ABSTRACT:
A tube transfer device which includes a tube conveyor for transporting processed tubes from an entry location to an exit location thereon. The tube conveyor includes a plurality of first tube holders thereon which are adapted to hold the processed tubes so that axes thereof will extend parallel to one another and be laterally spaced apart a first distance from one another at the aforesaid entry location. A movable tube shuttle is provided for shifting processed tubes between a first position and a second position located adjacent the aforesaid entry location to the tube conveyor. The tube shuttle includes movable second tube holders adapted to receive the processed tubes when at the aforesaid first position and while maintaining a second distance between the processed tubes. The tube shuttle also includes structure for varying the lateral spacing between the processed tubes on the second tube holders from the second distance to the first distance and in response to a movement of the tube shuttle between the first position and the second position so that the processed tubes will be spaced at the first distance from one another when the tube shuttle is at the entry location to the tube conveyor. A device for transferring the tubes on the tube shuttle to the tube conveyor is provided.
