GENERAL INSTRUCTIONS AS TO WORKING OF ROVING. 161 GENERAL INSTRUCTIONS AS TO WORKING OF ROVING. There is no doubt that the roving is one of the most importantmachines in a jute mill. Two parts of this machine require continualattention—namely, the differential motion and traverse gear, and thescrews working the gill bars. First, in reference to the differential motion, a description of thishaving been given by Mr Joseph Hovell, whi
