20090013656 | Two-Piece Strapping Tool - A two-piece strapping tool having a manual tensioner and a battery-operated sealer is disclosed. The tensioner is a feedwheel tensioner that uses a serrated feedwheel to grip a first portion of the strap and a tension gripper to hold a second portion of the strap in a stationary position. The tensioner is configured to matingly receive the sealer between the tensioner's support legs such that the sealer may readily engage the overlapping portions of the strap to be welded. The sealer is battery-operated and uses a vibrational-type weld assembly driven by an electrical motor to weld overlapping portions of the strap. The sealer also includes a cutting assembly to sever the welded strap from a strap source. | 01-15-2009 |
20090188398 | STRAPPING TOOL - A strapping tool for tensioning a strap around a load, adhering the strap onto itself, and cutting a feed end of the strap, includes a body having a foot on which the strap is disposed during a strapping cycle. The body housing and/or forming a part of a tensioning element and including a welding element. One or more pneumatic motors tension the strap and drive the welding element. A pneumatic module is mounted to the body. The module has a compressed gas inlet to the module and is configured for controlling the flow of compressed gas to the one or more motors. A handle is mounted to the body and operably connected to the pneumatic module. The handle is configured for manipulating the tool and includes an actuator for permitting and isolating the flow of compressed gas to the pneumatic module. The handle is orientable so as to allow a user to select a desired handle orientation for operation of the strapping tool. At least one hold-down finger is mounted at about the foot to temporarily hold the strap on the foot during tool operation | 07-30-2009 |
20090241298 | PRE-CUT SEAL FOR STRAP - A seal has pre-cut slits formed in the seal body for securing the seal around a strap. The seal body has positioning tabs or a centering hole to position a hand tool to facilitate bending of the metal seal tabs defined by the pre-cut slits. The pre-cut seal is applied to overlapping sections of the strap and the seal tabs and strap ends are bent into an interlocking engagement sufficient to prevent withdrawal of the strap sections from the seal. A number of slits may be present in the seal depending on the size and shape of the seal, and the same number of slits may be formed on opposing sides of the seal. Different numbers of slits may also be formed, depending on the application. An inner surface of the seal may include a non-slip surface material such as grit or adhesive and/or may be formed with teeth or a knurled surface. | 10-01-2009 |
20120210682 | HAND-HELD STRAPPER - A strapping tool for tensioning and securing a strap on or around an object or load includes a motor, a tensioning assembly coupled to the motor, and a weld plate assembly coupled to the motor. The motor is actuated in a first direction to control the tensioning assembly to tension the strap during a tensioning operation and the motor is actuated in a second direction to control the weld plate assembly to weld the strap to itself during a welding operation. | 08-23-2012 |
20120295126 | CONTINUOUS STEEL STRAPPING SEALS - A strip of multiple seals, each seal for sealing around overlying courses of strapping material to form a seal of the strapping material onto itself at the overlying courses includes an elongated strip of ductile metal. The strip has a longitudinal direction having edges and defining a longitudinal axis parallel to the edges, and a transverse direction normal to the longitudinal axis. Each seal defines a respective transverse axis. The strip has a plurality of substantially identical slots formed in the transverse direction to define the respective seals. The slots extend toward, but not to, the edges of the strip and define connecting portions between ends of the slot and the respective edges. The slots are equally spaced from one another in a longitudinal direction to define the respective seals. | 11-22-2012 |
20130085053 | SEALING TOOL FOR STRAP - A tool for sealing overlying courses of a strap that includes a gripping unit, a power supply unit detachably affixed to one end of the gripping unit, and a motor in the gripping unit. A cam is coupled to the motor and a notching unit is coupled to the cam by a plurality of linkages. | 04-04-2013 |
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 |
20150321777 | REDUCED POWER CONSUMPTION SEALING TOOL FOR STRAP - A sealing tool for forming a joint in a seal positioned on overlying courses of strap includes a body, a motor and drive train housed, at least in part, in the body, a power supply and a sealing assembly mounted to the body. The sealing assembly is operably coupled to the motor. The sealing assembly includes at least one jaw having a pair of opposing jaw elements. Each jaw element has two edges for cutting into the seal and the courses of strap and forming a bent tab. The jaw element edges are configured to cut into the seal and the courses of strap material at different distances into a width of the seal and strap material. A method for forming seal and a seal formed by the tool and method are disclosed. | 11-12-2015 |
