    • A method of manufacturing a fastener product includes continuously introducing a sheet of preformed material to a gap defined adjacent a peripheral surface of a rotating mold roll. A lane of resin is also introduced into the gap with the lane overlapping a longitudinal edge of the sheet. The resin is pressed against the sheet in the gap, such that the resin becomes permanently bonded to the sheet, while an array of stems is molded from the resin in the thicker region, the stems extending from a base portion of the resin. Engageable heads are formed on the stems to form fastener elements. The gap is configured with a step in thickness, the step defining a boundary between a relatively thicker gap region and a relatively thinner gap region, the sheet of preformed material being introduced to the gap with its longitudinal edge disposed within the thicker gap region.
    • 制造紧固件产品的方法包括将预成型的材料片连续地引导到邻近旋转的模具辊的圆周表面限定的间隙。 树脂的通道也被引入到间隙中,该通道与片材的纵向边缘重叠。 树脂被压靠在间隙中的片材上,使得树脂永久地粘合到片材上,同时在更厚的区域中由树脂模制茎的阵列,茎从树脂的基部延伸。 可啮合头形成在杆上以形成紧固件元件。 该间隙被配置为具有厚度的台阶,所述台阶限定相对较厚的间隙区域和相对较薄的间隙区域之间的边界,所述预成型材料片材被引入所述间隙,其纵向边缘设置在较厚间隙区域内。
