Abstract
The cover for a weaving machine is formed, in part, of flexible mats of sound-insulating material which can be raised or lowered in the manner of a window shade. In one embodiment, the rollers on which the flexible mats are mounted are positively driven to raise or lower the mats while a toggle means is used to support the mat over the machine frame. In addition, the rollers are mounted in a carriage which can be moved to one side while the sides of the cover are opened to allow access to the machine from above. In another embodiment, the flexible mats are in an accordion or pleated form and are raised or lowered via an endless chain.
