Abstract

See full text

A strip material from which portions may be severed and used together as a releasably engageable fastener. The 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 another portion of the strip material. The U-shaped monofilaments are disposed in generally straight rows longitudinally of the strip material with a percentage of the center to center spacing dimensions between adjacent longitudinal rows being less than a maximum dimension equal to the diameter of the heads plus the diameter of the stems so that slippage of heads longitudinally of the strip material between these closely spaced rows will be restricted, and with the center to center spacing dimension between the rest of the adjacent rows being greater than the maximum dimension and being selected to help provide a desired level of engagement and disengagement forces between the portions. The U-shaped monofilmanets are also disposed in zig-zag rows transverse of the strip material and are spaced and shaped so that slippage of heads transversely of the strip material between the zig-zag rows will also be restricted and to help provide a desired level of engagement and disengagement forces between the portions. Thus, upon engagement the rows of headed stem portions of one portion of the strip material cannot readily slip between the rows of headed stem portions on another portion of the strip material.
