FIELD: process engineering.
SUBSTANCE: proposed machine comprises fee assembly arranged between two feed drums. First spindle is arranged along first path of film feed to flow downstream of feed assembly towards first spindle and to be wound thereon. Second spindle is arranged along second path of film feed to flow downstream of feed assembly towards second spindle and to be wound thereon. Higher speed clamp assembly is arranged between two higher-speed drums located along film path wherein film moves from feed assembly to clamp assembly at higher speed and, then, along second film path while allows operating in intermittent and continuous modes. Bag pile winding assembly allows film motion along first or second selected path and comprises set of rods crossing film part at, least, two points and arranged to displace in first and second film paths.
EFFECT: higher operating speeds.
