A modular comb element for a machine for automatically cutting a mat of sheets of material. The cutting machine includes a plurality of cutting supports. The comb element includes a plate forming a support from which a first and a second row of teeth extend longitudinally. The teeth of the first row alternate with the teeth of the second row, and a free end of the teeth of the first row are farther from a downstream edge of the support than a free end of the teeth of the second row of teeth. A ramp is mounted on the downstream edge of the support and inclined with respect to the latter so as to limit the contact surface between the mat of sheets and the comb element. Air injection means are at a downstream edge of the ramp over an entire width thereof.

A cardboard box dividing device and a cardboard box production device are provided with: lower conveyors on which a plurality of connected cardboard box bodies are stacked and transported; a pressing device pressing the plurality of connected cardboard box bodies stacked on the lower conveyors from above; a cutting knife disposed along a width direction of the connected cardboard box bodies and dividing the plurality of connected cardboard box bodies stacked on the lower conveyors into a front part and a rear part; and a lifting/lowering device lifting and lowering the lower conveyors and the pressing device.

A sheet material machining system includes a sheet material machining machine which is configured to machine a workpiece to produce a machined workpiece that includes a plurality of products and a residual material. The machined workpiece is configured to be placed on a sorting table. The plurality of products are configured to be placed on a temporary placement table. At least one product among the plurality of products are configured to be placed on a discharge table. A carrier includes an attracting actuator and a mobile actuator. The order management processor is configured to control the carrier and includes a storage configured to memorize a layout of the plurality of products in the workpiece. The plurality of products are associated with an attracting order.

A cutting machine that includes a knife and an unrolling device. The knife severs foodstuff slices from a foodstuff bar. A leaf from a separating material is provided between at least two foodstuff slices. The unrolling device providing the separating material for disposal of the leaf between the two foodstuff slices and injecting the leaf into the cutting region. The unrolling device has a tape roll and a delay unit. The delay unit along a transporting movement of the separating material is disposed downstream of the tape roll. The delay unit is configured for delaying the transporting movement of the separating material, which is unrolled from the unrolling device and is provided in a cutting region of a cutting machine. The delay unit has a pressure-generating means for exerting pressure on the separating material, and a suctioning means for suctioning the separating material by means of negative pressure.

A front end conveyor include a lower deck having a plurality of lower sheet supports, an upstream upper deck having an upstream end at the upstream end of the front end conveyor, a downstream end and a plurality of first upper sheet guides and a downstream upper deck having an upstream end, a downstream end at the downstream end of the front end conveyor, and a plurality of second upper sheet guides. The lower sheet supports and the upper sheet guides define a sheet transport path for moving sheets of material though the conveyor. The downstream end of the upstream upper deck and the upstream end of the downstream upper deck are independently pivotably mounted to the frame such that the upstream end of the upstream upper deck and the downstream end of the downstream upper deck shiftable toward and away from the lower deck.

A job includes pages that have multiple items positioned according to coordinates. A sheet coordinate location identifier for each of the items (that corresponds to the coordinates for the items) is added to the job. The job is printed to produce printed sheets of items (printed items) printed according to the coordinates. A cutting device cuts the printed sheets, according to the coordinates, into individually cut items. Each of the cut items includes the sheet coordinate location identifier printed thereon, and this identifies the pre-cutting locations of the cut items within the uncut sheets of print media. The cut items are inspected for cutting defects to identify defective items. Pre-cutting locations of the defective items are identified using only the sheet coordinate location identifier printed on the defective items. A repair recommendation for the cutting device is based on the most common pre-cutting location of the defective items.

A defect detection device that detects the position of defective parts in a core paper. The device includes a slitter/scorer that cuts a continuous double-sided cardboard sheet along a transport direction. The device includes a cutoff that cuts off a plurality of continuous double-sided cardboard sheets along a width direction to a prescribed length, the continuous double-sided cardboard sheets having been cut to a prescribed width. The device includes a web director that distributes the plurality of continuous double-sided cardboard sheets to respective conveyance tables. The device includes a defective-product-eliminating device that eliminates plate-shaped double-sided cardboard sheets from a conveyance line. The device includes a control device that specifies the plate-shaped double-sided cardboard sheets having defective parts on the basis of the position of the defective parts and the width-direction cutting position on the continuous double-sided cardboard sheets, and operates the defective-product-eliminating device handling the plate-shaped double-sided cardboard sheets.

Method for cutting media from a multi-roll printing system, comprising the steps of: selecting one of a first medium and a second medium, which first medium and second medium are output in parallel with respect to one another from the multi-roll printing system; transporting the selected medium to a cutting media transport path spaced apart from a further media transport path in a traverse direction perpendicular to a plane of the cutting media transport path; and cutting the selected medium positioned at the cutting media transport path. The present invention further relates to a cutting assembly and a multi-roll printing system.

A job includes pages that have multiple items positioned according to coordinates. A sheet coordinate location identifier for each of the items (that corresponds to the coordinates for the items) is added to the job. The job is printed to produce printed sheets of items (printed items) printed according to the coordinates. A cutting device cuts the printed sheets, according to the coordinates, into individually cut items. Each of the cut items includes the sheet coordinate location identifier printed thereon, and this identifies the pre-cutting locations of the cut items within the uncut sheets of print media. The cut items are inspected for cutting defects to identify defective items. Pre-cutting locations of the defective items are identified using only the sheet coordinate location identifier printed on the defective items. A repair recommendation for the cutting device is based on the most common pre-cutting location of the defective items.

When a length in a conveying direction of a margin to be cut off is shorter than a predetermined distance between a cutting part and a second conveying part, a sheet cutting machine feeds a first sheet to the cutting part using a first conveying part while keeping the second conveying part positioned at a conveying path. When the length is equal to or longer than the predetermined distance, the machine feeds the first sheet to the cutting part using the first conveying part after upwardly retracting the second conveying part from the conveying path using a retracting mechanism.
