Device for manufacturing a shutter link for a multi-link overhead shutter or roller blind

A device for manufacturing, in a continuous manner, shutter links for a multilink overhead-shutter or roller blind, said shutter links each comprising a pair of leaves which are bent into mutual engagement along their opposite longitudinal edges and which are shaped to form a cavity between said edges, said cavity being filled with a heat insulating compound, said device comprising a supply stand supporting two metallic strip coils, a first roll forming machine located along a path extending from said supply stand, said roll forming machine being provided with drive and shaping rolls to drive metallic strips from said strip coils and to shape the strips into the shape of the leaves of the shutter link elements and a second roll forming machine also located along said path beyond said first roll forming machine, said second roll forming machine having first pressure rolls adapted to force the shaped strips together along one longitudinal edge thereof, a spreading element positioned to extend between and force apart the other longitudinal edges of said strips, a filling nozzle positioned downstream of said spreading element for injecting a heat insulating compound between said forced apart other edges and into the cavity between the leaves and closing rolls arranged downstream from said filling nozzle to force the shaped strips together along said other longitudinal edge.
