A slitting machine for removing a strip from a sheet of material. The slitting machine has a blade assembly with first and second cutting blades, and a perforating blade arranged between the first and second cutting blades. The first and second cutting blades are arranged to cut the sheet of material to define the strip and the perforating blade is arranged to perforate the sheet of material to define an end of the strip.

A slit device including a first transport section which transports a web in a transport direction while nipping the web, a second transport section which is disposed in parallel with a direction intersecting the transport direction of the first transport section and which transports the web in the transport direction while nipping the web, and a cutting section which is disposed between the first transport section and the second transport section in a direction intersecting the transport direction and which cuts the web along the transport direction, in which a cutting position at which the web is cut by the cutting section is a position within a nipping area where the first transport section nips the web along the transport direction, or is a position downstream of the nipping area in the transport direction.

The invention relates to a method for optimizing a shearing bench for shearing a film having a thickness less than or equal to 10 microns, the shearing bench comprising a plurality of elements, each element being characterized by a plurality of parameters, the collection of parameters forming the parameters of the shearing bench, the plurality of elements comprising at least one blade assembly comprising a blade and a counter-blade collaborating with the blade, a system for progressing the film, and a system for urging the blade and the counter-blade against one another in order to shear the film.

A device for the longitudinal cutting of a wide food band of a soft food mass which is moved in a conveyance direction on a conveyor belt, wherein a cutting cylinder rotating in the conveyance direction is provided on which is mounted a number of cutting disks disposed coaxially to the rotational axis A for cutting into the food band with the edge thereof, wherein a comb having a plurality of comb tines is provided, which in an operating position engage into the intermediate spaces between the cutting disks during the longitudinal cutting in order to hold down the cut strips on the conveyor belt, wherein the comb is held on a comb holder so as to be pivotable about the rotational axis, wherein the comb holder can be transferred from the operating position and a maintenance position by pivoting about the rotational axis.

A sheet processing apparatus includes: at least one processing tool that takes a processable state and an unprocessable state; a setting unit that sets operation parameters on the processable state and the unprocessable state; and a control unit that controls an operation of the processing tool based on the set operation parameters, in which the setting unit sets the operation parameters such that: a processable state holding process in which the processing tool holds the processable state, is executed, when a certain portion-to-be-processed is formed in a certain pre-product and then a next portion-to-be-processed of the same type as the certain portion-to-be-processed is formed in a next pre-product; and/or a processing tool selection process in which the processing tool for forming the portion-to-be-processed is selected so that a moving distance of the processing tool is minimized, is executed.

A cutter cassette for a packaging machine, the cutter cassette includes a blade shaft on which at least one longitudinal cutting blade is arranged. The blade shaft can be transferred in a reversible manner from a transporting position into an operating position by lowering the blade shaft relative to a housing. The lowering of the blade shaft takes place under gravitational force.

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 (.sub.3) in a tangent plane, on which a slitting position is in contact with the original sheet (S), are substantially identical with each other.

The invention relates to a cutting machine for cutting cardboard, paper or the like, comprising an aligning station having a horizontal bedplate provided with sheet shifting means and stop means arranged along the forward movement direction of the sheet and configured for being in contact with one of the sides of the sheet for guiding the movement for shifting the sheet. Additionally, the machine comprises a cutting station provided with cutting means arranged in a transverse direction with respect to the forward movement direction of the sheets for dividing the sheets into longitudinal sections, and sheet shifting means for shifting the sheets in the forward movement direction which coincides with a longitudinal axis of the cutting station, said cutting means being provided for dividing each sheet into portions, a longitudinal axis of the bedplate of the aligning station having, when seen in plan view, an angle of inclination with respect to the longitudinal axis of the cutting station.
