A method for unpacking a workpiece, in particular an optical lens or an optical lens blank, from a package, includes an automated cutting open step of a first package side of the package, and an automated sliding of the workpiece out of the package step on the first package side. An unpacking apparatus for unpacking a workpiece from a package, has a feed station for receiving a package in which a workpiece is arranged, a cutting-open station having a first cutting or sawing tool for the automated cutting open of a first package side of the package downstream of the feed station, and a slide-out station downstream of the cutting-open station. A relative movement can be produced between the package and the workpiece in an automated manner so that the workpiece slides out of the package on the first package side.

A cutting apparatus for slicing and/or dividing meat products, in particular bacon and/or fresh meat products, comprises a product feed that is configured to guide at least one first product and at least one second product simultaneously into a cutting region in which slices and/or pieces are cut off from the products by means of a first rotating blade and by means of a second rotating blade. In this respect, the product feed has a first conveying means for guiding the at least one first product into the cutting region and a second conveying means for guiding the at least one second product into the cutting region, wherein the first blade is associated with the first conveying means and is provided for cutting off slices and/or pieces from the at least one first product, and wherein the second blade is associated with the second conveying means and is provided for cutting off slices and/or pieces from the at least one second product.

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 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 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 cutting apparatus includes a mount flange having a mount land that has a surface for holding a cutting blade as a consumable part, a changing apparatus for changing cutting blades, and a moving unit for moving the changing apparatus between a changing position for changing cutting blades and a retracted position. The changing apparatus includes a rotational shaft, a first holder for holding a used cutting blade, the first holder having a first holding surface facing in an outward direction from the rotational shaft perpendicularly to the rotational shaft, and a second holder for holding a replacement cutting blade, the second holder being disposed in a position angularly spaced a predetermined angle from the first holder around the rotational shaft, the second holder having a second holding surface facing in an outward direction from the rotational shaft perpendicularly to the rotational shaft.
