ROLLER CASSETTE AND ROLLER SYSTEM

The invention relates to a roller blind cassette for receiving a roller shaft and a roller blind that is wound in a storage state on the roller shaft and can be withdrawn from the roller shaft in a longitudinal direction into an operational state through an exit gap (312) of the roller blind cassette, with a housing that has a continuously slotted hollow profile (210) extending in a main extension direction transverse to the longitudinal direction, the slot (312) of which forms the exit gap (312) of the roller blind cassette. According to the invention, it is provided that a connecting web extending over the slot (312) extends from at least one edge region (312a, 312b) at at least one of the end faces (310a, 310b), which connecting web is an integral part of the hollow profile (310) and whose distal end is fastened to the opposite edge region, or connecting webs (315a, 315b) extending over the slot (312) extend from both opposite edge regions (312a, 312b) at at least one of the end faces (310a, 310b), which connecting webs are each an integral part of the hollow profile (310) and whose distal ends are connected to each other.
