Guide with adjustable nose cone

摘要

A guide is adapted to be positioned for encirclement by a helical formation of rod rings free falling from the delivery end of a conveyor. The guide comprises a vertically projecting mandrel terminating at its upper end in a nose cone. The nose cone has a horizontal profile defined in part by at least one element having an outer edge separated by a variable radial distance from a central axis of the mandrel.

1. A guide adapted to be positioned for encirclement by a helical formation of rod rings free falling from the delivery end of a conveyor, said guide comprising:
a vertically projecting mandrel terminating at its upper end in a nose cone, said nose cone being non-rotatable and having a horizontal profile when viewed from above defined by a plurality of angularly spaced elements, each of said elements having an outer edge separated by a radial distance from a central axis of said mandrel; adjustment means for changing said horizontal profile by increasing the radial distance of at least one of the said elements; and said at least one element is adjustably mounted on said nose cone, and wherein said adjustment means serves to shift said at least one element outwardly from a central axis of said mandrel.
