FEED DEVICES FOR AUTOMATIC MACHINES

摘要

A work stock feed device for automatic machines which comprises a cylindrical body with a bore related to the diameter of work stock to be fed thereby with at least a part of the length of the body at the discharge end separately formed and acted upon by an encircling almost circular web of spring steel and with the bore formed with a taper at each end of the separate part or parts, such that the internal taper provides a lead in for the work stock while that at the end allows reentry of the stock, in arrangement such that work stock on engaging a taper displaces substantially radially the separate part or parts against the action of the spring to enter between such part or parts and the adjacent portion(s) of the body to be gripped thereby.
