A fin according to the present disclosure is a corrugated fin formed of a metal plate by bending into a corrugated shape, and the corrugated fin includes peak portions extending in a first direction, valley portions extending in the first direction, and inclined portions connecting the peak portions and the valley portions adjacent to each other. The peak portions and the valley portions are alternately arranged in a second direction perpendicular to the first direction, and a thickness of the metal plate at each apex of the peak portions and the valley portions is larger than a thickness of the inclined portions of the metal plate.

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.

The invention relates to a device for producing a sheet-metal blank by means of laser cutting, including a laser cutting device having a laser cutting head movable back and forth in a transport direction and in a y-direction extending vertically to the transport direction, and a stretching device for stretching a metal sheet accommodated in the laser cutting device. The device includes a first clamping device provided upstream of the laser cutting device for clampingly gripping a first portion of the metal sheet, a second clamping device provided downstream of the laser cutting device for clampingly gripping a second portion of the metal sheet, and a mechanism for changing a distance between the first and the second clamping device such that a tensile stress is exerted onto a metal sheet that is clampingly gripped therewith.

A manufacturing assembly for manufacturing a metal part comprises a flattening module having a trolley and at least one pressing roller. The flattening module is movable along a stapling line of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction. The pressure increases auto-adaptively with an altitude of the free surface in a direction opposite the determined pressing direction.

Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip material positioned between an entry and an exit of an apparatus. A sensor determines a measured distance between an upper surface of the strip material and a reference location, where the sensor is downstream from the exit of the apparatus. A controller determines a difference value between the measured distance and a predetermined distance to detect material curvature in the strip material.
