Abstract:
1. A process for filling a vertically oriented tube with granular material, which material is guided downwardly into the tube, comprising the steps of: positioning a line into the tube having transverse flexible elements substantially perpendicular to the line and which have a radial dimension smaller than the inner diameter of the tube, providing a line take-up reel having a non-circular outer line take-up profile to which an upper end of the line is connected, and rotating the take-up reel to wind the line about the non-circular line take-up profile for lifting the line as the tube is filled with granular material with the non-circular line take-up profile imparting shocking movement and forces to the line for impeding the accumulation of granular material on the transverse flexible elements as the line is lifted by the rotating take-up reel for preventing the accumulation of granular material on the transverse flexible elements.
