Abstract: A blow tube for delivering particulate material from a container thereof to a mold to form a core has a unitary, elongate body formed of resiliently elastic material which enables the body to adjust and compensate for misalignment of the container and the mold. The blow tube body has a bore having a plurality of axially spaced sections so that when the particulate material is blown through the body by compressed gas, the density of the particulate material is increased and the velocity of the gas and particle stream is increased. The elasticity of the blow tube body enables the latter to expand in the event the particulate material clogs the blow tube, thereby enabling the clog to disaglomerate.

Abstract translation: 用于将颗粒材料从其容器输送到模具以形成芯的吹管具有由弹性弹性材料形成的整体细长体，其使得主体能够调节和补偿容器和模具的未对准。 吹管主体具有多个轴向间隔开的孔，使得当颗粒材料通过压缩气体吹过主体时，颗粒材料的密度增加并且气体和颗粒流的速度增加。 吹塑管体的弹性使得后者能够在颗粒材料阻塞吹塑管的情况下膨胀，从而使堵塞物团聚。
