Abstract:
1. A strapping device for strapping packaged goods with a wrapping strap, comprising: a tensioner for applying a strap tension to a loop of wrapping strap, the tensioner having a rotationally drivable tensioning wheel and a tensioning rocker that pivots relative to the tensioning wheel and engages with the tensioning wheel, wherein said tensioning rocker includes a grooved recess having a lower flat surface, wherein a tensioning plate having a lower convex curvature contact surface is attached to the tensioning rocker by a fastener passing through a bottom of the tensioning rocker such that the tensioning plate is pivotably disposed in said grooved recess of the tensioning rocker, such that at least part of the lower convex curvature contact surface of the tensioning plate abuts the lower flat surface of the grooved recess, such that a variation in the relative position of the tensioning plate longitudinally in relation to the tensioning wheel can be produced, and such that the tensioning plate is longitudinally movable in at least one direction relative to the tensioning rocker, and wherein a distance between the tensioning plate and the tensioning wheel can be varied to apply a tensile force on the wrapping strap; and a connector including a friction welding element for producing a friction weld connection at two areas of the wrapping strap disposed one on top of the other.
