A web is transported on a table crossed by a needle holder bar in which a row of needles is mounted for movement between retracted and advanced positions. Selected needles of the row are locked in the advanced position by control means of the Jacquard machine type. When the table with the web is moved toward the needles, the selected locked needles penetrate the web, forming depressed portions in the same, while the non-selected freely movable needles are pushed back by the web to retracted positions. After each step of the web, a row of depressed and non-depressed portions is formed so that the depressed portions form a depressed pattern on the web.
