THE INDIA RUBBER WORLD 



(October 1, 1919, 



It thus becomes the first duly of the man working on scrap 

 to see that it is collected regularly, that none is allowed to ac- 

 cumulate in corners or under benches, and that it is all weighed 

 and charged correctly. 



DAILY AND WEEKLY REPORTS. 



The figures arc made a basis for daily and weekly scrap re- 

 ports showing the amounts of the different stocks thrown into 

 scrap throughout the plant, the percentage is figured against 

 production, and also the value in dollars and cents. One copy 

 of the daily report goes to the superintendent every night, thus 

 calling to his attention immediately any undue waste and furnish- 

 ing first-hand information for foremen's meetings, and another 

 copy goes to the cost department for analysis. 



The foreman of each department is furnished with a weekly 

 report showing the totals of the daily collections and the per- 

 centage for his dci)arlnieiit. In addition a chart is posted in

each department showing the rise or fall of waste. These charts 

 serve to stimulate an interest in keeping the departmental totals 

 as low as possible and induce a note of competition between de- 

 partments for the best showing. 



METHODS OF REDUCING SCRAP. 

 Frequently the scrap man devises minor changes in the ar- 

 rangement of departments or the routing of material in con- 

 sultation with the superintendent and foremen that will re- 

 duce the scrap. For instance, it was found that by using oil or 

 fish-cloth leaves in books for conveying work to the makers 



the cemented pieces would not stick to the cloth, and much 

 material formerly scrapped because of this was saved. Along 

 the same line it was learned that gum shoe linings became 

 easily crushed and wrinkled when put in cloth books for team 

 makers. Consequently a scheme was devised whereby they

were cemented on tins, placed in a car with grooves about 3- 

 inches apart to fit the trays, and slid in a similar compartment 

 tinder the maker's bench, thus keeping them fresh and in first 

 class condition to be made up the next day. In the cutting room 

 it was discovered that the angle for cutting strips on the bias 

 varied slightly on the drum where the stock was laid off, from 

 the angle on the cutter's block, thus causing scrap ends. This 

 was remedied and more materia! saved. 



THE WASTE CLEARING HOUSE. 



Aher the scrap is collected it is taken to a shed or portable 

 building in the yard reserved for the purpose, where it is ex- 

 amined, baled up when necessary to sell it, and ground up to be 

 used in various ways. Here the scrap man has another function 

 in determining what scrap can still further be used as good 

 material. Occasionally good stock, either intentionally or other- 

 wise, finds its way into the scrap. This must all be returned 

 to the department from which it came, and if there is any evi- 

 dence to show that the act was deliberate, it must be reported 

 to the superintendent. 



While all small parts used in boots, gaiters, and gum shoes, 

 such as facings, toe tips, heel pieces, stays, etc., are cut out of 

 board scrap or cutting ends, the scrap man can very often con- 

 trive additional ways of using material. For example, a gum 

 shoe of new construction called for a cork heel lift : enough 

 ends or scrap from cutting soles of the same material were 

 accordingly brought in from the scrap department and used to 

 cut the entire ticket. Again, the tube department was having a 

 special stock run to cut a small circular reinforcing strip for 

 the air valves when it was discovered that side and end pieces 

 of friction scrap from the shoe factory could be used for this 

 purpose. In the tire department much of the fabric trimmings 

 are used in making beads. Sometimes large sizes of tennis tops, 

 insoles, or shoe linings can be cut down into smaller ones where 

 the defect is slight. 



Judgment must be exercised, however, as very often the labor 

 cost of cutting down this material is greater than the value 

 saved. 



Thus the scrap man must have accurate and complete informa- 

 tion on material and labor costs ; must understand rubber goods 

 manufacturing from \ to Z, and must maintain constant touch 

 with the superintendent and foremen. 



GRINDING SHOE SCRAP. 



With the proper facilities for grinding, any rubber shoe fac- 

 tory can find use for 85 per cent of its waste by converting it 

 into the product. One concern which formerly baled up cloth 

 scrap, especially that with a low percentage of rubber, and found 

 difficulty in locating a market for it, solved the problem by in- 

 stalling in the scrap department a rotary cutter such as that
