Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.

An apparatus for ventilating a web of material used in the manufacture of pocketed springs may be removably attached to a pocket coiler. The apparatus has an upper movable portion which pivots relative to a stationary portion. The stationary portion may be removably attached to the pocket coiler. Each portion has at least one roller, a web of material passing between the rollers during use. One of the rollers may have protrusions to create openings in the material before the material enters the pocket coiler.

A medium processing device (10) includes: a processing unit (56) that presses and processes a sheet-like medium (S); a processing-unit driving mechanism (20) that can execute a first operation of moving the processing unit 856) in a first direction (X) along a sheet surface (S1) of the medium (S) and a second operation of changing a height position of the processing unit (56) from the sheet surface (S1); and a relative moving mechanism (18) that relatively moves the medium (S) with respect to the processing unit (56) in a second direction (Y), wherein the processing-unit driving mechanism (20) includes: a guide member (21) guides the processing unit (56) so as to be movable in the first direction (X); and a support shaft (25, 26) disposed at a position closer to the medium than the guide member (21) and having the first direction (X) as a shaft center (C1), and the second operation is set as an operation of integrally changing a height position of the processing unit (56) from the sheet surface (S) with the guide member (21) along with rotation of the support shaft (25, 26) about the shaft center (C1).

A cutting device is provided for cutting a conveyed plate-shaped body. The cutting device includes a rotary cutter and a lifting device. The rotary cutter includes a lower unit. The lower unit is disposed below the plate-shaped body, and includes a roll and a lower blade attached to the roll. The lifting device is disposed on the lower unit, and lifts up the plate-shaped body.

An excess screen mesh trimmer to trim excess mesh from flexible screen frames to which the mesh is at least partially fused, including a trimmer assembly including at least a first rotating blade having a sharpened outer perimeter edge and a screen frame supporting assembly that supports a flexible screen frame proximate the trimmer assembly and proximate the at least first rotating blade perimeter edge in a parallel orientation to a portion of the screen frame A supporting frame supports the trimmer assembly and the screen supporting frame. Also, a method of trimming excess mesh from flexible screen frames placing the flexible screen frame in contact with a portion of an infeed fence and advancing the flexible screen frame in a direction parallel to the portion of the infeed fence and severing the excess screen mesh from the flexible screen frame proximate the flexible screen frame.
