rolls B and C. It passes around roll C, then between this and the 

 roll D, where it is sheeted to the proper thickness. Adjacent to 

 the lower roll D, is a pattern roll /I, in which the patterns are 

 cut of the proper shape to form the shoe uppers. The roll F

has supplementary patterns raised above the surface to fit in 

 those on roll £. These two rolls form cutting dies, which cut 

 the patterns from the sheet of rubber. A strip of fabric G from 

 the roll // passes between rolls E and F with the rubber. The 

 rubber and fabric are pressed together over the area of the pat- 

 terns ; but since those portions of the rolls between the patterns 

 do not contact, the two sheets are not united at these points, and 

 are pressed together only within the limits of the patterns. The 



GREATER SAFETY IN THE RUBBER FACTORY 

 That tliere is no basis nowadays for the old-time claim tliat 

 work in a rubber shop is more hazardous and unhealtliy tlian 

 in most other factories, was demonstrated by Sidney M. Schott, 

 of Morgan & W right, Detroit, Michigan, in an address given 

 at the meeting of the Rubber Division of the Ninth National 

 Safety Congress held in Milwaukee, Wisconsin. 



Rubber manufacturing concerns, from the president down to 

 the humblest employe, are learning that safety pays, and an in- 

 tensive campaign for safety, started more than a year ago under 

 the auspices of the Rubber Division, is already bearing good 

 fruit. The successful executive today is the one who insists 

 upon all processes and machinery being made as safe as possible, 

 even going to the extent of refusing to buy 

 etiuipment that lacks all possible safeguards. 



Accident statistics are being carefully stand- 

 ardized so that causes can be more definitely 

 determined and proper remedies applied. Firms 

 now engage in friendly rivalry to see which 

 will produce the best percentage record of im- 

 provements in casualty lists. Workers arc be- 

 ing educated with bulletins showing how the 

 lost-time and minor accidents may be easily 

 avoided ; and the Rubber Division is preparing 

 standard safety rules for mill and calender 

 rooiTis, tire-building rooms, cement shops, etc. 

 The same division has made recommendations 

 as to the best types of floors for mill and cal- 

 ender rooms and is working on standards to 

 insure the safe working of these machines. 

 Knowing that the larger organizations are well 

 able to take care of themselves in the matter, 

 the Rubber Division is making a greater effort 

 than ever to enlist the interest of and assist the 

 smaller concerns which need guidance and 

 hearty cooperation.
