    • A single or multi-orifice metal nozzle structure suitable for use in an ink jet printing system. The metallic nozzle member has at least one orifice extending therethrough, the orifice including a cylindrical portion, adjacent the outlet face of said nozzle, having a height ranging from 0.25 to 5 times its diameter and at least one frustoconical section divergent toward the face opposite the outlet face and communicating with the cylindrical portion. Where the metal nozzle is a multi-orifice metal nozzle, each frustoconical section communicates with a groove disposed in the face opposite the outlet face. The multi-orifice metal nozzle is prepared by grooving a metal plate with at least one groove, punching a plurality of frustoconical sections into the groove member and then forming a cylindrical portion into each frustoconical section and through the plate member.
    • 适用于喷墨打印系统的单孔或多孔金属喷嘴结构。 金属喷嘴构件具有延伸穿过其中的至少一个孔口,孔口包括邻近所述喷嘴的出口面的圆柱形部分,其高度为其直径的0.25至5倍,并且至少一个截头圆锥形部分朝向与 出口面并与圆筒部连通。 在金属喷嘴是多孔金属喷嘴的情况下,每个截头圆锥形部分与设置在与出口面相对的面中的凹槽连通。 多孔金属喷嘴通过用至少一个槽切割金属板,将多个截头圆锥形部分冲压到槽构件中,然后在每个截头圆锥形部分中并通过板构件形成圆柱形部分来制备。

    • Method and apparatus for crimping a round tenon for furniture manufacture, utilizing a crimping roll cluster consisting of a knurled drive roll and two idler compressing rolls. The apparatus includes means for feeding a wooden workpiece into and out of axial alignment with the crimping roll cluster; means for pressing the wooden workpiece into engagement with the knurled portion of the drive roll; means for rotating the workpiece from one to two revolutions, thus forming flutes into the tenon; and means for discharging the workpiece from the apparatus.Also disclosed is a method and apparatus for fluting a workpiece having tenons on both ends.
    • 用于压制圆形榫头用于家具制造的方法和装置,利用由滚花驱动辊和两个惰轮压缩辊组成的卷曲辊组。 该装置包括用于将木制工件进给到压接辊簇的轴向对准的装置; 用于将木制工件压紧到驱动辊的滚花部分上的装置; 用于将工件从一转至两转的装置,从而将槽纹形成榫头; 以及用于从工具排出工件的装置。 还公开了一种在两端上具有榫头的工件的凹槽的方法和装置。
