摘要

The cladding is built by a sheet blank (10), which has a breadth larger than that of a fluorescent stick. The blank has contact arrangements (11, 12) at its longitudinal edges. The contact arrangements are insertable to each other after rolling of the blank around its longitudinal direction, in order to hold the blank in roll up condition and in cladding forming condition.
