A special calender is employed by means of which a sheet of 

 calendered stock is formed with successive depressions along its 

 length, the shape of which depressions is varied according to the 

 character of the finished article. This sheet of stock is then 

 superimposed upon a flat sheet and two sheets are joiucd b)-

pressure arcund the margins of the depressions formed in the 

 -upper sheet, compressed air or other gas being at the same time 

 injected into the space formed by the depressions, in order to pre- 

 vent adhesion of the sheets at the point where the Iiiscuit is to be 

 formed. 



The design of calender and its mode of operation are clearly 

 indicated in the accompanying illustrations. — ^Henry Z. Cobb, New 

 York City, assignor to the Mechanical Rubber Co., of New Jersey.
