Strap-finishing Patents (Class 69/17)
  • Patent number: 11850765
    Abstract: A cutting apparatus for forming fingers in an end of a belt is provided and includes a blade for cutting the belt and a table for positioning the belt below the blade. The cutting apparatus includes an actuator that is connected to the blade via a primary shaft. The actuator is also connected to the table via both a secondary shaft and a cam assembly. Rotation of the actuator causes the primary shaft to continuously reciprocate the blade in upward and downward directions. Rotation of the actuator also causes intermittent movement of the table that includes both translation of the table to index the belt relative to the blade, and pivoting of the table to change an angle of the belt relative to the blade.

  • Patent number: 5941101
    Abstract: A belt edge burnishing machine for burnishing the edges of a plurality of belts simultaneously. The belt edge burnishing machine comprises a conveyor and at least one buffing wheel positioned above the conveyor which is rotated about an axis parallel to the ground and to the conveyor. The belts are stacked on an edges finish board with the unfinished edges facing up. The edge finish board is placed on the conveyor which conveys the plurality of belts through the burnishing machine. As the belts pass beneath the rotating buffing wheel, the buffing wheel contacts all of the exposed unfinished edges, thus buffing the edges smooth.
