A ROLLER SHUTTER FOR WINDOWS, DOORS AND THE LIKE AND A METHOD OF MANUFACTURING

摘要

In a roller shutter for windows, doors and the like a number of slats (1) of a mainly curved cross-sectional profile are arranged in parallel and secured individually to a flexible web or cloth (3) which forms hinge connections in the interspaces (2) between the slats. The slats (1) are individually secured to said web or cloth (3) by means of an intermediate layer (4) of a thermoplastic material which is in full surface contact with the web or the cloth (3) and with the concave side of the slats (1). The roller shutter may be manufactured by applying to one side of the cloth (3) a coating of thermoplastic material to provide the intermediate layer (4), on top of which the slats (1) are placed in parallel transversely to a forwarding direction for the web or cloth (3) by means of a shaping device (12) which brings the concave side of the slats in surface contact with the thermoplastic intermediate layer (4), the intermediate layer (4) in the interspaces between the slats (1) being impacted with the cloth (3) to a thickness suited for providing said hinge connection.
