Abstract
Official abstract text for this publication.
A filament winding apparatus that prevents excessive unraveling of a fiber bundle due to variations in the speed at which the fiber bundle is wound includes a hoop winding device having a wrapping table, a bobbin support unit, a braking unit, a slack removal unit, a detector, and a controller. The slack removal unit absorbs slack caused by the difference between winding and unraveling speeds of the fiber bundle. The detector detects whether the amount of slack absorbed is equal to or greater than or is less than, a predetermined amount. When the amount of slack is equal to or greater than the predetermined amount, the controller increases the braking force of the braking unit for braking rotation of a bobbin. When the amount of slack is less than the predetermined amount, the controller reduces the braking force of the braking unit for braking rotation of the bobbin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A filament winding apparatus winding a fiber bundle onto a surface of a liner with a hoop winding device, wherein the hoop winding device comprising: a wrapping table rotated around an axis of the liner; a bobbin support unit provided in the wrapping table and supporting a bobbin of the fiber bundle; a braking unit braking rotation of the bobbin supported by the bobbin support unit; a slack removal unit absorbing slack caused by difference betwee…
