Appeal No. 98-1184
Application 08/593,670
tangential to the web in the direction of web movement.
Claims 1, 2 and 7 are illustrative and reads as follows:
1. A method for treating a crease sensitive web,
comprising the steps of:
supplying a web to a treatment zone at a tension of
between about 1 pound force per linear inch of web width and
about 5 pounds force per linear inch of web width; treating
the web by projecting at least one high velocity stream of
gaseous fluid against only one side of the web substantially
tangential to the path of travel of the web and in the
direction of travel of the web such that a series of saw-tooth
waves are formed in and move along the web in the direction of
travel of the web; and removing the web from said treatment
zone.
2. The method as recited in Claim 1, wherein the tension
of the web subsequent to treatment by said gaseous fluid is no
greater than approximately one-half of the tension at which
the web is supplied to the treatment zone.
7. A method for treating a crease sensitive web,
comprising the steps of:
supplying a web of material to a treatment zone at a
tension of about 1 pound force per linear inch of web width
and about 5 pounds force per linear inch of web width, wherein
said material is characterized by a ratio of tensile stiffness
to bending stiffness of greater than 0.5 CM ; treating the web-2
by projecting at least one high velocity stream of gaseous
fluid against only one side of the web substantially
tangential to the path of travel of the web and in the
direction of travel of the web such that a series of saw-tooth
waves are formed in and move along the web in the direction of
travel of the web; and removing the web from said treatment
