Method of making a bird repellant structure and blank for use therein

A method of manufacturing a bird repellant structure, said method comprising:

• punching into a continuous base strip a plurality of first diagonal slots of substantially the same dimension, said slots being disposed substantially equidistant from the center longitudinal axis of the base strip;
• punching into the continuous base strip a second diagonal slot of substantially the same dimension as the first diagonal slots, the second diagonal slot being substantially on the center longitudinal axis of the base strip and parallel to one of the first diagonal slots;
• punching into the continuous base strip a plurality of third diagonal slots, the third diagonal slots being lesser in dimension than the first and second slots, and each third diagonal slot being parallel to one of the first diagonal slots;
• cutting into the continuous base strip a first finger extending from each of the diagonal slots such that a leading end of each first finger is formed by a portion of the diagonal edge of each respective slot;
• cutting into the continuous base strip a second finger extending from each of the diagonal slots such that a leading end of the second finger is formed by a portion of the diagonal edge of each respective slot;
• punching a plurality of first lift bars into the continuous base strip, the first lift bars extending longitudinally from each first diagonal slots such that a leading end of each first lift bar is formed by the diagonal edge of each first diagonal slot and includes the first and second fingers thereof;
• punching a second lift bar into the continuous base strip, the second lift bar extending longitudinally from the second diagonal slot such that a leading end of the second lift bar is formed by the diagonal edge of the second diagonal slot and includes the first and second fingers thereof;
• and
• punching a plurality of third lift bars in the continuous base strip, the third lift bars extending longitudinally from each third diagonal slot such that a leading end of each third lift bar is formed by the diagonal edge of each third diagonal slot and includes the first and second fingers thereof.

A blank base for the manufacture of a bird repellant structure, said blank base comprising:

• a continuous base strip with a plurality of cut-out diagonal slots disposed therein;
• said plurality of diagonal slots including first slots, a second slot and third slots;
• said first slots including two apposing diagonal slots of substantially the same dimension disposed substantially equidistant from a center longitudinal axis of said base strip;
• said second slot being substantially the same dimension as said apposing first diagonal slots and substantially on the center longitudinal axis of said base strip, said slot being parallel to one or the other of said first diagonal slots and being disposed between said first slots such that a leading of the second slot rests approximately on a lateral line extending between the terminal ends of the first diagonal slots;
• said third slots being lesser in dimension than the first and second slots and disposed approximately equidistant from said second slot, said third diagonal slots being parallel to one of the first diagonal slots and disposed such that the terminal end of the third slots rest approximately on a lateral line extending along the terminal end of the second slot.
