Apparatus for detecting displacements and/or presence of sliver in a fiber processing machine |
摘要 |
A fiber processing machine includes an arrangement for forwarding a sliver through a space in an advancing direction; an arrangement for continuously displacing the sliver in the space transversely to the advancing direction while the sliver is forwarded in the advancing direction; and an apparatus for detecting a presence, absence, motion or standstill of a sliver. The apparatus includes a transmitter emitting a sensor beam passing through the space transversely to advancing direction for being intermittently interrupted by the sliver during displacement thereof transversely to the advancing direction; and a receiver positioned in a path of the sensor beam for receiving a light or a dark signal dependent whether or not the sensor beam is interrupted by the sliver during displacement thereof transversely to the advancing direction.
