| 20120060703 | BAND CLAMP TENSIONING TOOL - A system for protecting tubes in a heat recovery system is provided. Such tubes are often protected by shielding that is attached thereto the tubes by a plurality of band clamps. Each band clamp is associated with a guard that protects the same from the hot gases traveling through the field of tubes. In addition, an automated tool is provided for tensioning the bands about the shields. The automated tool allows the band clamps to be properly interconnected to the shields in a preferred manner. | 03-15-2012 |
| 20130014653 | Feeding and Reversing Mechanism for a Strapping MachineAANM Lai; Chien-FaAACI Taichung CityAACO TWAAGP Lai; Chien-Fa Taichung City TW - A feeding and reversing mechanism for a strapping machine includes a forward-reverse wheel assembly and a tension wheel assembly which are mounted on a base and arranged in such a way to provide larger contact areas between a strapping band and the two wheel assemblies. The feeding and reversing mechanism further includes first and second spring units. The first spring unit helps to keep a suitable gap between an active wheel and a passive wheel of the tension wheel assembly for the strapping band to pass through. The second spring unit helps to move the passive wheel toward the active wheel of the tension wheel assembly, so that the strapping band can be clamped between the passive wheel and the active wheel tightly to facilitate reversing and tightening of the strapping band. | 01-17-2013 |
| 20130014654 | Reverse Tension Mechanism for a Strapping MachineAANM Lai; Chien-FaAACI Taichung CityAACO TWAAGP Lai; Chien-Fa Taichung City TW - A reverse tension mechanism for a strapping machine includes an active wheel, a supporting arm installed with a passive wheel, a lever, and a spring. The supporting arm can be moved relative to the active wheel so that a strapping band which passes through between the passive wheel and the active wheel is clamped to control retracting and tightening of the strapping band. A first end of the lever is pivotably connected to a section of the supporting arm, and the spring is vertically installed between a second end of the lever and the section of the supporting arm. The first end of the lever can be activated by a cam to press the spring vertically to produce pushing force to swing the supporting arm. | 01-17-2013 |
| 20130284033 | TENSION HEAD FOR MODULAR STEEL STRAPPING MACHINE - A self-actuating tension head for a strapping machine includes a body defining a strap path, a drive wheel, a tension wheel a fixed distance from the drive wheel and a pinch wheel. The strap path extends between the tension and pinch wheels. A first link operably connects the drive and tension wheels and defines a first pivot arm that is pivotable about the drive wheel axis of rotation. A second link operably connects the tension and pinch wheels and defines a second pivot arm that is pivotable about the pinch wheel axis and movable along the second pivot arm to move the tension wheel into and out of engagement with the pinch wheel. The first and second pivot arms define an energizing angle therebetween that decreases as the tension wheel is moved into engagement with the pinch wheel and increases as the tension wheel is moved out of engagement with the pinch wheel. | 10-31-2013 |
| 20140060345 | BATTERY POWERED TENSIONING TOOL FOR STRAP - A tensioner for strap includes a housing, a battery, a motor, a tension head having a tension wheel operably connected to the motor and a nosepiece having a pinch element. The nosepiece is mounted to the tension head for movement relative thereto. An actuator handle is mounted to the nosepiece to move the pinch element toward and away from the tension wheel. A strap sensor is operably connected to a controller and senses the presence or absence of strap between the tension wheel and the pinch element. A home position switch senses pinch wheel proximity to the tension wheel. The nosepiece is moved away from the tension head to introduce strap to the tool and the home position switch changes state to signal the controller to permit actuation of the motor when the strap sensor senses the presence of strap between the pinch element and the tension wheel. | 03-06-2014 |
| 20140311363 | STRAPPING APPARATUS - A strapping apparatus for strapping a tensioning strap around a packaging item includes a frictional wheel that operates against a support to tighten the tensioning strap. The frictional wheel is operatively connected to a drive unit and can be lifted from the support by a swiveling lever. The swiveling lever includes an interrupting element to interrupt the path of action between the frictional wheel and the drive unit so as to be able to lift the frictional wheel in an unloaded state from the tensioning strap. | 10-23-2014 |
