combined together. The number of wires which may be placed on one line should 

 vary with the quality of the wool or other material. In long-staple machines, the 

 number may vary from four to ten or more, and in short-staple machines from five 

 to twenty and more per inch. B, B, are two fluted feed-rollers ; c, c, two porcupine 

 combing-rollers, by which the wool is partly combed while passing from the feed- 

 rollers to the surface of the sheeting-drum ; an end elevation of the porcupine 

 combing-rollers on an enlarged scale is given at Jiff. 2147. The teeth c, c, are set in 

 rows, and the rows of one roller take or gear into the spaces between the rows of the 

 other. D is a grooved guide-roller for preventing the wool or other material escaping 

 the combining action. The wool or other material is laid by the attendant evenly upon 

 the upper surface of an endless web G, which works over the under feed-rollers, and 

 a plam roller H, which is mounted in bearings on the front of the machine. The 

 feed-rollers gradually supply the wool thus spread upon the endless web to the two 

 porcupine combing-rollers, where it is partly combed and separated, and being so 

 prepared, it is laid hold of by the teeth of the sheeting-drum, by which it is still 

 further drawn out on account of the greater velocity with which the surface of the 

 sheeting-drum travels. When a sufficient quantity of the wool or other material has 

 been thus collected on the surface of the drum, it is removed by the attendant passing 

 a hooked rod across the surface of the drum, and raising up one end of the sheet, 

 when the whole may be easily stripped off and removed, being then in a fit state for 

 being supplied to the comb-filling machine, next to be described.

A modification of this sheeting-machine is represented in Jigs. 2148, 2149, which 

 differs from it in this, that it is fed from both ends. In this modification a double set 

 of feeding rollers is employed, so that the machine may be fed from both ends.

These rollers are grooved and {rear into porcupine combing rollers, similar to those 

 before described, which are followed by brush-cylinders or grooved guide rollers. A
