ABSTRACT:
An apparatus for manufacturing insulating construction profiles having two metal profiles spaced from each other to define a channel filled with an insulating compound includes a supporting table to support a plurality of metal strands successively positioned in advanced movement along the table by transport rollers. Each strand includes a pair of metal profiles spaced from each other and connected with a temporary bridging strip in their advancing path. A first pouring device is positioned in the path of the advancing profiles to fill an insulating material into the channel between two metal profiles in each strand to form a first insulating core and a second pouring device is provided to introduce insulating material into the same channel to form a second insulating core. Between the two pouring devices a strip supply roll, a guide arrangement and a pressure roller are arranged to apply a separating strip between the two insulating cores which is vertically spaced from the temporary bridging strip. A cutting arrangement is provided to remove the temporary bridging strip.
