297. Cement Splice. The most satisfactory splice is 

 one which keeps the belt at the joint the same in shape and 

 general conditions as at any other point. Such a splice is 

 made by squaring the ends (Fig. 327), and then carefully 



dressing the joining surface, as 

 indicated in Fig. 328, making 

 the thickness at the squared 



end as thin as possible a

A cement splice can easily be made without removing belt 

 from pulleys. Tighten belt with a belt clamp (Fig. 329), fit- 

 ting it squarely on the belt. 



The length of the splice should be V greater than the 

 width of the belt, up to 

 12 ", which is regarded as 

 the maximum length for 

 splicing a belt, no matter 

 how wide it is. When the 

 clamp has pulled the belt to the desired tension, cut 

 one end to make the lap V longer than the width of 

 the belt. Lay the end of the belt on a board, the end 



of the two coincid- 

 ing, and plane the 

 lap joint with a 

 sharp, small plane
