STRAP TENSION SENSING AND CUT OFF MECHANISMABSTRACT OF THE DISCLOSURE:A tension sensing and cut off control mechanism whichoperates independently of the mechanism for drawing tight aclosed loop bundling strap placed about objects to be bundled.In a stationary block afixed to one end of a tool housing isplaced within a movable block held stationary by a displaceablepin. Adjustable loading means engage said pin to controlits movement based on the tension to be applied to thestrap. Below the established load a separate pawl mechanismdraws the strap up about the bundle. When the load on thepin is exceeded, the movable block is moved by the straphead causing a blade means to sever the strap adjacent thehead and all parts return to their original positions.
