A mandrel for transporting a hollow cylinder including an elongated arm, a dish shaped disk adjacent one end of the elongated arm, the dish shaped disk having a flexible lip flared inclined away from the elongated arm, the flared flexible lip having a circular outermost edge, and a reciprocable presser means adapted to partially flatten at least a portion of the flexible lip adjacent to and including the outermost edge of the lip toward the elongated arm to increase the length of the circumference of the circular outermost edge of the lip.
