A pattern sheet has a bar pattern comprising a plurality of parallel rows of bars, the bars in adjoining rows preferably being mutually offset in the longitudinal direction. The pattern sheet is intended for use in the making of a panel to be cut into floor boards with n + 1 rows of bars having essentially the same width, n being 2, 3, 4.... Over essentially its entire width, the bar pattern is designed in such manner that the bars in every n:th row are substantially twice as wide as the bars in the other rows. |
