The present invention is configured such that an adjustment nut for fixing spacers and blades repeatedly fitted to a shaft is provided with at least two concentricity adjustment screws, and, with the spacers and the blades fixed by the adjustment nut, the spacers and the blades are pushed by the concentricity adjustment screws in the direction of the shaft to enable concentricity adjustment, and thus, without causing defects, the blades are protected and can be used for a long time. In particular, according to the present invention, while one side shaft with respect to a diagnostic sheet is elastically supported, position adjustment in the longitudinal direction thereof is possible, and also projections are formed on the peripheries of the surfaces of the spacers facing the cutting edges of the blades thus to provide extra spaces for the blades in which the blades move, thereby preventing the deformation of cut strips and the damages on the blades.

A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing portion that houses the removed side edge part and is able to be pulled out from an apparatus body; a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the removed side edge part along the moving direction to the housing portion; and a second guide plate that is arranged between the housing portion and the guide plate, and is transformable into a first form having substantially mountain-shaped inclined surfaces in which both end portions of the second guide plate along the moving direction are lower than a center portion thereof, and a second form having substantially valley-shaped inclined surfaces in which both the end portions are higher than the center portion.

Abstract: The present disclosure provides an automatic cutting device for printed supports which allows to compensate for the space created between the sliding planes, so as to always sustain the support to be cut and allow it to pass from one sliding plane to another and reach the relative unloading rollers avoiding jam at the device outlet. This result is achieved by means of an array of fins supported at the second sliding plane, configured to move from a closed configuration, in which all the fins protrude from the second sliding plane towards the first sliding plane and occupy the transverse cutting zone, to an open configuration in which they leave the transverse cutting area free so as to allow undisturbed movement of the cutting unit. This array of fins in closed configuration sustains the printed support cut in the passage from the first sliding plane to the second sliding plane.

Disclosed is a cutter module to be used with a printing apparatus. The cutter module comprises a blade driving mechanism; and a rotary cutting blade driven by the blade driving mechanism. The blade driving mechanism comprises: a clutch mechanism selectively to enable the blade driving mechanism to drive the rotary cutting blade in a forward cutting direction or a backward direction. Also disclosed is a printing system comprising the cutter module and a method to be used with the cutter module.

A cutter arrangement for media processing equipment, including a cutter module to be arranged on a shaft via a dedicated one of a number of transmission devices, at least one of the cutter module and the transmission devices comprising a registration feature to guide a user to arrange the cutter module on the dedicated one of the number of transmission devices.

A sheet processing system conveys a material sheet in a first direction; calculates an inclination angle of the first registration mark of the material sheet with respect to the first direction; and includes cutting blades configured to cut the material sheet to produce sheet pieces and a cutting direction adjustment mechanism configured to adjust a cutting direction to a direction of the inclination angle. The sheet processing system conveys the sheet piece in a second direction; and includes a guide member configured to extend in the second direction and to guide a cutting end of the sheet piece, a processing place position identification section configured to identify a position on a conveyance path of a processing place of the sheet piece based on the inclination angle, and processing mechanisms configured to perform processing on the processing place whose the position on a conveyance path is identified.

A printing apparatus includes: a print head configured to eject ink based on print data; a conveyance unit configured to convey printing medium in a conveyance direction; a receiving portion configured to receive ink ejected beyond a first end of the printing medium in an intersecting direction, which intersects the conveyance direction; and a slitter configured to cut the printing medium in the conveyance direction at a predetermined position, wherein printing on one side of the printing medium in the intersecting direction is performed from the first end through the receiving portion, and wherein printing on the other side of the printing medium in the intersecting direction is performed beyond the predetermined position toward a second end side, which is on an opposite side of the first end.

A cutting device includes a drum section that rotates to convey a continuous body, and a cutting section that cuts the continuous body into multiple individual works. The drum section includes multiple holding heads that move while holding the respective works. The cutting section includes a cutter unit that moves together with multiple holding heads and that is smaller in number than the holding heads, and a cutter drive unit that moves the cutter unit independently of multiple holding heads. The cutter unit moves alongside of the continuous body from a certain cutting start position to cut the continuous body. The cutter drive unit returns the cutter unit that has cut the continuous body, to the cutting start position.

The invention relates to a packaging machine comprising an apparatus for cutting food packagings to size along a longitudinal direction, wherein the apparatus defines an inner space and an outer region, said apparatus having a first shaft, which extends in the inner space and on which at least a first cutting blade is arranged, and a second shaft which extends in the inner space and on which at least a second cutting blade is arranged, said second cutting blade forming a cutting unit arranged in the inner space together with the first cutting blade during operation, wherein the first cutting blade is axially displaceably supported on the respective shaft to change an axial spacing and an axial contact pressure between the first cutting blade and the second cutting blade of the cutting unit, and said apparatus having an adjustment mechanism, wherein the adjustment mechanism is coupled to the axially displaceable first cutting blade to displace the displaceable cutting blade in an axial direction. The invention furthermore relates to a method of setting a contact force between a first cutting blade and a second cutting blade of a cutting unit of a packaging machine.

In a sheet processing apparatus including a guide member that rotates by contact with a sheet processing unit, collision of the sheet processing unit with the guide member in a rotating state is avoided. A sheet conveyance apparatus includes: sheet processing units that move along one movement path intersecting a conveyance direction of a sheet; guide members that each include a fixed end rotatable about a rotation center line and support the sheet from below; a biasing member that biases the guide member so as to return to an original orientation in which a part of the guide member is located on the movement path; and a collision determination unit that determines, before at least one of the sheet processing units is moved and based on a movement start position and a target position of a movement target sheet processing unit and a size and an orientation before start of movement of the guide member, whether or not there is a possibility of occurrence of collision of the movement target sheet processing unit with the guide member in a rotating state.
