Abstract
Improvements are provided in a food paste pump, e.g. a tomato paste pump, or an egg mixture paste pump, for an apparatus for the making of an overlapped-folded, filled, rolled, food product. That apparatus includes a supporting frame structure, and a conveyor system supported thereon, the conveyor system passing a plurality of work stations. Intermittent moving means are provided for intermittently moving the conveyor system from one work station to the next work station downstream therefrom. The work stations include a sheet of dough feeding mechanism; a foodstuff loading mechanism; a sheet of dough folding mechanism; a folded sheet of dough rolling mechanism; discharge means; and control means to synchronize the intermittent movement of the conveyor system with the sequential operation of all the above-described mechanisms. At the foodstuff loading mechanism, a pair of the novel food paste pumps is provided. Each pump includes a metering cylinder provided with a T-shaped passage with inflow by means of a combination of gravity flow and suction, and discharge by means of pressure by a pump plunger. Control of the volume of food paste discharged is also provided. The discharge of t…
