COURSE AUTOMATIC CHANGER FOR NEWSPAPER SHEET STRETCH GUIDE DEVICE

摘要

PURPOSE:To easily change a course by providing two coupling sections concurrently and removably coupled with the connecting pieces of guide belts of a course change portion respectively at the tip section of a conveying piece so that the coupling sections are coupled with the connecting pieces in the running direction of the guide belts and released in the opposite direction. CONSTITUTION:A newspaper sheet is guided to a course change portion 6 while the connecting piece 3 of a basic course guide belt 1 is coupled with one coupling section 50 of a conveying piece 5 fitted at the tip section of the newspaper sheet Po. When the basic course guide belt is stopped running or decelerated and a change course guide belt 2 is started running, the connecting piece 4 of the change course guide belt 2 waiting at the foreground position from the course change portion is coupled with the other coupling section 51 of the conveying piece 5 at the course change portion by the relative speed change between both guide belts 1 and 2, then the conveying piece 5 is released from the connecting piece 3 of the basic course guide belt 1 having been coupled so far, and the course of the newspaper sheet is changed.
