Abstract

See full text

Two strip materials from which portions may be severed and used together as a releasably engageable fastener. Each strip material comprises a bonding layer in which are embedded a plurality of U-shaped monofilaments. Each U-shaped monofilament includes two headed stem portions adapted to engage the headed stem portions of the other strip material, and the monofilaments are rectangularly arrayed, and spaced to provide a number of headed stem portions per unit length that are different from and not a multiple of or evenly divisible by the number of headed stem portions per unit length on the other strip material in any direction so that upon engagement the rows of headed stem portions of one strip material cannot readily slip between the rows of headed stem portions on the other.
