Fence Components and Fences

Abstract

A fence for controlling the movement of animals. The fence comprises an elongate portion which is above ground level and which, in one way or another, make it more difficult for an animal to climb up the fence and/or deter an animal from attempting to climb up the fence. For convenience, the elongate portion is denoted a BB band. Fence components comprising BB bands, and methods for preparing them, are described.

1 . An elongate fence component which comprises
 (1) an elongate band which, when it is part of a fence, is above ground and makes it more difficult for an animal to climb up the fence and/or deters an animal from attempting to climb up the fence (a BB band), and   (2) an elongate portion which comprises apertures and which is attached to one edge of the BB band.   
     
     
         2 . A fence component according to  claim 1  which comprises a single elongate apertured portion attached to one edge of the BB band. 
     
     
         3 . A fence component according to  claim 1  which comprises two elongate apertured portions attached to opposite edges of the BB band. 
     
     
         4 . A fence component according to  claim 1  wherein the BB band is free of apertures. 
     
     
         5 . A fence component according to  claim 1  wherein the BB band is at least partially opaque. 
     
     
         6 . A fence component according to  claim 5  wherein the BB band is colored. 
     
     
         7 . A fence component according to  claim 1  wherein the BB band has an exposed surface which is slippery. 
     
     
         8 . A fence component according to  claim 1  wherein the BB band is a sheet of a polymeric composition. 
     
     
         9 . A fence component according to  claim 1  which is in the form of a roll. 
     
     
         10 . A fence for controlling the movement of animals, the fence comprising an elongate band which runs along the length of the fence above ground and makes it more difficult for an animal to climb up the fence and/or deters an animal from attempting to climb up the fence (a BB band), 
     
     
         11 . A fence according to  claim 10  which comprises an elongate apertured portion which (i) runs along part or all of the length of the fence below the BB band, (ii) is attached to a lower edge of the BB band, (iii) is secured to the ground, and (iv) extends part way up the height of the fence. 
     
     
         12 . A fence according to  claim 11  which comprises a second elongate apertured portion which (i) runs along part or all of the length of the fence above the BB band and (ii) is secured an upper edge of the BB band. 
     
     
         13 . A method of making a fence component according to  claim 1  which comprises attaching the BB band to a substrate which comprises the apertured portion. 
     
     
         14 . A method of making a fence component according to  claim 1  which comprises forming the BB band on a substrate which comprises the apertured portion. 
     
     
         15 . A method of making a fence component according to  claim 1  which comprises, in addition to the lower portion, an elongate upper portion, the method comprising preparing the lower portion, the BB band and the upper portion in a single extrusion method so that they are part of an integrated structure.
