Abstract (en)
[origin: US2005173585A1] A core gluing device for a rewinding machine comprises a conveyor ( 1 ) designed to convey cores ( 10 a, 10 b, 10 c) along a core conveying surface (A-A), a gluing unit ( 2 ) comprising a first gluing roller ( 22 ) which picks up the glue from a glue container ( 20 ) and a second gluing roller ( 26 ) opposed to the first gluing roller, so that each core ( 10 a, 10 b, 10 c) can pass between the two gluing rollers ( 22, 26 ) for application of a trace of glue ( 100 b, 100 c) on it. The gluing rollers ( 22, 26 ) are driven at different speeds to control the width of the trace of glue to be applied to the core, and positioning devices ( 4 ) are provided, arranged downstream of the gluing devices ( 2 ) and upstream of a log winding unit ( 6 ) of the rewinding machine for the correct positioning of the core ( 10 c) with the related trace of glue ( 100 c), before insertion between the winding rollers.
