Abstract
A method and device are disclosed for forming and filling tubes containing a product, with the filling process taking place from the longer side of the tube, rather than the shorter side. An elongated product delivery tube contains product diverters that evenly spread out the product, allowing a clean seal in less time. An optional vibrator helps the product to settle quickly. Throughput is increased over the prior art, as well as facilitating improvements in opening the tube and in marketing.
