Abstract
A drying system and method of operating the drying system to dry a printed shrinkable web are disclosed. A web transport is adapted to convey the printed web between a heating apparatus and a cooling apparatus. The heating apparatus directs heat toward the web and the cooling apparatus concurrently chills the web. A temperature sensing device is adapted to develop an indication of a temperature of the web and the controller is adapted to adjust a temperature of at least one of the heating apparatus and the cooling apparatus in accordance with such indication.
Claims20
A dryer system, comprising:
- a heating apparatus;
- a cooling apparatus;
- a first temperature sensing device;
- a second temperature sensing device;
- a controller;
- and
- a web transport adapted to convey a printed shrinkable web between the heating apparatus and the cooling apparatus;
- wherein the heating apparatus is adapted to direct heat toward the web and the cooling apparatus is adapted to concurrently chill the web, the first temperature sensing device is adapted to develop a first indication of a temperature of the cooling apparatus, the second temperature sensing device is adapted to develop a second indication of a temperature of the printed shrinkable web, and the controller is adapted to adjust a temperature of at least one of the heating apparatus and the cooling apparatus in accordance with the first and second indications.
A method for drying a material deposited on a shrinkable web, comprising the steps of:
- conveying a printed shrinkable web between a heating apparatus and a cooling apparatus;
- operating the heating apparatus to direct heat toward the web;
- operating the cooling apparatus to cool the web concurrently with the operation of the heating apparatus;
- receiving an indication of a temperature of the cooling apparatus;
- reviving an indication of a temperature of the printed shrinkable web;
- and
- adjusting a temperature of at least one of the heating apparatus and the cooling apparatus in accordance with the indication of the temperature of the cooling apparatus and the printed shrinkable web.
