Angle plate package having a single strap

1. A stacked package of angle plates for use in association with a device for assembling individual ones of said angle plates into receptive flanges of HVAC duct sections, comprising:

a plurality of angle plates, each having two legs joined at an apex forming a right angle, forming said stacked package whereby said legs of each of said ones of said angle plates within said stacked package are substantially aligned with all other ones of said angle plates within said stacked package;

a strap zone located proximate to said apex of each of said angle plates from said apex to a point 25% along the length of each of said legs;

a single tensioned strap extending around each of said angle plates in said stacked package, said single tensioned strap located within said strap zone and exerting a preselected amount of tension sufficient to restrain each of said individual ones of said angle plates within said stacked package, facilitating the handling of said stacked package of angle plates as a unified whole for insertion within a supply hopper of said device for assembling individual ones of said angle plates into receptive flanges of HVAC duct sections.

2. The stacked package of angle plates as described in claim 1 , wherein said single tensioned strap restrains at least one of lateral and rotational displacement of individual ones of said angle plates within said stacked package.

3. The stacked package of angle plates as described in claim 1 , wherein the combination of said tension of said single tensioned strap and said location of said strap within said strap zone restrains at least one of lateral and rotational displacement of individual ones of said angle plates within said stacked package.

4. The stacked package of angle plates as described in claim 1 , wherein each of said angle plates further comprises a raised perimeter along a portion of at least one of said legs and said corner.

5. The stacked package of angle plates as described in claim 4 , wherein said raised perimeter is discontinuous and forms a recess at said apex of each of said angle plates.

6. The stacked package of angle plates as described in claim 5 , wherein said recess is formed at a corner of each of said angle plates.

7. The stacked package of angle plates as described in claim 5 , wherein said recess is selected from the group consisting of flat and angular.

8. The stacked package of angle plates as described in claim 7 , wherein said flat recess is located on an external perimeter of each of said angle plates at said apex and receives said single tensioned strap along a surface of said flat recess.

9. The stacked package of angle plates as described in claim 1 , wherein each of said angle plates further comprises a plurality of projections proximate to said apex forming a space which receives and restrains said single tensioned strap from lateral movement along said legs.

10. The stacked package of angle plates as described in claim 9 , wherein said apex of each of said angle plates further comprises a flat recess aligned with said plurality of projections, said flat recess and said space between said projections combining to receive and restrain said single tensioned strap at said apex of said angle plates.

11. The stacked package of angle plates as described in claim 1 , wherein said single tensioned strap is located at said apex of each of said angle plates.

12. The stacked package of angle plates as described in claim 1 , wherein said single tensioned strap is located along one of said legs of each of said angle plates in said stacked package.

13. The stacked package of angle plates as described in claim 1 , wherein the number of angle plates is preselected from the group consisting of: (i) less than or equal to 25, (ii) less than or equal to 40 and (iii) less than or equal to 80.

14. The stacked package of angle plates as described in claim 13 , wherein said single tensioned strap exerts a force of 4 foot pounds on said angle plates.

15. The stacked package of angle plates as described in claim 1 , wherein said strap exerts a force of 4 foot pounds on said angle plates.

16. The stacked package of angle plates as described in claim 1 , wherein each of said angle plates further comprises at least one of:

(i) a raised perimeter along a portion of at least one of: said legs and said corner; and

(ii) a plurality of projections proximate to said apex forming a space which receives and restrains said single tensioned strap from lateral movement along said legs; and

wherein at least one of said projections and said raised perimeter of each of said angle plates retards nesting of said angle plates.

17. The stacked package of angle plates as described in claim 1 , wherein said single tensioned strap is further comprised of plastic material.

18. The stacked package of angle plates as described in claim 17 , wherein said plastic material is linear and formed into a loop by a weld.

19. The stacked package of angle plates as described in claim 18 , wherein said weld is formed by overlapping ends of said single tensioned strap and one end extends beyond said weld to form a tab facilitating destruction of the weld.

20. The stacked package of angle plates as described in claim 18 , wherein the location of said weld on said stack is preselected from the group consisting of the: top and side of the stack.

21. The stacked package of angle plates as described in claim 17 , wherein said plastic material resists stretching.

22. The stacked package of angle plates as described in claim 1 , wherein said strap zone is generally aligned with an opening in a supply hopper provided to receive and restrain said stacked package, facilitating access to said single tensioned strap from outside of said supply hopper.
