A printer has a fixed blade, a movable blade configured to be displaced relative to the fixed blade, and the movable blade has a first movable blade portion inclined from one longitudinal end toward a substantially longitudinal center in a direction opposed to the fixed blade, and a second movable blade portion, which is separated from the first movable blade portion, inclined from another longitudinal end toward the substantially longitudinal center in the direction opposed to the fixed blade. The printer has a holding member configured to rotatably hold the first and second movable blade portions so that a shearing angle formed by the fixed blade and the first or second movable blade portion is variable, and an elastic deformable member configured to urge the first and second movable blade portions in a predetermined direction and elastically deformable, depending on a magnitude of a cutting resistance.

A conversion apparatus is provided herein. The conversion apparatus includes a cutting member having an edge configured for cutting the dunnage material. The conversion apparatus also includes a biasing member that is located adjacent to the cutting member such that the dunnage material passes between the biasing member and the cutting member. The biasing member operably contacts the dunnage material thereby biasing the dunnage material against the cutting member. The position of the biasing member relative to the cutting member is such that in response to the dunnage material being retracted back into the conversion apparatus the cutting member begins to sever the dunnage material, but in response to the dunnage material traveling in the dispensing direction the cutting member does not begin to sever the dunnage material due to the relative position.

Provided is a method for producing a separator which method less causes a tear in the separator. The method is a method for producing a separator by slitting, in a direction in which a separator original sheet (12b) being porous is conveyed, the separator original sheet (12b) into a plurality of separators (12a), including the steps of: (a) conveying the separator original sheet (12b) in a state where the separator original sheet (12b) is in contact with a roller (77); and (b) slitting the separator original sheet (12b) at a portion where the separator original sheet (12b) is in contact with the roller (77).

A tool for use with wrapping paper comprises a unitary, plastic stick and a length of at least 18 inches. The stick extends linearly and has serrations defined in the plastic stick on a first side and has a non-serrated second side, opposite the first side, separated by a width. The serrations are adjacent a bracing surface and are parallel to the wrapping paper when the bracing surface is disposed on top of the wrapping paper. In particular embodiments, a non-skid feature can be added to the bracing surface, as well as a lip to self-orient the tool relative to the edge of wrapping paper. The tool can be provided within the hollow central core of a roll of wrapping paper, and enclosed therein by a clear plastic wrap. A product resulting from a 3D printing process is also described.

A good-quality slit separator having a small amount of fuzziness at a slit part thereof is to be obtained. The present invention includes: a step (S101) of conveying an original sheet (S); and a step (S102) of slitting the original sheet (S) by causing a plurality of slitting blades (72) to cut into the original sheet (S) such that tangent plane angles (63) in a tangent plane, on which a slitting position is in contact with the original sheet (S), are substantially identical with each other.

A printer detects when printing paper S is cut by a head cover 32, and includes a vibration detector 71 for detecting vibration, a cut decision mechanism 72 for determining based on output from the vibration detector 71 if the printing paper S was cut by the head cover 32, and a cut report transmitter that reports that the printing paper S was cut.

A printing mechanism has: a head mechanism including a printing head configured to print on a recording paper; a platen mechanism including a platen roller configured to nip the recording paper with the printing head to feed the recording paper; a fixed blade arranged in one mechanism of the head mechanism and the platen mechanism; and a movable blade arranged in another mechanism of the head mechanism and the platen mechanism in a slidable manner and configured to cut the recording paper with the fixed blade, the another mechanism comprising: a movable blade guide wall arranged upstream of the movable blade in a paper path direction of the recording paper; a first rib protruding from the movable blade guide wall to downstream of the paper path direction; and a second rib formed at a position on the movable blade guide wall, which is separated from the fixed blade with respect to the first rib in a movement direction of the movable blade.

An actuator assembly including a mounting device, a manual actuator rotatably mounted on the mounting device, and a cutting mechanism. The cutting mechanism is disposed in a gap that is formed between the manual actuator and the mounting device. The cutting mechanism is structured to cut a ligature inserted into the gap.

A good-quality slit separator having a small amount of fuzziness at a slit part thereof is to be obtained. The present invention includes: a step (S101) of conveying an original sheet (S); and a step (S102) of slitting the original sheet (S) by causing a slitting blade (72) to cut into the original sheet (S) such that a d tangent plane angle (.sub.3) in a tangent plane, on which a slitting position is in contact with the original sheet (S), is in a range of not less than 3 to not more than 35.
