WOOD PULP AND PAPER

number of drums used depends upon the speed of the machine and the 

 weight of the paper. The felt is also used in connection with them to keep 

 the sheet of paper pressed tightly against the hot rolls which are heated 

 by steam introduced from one side. 



After passing through the long series of drying rolls, the paper is run 

 through calenders to produce what is known in the trade as supercalen- 

 dered paper. In this operation the surface of the paper is given a glazed 

 finish. 



Cutting. 



As the paper goes from the driers it may vary from 60 to 156 in. or 

 more in width. It is seldom that this width is desired commercially, so 

 the sheets must be unwound and cut to the desired width and rewound 

 once more. For this purpose a special cutter and winder is used. The 

 paper is then sorted, tested, and wrapped for shipment. 



IMPORTS OF PULP WOODS AND WOOD PULP 



The following table shows the imports of pulpwoods and wood pulp 

 to this country for the years 1914 to 1918, inclusive, according to the fig- 

 ures of the Department of Commerce. Each year of these imports ends 

 on June 30th. Practically all of the importation of pulpwoods is from 

 Canada, whereas the wood pulp comes normally from Sweden and Xor- 

 way as well as from other countries and Canada. The tables show how 

 the war seriously interfered with the imports of wood pulp to this coun- 

 try, since the total amount has decreased markedly from the importation 

 in 1914. 



Most of the imports of pulpwood comes to this country in the peeled 

 condition. The imports of pulp wood have increased during the period 

 of the war. particularly the wood brought in in the peeled condition.
