Abstract
A device for tensioning and securing the ends of packing straps which are pressed by a pressure plate against a tensioning wheel. The pressure plate is designed to be lifted off of the tension wheel by the operating lever thereby allowing rotation of the tensioning wheel via an actuator element, thus enabling insertion of the strap ends into the tensioning device. This arrangement makes a special release lever unnecessary.
Claims25
An apparatus for tensioning and securing together two sections of a packing strap comprising a tensioning wheel, a swivel lever, pressure plate means which cooperates with said tensioning wheel for selectively providing tension to the sections of said packing strap, closing means for pressing together and securing together said sections of said packing strap, and opening means for lifting said closing means from said sections of said packing strap and releasing the tension on said sections by said pressure plate means, said pressure plate means including a distance holder and a pressure plate, said distance holder engaging one of said strap sections and said pressure plate engaging said other strap section when providing tension to said packing strap, said swivel lever connected to said tensioning wheel by connector means for selectively rotating said tensioning wheel, and said swivel lever includes an actuator for selectively engaging said opening means on an actuator area wherein said actuator upon engagement with said opening means at said actuation area causing said opening means to disengage said closing means and to disengage said pressure plate means from said sections of said packing strap.
