The present invention relates to a multipurpose spatula which has a separable pressing member on the outer surface of a body thereof, wherein the pressing member can be rotated as required to allow the other side surface thereof to be located on the end of one side pressing piece, so as to minimize the occurrence of scratches on sheets attached to advertising signs and tables, etc. and also to promote user conveniences.

A method includes compressing a non-dielectric, elastically-deformable component, a wire mesh component, and a dielectric, contoured object between first and second forming tools. Once the components are compressed, radio frequency energy is supplied to the first forming tool, thereby causing a radio frequency electromagnetic field to be generated between the first forming tool and the wire mesh component that results in a contoured weld of the contoured object. A tooling assembly is configured to carry out the method.

A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.

A method is provided for joining a plurality of workpiece parts, in particular body parts, in which: a) the workpiece parts are inserted into a joining tool, b) the workpiece parts in the joining tool are monitored for damages, c) the workpiece parts are joined by the joining tool, and d) the joined workpiece is monitored for damages in the joining tool.
