Abstract
A method for manufacturing egg timer-shaped absorbent pads in which an absorbent material continuous strip of uniform thickness and uniform width is feed along a longitudinal path and divided in the longitudinal direction, along a continuous wavy cutting line extending symmetrically relative to the median line of the strip, into two partial strips of periodically variable width having one straight edge on and opposite wavy edge, and are offset relative to each other and superimposed, one on the other, to form a composite strip having opposite hourglass-shaped edges and a central part having a thickness twice that of the opposite edges and cutting such superimposed, composite strip in the transverse direction in the zones of maximum width.
