Abstract
A heating embossing roll has a base surface on which a plurality of embossing portion is formed. An elongated material passes between the heating embossing roll and a heating flat roll so that the elongated material is pressed by the embossing portions of the heating embossing roll. The embossing portion is formed to have a height from the base surface that varies by section.
Claims7
A method for manufacturing a seat covering material, the method comprising a step of
- passing an elongated material between a heating embossing roll, which includes a plurality of embossing portions projecting from a base surface, and a heating flat roll so that the elongated material is pressed by the embossing portions, wherein:
- (a) at least some embossing portions of the plurality of embossing portions are formed to have a height from the base surface of the heating embossing roll that varies by section, and the elongated material is pressed by the plurality of embossing portions;
- each embossing portion of the at least some embossing portions includes:
- (i) a long-side surface and a short-side surface, which extend from the base surface, the long-side surface extending a longer distance from the base surface than the short-side surface;
- (ii) a top surface formed on a section that is farthest from the base surface;
- and
- (iii) a bevel formed between the top surface and the short-side surface, wherein
- the bevel varies in height from the base surface;
- (b) the at least some embossing portions include a group of embossing portions arranged along an imaginary line on the base surface, the imaginary line being oriented in the axial direction of the heating embossing roll;
- (c) the bevels of adjacent embossing portions in the group of embossing portions are inclined in different orientations with respect to the imaginary line;
- and
- (d) the plurality of embossing portions have the same height from the base surface to the top surface of each embossing portion in the plurality of embossing portions.
