  • Transfer feed system
    Patent number: 3978768
    Abstract: Apparatus for transporting work over a predetermined path previously requiring a transporting mechanism of a minimal dimension with respect to the corresponding dimension of the path. A transport mechanism is provided for transporting the work over a portion of the path, which transport mechanism has a corresponding dimension substantially less than the minimal dimension. The work is initially maintained in a position in which it is propelled by the transporting mechanism. A further transporting mechanism is provided, which mechanism also has a corresponding dimension substantially less than the minimal dimension. A transfer mechanism transfers the work from a position in which it is propelled by the transport mechanism into a position in which it is propelled by the further transport mechanism.
