    • In combination with a sliver coiler and can changer apparatus, a sliver compactor and severing device is provided which concurrently compacts coiled sliver and separates, parts or severs through attenuation the ultimate strand portion extending between the filled sliver can and the coiler. The combination is provided with control means which coordinates the elements to stop can filling upon sensing that a predetermined amount of sliver has been delivered to the can, to exchange the filled can for an empty one beneath the coiler and position the filled can beneath the compactor plate or ram of the means, to compact the sliver at a specified rate wherein sliver disruption is avoided while, through a safety shroud, covering the space between the can rim and the compactor spectacle plate, to restart sliver coiling in the empty can while maintaining compaction of the sliver in the filled can, and then to withdraw the plate from the filled can at a predetermined time prior to completion of filling the second and formerly empty can.
    • 与纱线卷取机和罐式变换器装置相结合,提供了一种条子压实机和切割装置,其同时压缩卷绕的条子并通过减弱在填充的条子罐与卷取机之间延伸的极限线条部分而分离,部件或切割。 该组合设置有控制装置,该控制装置在检测到预定量的条子已经被传送到罐子上时,协调这些元件以停止罐头填充,以将填充的罐更换成在卷取机之下的空的罐,并将填充的罐定位在压实机下方 平板或压头,以规定的速度压紧条子,避免条子破裂,同时通过安全罩覆盖罐边缘和压实机眼镜板之间的空间,以重新启动在空罐中的条子盘绕,同时保持 在填充罐中的条子的压实,然后在填充第二和以前的空罐之前的预定时间从填充罐中取出板。

    • Moulding flask adapted to be used in a process for forming a mould comprising steps of disposing, at the opening of the moulding flask, a pattern having a shield membrane of synthetic resin on the outer surface thereof, filling the space defined between the moulding flask and the pattern with particulate filler material such as sand, and applying negative pressure to the filler material so that the filler material is subjected to an external pressure to make a mould, said moulding flask having at least one surface on an intermediate partition surface formed by an impervious resilient membrane which is supported by a support member whereby, when the filler material is subjected to the negative pressure, the external pressure is applied to the resilient membrance which then presses the filler material so as to enhance compacting of the mould thus producing a strong and precise casting mould.
    • 适于用于成形模具的成形烧瓶包括以下步骤:在模型烧瓶的开口处设置在其外表面上具有合成树脂屏蔽膜的图案,填充模型瓶和 具有诸如砂等颗粒填料的图案,并且向填充材料施加负压,使得填充材料经受外部压力以制成模具,所述模制烧瓶在由中间分隔表面形成的至少一个表面上形成 不透水的弹性膜,其由支撑构件支撑,由此当填充材料承受负压时,将外部压力施加到弹性膜上,弹性膜然后挤压填充材料,以便增强模具的压实,从而产生强的 和精密铸模。
