Abstract
1,241,084. Photo-electric investigation of running threads. W. REINERS. Jan.16, 1969 [Jan.20, 1968], No.2569/69. Heading G1A. The thickness of a running thread is measured by a photo-electric arrangement, the arrangement being such that while the thread is running it is kept pressed against the transparent cover 5 for the photo-cell 4 (position F 1 ), but if there is no movement in the longitudinal direction e.g. during insertion of the thread or when the thread has stopped, the tension on the thread is relaxed and it abuts against the end of prism 3 (position F 2 ), where it is held by air suction tubes 6, 7. In this latter position (F 2 ) the shadow of the thread thrown by light from at least two directions towards the photo-cell surface either falls outside the sensitive area of the cell or is minimal compared with the shadow for the thread in position F 1 and so a measurement signal is not produced. Instead of a single light source 1, a number of sources may be provided to give light beams falling on the thread from various directions. Instead of prism 3, a diffusing plate may be provided.
