ABSTRACT:
Plates for forming heat exchanger tubes are assembled into pairs by an assembly machine having two cooperating rotors, each having a plate input, and a feed mechanism transfers plates of different types from stacks of plates to the machine in a desired order. A conveyor belt for each rotor carries plates from a number of magazines above the conveyor to the rotor. Escapements on the magazines drop plates onto the conveyors. A controller actuates the escapements in a sequence to arrange the plate types on the conveyor in the correct order, and also controls indexing of the conveyor and the assembly machine. Rollers associated with each rotor affords a conveyor return which does not interfere with the assembly operation.
