    • A flat elongated substrate having a bead of a gas and/or moisture pervious adhesive having a desiccant is moved along a predetermined linear path between spaced upper wheels aligned with spaced lower wheels. The upper wheels have a peripheral groove to shape the bead as the substrate moves between the upper and lower wheels. The lower wheels each have a U shape peripheral groove with the base of the U of the downstream wheels being narrower than the base of the U of the upstream wheels and the depth of the U of the downstream wheels being deeper than the depth of the U of the upstream wheels to provide a spacer stock having a base connected to a pair of spaced upright legs such that the base connected to the legs have a generally U shape configuration and a shaped bead on the surface of the base between the legs. The spacer stock may be bent to form a spacer frame to separate outer sheets of an insulating glazing unit.
    • 具有具有干燥剂的气体和/或湿气可渗透粘合剂的珠粒的平坦细长基材沿着与间隔开的下轮对准的间隔开的上轮之间的预定线性路径移动。 当上基轮在上轮和下轮之间移动时,上轮具有周边凹槽以使胎圈成形。 下轮各具有U形周向槽,下游轮的U的底部比上游轮的U的底部窄,并且下游轮的U的深度比U的深度更深 的上游轮以提供间隔件,其具有连接到一对间隔开的直立腿的基部,使得连接到腿的基部具有大致U形构造,并且在腿之间的基部的表面上具有成形的凸缘。 间隔件坯料可以被弯曲以形成间隔框架以分离绝缘玻璃窗单元的外部片材。
