Abstract
An easy-to-grip diaper fastener tab has an array of hook-shaped fastener elements arranged in parallel rows, each fastener element including a stem and a crook extending from the stem in a predetermined direction to a distal tip. The array includes a plurality of rows of fastener elements arranged such that, in each row, all of the crooks face in the same direction and parallel to the direction of the row, with the crooks of adjacent rows facing in opposite directions. The longitudinal spacing between opposing tips of adjacent hooks of adjacent rows is greater in a first portion of the array than the longitudinal spacing between opposing tips of adjacent hooks of adjacent rows in a second portion of the array, such that the crooks of the hooks of the first portion are more exposed for engaging loops than the crooks of the hooks of the second portion. Methods and molds for forming such arrays are also provided.
