Abstract:
1. A sheet having fastening elements, comprising a base strip and at least one fastening element made from said base strip, said fastening element comprising a stem part and a head part protruding laterally from said stem part in a left CD transverse direction; in a right CD transverse direction and in a MD longitudinal direction, perpendicular to said left and right CD transverse directions, said head part having a left Pb point being the point of the head which is the most remote from the stem in the left transverse direction and a left Ph point which is the first point of a lower surface of the head facing said base strip and leaving the stem towards said left Pb point; a right Pb point being the point of the head which is the most remote from the stem in the right transverse direction and a right Ph point which is the first point of a lower surface of the head facing said base strip and leaving the stem towards said right Pb point; and a rear Pb point being the point of the head which is the most remote from the stem in the MD longitudinal direction and a rear Ph point which is the first point of a lower surface of the head facing said base strip and leaving the stem towards said rear Pb point, a fastening angle the greatest to the left being the angle made between a left straight line, extending from said left Ph point to said left Pb point, and the left CD transverse direction; a fastening angle the greatest to the right being the angle made between a right straight line, extending from said right Ph point to said right Pb point, and the right CD transverse direction; a fastening angle the greatest to the rear being the angle made between a rear straight line, extending from said rear Ph point to said rear Pb point, and the MD longitudinal direction; and wherein said rear Ph point is different from said rear Pb point, and said fastening angle the greatest to the rear is smaller than said fastening angle the greatest to the right and smaller than said fastening angle the greatest to the left.
