An upholstery layer of a vehicle interior panel includes an airbag tear seam formed as a plurality of blind cuts arranged along a tear seam pattern. Each one of the blind cuts is formed by laser material removal at a plurality of locations along the pattern. Laser energy is delivered to the upholstery layer in a series of ultra-short pulses to form the blind cuts, which are formed in the upholstery layer while separate from a substrate of the panel. This technique is particularly useful with leather upholstery materials, in which non-visible airbag tear seams have been proven difficult to form.

A perforation system and method of perforating a flexible work piece. The perforation system includes a punch tool having at least one punch head defining a vertical axis. The punch head has a first shape. A die is positioned along the vertical axis and includes an ejection port having a second shape. The first shape overlaps the second shape to provide for punch-to-die contact that results in a clean cut along a perimeter of the second shape.

An artificial intelligence-based leather inspection method and leather product production method includes the step of using sensor means to obtain a leather data of a leather raw material, then the step of inputting the leather data to an artificial intelligence module to determine a defective area and a non-defective area of the leather raw material, the step of establishing an area data after judgment of the defective area and the non-defective area and then using the area data to define the non-defective area into one or multiple reserved areas so that the leather raw material can be cut into leather components corresponding to the respective reserved areas.

A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.

A multi-layered material that includes a layer of natural leather or collagen leather with holes and/or micro-holes and coated with a hydrophobic agent, which is superimposed and adhered, by means of hydrolysis-resistant adhesives, said adhesives being arranged in a non-laminar fashion, to a layer of waterproof, breathable material to prevent the passage of water and to allow the passage of air therethrough.

According to one aspect of the present invention, provided is a method of attaching an emblem to a vehicle seat, the method including providing a seat and an emblem, the seat having an outer surface on which a coating layer is formed, removing the coating layer to correspond to an edge of the emblem, aligning the emblem with the seat to correspond to a portion in which the coating layer is removed, and attaching the emblem to the seat by pressing the emblem using a mold unit and applying a high-frequency current.

A seat trim cover for an automotive seat formed from milled leather which lacks coatings and/or paint on the milled leather while retaining stored elongation introduced to the leather fiber structure during a milling process. At least one coating and/or paint is applied to an upper surface of the 3-dimensional leather shape after the milled leather is formed into a 3-dimensional leather shape by one or more of a vacuum form process, a compression mold process, and/or an embossing process.

The present invention discloses a flexible leather slice blanking apparatus and an implementation method. The apparatus comprises a working tab e, a projector, an industrial camera, an installing support, a manipulator, a matrix chuck fixture and a base. The installing support is arranged on the working table and disposed in a corresponding range of a cutting region behind a numerical-control leather cutting machine. The projector and the industrial camera are respectively arranged on the installing support. The manipulator is installed on the base. The matrix chuck fixture is located above the manipulator and connected with the manipulator through a matrix chuck fixture installing frame. The blanking apparatus provided by the present invention is low in labor cost and high in efficiency; and moreover, leather slices can be classified and collected, thereby saving labor force and increasing production efficiency.
