A method for joining edges and/or surfaces of a profile in a profiling installation for longitudinally forming a virtually endless material strip into an at least partially closed profile shape. The material strip or profile is formed roll forming tools into a profile which is closed or partially closed, and is fixed in a joining zone, with a longitudinally running joining seam being formed. The profile passes in the joining zone through a joining roller arrangement and/or planar joining arrangement to feed the profile to a joining point and to stabilize the profile there, and/or to ensure that it is dimensionally stable during and after joining. Forces or magnitudes of force components which act on the profile from at least one of the joining rollers and/or a subsection of the planar joining arrangement are detected in the joining zone. A planar joining arrangement and a profiling installation are also provided.

Method and installation for manufacturing and inspecting metal containers. The method includes extruding a metal disk to form a metal container having a cylindrical body with a side wall, a base, and an open end opposite the base. After the metal container is formed the thickness of the base is determined by arranging the base between an X-ray emitter and an X-ray receiver and emitting X-rays from the X-ray emitter to the X-ray receiver through the base. The thickness of the base is determined based on the intensity of the X-rays absorbed by the base.

A machine for machining sheet metal parts has a plurality of machining stations along a continuous conveyor belt, including a first sanding belt unit with an endlessly rotating sanding belt, a brush unit with horizontally rotating abrasive brushes and a second sanding belt unit with a fine-grained sanding belt. The three machining stations can be adjusted independently, and the machining tools are interchangeable. The technical data of the machining tools is stored in a tool memory. The machine includes a device for providing a suggestion for an optimal adjustment as well as an operator terminal with a touch screen, via which the user can make inputs and/or receive information from or about the machine. Based on the data entered by the user and the data stored in the machine, the user receives a suggestion for the optimal adjustment of the machine and is prompted to change the tool if necessary.

The present disclosure is directed to remedying a non-conforming feature of an aluminum alloy part. A method may include identifying a yield strength as a function of temperature for a designation of the aluminum alloy part, determining a stress to be applied to the feature to re-form the non-conforming feature to within a dimensional tolerance, correlating the stress to the identified yield strength to determine a process temperature of the part upon applying the stress to the feature, determining a time duration for applying the stress to the feature at the determined process temperature, and applying the stress to the feature of the part, the feature being restrained to oppose the stress, while heating the feature to the determined process temperature, and maintaining the application of the stress and the heat to the feature for the time duration in order to reform the restrained feature to within the dimensional tolerance.

An edge crack detection apparatus for detecting an edge crack of a metal plate being conveyed includes: a detection part including a plurality of elements arranged along a plate width direction of the metal plate, each of the plurality of elements being configured to be capable of detecting presence or absence of the metal plate at a position of the element in the plate width direction; a plate edge position determination part configured to determine a plate edge position of the metal plate in the plate width direction on the basis of a detection result of each of a plurality of first elements positioned within a first region in the plate width direction, from among the plurality of elements; and an edge crack detection part configured to detect an edge crack of the metal plate on the basis of a detection result of each of a plurality of second elements selected on the basis of the plate edge position and positioned within a second region which is narrower than the first region in the plate width direction, from among the plurality of elements.

A roll press machine that presses-forming of a work is disclosed in which a plurality of electrode layers having been baked on a metal foil. The material is supplied as a work W into a gap between a lower roll and an upper roll for consolidating. As the work travels through the gap, a controlling device is configured to maintain the gap larger than a consolidating gap until the front edge of the work passes through the gap by a first predetermined distance, then maintain the gap equal to the consolidation gap until the rear edge of the work arrives downstream of the gap by a second predetermined distance, and maintain the gap larger than the consolidation gap until the rea edge leaves the gap.
