Automatic bundling tool device

A bundling tool device configured for bundling a bundling good with a one-piece-tie (OPT) and configured for automatically tightening the OPT, the bundling tool device comprising:

• a tightening mechanism with a tightening gear unit with a tightening gear, and with a tightening roller unit with two tightening rollers, forming a gap in between tightening gear and tightening rollers, where the gap is configured to hold a strap of a respective OPT processed by the bundling tool device, and the tightening gear of the tightening gear unit comprises teeth which are configured to fit into a serration of the strap,
• wherein the tightening roller unit comprises the two tightening rollers with respective individual adjustment elements configured to adjust their respective distance to the tightening gear, and thus a width of the gap, and
• wherein the tightening mechanism comprises a motor for automatically adjusting at least one of:
• a position of the tightening rollers relative to the tightening gear in response to a control signal of a control unit;
• or
• a minimal distance of the tightening rollers to the tightening gear in response to a corresponding control signal.
