A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs a transverse conversion function, a longitudinal conversion function, and an angled conversion function on the sheet material to create the packaging templates. The converting machine includes a tool head with a converting instrument. The orientation of the converting instrument is adjustable to enable performance of the angled conversion function and at least one of the longitudinal conversion function and the transverse conversion function.

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.

In a device for machine-making a dunnage product from a single- or multi-ply continuous paper web comprising a delivery conveyor for drawing in a paper web into the device whereby a conveying direction is defined and a cutter for separating the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device, it is provided that a removal conveyor succeeds in the conveying direction to the cutter, the removal conveyor transporting the separated dunnage product away from the cutter.

A sheet processing machine includes a processing device including a processing blade; a drive shaft related to an operation of the processing blade; a shaft drive motor; a rotational position detection unit that detects a rotational position of the drive shaft; a width direction drive motor that moves the processing device; and a control unit, in which the control unit controls the shaft drive motor so that the drive shaft is at a predetermined rotational position based on the rotational position of the drive shaft detected by the rotational position detection unit, and controls the width direction drive motor so that the processing device moves to a predetermined processing position while the drive shaft maintains the predetermined rotational position.

A cutting equipment which trims strips of webs in movement includes a stationary trimming blade and a rotating cylinder with a mobile trimming blade; the rotating cylinder includes a sector with suction openings connected to a vacuum source, which retains the strips by suction and drags the strips up to a strip collector; the cutting equipment cuts and separates transversal strips of two webs overlapped in adherence jointly to the cutting of basic sheets; a perforating device perforates a row of holes on the first web adjacent to an edge of the sheets; and a first web is positioned with the row of holes in front of the suction openings, while the strip of the second web is retained and dragged by suction through the holes of the first web up to the strip collector.

A perforated non-woven fabric having at least one fiber layer that has a plurality of through holes. The total area of the through holes accounts for 10˜80% of the total area of the perforated non-woven fabric; the opening of the through holes is flat with the surface of the perforated non-woven fabric; and the density of through holes on the perforated non-woven fabric is 3/cm.sup.2˜100/cm.sup.2. The fiber density at the edge of each through hole is similar to or the same as the fiber density in other areas of the perforated non-woven fabric. The fiber surrounds the through hole, and only the surface of the fiber is bonded to each other.

A sheet processing machine has at least one shaping device and at least one sheet delivery unit, arranged downstream of the at least one shaping device along a transport path provided for a transport of sheets. The at least one shaping device has at least one shaping point which is formed by at least one forme cylinder, on one hand, and at least one impression cylinder, on the other hand. At least one separation device, for removing scrap pieces from sheets, is arranged downstream of the at least one shaping point along the transport path provided for the transport of sheets. The at least one separation device has at least one separation transport device. At least one transport device, configured as a selective transport device, is arranged following the at least one separation transport device along the transport path provided for the transport of sheets. The transport device is configured as at least one upper suction transport device for a hanging transport of sheets.

A device for machine-making a dunnage product from a single- or multi-ply continuous paper web may include a delivery conveyor configured to draw the paper web into the device in a conveying direction; a cutter configured to separate the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device; and a removal conveyor positioned after the cutter in the conveying direction and configured to remove the separated dunnage product from the cutter.
