  • Patent number: 11449646
    Abstract: A method is provided for the creation of an addendum for use in the design and production of sheet metal formed components, which method uses a sectionless approach. In a preferred approach, elevation curve (EC) lines are established relating to the component (ECc) and binder (ECb), and it is these lines which are used to design the addendum. Additional EC lines (EC1, EC2, EC3, etc.) can be added to modify or optimize the addendum design. The spaces between the EC lines are filled using various parameterized filling techniques so as to provide the addendum design. Optimization of the addendum can be achieved by modification of the various EC lines, so as to modify or control the various design parameters, in accordance with various quality or design criteria.

  • Patent number: 11440308
    Abstract: The present invention relates to a movable laminator and a plastic flooring laminating device applied by same. A laminating mechanism, a driving mechanism and a conveying mechanism assembled on a rack compose the laminator which can make continuous reciprocating movements. The movable laminator is then disposed in an automatic production line for plastic flooring to cooperate with an extruder, a rolling unit and a drawing mechanism to laminate a plastic flooring material composed of a substrate layer, a printed layer and a wear-resisting layer into a finished plastic flooring product in an automatic operation manner. Because the time of the lamination of the material by the movable laminator can match the speed at which the material is conveyed and moved, the laminating mechanism is driven by the second power source to move from the front section position to the rear section position on the rack.
