Embodiment Construction

[0019] Hereinafter, with reference to the accompanying drawings, a description will be given of an embodiment of the present invention.

[0020] Roll-to-roll or roll-to-sheet processes for continuous web handling use non-contact floats to control tension disturbances that occur during transport of the web.

[0021] The present invention relates to the handling of a web formed from a brittle material such as a thin glass web, and more particularly to a tension control device comprising a non-contact float for transporting a web formed of a brittle material and a A continuous web processing method using the device.

[0022] figure 2 The basic principle of the tension adjustment according to the invention is schematically shown.

[0023] The tension adjusting device according to the present invention includes a floating member 320 . figure 2 The floating member 320 shown includes a first ultrasonic vibrator 321 , an ultrasonic generator 322 , a shock absorber 324 and a fixed...

Abstract

The present invention provides a tension control device including a dancer for controlling the tension of a web by applying force to the web, wherein the dancer includes a first ultrasonic vibration unit, the first ultrasonic vibration unit carries out ultrasonic-vibration and applies the force to the web in a non-contact state by applying repulsive force according to the ultrasonic vibration thereof. In addition, the present invention provides a continuous web processing method, comprising the steps of: controlling the tension of the web by using the tension control device; and processing the tension-controlled web.

Description

technical field [0001] The present invention relates to a tension adjustment device and a continuous web processing method using the tension adjustment device, and more particularly, to a tension adjustment capable of adjusting the tension of a web by applying a repulsive force caused by ultrasonic vibration to the web Device and continuous web processing method using the device. Background technique [0002] A web refers to a continuous length of soft material. A web handling system for continuously processing such a web includes a winder, an unwinder, driven rolls, idler rolls, and the like. Continuous processing is usually performed using a roll-to-roll or roll-to-sheet process. Dancer (or jumper) devices are used as a solution to control the tension of the web in both roll-to-roll and roll-to-sheet processes. The float device may be configured to apply a predetermined amount of tension to the web by applying a certain amount of force to the web in one direction using ...
