摘要： The apparatus for manufacturing the ink jet glass tubes includes a vertical mandrel which receives the tubes one at a time from a feeder and rotates them relative to a pair of gas nozzles for their heating. The tube is heated in an axially limited intermediary zone so as to form an hour-glass shaped profile.The profile of the tube is scanned by a television camera which generates two signals indicative of the internal diameter. These are compared electronically with a stored indication of the desired diameter and the two nozzles are rotated into an inactive position when this diameter is reached. The tube is cut along a plane so as to make the profile of the nozzle coincident with a reference profile by a device including an optical device connected to a cutting wheel to permit comparison of the hour-glass profile of the element with the reference profile. The severed end of the tube is then lapped and covered with a non-wettable material. The tubular element is bonded within a piezo-electric transducer, by locating the latter partially in a chamber, after fitting it over the tubular element, while a pump draws an epoxy resin through the chamber and into the space between the transducer and the tubular element.
摘要翻译：用于制造喷墨玻璃管的装置包括垂直心轴，其从进料器一次接收管，并相对于一对用于加热的气体喷嘴旋转它们。管在轴向限制的中间区域中加热，以形成沙漏形状。管的轮廓由电视摄像机扫描，该摄像机产生指示内径的两个信号。这些电子与存储的所需直径的指示进行比较，并且当达到该直径时，两个喷嘴旋转到非活动位置。沿着平面切割管，以便通过包括连接到切割轮的光学装置的装置使得喷嘴的轮廓与参考轮廓一致，以允许将元件的沙漏轮廓与参考轮廓进行比较。然后将管的切断端重叠并覆盖有不可润湿的材料。管状元件通过将管状元件安装在管状元件上之后将其部分地安置在腔室中而将其连接在压电换能器内，同时泵将环氧树脂通过该腔室并进入换能器与管状元件之间的空间。

摘要： Mounted within a substantially hollow supporting and containing housing are tubes which communicate at one end with an ink reservoir and whose opposite ends are aligned with respective ink discharge nozzles provided in a plate member which faces the printing surface in use. The plate is mounted on the housing so as not to touch the ends of the tubes and with the interposition of yieldable sealing members. The tubes are mounted in the housing with the aid of a positioning tool the shape of which reproduces essentially the shape of the plate. A resin is subsequently poured into the housing and, after hardening, constitutes an elastic mass for retaining the tubes in the housing.
