Battery powered tensioning tool for strap

A tensioner for strap having an automatic tensioning cycle, comprising:

• a housing;
• a power supply removably mounted to the housing;
• a motor positioned in the housing;
• a tension head mounted to the housing, the tension head having a tension wheel operably connected to the motor;
• a nosepiece biasedly mounted to the tension head for movement relative to the tension head between an open state and a closed state, the nosepiece including a pinch wheel;
• a controller positioned in the housing;
• a home position switch operably connected to the controller, the home position switch configured for determining when the nosepiece is in the closed state;
• and
• a strap sensor located in the tension head and operably connected to the controller and positioned to sense the presence and/or absence of strap between the tension wheel and the pinch wheel;
• wherein in the automatic tensioning cycle, when the nosepiece is in the closed state, the home position switch generates a signal to the controller to reset the controller, and when the nosepiece is moved from the closed state to the open state, the home position switch generates a signal to the controller to allow actuation of the motor when the strap sensor senses the presence of strap between the tension wheel and the pinch wheel.

A tensioner for strap, comprising:

• a housing;
• a local power supply removably mounted to the housing;
• a motor mounted in the housing;
• a tension head mounted to the housing;
• a tension wheel positioned in the tension head, the tension wheel operably connected to the motor;
• a nosepiece operably mounted to the tension head for movement relative to the tension wheel between an open state and a closed state, the nosepiece including a pinch element, the nosepiece being biasedly mounted to bias the pinch element toward the tension wheel;
• an actuator handle operably connected to the nosepiece to move the pinch element toward and away from the tension wheel;
• a controller mounted in the housing;
• a home position switch operably connected to the controller, the home position switch configured for determining when the nosepiece is in the closed state;
• and
• a strap sensor operably connected to the controller and positioned to sense the presence and/or absence of strap between the tension wheel and the pinch element,
• wherein the nosepiece is moved away from the tension head to introduce strap between the tension wheel and the pinch element.
