Abstract
A strapping machine includes a machine body with a package-strapping space. A strap is fed to the package-strapping space. A spring-loaded swing arm is pivoted to the machine body, and is associated with a rotating shaft via a cam unit such that rotation of the shaft results in turning of the swing arm relative to the machine body. An electrically operated clamp unit is mounted movably on the swing arm, and is movable relative to a strap passage in the swing arm. A delay circuit is electrically coupled to a detecting device and the clamp unit. When the detecting device detects a first position of the swing arm, the delay circuit will actuate the clamp unit to move from a releasing position to a clamping position after a preset delay time. When the detecting device detects a second position of the swing arm, the clamp unit is immediately actuated to move from the clamping position to the releasing position.
