Abstract
A web tension adjustment device includes a pair of guide rollers and a dancer roller. The two guide rollers are spaced at least in a gravity direction and guide continuous paper in transfer. The dancer roller moves within a moving range along a guide shaft extending in a direction intersecting a rotation axis distance direction of the pair of guide rollers at an acute angle, rolls on the continuous paper transferred between the pair of guide rollers and gives tension to the continuous paper, the tension corresponding to an amount of moving from a position between the pair of guide rollers along the guide shaft.
Claims6
A web tension adjustment device, comprising:
- a pair of guide rollers spaced at least in a gravity direction and guiding a web in transfer;
- and
- a dancer roller that moves within a moving range along a guide extending in a direction intersecting a rotation axis distance direction of the pair of guide rollers at an acute angle, rolls on the web transferred between the pair of guide rollers and gives tension to the web, the tension corresponding to an amount of moving along the guide from a position between the pair of guide rollers.
A web winding device, comprising:
- a winder that winds a web;
- and
- a web tension adjustment device used for a tension adjustment mechanism that adjusts tension of the web to be wound by the winder,
- wherein the web tension adjustment device includes:
- a pair of guide rollers spaced at least in a gravity direction and guiding the web in transfer;
- and
- a dancer roller that moves within a moving range along a guide extending in a direction intersecting a rotation axis distance direction of the pair of guide rollers at an acute angle, rolls on the web transferred between the pair of guide rollers and gives tension to the web, the tension corresponding to an amount of moving along the guide from a position between the pair of guide rollers.
