ABSTRACT:
In a process for manufacturing a bow rake, an outer plastic encasement is molded over a structural skeleton to form a cross-head including a handle-receiving socket and a plurality of spaced-apart tines. An elongated claw is pressed into an end of each tine, and an end of a handle is securing within the handle-receiving socket. In manufacturing the cross-head, one or more voids in the structural skeleton are filled with a selected flowable filler material which provides a structural backstop to maintain the shape integrity of the hollow skeleton during the molding step. Some or all of the filler material is removed from the skeleton subsequent to the molding step. Prior to pressing the claws into the tines, the claws are heated and then secured on a ram. The cross head is placed in a stationary jig in alignment with the ram, and the heated claw is then pressed into the selected tine. A similar process is utilized to connect the handle to the cross-head.
