<p>An apparatus is disclosed for producing a band of generally rectangular cross section having at least two layers of material comprising means for advancing a first band along a predetermined linear path and means for guiding a second band into layered alignment with said first band including a roll (23, 32) around which said second band is partially wrapped prior to contacting said first band, the second band having an initial tangential contact position with said roll along a line on the surface thereof extending generally axially with respect to the roll, the roll being tiltable in a plane defined by the axis thereof and the initial tangential contact position of the second band, whereby the lateral take-off position of the second band may be controlled by tilting the roll so as to guide it into aligned juxtaposition with the first band to form a layered, substantially rectangular tow band.</p> |
