(C) RESAWING. Resaws are either circu- 

 lar or band resaws. 



The use of a resaw involves a great 

 saving, since it takes a fine i\erf and at the 

 same time relieves the work of the main saw. 



A resaw working tandem with the main 

 logsaw is capable of increasing the output of 

 the mill greatly. The C. A. Smith mill at Marsh- 

 field, Oregon uses a quintuple system of five 

 large band resaws in connection with two 

 main saws. 



The feed is automatic and consists, 

 usually, of four rolls. 



Circular resaws have as low as nineteen 

 gauge at the rim and are frequently 

 built as segment saws. 



Band resaws are either vertical 

 or horizontal. The horizontal resaw 

 offers the following advantages :- 



1. It can be used for the simul- 

 taneous passage of several 

 planks. 



2. Pieces of different thickness, 

 and notably slabs, can be 

 fed without change of the 

 rolls. 



The feed in horizontal band re- 

 saws is by travelling bed or by end- 

 less chains. The boards or slabs 

 are held down by pressure rolls 

 overhead.
