Abstract
Sheet having fastening elements, comprising a base strip made of thermoplastic material and at least one element made from the strip, the element consisting of a stem extending in a transverse, in particular vertical, direction to the plane of the base strip, and having a cross section which is substantially uniform or decreases from the base strip towards the apex of the stem, in particular as far as the apex of the stem, and a part forming a head which protrudes laterally from the apex of the stem.
Claims14
A method for manufacturing a sheet comprising a base strip and at least one fastening element made from one side of the strip, said fastening element comprising a stem part and a head part protruding laterally from the stem, comprising the steps in which:
- a preform sheet comprising said base strip and at least one preform element made from said one side of the strip, said preform element comprising a preform stem part and a preform head part protruding laterally from said preform stem part is passed into an interstice formed between a support surface and a pressing surface, wherein said preform head part protrudes laterally in a machine direction, more on a first machine direction side than on a second machine direction side, wherein said first machine direction side is opposite from said second machine direction side;
- said preform element being passed into said interstice such that said at least one preform element is deformed to obtain thus said sheet comprising said base strip and said at least one fastening element made from one side of the strip, said fastening element comprising a stem part and a head part protruding laterally from the stem in said machine direction, more on said second machine direction side than on said first machine direction side.
