Abstract
The means for forming a fabric border is constructed with a cover to cover over the opening in the housing through which the operating element projects. The cover is formed by flange projections on the drive means for moving the operating element or by a separate sleeve-like part having a flanged appendage on the operating element. The cover is intended to prevent dust and lint from entering the housing.
