Abstract

Official abstract text for this publication.

A roll device includes a feeding roll in which a web is wound, a winding roll configured to wind the web fed from the feeding roll, and a partition disposed between an outermost winding portion of the web fed from the feeding roll and an inner winding portion of the web overlapped with the outermost winding portion.

First claim

Opening claim text (preview).

What is claimed is: 1. A roll device comprising: a feeding roll in which a web is wound; a winding roll configured to wind the web fed from the feeding roll; and a partition inserted between layers of the web of the feeding roll, wherein the partition is disposed to separate an outermost layer of the web of the feeding roll from an inner layer of the web overlapped with the outermost layer, wherein the web is fed upward from the feeding roll, and a leading end of the partition is disposed lower than an axis of the feeding roll in a vertical direction. 2. The roll device according to claim 1 , wherein the partition has a shape of a sheet. 3. The roll device according to claim 1 , wherein the leading end of the partition is inserted between the outermost layer and the inner layer of the web in a direction counter to a winding direction in which the winding roll winds the web fed from the feeding roll. 4. The roll device according to claim 1 , wherein the partition is flexible. 5. The roll device according to claim 1 , wherein a coefficient of static friction between the partition and the web is smaller than a coefficient of static friction between the outermost layer and the inner layer of the web. 6. A roll apparatus comprising the roll device according to claim 1 . 7. The roll apparatus according to claim 6 , wherein the web is a wiper.
