A mechanism for use in a strapping apparatus including a pair of like rolls which have meshing gears as flanges and which are rotated by a drive means through a clutch system to both feed and tension strap without stopping or reversing the drive means. Strap is laced about and nipped by the rolls and, as the rolls rotate at the same speed and the roll flanges travel with the strap, abrasion along the strap sides and edges is avoided.

In a strapping apparatus, a strap feed and tension mechanism including a pair of rolls having peripheral surfaces of substantially like diameter for engaging with opposite sides of a strap, a pair of meshing gears fixed to each of said rolls as flanges on opposite sides thereof, and drive means for rotating one of said rolls, said meshing gears serving as strap guides and also causing said pair of rolls to rotate at substantially the same speed during strap feeding and tensioning to thereby avoid abrasion of the strap.
