Abstract
A machine for making and filling packets has an intermittently fed sheet material which is recurrently severed into packet strips. These strips are successively pushed downwardly by a battery of filling tubes which shift vertically, bear against the sheet strip, and fold it into a vertical trough-shaped receptacle open at the top. After the filling tube battery has moved downwardly, sets of vertically spaced sealing or clamping jaws operate to effect laterally spaced side seals in an upper strip and conjointly create top seals in the lower or preceding sheet strip. Product is metered to the packet strips. The sealed packets are severed from the strip after the sealing operation. The filled packet has outwardly bowed side walls and the juncture of the bottom wall and the side walls will assume a line, the configuration of which is a function of the size and cross-sectional configuration of the filling tubes, providing a unique advantageous form.
