Guide with adjustable nose cone
View Patent ↗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.
2. The guide of claim 1 wherein said at least one element is located on a downstream side of said nose cone.
3. The guide of claim 1 wherein said adjustment means serves to enlarge said horizontal profile in the direction of delivery of rings from the end of said conveyor.
4. The guide of claim 1 wherein said at least one element is pivotally adjustable.
5. A guide adapted to be positioned for encirclement by a helical formation of product rings free falling from the delivery end of a conveyor, said guide comprising:
a vertically projecting mandrel having a non-rotatable nose cone at its upper end defined by plurality of angularly spaced fins extending radially from a central axis of said mandrel, said fins defining a horizontal profile as viewed from above; and
adjustment means for enlarging said horizontal profile in the direction of delivery of rings from the end of said conveyor by shifting at least one of said fins outwardly from said central axis.
