A printer configured to cut recording paper with a fixed blade and a movable blade has a blade unit including the movable blade and a slider to which the movable blade is attachable, and the slider includes: a contact part configured to contact the movable blade; a flexible part formed thinner than the contact part; and a first protrusion provided on the flexible part and configured to engage with a first opening provided in the movable blade.

A cutter and cutter-holder matching method includes: transferring a cutter holder to a temporary cutter-holder placement module by a first clamping module; heating the cutter holder by a cutter-holder heating module for expanding a cutter clamping hole of the cutter holder; inserting a part of a cutter into the cutter clamping hole of the cutter holder by a second clamping module; cooling the cutter holder by a cutter-holder cooling module for contracting the cutter clamping hole of the cutter holder so as to tightly clamp the cutter; and transferring the cutter holder with the cutter to an assembly storage module by the first clamping module.

Embodiments of the invention provide a cutting tool. The cutting tool includes a pin that defines an axis, a first jaw, a second jaw, a first blade, and a second blade. The first and second jaws are configured to rotate about the axis. The first jaw includes a first ear surface that has a first ear bore that is dimensioned to receive the pin. The second jaw includes a second ear surface rotationally engaged with the first ear surface and includes a second ear bore that is dimensioned to receive the pin. The blades can include a tapered face and a non-tapered face. The first and second ear surfaces can be coplanar with the respective non-tapered face.

An improved detachable cutting assembly used in a food cutting machine includes a rotating disc with a window and a pivot hole. A flap is connected radially to the rotation axis of the cutting machine by its insert ring. The insert ring includes a fixing area in which at least one nut is embedded and on which there is at least one fastening hole coinciding with the at least one nut, and a lifting wedge on which a blade is partially embedded, leaving the cutting edge of the blade protruding on the upper face of the rotating disc through the window of the rotating disc. Existing in the fixing area of the rotating disc, there is at least one fastening hole coinciding with the at least one fastening hole and the at least one nut of the flap and capable of fixing the whole assembly by linking elements.

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.

Disclosed is a pouch cutting apparatus for secondary batteries, which cuts remaining portions of a terrace of a pouch-type secondary battery except for folded portions, the pouch cutting apparatus including a frame, a lower cutting unit fixed to a lower side of a front surface of the frame and configured to support a lower portion of the terrace in a longitudinal direction of the terrace so that the remaining portion extends to the outside of a rear surface thereof in a state in which the pouch-type secondary battery to be cut is fixed, and an upper cutting unit disposed at an upper side of the front surface of the frame so as to be movable upward or downward and configured to cut the remaining portion extending to the outside of the rear surface of the lower cutting unit.

The present invention relates to a yarn clearer for a workstation of a textile machine with a cutting device for clearing out defects from a yarn, as well as a cutting device for a yarn clearer which is configured to be arranged on a workstation of a textile machine, with a cutting knife with a cutting edge adjustable between a rest position and a cutting position, and an anvil arranged on an anvil carrier in an operating position in which a stop surface of the anvil interacts with the cutting edge of the cutting knife in the cutting position. In order to provide a yarn clearer with a cutting device as well as a cutting device with a cutting knife and an anvil, which is characterised by a long service life, there is provision for the anvil to have at least two stop surfaces which are configured to be arranged on the anvil carrier in the operating position and is adjustably arranged on the anvil carrier for the selection of the stop surface which is configured to be brought into an active connection with the cutting edge.

The present invention provides a light-weight spacer for a slitting machine for maintaining the width between slitting knives. The light-weight spacer comprises: a spacer body having a ring structure integrally formed of metal; an inner surface positioned on the inner side of the ring structure and extending along the central axis of the ring structure; an outer surface positioned on the outer side of the ring structure and extending along the central axis of the ring structure; a first side surface extending between the inner surface and the outer surface and being perpendicular thereto; a second side surface opposite to the first side surface and extending between the inner surface and the outer surface; a first plurality of perforations provided on the first side; and a second plurality of perforations provided on the second side.

A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.
