Claim:
A method for producing a supporting web with a plurality of molded elements from a definable amount of plastic material, comprising the steps of: supplying moldable plastic material directly from an extruder to a molding tool and into mold cavities in the molding tool to form mushroom-shaped fasteners on a supporting web with each fastener having a head part, a stalk connected to the head part at one end thereof and a foot part at an opposite end of the stalk connected to the supporting web; and applying a negative pressure to at least some of the mold cavities so that the plastic material is moved onto mold walls of the respective mold cavities and fastener cavities are formed in the respective fasteners simultaneously with fastener formation from the plastic material of the extruder, each of the fastener cavities being rotationally symmetrical inside the respective fastener and extending from the respective foot part through the respective stalk at least as far as the respective head part.
