Various embodiments of the present disclosure provide a strapping machine strap-tensioning assembly with a self-energizing tensioning wheel and features that enable adjustment of the strap-tensioning assemblies for use with different strap sizes.

Strap-tensioning assembly with self-energizing transitioning wheel, and strap-size-adjustment features

Various embodiments of the present disclosure provide a strapping machine strap-feeding assembly with features that enable adjustment of the strap-feeding assembly to accommodate different strap sizes.

Strap-feeding assembly with strap-size-adjustment features

The present disclosure relates to a strapping head of a strapping device for strapping packaged goods with a strap. The strapping head includes an advancing apparatus and tensioning apparatus having at most three rollers for transferring an advancing motion, a retracting motion, and a tensioning motion to the strap. A least one of the wheels is operatively connected to a driving apparatus to cause the at least one of the wheels to rotate about a rotational axis for the advancing, retracting, and tensioning motions. The rollers can be brought in contact with the strap in pairs on both sides of the strap in different combinations with each other.

Strapping apparatus

The present disclosure relates to a strapping apparatus of a strapping device for strapping packed goods with a strap. The strapping apparatus includes a strap-advancing apparatus for advancing the strap during the formation of a strap loop, a strap-retracting apparatus for retracting the strap after the strap loop has been formed to bring the strap in contact with the packaged goods, and a tensioning apparatus configured to increase a strap tension of the strap lying against the packed goods. The problem addressed by the present disclosure is improving said strapping apparatus to the effect that the strapping head can be made as compact as possible. This problem is solved in that only one common motor drives the rollers of the strap-advancing apparatus, the strap-retracting apparatus, and the tensioning apparatus.

The present disclosure relates to a tensioning device of a strapping device for strapping packaged material with a strap. The tensioning device includes a tensioning wheel operatively connectable to a drive device to rotate the tensioning wheel about a rotational axis. The tensioning wheel has a circumferential surface configured to engage the strap. The tensioning device also includes a movable spacer provided on the tensioning wheel in the region of the circumferential surface of the tensioning wheel. The spacer is movable between a first position in which part of the spacer is a first distance from the rotational axis and a second position in which the part of the spacer is a second different distance from the rotational axis. The spacer projects beyond the circumferential surface of the tensioning wheel in at least one of the positions.
