Abstract

PURPOSE: To perform the necessary action of the indication, display, removal, etc. of the abnormal locations of the wound raw materials of a printing machine, etc. accurately and freely, by detecting said abnormal locations at a feed portion before working, and by generating signals after the meterials pass over arbitrary distance.
CONSTITUTION: Abnormality in case of the production of wound raw materials 1, such as, a web, etc. and the joining portions with new raw materials are detected at a material feed portion by means of a detector 4, input to a main machine B as signals V, amplified 7 and changed into start signals 8 for detecting timing. The carrying speed V of the raw materials 1 is detected 6, operation is started by the speed change ΔV and the start signals for detecting timing, and time that puts out signals for displaying the presence of abnormal locations and for removing the abnormal locations is decided at a point of time when the materials move up to a spot located at arbitrary distance L from the detecting portion 4.
