ABSTRACT:
A plurality of molded surface fasteners, each having a substrate sheet and a multiplicity of hook elements, are connected to one another via a sheet-like connector embedded in the individual substrate sheets over their entire area. In production, a die wheel having a plurality of male-engaging-element-forming cavity groups, which are formed by dividing a plurality of axially arranged rows of cavities with a number of circumferential predetermined-width cavity-free areas disposed therebetween, said cavity groups being for molding the plurality of male engaging elements circumferentially on said die wheel is rotated in one direction, a predetermined width of molten resin is continuously injected from an injection die toward said male-engaging-element-forming cavity groups of said die wheel, a sheet-like connector having adequate open spaces through which said molten resin is to be passed is continuously introduced circumferentially of said die wheel during said injecting, and the circumferential surface of said die wheel are positively cooled.
