摘要
In folding boxes forming a conveyor chain, rectangular, tubular carton blanks are introduced stepwise into two juxtaposed mirror-image designed folding stations. In the folding stations, the carton blanks are defomed by means of fingers and clamps so that their base surface is pulled into a parallelogram. The two edges forming the longer diagonal are pressed by means of stamping dies and by means of a counterholder and a stamping plate, respectively. After pressing, the carton blanks are pulled back into the folding boxes and are returned to their rectangular shape.
