AI Technical Summary
Technical Problem
Existing strapping devices face challenges in efficiently tensioning and sealing straps around loads, particularly in ensuring consistent friction welding to form a secure tensioned strap loop.
Method used
The strapping device incorporates a support, a weld plate, a motor, a weld arm, and a cam mechanism that allows the weld arm to move between home and sealing positions, enabling precise tensioning and friction welding of strap layers.
Benefits of technology
This configuration ensures effective tensioning and sealing of straps, forming a secure tensioned strap loop around loads, while also allowing for continuous rotation of the ring gear without damaging the transmission.

Abstract
Various embodiments of the present disclosure provide a strapping device including a weld plate; a motor; a weld arm comprising a weld pad and movable between a weld-arm home position and a sealing position; a link movable from a first position to a second position to cause the weld arm to move from the weld-arm home position to the sealing position; a cam engager supported by the link and movable between a cam-engager home position and an actuated position; and a cam configured such that rotation of the cam in one direction causes the cam engager to move from the cam-engager home position to the actuated position and rotation of the cam in the other direction causes the link to move from the first position to the second position to cause the weld arm to move from the weld-arm home position to the sealing position.
