336 BELTS AND BELTING 



may be used, as indicated in C, Fig. 333. This will make 

 a less substantial lacing. To lace the belt, place a lace 

 thru the middle holes from the pulley side holes 1 and 

 2 (Fig. 334) allowing the two ends of the lace extending 

 on the side of the belt opposite the pulley to be as nearly 

 as possible the same length. The end which extends 

 thru hole No. 2 is put thru hole No. 3, then thru holes 

 Nos. 4, 5, 6, 7 and 8, passing thru the first row of holes on 

 one part of the belt and thru the second row on the other 

 part; then to No. 9, crossing the belt joint, and back 

 thru holes Nos. 10, 11, 12, 13 and 14; then thru hole No. 

 15, and, finally, thru a tie hole, No. 16, when the end 

 should be cut off about 3/8" from the belt. The second end 

 of the lacing should follow a similar course, and, upon its 

 return, should go thru hole No. 2, and, finally, thru the 

 tie hole, No. 30. Note that on the side opposite the pul- 

 ley, the large crosses or plies are over the short ones. 

 This is desirable to reduce friction and wear. Always 

 pull the lacing taut, but do not buckle the belt. 



303. Double-Cross Lacing ; One or Two Rows of Holes 

 Punched on Each End. For this problem, two laces rather 

 than one must be used. It is not deemed necessary to give 

 detailed instructions for a double-cross lacing, as the instruc- 

 tions given for Problem 1 and Problem 2 apply, except as in- 

 dicated below. 



Double-cross lacing is similar to single-cross lacing except 

 that two strands of lace are drawn thru each hole and that 

 the holes are spaced twice as far apart across the belt. It is 

 necessary that the two strands be drawn equally tight. 



This method of lacing a belt is quicker than the single-
