PACKING IN CASKS 189 



can, is a reliable safeguard against wrinkles and rust spots, which 

 are so prone to appear where paste is used exclusively, and which 

 mar the attractiveness and neatness of the package. The labeled 

 cans which now leave the machine over a chute slanting from it, 

 can be cased immediately without risk. The use of tables and 

 fans to dry the labels, often found necessary in the case of 

 mechanically applied paste, js made superfluous, and time, labor 

 and space are saved. 



Capacity of Labeling Machines. In the latest improved 

 types of labeling machines the capacity has been greatly in- 

 creased over that of the older models. One properly operated 

 hand-driven machine will now label on an average from 40,000 

 to 50,000 cans and a power-driven machine will average from 

 60,000 to 70,000 cans per ten-hour day. 



PACKING. 



The labeled cans are packed in cases holding from six to 

 ninety-six cans, according to the size of the cans. (One case 

 holds six 1-gallon cans; forty-eight 14-, 15-, 16-, and 20-ounce 

 cans ; or seventy-two to ninety-six 8-ounce cans.) 



The sides, bottom and top of the cases should be of material 

 about three-eighths of an inch to one-half inch thick, the ends 

 three-fourths of an inch to seven-eighths of an inch thick. The 

 cases are usually bought in the "knock-down" shape and are 

 made up in the factory. Sixpenny cement-coated wire nails are 

 most suitable for this purpose. The cases are most economically 

 nailed by the use of nailing machines, which nail one entire side 

 or one side and one end simultaneously. The cans are usually 

 placed into the cases direct from the labeling machine. In some 

 factories, packing machines, which pack twenty-four medium- 

 si'/e cans in one operation, are used. Formerly condensed milk 

 cans were packed exclusively in wooden cases. Within the last 

 few years the use of paste-board and fibre boxes has been adopted 

 in many condenseries. These boxes are proving very serviceable 

 for domestic trade, and prior to the price advance on paper ma- 

 terial caused by the world war, they made possible a considerable 

 saving in the cost of the package. 



Mechanical can casers, operating with the labeling machine, 

 are now available and are used to advantage in many condens-
