Abstract From the Canadian patent

A bale wrapping apparatus including a sled with a shallow angle to the horizontal with a trough for receiving bales. A carriage mounted pusher plate driven longitudinally of the trough to push bales through the bale wrapping station, and a delivery apron including an endless belt providing a friction free surface. The sled mounts skis which provide a degree of friction when the sled advances as a reaction of the pressure being placed on the end of the bales by the pusher plate so as to allow compression of the bales.

Why it's free to use

  • Filed June 12, 1996 and granted July 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 12, 2016.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 12, 2018.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
