected to the controller, one or more markers movably mounted to the frame and operatively connected to the controller. The carton sizing system also has a measuring means that is operatively connected to the controller and configured to determine, in use, the footprint of an open top carton and to determine the height of one or more objects contained within the carton. The controller is configured to position the one or more cutters based on the determined footprint and to cut vertical edges of the carton based on the determined height and also to position the one or more markers based on the determined footprint and height and to score or crease vertical walls of the carton between the vertical edges to at least partially define foldable panels.
