Automatic bundling tool device

An automatic bundling tool device (ABT) for bundling a bundle good with a one-piece-tie (OPT) including a one-piece-tie (OPT) band part end and a one-piece-tie (OPT) head part, the ABT comprising:

• a guiding device defining a path configured to guide the OPT band part end around the bundle good through a window in the OPT head part;
• a tensioning device comprising a gear wheel configured to engage the OPT band part end and configured to tension the OPT, with a pulling of the OPT band part end that is guided through the window in a tensioning direction, the tensioning device further configured to push the OPT band part end against the tensioning direction in a pushing direction after the OPT has been tensioned;
• and
• a control device configured to determine a force or other characteristic parameter for the pushing of the OPT band part end against the tensioning direction and output a quality check signal as a function of the force or the other characteristic parameter and a reference force or reference value predetermined for the force or the other characteristic parameter.
