BUNCHES.
14. How bunches can be made on spinning frames. By piecing on roving and leaving the end to run through double. By piecing up ends and not twisting on smoothly. By wiping out the roving rack and the waste catching on the roving and running through the rolls. By wiping off thread-boards, waste catching on to the ends and spinning. By rolls not being kept clean and oiled. By spinners not being careful enough when they clean their rolls. By spinners brushing and cleaning their frames. By brushing down over head. By spinners not keeping their clearers clean. The carder should be just as particular about making his roving as the spinner is about making his yarn; then there will be good work all through. A dry front roll will make bunches on spinning frames, and will do the same on speeders. Sweepers should not blow their waste under the frames. Bunches can be made on spoolers by thread guides not being wide enough for the threads to pass through. A bunch will collect and stop the spool. Spooler tenders lift it over on to the spool.
COARSE THREADS.
15. How coarse threads are made. First, by coarse roving; second by spinners letting two roving run through the guide; third, by one end catching on to another and running on to the bobbin; fourth, sometimes where there is two ends on one boss, one end will break and catch onto the other and spin. If the trouble is in the spinning, you untwist the thread and you will find two threads instead of one. If not two threads, the trouble is in the carding room.
CHANGING NUMBERS.
16. When you change from one number to another see that the motion runs right to pack the yarn closely on the bobbin; then have your travelers just heavy enough to keep the ends straight. By running a heavy traveler you pack the yarn harder on the bobbin. I do not believe in running a traveler heavy enough to pull down the ends, but heavy enough to keep the ends straight.
