A conversion unit converting a first continuous web substrate into a second substrate in the form of converted blanks of predetermined length. On account of cutting tool rotation speed, the web moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement for producing a first run driving of the web, a sheeter having rotary tools for cutting the web into blanks, a second motorized arrangement for producing a second run driving of the substrate, the second arrangement being positioned in the immediate proximity of the sheeter, and at least one station having rotary tools for converting the blanks. A speed of rotation of the second arrangement varies during a cycle of rotation of the tools of the sheeter, comprising a phase at constant tangential speed, substantially equal to the speed of rotation of the tools of the sheeter, during which the cut is made, a speed reduction phase, during which a length of the web, dependent on the difference between the length of the blank and an extension of the periphery of the tools, is kept upstream of the second arrangement, and a speed increase phase, during which the substrate is discharged downstream of the second arrangement.

The present invention is an apparatus and method for cutting individual label strips from a roll of label web utilizing a cutter assembly. A label cutter comprises a cutter assembly for continuously and independently controlling the rotational speeds of a rotating cutter shaft, a stationary shaft, and a label feed roller is provided. The length of the label strip is controlled by the distinct speed of rotation of a stationary knife, the stationary knife is rotatably coupled to the stationary shaft. At least one cutter blade is operatively associated to the rotating cutter shaft for cutting the label web. The stationary knife rotates with a speed of rotation different from the speed of rotation of the cutter blade to produce longer or shorter label length strips. The frequency at which the cutter blade meets the stationary knife is inversely related to the length of the label strip that is produced during cut off.

An apparatus for the production a cushion product from a single- or multi-layer continuous paper strip includes a feed unit for drawing the paper strip into the apparatus, a cutting unit for cutting the cushion product from the paper strip, and control electronics for the activation of the cutting unit according to a predetermined motion profile. A sensor captures a rotation angle position of the feed unit. The control electronics are configured to activate the feed unit continuously and to start an activation of the cutting unit for a discontinuous cutting operation during capturing a predetermined actual rotation angle position of the feed unit.

A cutting unit comprising a cutting drum, a drum knife, a counterpart knife, and a double-joint controller that controls swiveling about a first joint, which swivels the counterpart knife between a cutting position and a waiting position, and swiveling about a second joint, which permits adjustment of a knife gap that forms between the counterpart knife and the drum knife in the cutting position. The drum knife is disposed on a circumference of the drum such that rotation of the drum guides the drum knife past the counterpart knife to cut a label when the counterpart knife is in the cutting position. In the waiting position, the counterpart knife is out of active engagement with the drum knife. The second joint permits adjustment of the knife gap such that the knife gap remains adjusted independently of swiveling about the first joint.

A cutting unit for providing transversal cuts and/or perforations to a string of packaging containers connected by transversal seals is provided. The cutting unit comprises a knife assembly and an anvil assembly rotatable against each other to form a nip for receiving a transversal seal of the string of packaging containers. The anvil assembly comprises an anvil blade having a first region and a second region such that when the first region is aligned with a knife blade of the knife assembly at the nip a cut is produced, and when the second region is aligned with the knife blade at the nip a perforation is produced. A method, a computer program and a computer-readable medium storing the computer program for providing transversal cuts and/or perforations to a string of packaging containers connected by transversal seals are also described.

A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.

A veneer cutting and sorting apparatus is disclosed. The apparatus includes a revolvable knife blade having a cutting edge and a revolvable knife edge receiver having a cutting edge receiving surface. The knife blade cuts a veneer sheet as peeled from a peeler block by a veneer lathe at a previously detected boundary between defective veneer portion and product veneer sheet on the cutting edge receiving surface then revolving at the same peripheral speed as the cutting edge of the knife blade. Cut-off defective portion is allowed to drop off by its own weight.

An apparatus for cutting a ribbon of food into strips. The apparatus includes a cutting apparatus toward which the ribbon of food is moved at a transport speed in a transport direction which has a grooved shaft and a cutting shaft. The grooved shaft has grooves which encircle the grooved shaft in the transport direction. The grooved shaft takes over the ribbon of food. The cutting shaft has cutting knives which encircle the cutting shaft in the transport direction. The cutting shaft is arranged opposite to the grooved shaft. The ribbon of food is guided between the cutting shaft and the grooved shaft. One respective cutting knife engages slightly into one respective groove disposed opposite thereto to cut the ribbon of food into the strips. The cutting shaft has a length of at least 600 mm. The grooved shaft has a length of at least 600 mm.

The lubrication device delivers a lubricant to the perforating device which provides intermittently spaced cuts to a moving web, also referred to as perforations. The lubrication device includes a retaining member, a plenum, and a comb having a plurality of comb channels. The plenum and the plurality of comb channels are in fluid communication with one another and deliver a lubricant to the perforating device. Lubrication of the perforating device in this manner may improve knife life, perforation quality and web handling.

Disclosed is a drug packaging device including a packaging unit and a cutting unit. The packaging unit includes a pair of packaging rollers that are pressed against each other with a drug packaging member disposed therebetween, thereby forming isolation regions in the drug packaging member at regular intervals so that at least one drug accommodation section can be formed between the isolation regions. The cutting unit forms a non-continuous zigzag cut line in which peak-shaped cuts and valley-shaped cuts are alternatively arranged and separated by a plurality of uncut portions. With this structure, it is possible to contribute to improvement in durability of a drug packaging member as well as in cuttability of the drug packaging member.
