Abstract:
1. A crossover switch for guiding pushers traveling in a downstream direction which have respective guide elements, said crossover switch comprising: a. a body defining a first divert guide path and a second divert guide path, said first and second guide paths configured complementarily to said guide elements, said first and second guide paths intersecting with each other at an intersection; b. a first actuator associated with said first divert guide path, said first actuator being moveable between a first position at which a portion of said first actuator is disposed within said first divert guide path and a second position at which there is clearance for said guide elements to pass through said first divert guide path; c. a second actuator associated with said second divert guide path, said second actuator being moveable between a first position at which a portion of said second actuator is disposed within said second divert guide path and a second position at which there is clearance for said guide elements to pass through said second divert guide path; d. a switch arm pivotable about a first axis between a first switch position at which said first divert guide path is blocked by said switch, and a second switch position at which said second divert guide path is blocked by said switch, said first axis being disposed downstream of said intersection; and e. said first and second actuators being operably connected to said switch so that movement of said first actuator from its first position into its second position moves said switch into said second switch position, and that movement of said second actuator from its first position into its second position moves said switch into said first switch position.
