    Abstract: A trimmer apparatus for removing flash from the inner diameter opening and the peripheral surface of a molded diaphragm. A molded diaphragm is placed on a rotatable fixture secured in a turret. Upon activation of an electrical switch the fixture is rotated to a press member station. In this location the turret is held stationary to allow a retractible member to engage a die member under the diaphragm to remove the flash from the inner diameter. In response to an operation signal the retractible member is raised from the die member and the turret is indexed to a cutting member. The cutting member presses the peripheral surface of the diaphragm against the fixture and is guided by the external surface of the diaphragm to simultaneously remove the flash from the outer edge of a diaphragm while the press member is in operation.

    Abstract translation: 一种用于从模制隔膜的内径开口和外周表面去除闪光的修剪装置。 将模制隔膜放置在固定在转塔中的可旋转夹具上。 在启动电气开关时，固定装置旋转到压力构件工位。 在该位置，转台被固定以允许可伸缩构件与隔膜下方的模具构件接合以从内径移除闪光。 响应于操作信号，可伸缩构件从模具构件升高并且转台被分度到切割构件。 切割构件将隔膜的外周表面压靠在固定装置上，并且由隔膜的外表面引导，同时在按压构件运行时从隔膜的外边缘移除闪光。
