Abstract
An arrangement for trimming short shavings from a seam inside a longitudinally welded pipe having a longitudinal axis, in which an inside shaving is scraped off continuously with a stationary blade by moving the pipe relative to the blade. The inside shaving is then cut up discontinuously with an actuated knife inside the pipe. The scraping procedure is carried out with scraping forces having a resultant force vector lying substantially in a plane through the longitudinal axis of the pipe and the seam. The scraping procedure is dependent on the speed of the moving pipe, whereas the cutting procedure is independent of the speed of the moving pipe.
