(f) The rotary veneer machine is now also used to cut 4-inch or 4VL.-inch slack gum staves. 



(g) The stave equalizer trims the ends and gives the staves the proper length. It consists of two 

 circular saws and a tilting bed or a carriage. 



(h) Stave listers or jointers edge the staves in 

 such a way that the edges coincide with a plane through 

 the axis of the barrel. 



Staves for export are straight listed and without bilge. 



The stave jointer is either a circular swing saw; or 

 it consists of two circular saws ; or of a number of inclined 

 knives held by cutterheads; or of one knife running in a 

 vertical sash frame; or it consists of two large, vertical, 

 concave wheels in rapid rotation. Whether the one or 

 the other wheel is to be used depends on the grain of the 

 staves. Staves must be jointed with the grain. The wheels 

 carry, close to their circumference, a number of knives. 

 The stave is held by dogs in an inclined position, and is 

 forced into the cavity of the wheel so as to form a secant 

 by which the knives pass with a shearing stroke. The 

 proper bilge and the proper joint are thus obtained simul- 

 taneously. 



(i) In the "STAVE planer," a steel pattern passing stave jointer. E.& B. Holmes Machinery 

 through the machine with the stave lifts the cutters in such 

 a way as to allow the shoulders of the staves to retain 

 a greater thickness than the middle of the staves. 



Beer barrel staves require a heavier shoulder 

 heavier thickness than wine barrel staves. 



Gebriider Schmaltz, Offenbach, Germany have 

 on the market a machine planing the inside of the 

 barrel, before it receives the heading.
