A workpiece transport unit including a pair of arms, an opening/closing mechanism configured to open and close the pair of arms in a horizontal direction, a pair of first placement surfaces provided at the pair of arms and configured for a first workpiece to be placed thereon, and a pair of second placement surfaces provided at the pair of arms and configured for a second workpiece to be placed thereon.

A plant for producing a structured cross-channel packing element. The structured cross-channel packing element comprises at least two adjacent layers made of expanded metal sheets each comprising periodic deformations. The plant comprises a stretching machine configured to cut and stretch a metal sheet to form one of a plurality of first expanded metal sheets, a calibration machine configured to roll the first expanded metal sheets to a desired thickness, a sheet storage unit configured to directly receive each of the first expanded metal sheets rolled in the calibration machine, a forming machine configured to form each of the first expanded metal sheets to form the expanded metal sheets comprising periodic deformations, and a stacking machine configured to stack the expanded metal sheets comprising periodic deformations to form the structured cross-channel packing element. The sheet storage unit is configured to release the first expanded metal sheets directly to the forming machine.

A tensioning device for winding metal pipes into a coil contains an upper replaceable roller and two lower replaceable rollers mounted with the possibility of rotation. The upper roller is mounted with the possibility of vertical movement. The device is equipped with a caliper with the possibility of longitudinal movement, a housing mounted on the caliper with the possibility of rotation around the axis and fixation. The housing contains a control unit for longitudinal movement of the caliper depending on the angular movement of the spindle shaft at a given step of winding metal pipes. The upper and lower rollers are mounted in conical bearings in the housing and are made multi-pass with a distance L between the centers of the passes, which sets the winding density of the coil. The upper roller is installed with the possibility of vertical movement by means of sliders and adjusting screws.

A sheet metal processing cell has a stacker with a stack forming portion for receiving a length of sheet metal and positioning the sheet metal to be received in the stack. A part capture table is movable between an inserted position where the part capture table is positionable within the frame of the stacker below the stack forming portion and above the exit conveyor, and a withdrawn area where the part capture table is positioned outside of the frame of the stacker. When the part capture table is in the inserted position, the part capture table can receive a captured length of sheet metal from the stack forming portion and/or transfer the captured length of sheet metal from the part capture table to the stack. The part capture table has a conveyor for conveying the captured length of the sheet metal off the part capture table onto the stack.
