Abstract
A process for treatment of a web by means of impingement by high velocity gaseous fluid is provided. The process constitutes the provision of a web to a treatment zone at a tension of between about 1 and about 5 pounds force per linear inch of web width. In the treatment zone the web is subjected to the imposition of high velocity gaseous fluid substantially tangential to the web and in the direction of travel by the web through the treatment zone, such that a series of saw-tooth waves are formed in and move along the web in the direction of travel by the web. An apparatus for carrying out the process is also provided.
Claims1
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 with the tension of the web subsequent to treatment by a gaseous fluid being no greater than approximately one-half of the tension at which the web is supplied to the treatment zone;
- 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.
