3. Spiral Accumulator
This machine is used between the shearing welding machine and the mainframe (forming sizing machine). Its function is to run out of the previous strip, and the next strip is prepared from the continuous production of the main machine (forming sizing machine) is ensured within a time and sufficient strip steel is stored.
This machine is mainly composed of feeding guide roller frame, clamp feeding device, looper body assembly, discharging device and electrical control device.

PART 2: Weld seam guide and the squeeze roll stand, welding bead cutter
Squeezing roller is to squeeze the edge of the tube which has been heated to welding temperature, by squeezing rolls giving a certain pressure to achieve welding purpose. Welding bead cutter is used to scrap weld seam and remove external burr. It is made up of two cutters for using alternately. If one is damaged, the other one will take the place to scrap. Scrapers can be adjusted and have the quick lift function by cam. There are two supporting roller underneath knife rest, in order to bear the overdraft of scraping.and after the bead cutter with one horizontal stand for polishing.
